Ryzom

h1. Adding Game Entities (Armor, Spells etc.)

{{>toc}}

h2. Description

After hours and hours of staring at the xml files and browsing restless through the georges editor, i finally could shed some light into the mysteries of entity creation in "Ryzom Core":http://dev.ryzom.com/wiki/ryzom. There is still much to learn but this is a good point to start to share my knowledge i gathered so far.

So what we're going to do is creating an armor item including an crafting plan and two spells (Heal & Dmg) plus some more spell credits. We're going to put them on the server and add them to some corresponding merchants & trainer.

> *Note 1*: For the sake of simplicity in this guide i oriented myself at the old spells and armor. Of Course, the goal of "Ryzom Core":http://dev.ryzom.com/wiki/ryzom is *not* to rebuild the original Ryzom. But in my opinion it will take some time till we have e.g. some truly new spells as this also relies heavily on source code additions. Until then it should be ok if we create some more samples to get to known with the whole process.

> *Note 2*: Personally i think the current georges editor has much potential, but most times im kind of overwhelmed by the masses of editable informations.

> So i switched to just open the actual xml files and edit them. I decided to do it for this guide as well which also saves me from making a lot of screenshots :) But of course you are welcome to do it all in the offical Nel tool!

h2. Prerequisites

Here is a small list with stuff you should have ready for things to work.

* *Get the source*

[[Getting_Source|Look here for more]]

> *Note*: For windows there are some prebuild binaries for everything (client, server, nel tools, ryzom tools). Look [[WindowsBinaries|here]] to find out more.

* *Client / Server*

Well this should be clear but of course you need a working client to test the additions and a working server with access to it as we have to add files on it. There are a bunch of tutorials in the wiki for the plattform of your choice. E.g.:

** [[BuildForLinuxCMake| Linux]]

** [[BuildForMacCmake| Mac OS X]]

** [[EverythingWindows| Windows]]

* *Char with admin rights*

Create a character on your server and grant it some privileges. 

This can be done by using the EGS ([[ServiceArchitecture|Entity Game Service]] - part of the server) command "@setPriv 1 :DEV:@" when the corresponding user is logged into the Client, or by directly altering the corresponding table entry for your character in the mysql database on the server.

> *Note*: If you have more than one character on your server you need to change the EGS command to "@setPriv x :DEV:@" where x is the id of the char found in the mysql database

* *NeL tool "make_sheet_id"* 

This tool is needed to create the *sheet_id.bin* file which is residing in *$RYZOM_HOME$/code/ryzom/common/data_leveldesign/leveldesign/Game_elem*. Therefore build it and make it ready for use. It can be found in *$RYZOM_HOME$/code/nel/tools/misc/make_sheet_id*.

Use it with the following syntax to build your sheet_id.bin:

> @ make_sheet_id_r -oL:/leveldesign/game_elem/sheet_id.bin L:/leveldesign/game_elem L:/leveldesign/game_element L:/leveldesign/world@

> *Note*: To get working make_sheet_id tool you need set allowed extensions or simply just delete or comment _ExtensionsAllowed = { "sample_config" };_ line in *$RYZOM_HOME$/code/nel/tools/misc/make_sheet_id.cfg*

* *Ryzom tool "sheets_packer"*

This tool is needed to build the *.packed_sheets* files from the contents in your leveldesign directory. It can be found *$RYZOM_HOME$"/code/ryzom/tools/sheets_packer*. Build it and make it ready for use. When executing, it will default create the .packed_sheets in *$RYZOM_HOME$"/code/ryzom/client/data*.

* *Ryzom assets*

Its really nice to have the ryzom media assets available. E.g. the Interfaces directory contains all the icons for spells and stuff. You could search for them online at http://media.ryzom.com/ but having them locally is much faster. Bear in mind that all assets, if extracted, are like 11GB in 26k files

* *bnps*

For creating armor its nice to have some of the bnps available unpacked to look for nice shapes you want to use. Download the "Open Ryzom Client":http://sourceforge.net/projects/ryzom/ extract it and look into the data directory. There you will find all the .bnp files. Use the NeL tool *bnp_make* to unpack the files. The easiest way to do so is to copy the desired bnp and the executable in a directory and using following command. This will create a directory with the name of the file and unpack all contents there.

> @bnp_make /u desired_bnp.bnp@

* *sbrick_words_en.txt / skill_words_en.txt / item_words_en.txt / sheets.txt*

It comes in handy if you have these files open. The first three can be found in the *$RYZOM_HOME$/code/ryzom/server/data_shard/language* directory. They are needed later to find the correct skill families and item names (more on that below).

The fourth file gets created if you repack your sheets with the mentioned sheets_packer tool. It contains a human readable overview of the contents of the sheets_id.bin and can be used to find out correct file naming as we're orienting on the original ryzom file scheme. It lies in the same directory as the sheets_id.bin.

h2. Adding Armor

h3. General

Each craftable item needs a .sitem file which defines the characteristics of the item and a .sbrick file which defines the crafting plan for the item (eg which material is used). As kaetemi already stated in his [[AddArmorPartSitem|armor example]]: "Craftable items MUST be prefixed with "ic", bricks for crafting MUST be prefixed with "bc"". As we orient ourselves to the ryzom naming scheme there are some more rules to learn. But more on this in the next paragraph

h3. File Naming, Skill Families, Icons etc.

* To get correct .sitem file naming we are looking into the item_words_en.txt

* To get correct .sbrick file naming we are looking into the sbrick_words_en.txt

* We can double check with the sheets.txt if the file names are appearing there

Below is a table with some examples for the naming scheme for matis armor .sitems and there corresponding .sbricks . There is a lot more to discover if you skim through these files but this should be sufficent to get the idea.

|_.SItem| | | | | |

|=. _filename_ |=. _description_ |=. _filename_ |=. _description_ |=. _filename_ |=. _description_ |

|icmalb|item craftable matis light boots|icmamb|item craftable matis medium boots|icmahb|item craftable matis heavy boots|

|icmalv|item craftable matis light vest|icmamv|item craftable matis medium vest|icmahv|item craftable matis heavy vest|

|icmalg|item craftable matis light gloves|icmamg|item craftable matis medium gloves|icmahg|item craftable matis heavy gloves|

|icmalp|item craftable matis light pants|icmamp|item craftable matis medium pants|icmahp|item craftable matis heavy pants|

|icmals|item craftable matis light sleeves|icmams|item craftable matis medium sleeves|icmahs|item craftable matis heavy sleeves|

| | | | |icmahh|item craftable matis heavy head|

|_.SBrick| | | | | |

|=. _filename_ |=. _description_ |=. _filename_ |=. _description_ |=. _filename_ |=. _description_ |

|bcmaea01|Heavy Boots - Basic Quality|bcmaea07|Light Boots - Basic Quality|bcmaea12|Medium Boots - Basic Quality|

|bcmaea02|Heavy Gloves - Basic Quality|bcmaea08|Light Gloves - Basic Quality|bcmaea13|Medium Gloves - Basic Quality|

|bcmaea03|Heavy Helmet - Basic Quality|bcmaea09|Light Pants - Basic Quality|bcmaea14|Medium Pants - Basic Quality|

|bcmaea04|Heavy Pants - Basic Quality|bcmaea10|Light Sleeves - Basic Quality|bcmaea15|Medium Sleeves - Basic Quality|

|bcmaea05|Heavy Sleeves - Basic Quality|bcmaea11|Light Vest - Basic Quality|bcmaea16|Medium Vest - Basic Quality|

|bcmaea06|Heavy Vest - Basic Quality|||||

> *Note*: The character combination in front is equal to the FamilyId defined in each .sbrick file

For the crafting plans we need to know the corresponding skills involved

* To get the correct skill family we are looking into skill_words_en.txt

Below is a table with some example skills we are going to use and there skill family. This should give you an sufficent idea.

|=. _skill familyId_ |=. _skill description_ |=. _filename_ |=. _description_ |=. _filename_ |=. _description_ |

|SCALBEM|Master Light Boots Crafting|SCAMBEM|Master Medium Boots Crafting|SCAHBEM|Master Heavy Boots Crafting|

|SCALGEM|Master Light Gloves Crafting|SCAMGEM|Master Medium Gloves Crafting|SCAHGEM|Master Heavy Gloves Crafting|

|SCALPEM|Master Light Pants Crafting|SCAMPEM|Master Medium Pants Crafting|SCAHHEM|Master Heavy Helmet Crafting|

|SCALSEM|Master Light Sleeves Crafting|SCAMSEM|Master Medium Sleeves Crafting|SCAHPEM|Master Heavy Pants Crafting|

|SCALVEM|Master Light Vest Crafting|SCAMVEM|Master Medium Vest Crafting|SCAHSEM|Master Heavy Sleeves Crafting|

|||||SCAHVEM|Master Heavy Vest Crafting|

Throughout the existing .sbricks i found they always used the master skill, although there are familyIds for e.g. the expert skill. Im adapting this remembering that even in original ryzom they got this strange info message that you can`t gain any more XP in the master skill lvl when killing low mobs even though you not yet reached that master skill.

All items, skills and plans etc. need an icon to show ingame. Here is a short list, find others in the ryzom_assets:

|=. _icon_ |=. _description_ |=. _icon_ |=. _description_ |

|AR_botte.tga|icon for boots|BK_matis.tga|matis background|

|AR_hand.tga|icon for gloves|BK_fyros.tga|fyros background|

|AR_pantabotte.tga|icon for pants|BK_tryker.tga|tryker background|

|AR_armpad.tga|icon for sleeves|BK_zorai.tga|zorai background|

|AR_gilet.tga|icon for vest|||

|AR_helmet.tga|icon for helmet|||

h3. Creating Armor SItem

So first we are looking for some nice armor to add. For this step you need to unpack the @characters_shapes.bnp@. Now skim through the .shape files with the Nel object viewer or the new "object_viewer_qt":http://code.google.com/p/object-viewer-qt until you find a pleasing one. If you want the shape to have textures provide them from the ryzom assets. They can be found in e.g. *PathToAssets/Stuff/Matis/Agents/_textures/Actors*

!>shape.png!

As my toon is matis and female im choosing @MA_HOF_armor00_gilet.shape@ (MA = Matis; HOF = Homin Female). The male shape would be @MA_HOM_armor00_gilet.shape@

Ok so now its time to actually write the georges files.

Switch over to your leveldesign directory to the corresponding sitem armor folder. In my case this is 

@$RYZOM_HOME$/code/ryzom/client/common/data_leveldesign/leveldesign/game_element/sitem/armor/matis/light_armor@

There you'll find the already provided matis light armor boots file

@icmalb.sitem@

We are lazy and just copy this file. Now rename it according to your desired item (see filenaming above). As i want to have a matis light vest i'll name it @icmalv.sitem@

Open it and you should see something like this:

<pre><code class="CPP">

<?xml version="1.0"?>

<FORM Revision="$Revision: 1.4 $" State="modified">

  <PARENT Filename="_gma_l.sitem"/>

  <STRUCT>

    <STRUCT Name="basics">

      <ATOM Name="ItemType" Value="Light boots"/>

    </STRUCT>

    <STRUCT Name="faber">

      <ATOM Name="Tool type" Value="ArmorTool"/>

    </STRUCT>

  </STRUCT>

  <LOG/></FORM>

</code></pre>

As you can see there's also a parent defined which declares some standard matis armor values. We dont need it at the moment but if you want to have a look at it you'll find the file at @leveldesign/game_element/sitem/armor/_parent/matis@

So now we need to change the values to match a vest:

* change the "@EquipmentSlot@" from @Value="Feet"@ to @Value="Chest"@

* change the "@CraftPlan@" to "@bcmaea11.sbrick@". This is the needed corresponding sbrick file i mentioned earlier. We will create it later.

* change "@shape@" and "@shape_female@" to the shape names we found out earlier (@MA_HOM_armor00_gilet.shape@ and @MA_HOF_armor00_gilet.shape@)

* change "@icon@" to "@AR_gilet.tga@" (see icons above)

* if you like you can add another "@ATOM@" below "@icon background@" in the "@3D@" "@STRUCT@". Name it "@color@" and give it the value "@White@" (Black, Beige, Green, Red, Turquoise, Blue, Violet are also available).

* save the file which should now look something like this:

h3. Creating Armor SBrick

So far so good! Now we need to add the brick for crafting. Have a look into the sbrick folder 

* @leveldesign/game_element/sbrick@). 

There you will find the @bcmaea07.sbrick@ file which was mentioned in the .sitem file for the light boots as "CraftPlan".

Make a copy of @bcmaea07.sbrick@ and name it "bcmaea11.sbrick". It should look like this:

Again we are going to change it now to resemble a vest craft plan

* change IndexInFamily to 11 as this is the 11th item in the BCMAEA family

* change Skill to SCALVEM (Master Light Vest Crafting)

* change icon to AR_gilet.tga

* change "Crafted Item" to icmalv.sitem (the one which we created earlier)

* for simplicity i shortened the raw material list :)

h3. Make it available on server and client

!>light_armor_set.png!

Well, we have come a long way :) Now its time to test it!

* Build the sheets_id.bin with the make_sheet_id tool and copy it to the user dir in your game client dir

* Build the .packed_sheets with the sheets_packer and copy it to the same location

* Copy your newly created sheets on the server and delete all .packed_sheets from the server/data_shard and server/src/entities_game_service folders if existing

If it works, the server will recreate the .packed_sheets in server/data_shard

* Make sure the two files we created are existing in the correct dir in your leveldesign dir and that they contain the content i explained before

* Start your server

* start your client and let him connect to your server

* when ingame select your char and type the following command into the chat

> /a createItemInBag icmalv.sitem 1 25

* you should now have the new item in your inventory, congratz :D

h2. Adding Spells

!>edit_acid1.png!

As for the current system a spell consists of different components:

* The general type (heal, damage, affliction etc.)

* An effect type for that general type (e.g. cold and acid are dmg spell effects)

* The explicit spell level component (eventually while leveling you can e.g. replace your old boring acid damage spell lvl 4 with the brand new lvl 5)

* Options for the spell like area damage or ricochet

* Credits to equal the costs of the spell (common credits are Mana (SAP as with ryzom ;) ) or cast time etc.)

h3. Add cold spell

So lets start with something easy. Fortunately WinchGate provided us with an example acid spell which we will take as guideance.

So first head over to your sbrick dir.

We already have the general damage spell component which is defined in the @bmpa01.sbrick@ file but as we are going to do another damage spell, we can ignore it for now.

*Creating the cold damage spell effect*

The acid spell effect is defined in the @bmoetea01.sbrick@ file. Copy it, name it @bmoetea02.sbrick@ and open it so we can change it accordingly to the cold effect. You should see something like this:

So now we are going to add something more complex. For the heal spell we need to define a new generic spell type, the new spell effect and the actual spell level.

Switch to your sbrick folder and find the @bmpa01.sbrick@ file, copy it and rename it to @bmpa04.brick@. This file will define the new generic type for heal spells. Open it and it should look something like this:

</code></pre>

* Change the @Action Nature@ to @CURATIVE_MAGIC@ which is the coded family for heal spells. 

* If you want you can change the @MinCastTime@. The old value @28@ means it will take 2.8s to cast this spell. A value of @20@ would mean 2.0s cast time.

* Change the @Icon@ to @ICO_Celestial.tga@

* Change @IconBack@ to @MP_Back_Curative.tga@

* Change the @f0@ atom from @Mandatory@ to @BMDHTEA@ which is the heal effect family

* I did remove the @f3@ atom from @Optional@ because it is the Vampirism efecct which doesnt make sense for a heal spell; i think this was said somewhere in the source code too

*Creating the heal spell effect*

Now find the @bmoetea01.sbrick@ file, copy and rename it to @bmdhtea01.sbrick@. The content of this file which previously defined the acid spell effect will now be adjusted to define a heal hp spell effect. Open it and it should look something like this:

Time to test it!

* Build the sheets_id.bin with the make_sheet_id tool and copy it to the user dir in your game client dir

* Build the .packed_sheets with the sheets_packer and copy it to the same location

* Copy your newly created sheets on the server and delete all .packed_sheets from the server/data_shard dir if existing

* Make sure the three files we created are existing in the correct dir in your leveldesign dir and that they contain the content i explained before

* Start your server

* Start your client and let him connect to your server

* When ingame select your char and type the following command into the chat

> /a learnBrick bmpa04.sbrick

> /a learnBrick bmdhtea01.sbrick

> /a learnBrick bmdhtmp00005.sbrick

* You should now be able to create a heal spell, congratz :D

h3. Add sap credit

Ryzom Core provides a sap credit 2 defined in @bmca00002.sbrick@.

Let's create a sap credit 5.

Copy the previous file and name it @bmca00005.sbrick@.

Then open it to create the desire sap credit.

You should see something like this:

<pre><code class="CPP">

</code></pre>

!>sap_credit.png!

* Change the @IndexInFamily@ to @5@, that's the 5th credit in the family

* Change the @SabrinaCost@ to @-5@, the value of the credit

* Change the @Property 1@ to @SAP: 10@, the sap cost of the credit

Time to test it!

* Build the sheets_id.bin with make_sheet_id, copy it to your client user folder

* Build the .packed_sheets with sheets_packer, copy everything in the same folder

* Copy your newly created sheets on the server and delete all .packed_sheets from code/ryzom/server/data_shard

* Place the new brick in your server

* Start your server

* Connect your client to your server

* Type the following command in your client

> /a learnBrick bmca00005.sbrick

* You should have a new sap credit available now.

h3. Add bomb effect

The bomb effect allows us to hit multiple targets.

Let's create our own file this time.

We will use an existing sheet name.

Create a new file and name it @bmof00040.sbrick@.

Then paste the following content:

<pre><code class="CPP">

<?xml version="1.0"?>

<FORM Revision="$Revision: 1.0 $" State="modified">

  <STRUCT>

    <STRUCT Name="Basics">

      <ATOM Name="FamilyId" Value="BMOF"/>

      <ATOM Name="IndexInFamily" Value="1"/>

      <ATOM Name="SabrinaCost" Value="0"/>

      <ATOM Name="SPCost" Value="7"/>

      <ATOM Name="Property 0" Value="AREA_BOMB: 20: 0.9: 5"/>

      <ATOM Name="Property 1" Value="AREA_TARGETS: 0.9: 5"/>

      <ATOM Name="LearnRequiresOneOfSkills" Value="SM 0"/>

      <ATOM Name="Action Nature" Value="UNKNOWN"/>

    </STRUCT>

    <STRUCT Name="Client">

      <ATOM Name="Icon" Value="ICO_Bomb.tga"/>

      <ATOM Name="IconBack" Value="OP_Back.tga"/>

    </STRUCT>

  </STRUCT>

</FORM>

</code></pre>

!>bomb_effect.png!

Let's try to understand the syntax.

* Set the @FamilyId@ to @BMOF@, that's the base name of the sheet family

* Set the @IndexInFamily@ to @1@, it's the 1st effect in the family

* Set the @SabrinaCost@ to @0@,

we are setting the sap cost of the effect to @0@, that way we don't need more sap credits

* Set the @Property 0@ to @AREA_BOMB: 20: 0.9: 5@,

the syntax @AREA_BOMB: Radius: MinFactor: MaxTargets@

* Set the @Property 1@ to @AREA_TARGETS: 0.9: 5@,

the syntax @AREA_TARGETS: TargetFactor: MaxTargets@

* Set the @Action Nature@ to @UNKNOWN@,

the bomb effect can be use with both the acid spell and the healing spell

* Set the @Icon@ to @ICO_Bomb.tga@, the foreground icon

* Set the @IconBack@ to @OP_Back.tga@, the background icon

!>bomb_effect2.png!

Time to test it!

* Build the sheets_id.bin with make_sheet_id,

copy it to your client user folder

* Build the .packed_sheets with sheets_packer,

copy everything in the same folder

* Copy your newly created sheets on the server and delete all .packed_sheets from

code/ryzom/server/data_shard

* Place the new brick in your server

* Start your server

* Connect your client to your server

* Type the following command in your client

> /a learnBrick bmof00040.sbrick

* You should have a bomb effect available now.

h3. Add removal brick

We need a brick to remove the stanzas in our actions.

We will create a dummy brick for that purpose.

Create a new file and name it @big_remove.sbrick@.

Then paste the following content:

<pre><code class="CPP">

<?xml version="1.0"?>

<FORM Revision="$Revision: 1.0 $" State="modified">

  <STRUCT>

    <STRUCT Name="Client">

      <ATOM Name="Icon" Value="No_Action.tga"/>

    </STRUCT>

  </STRUCT>

</FORM>

</code></pre>

!>removal_brick.png!

* Set the @Icon@ to @No_Action.tga@, the icon of our dummy brick

Time to test it!

* Build the sheets_id.bin with make_sheet_id,

copy it to your client user folder

* Build the .packed_sheets with sheets_packer,

copy everything in the same folder

* Copy your newly created sheets on the server and delete all .packed_sheets from

code/ryzom/server/data_shard

* Place the new brick in your server

* Start your server

* Connect your client to your server

* Type the following command in your client

> /a learnBrick big_remove.sbrick

* Now you've got a removal brick.

h3. Making spells visible in skill tree & on trainers (todo)

Todo

h2. Troubleshooting

If not everything is working as expected enable debug infos for the EGS service on your server. Set the following parameters in EGS. Now when trying to create a armor or learn some bricks you should get some more infos in the EGS output to find the error. Of course you can also ask me in irc.

* EGS commands

** VerboseBrickManagerInfo 1

** VerboseBrickManagerDbg 1

** DisableNLDebug 0
