Level, Saved Object, Prefab - These have more confusing schemas, to the point where I'm not entirely sure they're distinct types from one another, and I haven't nailed them down yet -merlyn

Actor XML

This is the top-level XML file for an NPC or combat character. It binds a Character XML file to an AI angelscript file.
When a level references a character, this is the file type that is referenced.

Actor XML Example

<?xml version="1.0" ?>
<Actor>
    <Character>Data/Characters/rabbot.xml</Character>
    <ControlScript>enemycontrol.as</ControlScript>
</Actor>

Actor XML -> Character element

<Actor>
    <Character>Data/Characters/rabbot.xml</Character>
    ...
</Actor>

Required - String value. Path to Character XML

Actor XML -> ControlScript element

<Actor>
    ...
    <ControlScript>enemycontrol.as</ControlScript>
</Actor>

Required - String value. Path to AI angelscript. Relative to Data/Scripts folder

Hotspot XML

This is the top-level XML file for a hotspot game object. It specifies the billboard image, and the Hotspot angelscript file.
When a level references a hotspot, this is the file type that is referenced.

Hotspot XML Example

<?xml version="1.0" ?>
<Type>generic</Type>
<Hotspot>
    <BillboardColorMap>Data/UI/spawner/thumbs/Hotspot/empty.png</BillboardColorMap>
    <Script>hotspots/sound_hotspot.as</Script>
</Hotspot>

Hotspot XML -> Type element

<Type>generic</Type>
<Hotspot>
    ...
</Hotspot>

Required - String value. This should always have the value <Type>generic</Type>.
Note: Having two document elements is not valid XML, and I'm not sure what purpose this element serves. But leave it in, since all the hotspots do it. -merlyn

Hotspot XML -> Character element

<Hotspot>
    <BillboardColorMap>Data/UI/spawner/thumbs/Hotspot/empty.png</BillboardColorMap>
    ...
</Hotspot>

Required - String value. Path to image file. If you don't want a billboard image, you can use Data/UI/spawner/thumbs/Hotspot/empty.png.

Hotspot XML -> Script element

<Hotspot>
    ...
    <Script>hotspots/sound_hotspot.as</Script>
</Hotspot>

Required - String value. Path to Hotspot angelscript. Relative to Data/Scripts folder.

Item XML

Level Meta XML

TODO:

Material XML

This XML file specifies the sounds that will be played when a character or item interacts with a world object. It is used to model the sound differences between wood, metal, soil, ice, etc.

Data/Materials/default.xml is the global "default" material, if the material isn't specified by the world object.

When the engine or a gameplay script detects a physics event, the code will do a lookup against the current material, for an event with that event name. If the event name is found, then the corresponding sound will be triggered.

Some of these events and materials might specify modifiers (soft, heavy, etc). If they do, the code will first do the lookup against the <events mod="themod"> version of the event.
If an event with the given name is not found with that modifier, the code will then lookup a version of the same event name, but with no modifiers specified.

Some of the values, if not specified, will look at a global "base" material to find the value of the parameter. max_distance is the only one of those parameters right now.

Data/Materials/base.xml is the global "base" material.

Material XML Example

From Data/Materials/dirt.xml - this is not the complete contents of that file.

Material XML -> Physics element

<material>
    <physics hardness = "0.8" friction = "1.0" sharp_penetration = "1.0" />

</material>

Optional - Decimal value. Default: 1.0
The friction between any other object and the object this material is applied to.
In real life this would depend on the materials for both objects, but the game makes simplifying assumptions to make the mapping a bit less complicated.

Rig XML

This is the XML file for a character skeleton. It binds a Character XML file to an AI angelscript file.
When a level references a character, this is the file type that is referenced.

Rig XML Example

<?xml version="1.0" ?>
<rig bone_path = "Data/Skeletons/r_wolf2.phxbn"
     model_path = "Data/Models/Characters/IGF_Wolf/IGF_Wolf.obj"
     mass_path = "Data/Skeletons/r_lt_dog.xml"/>

Rig element -> bone_path attribute

<rig bone_path = "Data/Skeletons/r_wolf2.phxbn"/>

Required - String value. Path to the skeleton file, using the custom Phoenix Engine skeleton file type (PHXBN. This file MUST have been exported using the mesh specified in model_path.

Rig element -> model_path attribute

<rig model_path = "Data/Models/Characters/IGF_Wolf/IGF_Wolf.obj"/>

Required - String value. Path to Obj model file to use as skinned the character mesh. This file MUST be the same as the one used when exporting the skeleton specified in bone_path.

Rig element -> mass_path attribute

<rig mass_path = "Data/Skeletons/r_lt_dog.xml"/>

Optional - String value. Path to Rig XML. Used to override the current skeleton with the bone masses from a different skeleton.

Shader Preload XML

TODO:

Sound Group XML

This is the XML file that describes a group of sounds. One of those sounds will be randomly chosen and played whenever the sound group is triggered.

The file will specify a count of the number of variants that exist, and a sound file will need to exist for each of those variants.
For a Sound Group XML with three variants, the XML file and and corresponding sound variants should follow a naming scheme like this:

  • Data/Sounds/example_subdir/example_sound_group.xml
  • Data/Sounds/example_subdir/example_sound_group_1.wav
  • Data/Sounds/example_subdir/example_sound_group_2.wav
  • Data/Sounds/example_subdir/example_sound_group_3.wav

Sound Group XML Example

<?xml version="1.0" ?>
<soundgroup
    variants = "3"
    delay = "5.3"
    volume = "0.1"
    max_distance = "77.5"
/>

Sound Group element -> variants attribute

<soundgroup variants = "3" />

Optional - Integer value. Default: 1.
The count of variants. There must also be a corresponding SoundGroupXmlName_1.wav file for every variant, numbered incrementally up to the variant count.
E.g. if there was 3 variants, there would need to be files named SoundGroupXmlName_1.wav, SoundGroupXmlName_2.wav, and SoundGroupXmlName_3.wav.

Sound Group element -> delay attribute

<soundgroup delay = "5.3" />

Optional - Decimal value. Default: 0.0.
A delay to add to the start of sound playback, in seconds.

Sound Group element -> volume attribute

<soundgroup volume = "0.1" />

Optional - Decimal value. Default: 1.0.
The volume to play back the sound.
This is further multiplied by the gain specified when triggering the sound group in gameplay code.

Sound Group element -> max_distance attribute

<soundgroup max_distance = "77.5" />

Optional - Decimal value. Default: 30.0.
The maximum distance that the sound can be heard by the player.
It will be overridden by the max_distance in the collision sound event, in the Material XML, if specified for the given collision sound event.
