Common Script External Code

This is a list of the external code that is available inside all scripts - variables, functions, and classes that "magically" exist.

To see a list of external code that is available only in specific scripts, please see the corresponding page:

• Level Script External Code
• Hotspot Script External Code (hotspots share level script code - read carefully to see what code doesn't apply!)
• Character Script External Code
• Editor Camera Script External Code

Note: The editor camera script cannot use some of the data and functions defined below - read this page carefully to see what code doesn't apply!

This list is pulled from the ~/Documents/Wolfire/Overgrowth/ directory, from the aschar_docs.h and aslevel_docs.h files, which are automatically generated by the game.

See this page to find the location for the Wolfire/Overgrowth folder on each OS - How to clear the game's cache

TODO: Finish documenting the rest of the classes, and lists of related global functions

TODO: It's possible some of these might not work in hotspot scripts. If you find that to be the case, please copy a function to level scripts/character scripts and remove it from here.

TODO: Missing TokenIterator definition - note, cannot be used from the editor camera script, but can from level scripts, movement object scripts, hotspot scripts

Global Variables

Constants

Types in this section that specify the base type for the enum aren't actually exposed via enums. They are defined as const instances of the base type.

Functions that take those parameters will take the base type instead. E.g. _delete_on_draw is actually defined in your script as an "const int _delete_on_draw".

enum AttachmentType {
    _at_attachment,
    _at_grip,
    _at_sheathe,
    _at_unspecified,
};

enum CameraFlags {
    kEditorCamera,
    kPreviewCamera,
};

DebugDrawLifespanType enum

enum DebugDrawLifespanType : int {
    _delete_on_draw,
    _delete_on_update,
    _fade,
    _persistent,
};

Used for specifying how long a debug draw object that you create should stick around. Usually the last argument to one of those calls.

Different lifespans are useful for different scenarios:

• _delete_on_draw - The engine will automatically delete this debug draw object the next time Draw gets called. Recommended if your debug draw object gets created every time inside a Draw function, e.g. DrawGui. You might choose to use this instead of _delete_on_update so you can get smooth per-frame interpolation of the positions for the line you are drawing.

• _delete_on_update - The engine will automatically delete this debug draw object the next time Update gets called. Recommended if your debug draw object gets created every time inside Update. You might choose to use this instead of _delete_on_draw inside an enemy character script so you have less code running less frequently (since update is called at 30hz for enemy control scripts).

• _fade - The engine will automatically delete this debug draw object after a few frames, and make it fade out. Recommended if your debug draw object is triggered sporadically, rather than every frame or every update, and you want the results to stick around on screen for a few updates/frames.

• _persistent - The engine will automatically delete this debug draw object when you leave the level. This tells the engine that you would prefer to delete this object manually. If you use this value, then make sure to hold onto the return value from the call to DebugDraw*. Recommended if you want to draw a line that shows up while in-game, isn't moving around a lot (unless you're using the editor to move the object), and isn't conditional. If the display should be conditional, or the line is expected to move around quite frequently (every update or every frame), then one of the other values might make more sense, unless you're trying to conserve CPU time in your Update or Draw* function.

Debug Functions

These functions allow you to create artifacts to help you debug scripts and game beahvior.

With them you can write to the logfile, print to the debug window, draw in-game (and/or in-editor) 3D objects, do basic profiling of scripts, and get build information.

void AddDebugDrawRibbonPoint(int which, vec3 pos, vec4 color, float width);

void Breakpoint(int);

DebugDrawBillboard function

int DebugDrawBillboard(const string &in path, vec3 center, float scale, vec4 color, DebugDrawLifespanType lifespan);

Draw an image that exists in the 3D world space (as opposed to being a 2D HUD overlay image). This image is rotated to face the camera, and will scale when you get closer to it (since it lives in 3D).

The return value is an id that you can pass to DebugDrawRemove to delete the object at a future time.

• path - The path to the file that contains this image. Should be specified relative to the game install directory (e.g. Data/Textures/ui/stealth_debug/exclamation.tga)

• center - The origin of the billboard image in 3D space. The center of the image will sit on this point.

• scale - The relative size of the image. Set to 1.0 to start with, and change it from there if need be. WARNING: The scale parameter might not do anything right now. (TODO: Verify, and remove this warning if you find out that the scale parameter actually does work, or remove this todo if it doesn't work)

• color - The RGBA tint you want to apply to the object. You can use this to make the object transparent if you set the value to vec4(1.0, 1.0, 1.0, alpha_value_between_0_and_1).

• lifespan - How long you would like this billboard to stick around before it automatically gets deleted by the engine. See DebugDrawLifespanType for the values you can pass here.
  Note that you can't move billboards around, so you might need to set a lifetime lower that _persistent, and call draw repeatedly, depending on how often you expect your object to move.

int DebugDrawCircle(mat4 transform, vec4 color, DebugDrawLifespanType lifespan);

DebugDrawLine function

int DebugDrawLine(vec3 start, vec3 end, vec3 color, DebugDrawLifespanType lifespan);

Draw a line that exists in the 3D world space (as opposed to being a 2D HUD overlay line). This line will be opaque, and will only have a single color over the entire span of the line.

The return value is an id that you can pass to DebugDrawRemove to delete the object at a future time.

• start - The point in 3D space of the beginning of the line. The line will begin at this point. (If you're confused about start/end, then don't worry about it. There isn't really a distinction between the two points).

• end - The point in 3D space of the end of the line. The line will end at this point. (If you're confused about start/end, then don't worry about it. There isn't really a distinction between the two points).

• color - The color to draw the entire line. This will be an opaque color. If you want to draw a line that has transparency, see the DebugDrawLine overload that supports transparency.

• lifespan - How long you would like this line to stick around before it automatically gets deleted by the engine. See DebugDrawLifespanType for the values you can pass here.
  Note that you can't move lines around, so you might need to set a lifetime lower that _persistent, and call draw repeatedly, depending on how often you expect your object to move.

int DebugDrawLine(vec3 start, vec3 end, vec3 start_color, vec3 end_color, DebugDrawLifespanType lifespan);

int DebugDrawRibbon(vec3 start, vec3 end, vec4 start_color, vec4 end_color, float start_width, float end_width, DebugDrawLifespanType lifespan);
