Types

typedef struct ilG_trackiterator ilG_trackiterator;

A type used for iterating over all of the tracked positionables in a context.

Functions

void ilG_trackPositionable(ilG_context*, il_positionable*);
void ilG_untrackPositionable(ilG_context*, il_positionable*);

Registers a positionable to be tracked (AKA drawn) in the provided context. WARNING: the drawable, material, and texture in the positionable MUST have an ID assigned (see the *assignId functions) or they will not be registered.

ilG_trackiterator* ilG_trackiterator_new(ilG_context*);

Creates a new iterator for the given context.

int ilG_trackIterate(ilG_trackiterator*);

Iterates by 1 step and returns whether it was successful.

il_positionable* ilG_trackGetPositionable(ilG_trackiterator*);
ilG_drawable3d* ilG_trackGetDrawable(ilG_trackiterator*);
ilG_material* ilG_trackGetMaterial(ilG_trackiterator*);
ilG_texture* ilG_trackGetTexture(ilG_trackiterator*);

Gets the curren positionable/drawable/material/texture from the provided iterator.
