entity_raycast_down
s32 entity_raycast_down(f32*, f32*, f32*, f32*, f32*, f32*) source
Mostly used for shadows
get_map_IDs_by_name_checked
void get_map_IDs_by_name_checked( const char* mapName, s16* areaID, s16* mapID ) source
Same as \ref get_map_IDs_by_name, but will panic if the map doesn't exist.
test_ray_entities
s32 test_ray_entities( f32 startX, f32 startY, f32 startZ, f32 dirX, f32 dirY, f32 dirZ, f32* hitX, f32* hitY, f32* hitZ, f32* hitDepth, f32* hitNx, f32* hitNy, f32* hitNz ) source
Test a general ray from a given starting position and direction against all entities. If one is hit, returns the position and normal of the hit and the length along the ray on the output params. All output params are invalid when a value of NO_COLLIDER is returned. @param startX origin x position of the ray @param startY origin y position of the ray @param startZ origin z position of the ray @param dirX normalized x direction of the ray @param dirY normalized y direction of the ray @param dirZ normalized z direction of the ray @param[out] hitX normalized x position of the hit @param[out] hitY normalized y position of the hit @param[out] hitZ normalized z position of the hit @param[in,out] hitDepth as input, maximum length of the ray; as output, distance along the ray of the hit @param[out] hitNx x normal direction of the hit @param[out] hitNy y normal direction of the hit @param[out] hitNz z normal direction of the hit @returns entity index or NO_COLLIDER is none is hit
