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.

Parameters

	startX	origin x position of the ray
	startY	origin y position of the ray
	startZ	origin z position of the ray
	dirX	normalized x direction of the ray
	dirY	normalized y direction of the ray
	dirZ	normalized z direction of the ray
[out]	hitX	normalized x position of the hit
[out]	hitY	normalized y position of the hit
[out]	hitZ	normalized z position of the hit
[in,out]	hitDepth	as input, maximum length of the ray; as output, distance along the ray of the hit
[out]	hitNx	x normal direction of the hit
[out]	hitNy	y normal direction of the hit
[out]	hitNz	z normal direction of the hit

Returns

entity index or NO_COLLIDER is none is hit
