GetObsPixel

Verifies that an obstruction pixel is at the given coordinates. If there is an obstruction it returns true (i.e. not zero). Otherwise, it returns false (i.e. 0). This is useful for collision detection in large in advanced game systems.

Note: Coordinates are in terms of absolute pixels on the map, not screen-relative pixels.

// If the top-left corner of the player touches any obstruction, die.
if (GetObsPixel(entity.x[player], entity.y[player]))
{
	Exit("You died.");
}
