Homing missiles

I've now moved onto homing missiles. Once activated they simply 'home' in onto the mouse pointer. This was created for test purposes, but it might be the case that it stays in the game. I like the idea of a laser guided missile, allowing the player to guide the missile with the mouse pointer. Might be fun, if a little difficult to control.

I set the direction of the missile using the following code. It's crude but it works.

if instance_exists(mouse_pointer)
{
dir = point_direction(x,y,(instance_nearest(x,y,mouse_pointer)).x, (instance_nearest(x,y,mouse_pointer).y)-20)
}
