[quote="newt":2zvqn9ea]Couldn't you get a dummy hit box to do that for you?
Like if sprite angle = 45 dummy set frame to frame 2, or for something a little more accurate, you could set up the dummy to set its height and width via multiple image points from the host sprite.
dummy set height to distance(imagepointX("top"),imagepointY("top"),imagepointX("bottom",imagepointX("bottom"))...?
Ok dunno if that will work haven't tested it.[/quote:2zvqn9ea]
What do you mean by dummy hit box? The whole point of this is for the box collision mask to rotate with the sprite, so there aren't huge corners of nothingness that can trigger collisions in rectangular-ish rotated objects. A dummy hitbox would use an extra object, and would have to use per pixel collisions anyways, since it's the only type of collision mode that works with rotated sprites. The whole point is so you can better benefit from the performance savings of box collision mode.
