Hi, noticed something weird with the bullet behavior when I set it to BOUNCE OF SOLID. In the CAPX if I have this set OFF the bullets head for the mouse coords as I want them to, no problem. Set the bounce option to on and suddenly they're firing out in the opposite direction to the mouse position. I've tried adding +180 to the angle to counter this but it didn't work.
Closing as not a bug. You should not make the player solid. If you spawn an object inside something solid, this is an impossible situation in the real world, so you should not expect anything realistic to happen either! Try spawning the objects just outside the object, or remove the solid behavior from the player.
