I've always had this problem with making an object point at a position behind it, but I just can't figure out a way to make it work this time.
So, I've got an on rails game( moves you straight forwards while you aim the gun on a 2d plain) which has the ability to face backwards( in case you passed an enemy, you can still shoot them down before they get you). I have it set up so that object position 1 x and y = mouse position x and y -320 and -240 respectively. This makes it so that it goes to the farthest corner when your mouse is at position 0,0, and the default start position for the mouse is( obviously) 320, 240, making the default starting position for object 1 be 0,0,400.
As shown above, I have object 1 automatically Z positioned at 400, and when you press the turn around button, it goes through a fancy animation and ultimately your gun's rotation angles are 0,180, and 0, with object 1 being on a new set of commands. This command set has it's Z position be -400, it's X is -1*(mouse x - 320) and it's Y is (mouse Y - 240). It makes sure to correct the object angle so that it's pointing the right way in terms of X, but the Y the gun's always at an inverted angle. Do any of you know what the problem is? It's just using the simple "point at position in space" command, so that the gun points at the object that's at the right mouse position.
