OOOOOOOOO_OOOOOOOOO! I didnt realize that. Thx. Ima restructure my code and see wat happens... I really appreciate the help.

I have found the problem. When I set image_index back to 0 before I change the image_index, it seems to work fine. No more miscalculations with the place_meeting. I do not know why, but it seems to fix this. I put:

image_index = 0;
Then the script to align the objects.

Thank you for helping, I really appreciate it.

Well, thanks for helping, but the problem isnt the xx and yy, because that variable only changed in that script. Other than that it is used to draw_sprite.

I solved the problem, by using an alternative way, by drawing each sprite in a different direction, got that idea from you when you answered my other question
Therefore image_angle will not change at all. If anyone else knows why this happens I would still like to find out why.

To just put further clarification, the script above is in a press key event(spacebar). Then left press(another key event) to create the object in room on a 16*16 grid.
When you press the key(spacebar), obj_control uses:

with(obj_cell) {update the angle and image}.

Then the obj_cell do:
draw_sprite_ext(sprite_index,image_index,x+xx,y+yy,1,1,image_angle,image_blend,1);

That is the only scripts in the game. I hope that better helps.

So...is there no way to rotate the mask for one instance? Like directly?

Well, what I was hinting at, is if your sprite is 48*48, and you rotate it, it could possible hit itself while checking for collision at +/- 24 pixels? But I see you included something to handle that.

I don't think your problem lies in this piece of code. Is it possible that you're not adjusting your x and y correctly with your xx, and yy?

...What do you mean by adjusting? If you mean adding it to x and y:

The object has a draw_sprite function drawing it with x+xx and y+yy. the sprite is 32*32 with the origin centered.

I cant have x += xx because if you do that multiple times, itll move.

Hope that helps.
