Question by NivekJump · Jan 09, 2015 at 04:29 PM · c#cameramoveobjectsoverlap

Moving two objects and avoiding overlap with each other

Hi Guys Im Moving two objects with this function:

 void OnMouseDrag(){
             float mouseX = Input.mousePosition.x;
             float mouseY = Input.mousePosition.y;
             Vector3 newPosition = Camera.main.ScreenToWorldPoint(new Vector3(mouseX, mouseY, 99));
             this.transform.position = newPosition;
 }

How can i avoid the objects to overlap with each other? Thanks.

do you mean you want things to collide whilst dragging? try here. I haven't tested this script but its by top man @Eric5h5 so I'm going to assume it works perfectly ^^.

If you mean you want them to overlap and then when you stop dragging they should separate, then on mouse up you should check for overlaps and move things away from each other, there are lots of algorithms around for that sort of thing.

Hi $$anonymous$$an, thanks, but the script by Eric5h5 isnt what i want, yeah it cant drag objects, but isnt collide between objects, i want to collide, because they cant be overlap with other objects. I will try the $$anonymous$$ouseUp Thing, ill tell you it goes.

If you don't want objects to collide with each other then you can put them in different layers and define to ignore the collisions in Project Settings > Physics2D

This can also be done via script.

I don't think I understand your problem then, can you rephrase it?
