Is there a way to make OnTriggerEnter work only for the colliders marked as triggers?

Question

I've looked around, but I haven't quite found my question. I'm making a very simple game and one of the aspects of the game is pushing and pulling a box. I got that part figured out, but currently if the player stands on the box, they can pull it around. I tried fixing this by making the trigger close to the ground, but, I guess, on trigger enter works for colliders that aren't marked as triggers as well.

I feel like I'm missing something obvious. I could, probably, just put this behavior in a child object and put the trigger there. But I want to know if there's a smarter solution.

Relevant Code:

 void OnTriggerEnter2D(Collider2D other){
     if (other.tag == "Player") {
         near = true;
         //Debug.Log ("Near is:" + near);
     }
 }
 void OnTriggerExit2D(Collider2D other){
     if (other.tag == "Player") {
         near = false;
         //Debug.Log ("Near is:" + near);
     }
 }

OnTriggerEnter does only fire when a collider enters another marked as a trigger. It looks from your screenshot that you have both a trigger and a non-trigger collider on the same object. This makes a compound collider - effevely merging the bounds of the colliders into one.

To keep them separate, add the collider components to separate child objects and/or place them on separate collision layers.

$$anonymous$$y dude, my pal, my friendo. This is exactly what I was looking for. I figured that makin one a child object was the solution. Thanks for the info on compound colliders. Hadn't heard of that, but it explains so much!

If you need to make it work only with triggers, then just check if the other collider is a trigger using other.isTrigger. Problem solved. For more advanced control you will need to look into collision matrix.
