Question by Wrobb · Feb 16, 2021 at 01:22 PM · collisiontriggerphysics2dcollider2d

Physics2D.OverlapCircle dont detect triggers

I want to use this small script to find all objects with a certain tag in a certain radius. The problem is that the objects I am looking for have istrigger activated in the collider and therefore they are not detected. How can I solve this?

     private void Bash()
     {
         Collider2D[] colls = Physics2D.OverlapCircleAll(transform.position, BashRadius);
         
         foreach (Collider2D coll in colls)
         {
             if (coll.tag == "boom")
             {
                 //Do something
             }
         }
         
     }

right before if (coll.tag == "boom") put Debug.Log(coll.tag); then you will see how it is working.

Might be worth checking if your project settings > physics 2d has "queries hit triggers" ticked

Them having isTrigger activated or not should not matter at all, they are colliders and should be found by OverlapCircle. Your tag is likely wrong, remember that tags are case-sensitive. Also use CompareTag()

Thanks for the quick reply. I tried it with compareTag and it still doesn't work. Even if I remove the tag request, the object is not detected.

Check if it is in radius, did you do the Debug.Log() advice that @logicandchaos gave you in the comment on your answer? That should give you all the info you need. Is your tag "dog" or "Dog"?

Yes, I have tried, but nothing is displayed in the console.

I just tried everything in a new Unity Project and everything works. No idea what the problem is but thanks for the suggestions.
