Collider just for Tag (2D) (C#)

Questions & Answers
1

This is aggain a pretty basic Question I guess, but I can’t figure out how to do this:

I want to use a 2D Boxcollider to check for collision with a tag with

  void OnCollisionEnter2D (Collision2D something) {
  if (something.collider.tag == "someTag")
  //do something
  }

But I dont want my Objects to actually collide.
So basically what I want is to check if my player is at a certain position (not via transform or something like that), but I want to be able to walk past or through that collider…

Any Tips?

Thanks

It sounds like you want a Trigger.

Here is a 1 that covers the trigger concept using the standard (3D) physics system as an example.

You will find they work pretty much the same over in the 2D space, but be aware that you will need to use the 2D suffix e.g. OnTriggerEnter2D()
