Well, OnCollisionEnter2D (with parameter Collision2D) is one such method. It's a method that is fired (called) by Unity whenever it detects a collision between the object to which this script is attached to, and any another gameObject. Note the Collision2D col parameter we provided. And thank you for taking the time to help us improve the quality of Unity Documentation. Your name Your email Suggestion. Visual studio code swagger. Submit suggestion. Other: The Collision2D data associated with this collision. Sent when an incoming collider makes contact with this object's collider (2D physics only).
They both look similar and behave similarly, what's then the difference between OnTriggerEnter and OnCollisionEnter? The key to understand this is in knowing what are triggers in Unity.
In Unity, an object might be controlled by the physics engine or by script. If you need to control an object by script but still would like to know if an object touched another, a 'collision' happened, you need to use triggers.
Collision is under quotes because, strictly under Unity's terminology, a collision only happens when object's movements are governed by the physics engine, for the other cases what we have are simply objects touching each other, also, for such event, our script can be alerted as well.
What are triggers
A trigger is a collider that's not influenced by the physics engine. It doesn't respond to forces nor gravity. But they still do have a use for the physics engine, they are used to detect whether an object passed through another. Triggers are everywhere in Unity game development, and in other engines too to be honest.
This Reaper is controlled by a simple back-and-forth walk AI, the physics engine is not used, but we still want to know when it has touched some things in the stage. Visual studio plug in. For that, we can use an OnTriggerEnter
Collisions
A collision is also the result of an object touching another one, but instead of passing through, these objects push each other in a realistic way. Use OnCollisionEnter Anydesk smart tv. when your rigidbody colliders aren't triggers and you'd like to know when they touched each other.
Unity Oncollisionenter Not Working
For more information on how to create and use triggers, please see the official documentation on the subject. If you followed the documentation and something with your collision detection is not working, you may try to fix it using our comprehensive collision fixing tutorial.

Unity On Collision Enter Not Working
Use triggers if you don't want/need the physics engine to control your object but still need to know if an object passed through another or reached some `zone` within the game. In that case, you'll use OnTriggerEnter().

Unity Oncollisionenter Not Firing
If your object is indeed controlled by the physics engine, you'll use OnCollisionEnter() to know if an object touched another one.
