Does OnCollisionEnter need collider?
In contrast to OnTriggerEnter, OnCollisionEnter is passed the Collision class and not a Collider. The Collision class contains information about contact points, impact velocity etc.
What is OnCollisionEnter unity?
OnCollisionEnter is an event: Unity calls it when the object (which must have a Rigidbody) collides with any collider. This event may occur in both objects, the rigidbody and the hit object.
Why is C # oncollisionenter not working in Unity3D?
(c) One of the objects (doesn’t matter which of them) is a rigid, non kinematic & non static object (the second don’t have to be a rigid body). (d) Due to computational difficulties MeshCollider might have hard times colliding with other mesh collider, use them with caution.
Why is the collider not working in Unity?
You may also need to set the new collider to isKinematic, though I don’t see that changing the way the collider works, just to stop it from being processed by PhysX. Another possible issue: The order of Rigidbody and Collider components on the game object.
How to call oncollisionenter on trigger Collider?
If you want your OnCollisionEnter to be called make sure: (a) Both objects have a collider attached. (b) None of the objects is a trigger collider (this will issue OnTrigger function & not OnCollisionEnter) (c) One of the objects (doesn’t matter which of them) is a rigid, non kinematic & non static object (the second don’t have to be a rigid body).
When do collision messages go out in Unity?
Taken from the Unity docs: When a collision between two Colliders occurs and if at least one of them has a Rigidbody attached, three collision messages are sent out to the objects attached to them. These events can be handled in scripting, and allow you to create unique behaviors with or without making use of the built-in NVIDIA PhysX engine.
