How often is OnCollisionEnter called?
Those multiple GameObject’s are the two GameObject’s that are colliding with one another. When they collide, OnCollisionEnter is called multiple times. 2. Your script with the OnCollisionEnter function is attached to the-same GameObject multiple times.
What is ontriggerenter2d?
OnTriggerEnter – Is called whenever an object with a collider has passed through an object with an “isTrigger” checked collider. For example, if you were to make a box trigger and the player walked through it, that would fire the OnTriggerEnter method on that object.
Why is the oncollisionenter not working in Unity?
While the OnCollision methods receive a Collision object with more information about how the collision occured, the OnTrigger methods only receive the Collider component which triggered it. Further, take note of the collision action matrix in the documentation.
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).
Is there a way to ignore collisions with physics?
You can ignore collisions with Physics.IgnoreCollision or Physics.IgnoreLayerCollision . If you set the other collider to be a trigger only, it should work, if I understand your issue correctly. That is what the isTrigger is for.
What happens when a collision between two colliders occurs?
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.
