Why are the colliders not colliding in Unity?
However for the sole purpose of destroying objects when they enter a trigger, no physics are required, it simply needs to delete the object when entering the trigger box. Click to expand… I’ve turned on IsTrigger, yet still no collision. Also tried to switch to OnCollisonEnter, but no luck.
How to fix Unity3D collision problem with 2D?
Something else important to note is that Unity only updates input on the frame, so if you read your input during the FixedUpdate (), you may double read your input (or miss it completely). It is a good idea to read your input on the Update () cycle, and set a variable to transfer logic between the methods.
What to do when box collider does not collide?
However for the sole purpose of destroying objects when they enter a trigger, no physics are required, it simply needs to delete the object when entering the trigger box. You are using OnTriggerEnter but the box collider has IsTrigger unchecked. You could either turn on IsTrigger or use OnCollisionEnter instead.
How are 2D and 3D colliders the same?
Colliders are same type. 2D and 3D colliders don’t detect collisions with each other. At least one participant of the collision needs to have rigidbody component attached.
How to check if object is not colliding with anything?
Not per se, but there are two ways you can get the information. It’s easiest to keep an int counter, and increment it in OnCollisionEnter and decrement in OnCollisionExit. When the counter is 0, there are no collisions.
What happens when you omit a rigidbody in a collider?
When you omit a RigidBody, the calculations are actually more intense. If it’s not necessarily needed, set it to kinematic. downhilldan likes this. Add a rigid body. At least 1 of the two colliders must have a RigidBody, to generate an event. When you omit a RigidBody, the calculations are actually more intense.
