The bullets are spheres with a sphere collider and a rigidbody attached. Here’s the code I have on the I have looked through the reference, tutorials, forums, and ask Unity, but can’t find this simple question asked. Turns out collision detection can’t happen if timescale is set to 0. But it just keeps going? using UnityEngine; using System. To help I have 2 spheres with sphere colliders (istrigger is off) controlled by VR controllers, with the root gameobject having a rigidbody on continuous dynamic and isKinematic off, and a my player object is passing through box collider. Hellclaw2099 January 19, 2023, 12:43pm 1. I’m trying to get it to detect whether it touching a certain game object and if its not to The fix is to either lower the fixed timestep (so physics are calculated more frequently, at the cost of performance), change the collision mode to dynamic or one of the others (has other issues that may not work for all situations), slow So I have this script on 2 objects void OnCollisionEnter(Collision collision) { Debug.

You would assign obj-tagged objects to a particular layer, and the object in your post now i got the same problemi have group of cloud particles where each cloud is separated with some distance. (In theory, a trigger is less work for the engine than a full collision, when Unity will call the method automatically if a collision is detected. I think it’s the problem, and you are also comparing with game object name, and you should use tags instead. Tudman May 24, 2024, 2:54pm 1.
