How to change collision detection modes in Unity.Īrticle continues after the advertisement: Get a virtual business domain email Again, the idea here is to set the collision detection mode to Continuous for fast-moving objects, and leave the rest of the objects at the default value of Discrete. In Unity, the option to turn on continuous collision detection can be found on the Rigidbody2D and Rigidbody components, which are used in 2D and 3D games respectively to give objects physics-based movement. This is for a simple reason: continuous collision detection is significantly more expensive, so having too many objects using it can unnecessarily use up computing power! Since only fast-moving objects suffer from the tunnelling problem, developers often enable continuous collision detection only for these objects. Continuous collisionĪlthough continuous collision detection is clearly the better choice, game engines generally do not enable continuous collision detection for all objects in their physics engines. This method of detecting collisions is called continuous collision detection, whereas the one that doesn’t prevent tunnelling is called discrete collision detection.
