What is discrete collision detection?

What is discrete collision detection?

Discrete collision updates the collider position once per fixed frame and detect collision between the overlapping colliders. So if the object is fast enough to pass through the other in between fixed frames, it won’t hit.

What does Collision Detection do?

Collision detection is the computational problem of detecting the intersection of two or more objects.

What is the difference between discrete and continuous collision detection?

If there are no fast-moving objects in your game, you can safely use Discrete collision detection for all your objects. For dynamic objects that are not fast-moving, use Continuous collision on them if you need them to always collide with fast-moving objects.

What is the definition of continuous collision detection?

See in Glossary to Continuous or Continuous Dynamic. For speculative CCD, set Collision Detection to Continuous Speculative.

How does continuous collision detection ( CCD ) work in Unity?

Continuous collision detection (CCD) CCD ensures that fast-moving bodies collide with objects instead of passing, or tunnelling, through those objects. Unity provides the following CCD methods: To use sweep-based CCD, select a RigidBody A component that allows a GameObject to be affected by simulated gravity and other forces. More info.

Is there a fork to continuous collision detection?

Fork of code from “Efficient Geometrically Exact Continuous Collision Detection” and “Fast and Exact Continuous Collision Detection with Bernstein Sign Classification” Wrappers for various continuous collision detection algorithms.

How does speculative collision detection ( CCD ) algorithm work?

Speculative CCD works by increasing an object’s broad-phase axis-aligned minimum bounding box (AABB), based on the object’s linear and angular motion. The algorithm is speculative because it picks all potential contacts during the next physics step.
