Collisiondetection of Java games

In the development of Java games, we often encounter collision detection problems. As in the tank war, the shell and tank encounter exploded; in the Guardian game, the Guardian Fire Arrows and monsters meet the Monster blood loss; In a plane game, the plane sent bullets and enemy planes met to kill enemy aircraft. These all need to implement

Differences between the collision generator and trigger in unity3d CollisionDetection

To generate a collision, you must add the Rigidbody and the collision generator to the game object. The rigid body allows the object to motion under physical influence. A collision body is a type of physical component. It must be added to a game object together with a rigid body to trigger a collision. If two rigid bod
