Hi,
Can anyone show me how to detect contact between BoxCollier2Ds without RigidBody at cc version 3.6? I have tried docs, used RigidBody but i have many objects that cause reducing FPS.
…
Many thanks,

@Koei idk why in cocos-test-projects

PhysicsSystem2D.instance.on(Contact2DType.BEGIN_CONTACT, this.onBeginContact, this);

can works,I just simply copy but nothing happen, I create node with collider exactly like cocos-test-projects, I try with cc 3.5.1,3.6.0,3.6.2
