When it comes to implementing bullet physics in Unity, understanding how to efficiently spawn and control bullet movement, as well as handle collisions with fast-moving objects, becomes crucial. In this article, we will see, how to implement bullet physics, ensuring their smooth movement and accurate collision detection. Read more

Hi, i’m relatively new on Cocos Creator, but i hope i can help you because i’m working on collision from a while me too. At your node you need add two components, RigidBody2d (Kinematic, Static or Dynamic, depends on your needs) and a BoxCollider (Circle or whatever you need).

Destoying from scene shows all children deleted, but still childrens are visible in scene on collision : - On collision with the saw, this is happening : - onLoad() { this.animationComponent = this.node.getComponent(Animation); this.animationComponent.clips[0].name What’s happening wrong with the collision detection code?

Go to Project Settings → Physics → Collision Matrix There, you can create groups and assign which group interact/ignore with which group. Then, in your node’s collider, assign the desired group for it. I’d suggest you to please read documentation and tutorials first and read them alot. Just my two cents and enjoy coding!

B grows and is now of size 2, and is still touching A - however, this won’t trigger a new collision event. I am aware I can just listen to the collision stay event, however that seems pretty inefficient as I only need to check again after the size changes… Is there any other, more efficient way to do that?

I’ve tried changing the type (static/kinematic/animated) of the other objects, but collision detection still doesn’t work. The only time collision is detected is when I set the “Character” object’s Rigidbody2D type to. However, the “Character” object doesn’t collide with other objects that have a Rigidbody2D and a Collider2D attached.

Now I need handle collision of weapon with other collider(enemy…). I know sine cocos creator 3x we need add rigidbody2d to handle collision. I’m using cocos creator 3x. I’m making character and weapon. I have player node and weapon is a child node. And I add rigidbody2d with body type kinematic for player node and weapon node.

How are you moving the player? By using force (using physics) or by updating its position property? Refer to each type Here. Some type ignore the mass and may not work with physics. For your case, you better use “Dynamic” type and turn off allow sleep checkbox as well for both the Player and the Weapon.
