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.

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).

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.

I’m trying to handle the collision of two sprites, i added BoxCollider2D to the sprites. One sprite can jump (changing the y coordinate through animation), named "character ", the other is a static object, named “key”. code for the "character ". start () {. this.collider = this.node.getComponent(BoxCollider2D); if( this.collider ) {.

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.

Yes, this behavior is expected and is consistent with how physics engines typically handle collision events. Static rigid bodies are objects that do not move and are not affected by forces or collisions. Dynamic rigid bodies are objects that can move and are affected by forces, gravity, and collisions.

best way to debug this kind of bugs is to activate physic debugging, add this to your code. onLoad() { PhysicsSystem2D.instance.debugDrawFlags = EPhysics2DDrawFlags.Aabb | EPhysics2DDrawFlags.Pair | EPhysics2DDrawFlags.CenterOfMass | EPhysics2DDrawFlags.Joint | EPhysics2DDrawFlags.Shape; }

I want to calculate how hard an object hits another object. for example, if a rock was lightly thrown at glass wall, it wont break through. But if its thrown with more force, it’ll break through easily. Is this achieved by just calculating the velocity or is there more to it?
