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.

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!

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 ) {.

Looking at your question it should be, just collision detection to make the object stop, no need to generate physics effects. What version of Creator editor are you using?

I’m mainly of the idea that if something works, doesn’t mean it’s the best approach. I am using that currently, but I would have been happier understanding why I can’t use the other approach.

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.

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?

And the way to do that is by altering the collision mask on our block. Now, we haven’t talked about collision masks yet, so let’s do a quick overview of them and we’re going to dive way deeper into them in the next module where we make our space game. You can come in here and you can change the collision mask.

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; }

Speaking at the Collision conference in Toronto on Tuesday, Radulovic-Nastic downplayed the idea that developers should be worried about their jobs because of the tech. "I I personally believe that Gen AI will be a co-pilot to our people, and has the opportunity to scale and enhance human creativity," Radulovic-Nastic said.

When dealing with rectangles, it’s actually easier to tell if there isn’t a collision than if there is. I can isolate all of the situations where a collision is impossible, check for those, and then say if any of these conditions comes back true, there’s cannot have been a collision. That’s [ contrapositive ] logic for you!

How many collision checks do you need to make here to see if Zangief gets hit? Now here’s a question - how many collision checks do I need to make in order to tell if Ryu hit Gief this frame? With thousands of polygons potentially colliding, that can easily mean millions of collision checks every frame. If yes, Zangief gets hit.

Seems like we could grab those coordinates and then create an object at those coordinates to trigger collision with a 2dcollider component and have the collision trigger the function our button normally would? do we not have the ability to get the mouse position coordinates on mouse click without raycasting?

also, it probably wouldn’t be a good solution for someone making a game that uses a bunch of collision objects as clicking on a collidable object would cause it to trigger.
