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).

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.

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?

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.

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?

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!

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.

this looks like its been done with graphic editing software and then imported the track as an JPEG or PNG and then with the editor added the different collisions like the PolygonCollider2D component, which allows you to make curved colliders. Sounds like you need more than just the editor.
