I encountered a problem where i am not getting Collision callbacks in my code. After making these changes i am still not getting any collision callbacks. In the process of migrating my cocos creator 2.4 project to cocos creator 3.7, Can you guys please help with what could be the reason that callbacks are not getting triggered?

I made a two-layer tiled map and one of the layers has a collision property. how can I check the collision between the player and the layer containing the collision property

How can i intercept and calculate the collision from a static and a kinematic body? oh that one, yes. I have my elements. But what i don’t know how to work is on the callbacks.

Let me head straight forward to an answer: don’t use the builtin physics engine or the collision system in Cocos, try GitHub - Sinova/Collisions: Collision detection for circles, polygons, and points if you want to have an in depth understanding of the topic. Hi there, this question is very interesting, it’s basic but not easy.

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?

The character controller physics of the Quake 3 Arena game engine are responsible for handling the movement and collision detection of the player character. These physics are designed to simulate the movement of a first-person shooter (FPS) character in a 3D environment, and are based on a combination of kinematic and dynamic physics.

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; }

It can be handled like this. added object points in TieldMap, adding properties to the object points. preparing the prefabricated body in advance in cocos. reading the coordinates and type information of the object point after loading the map and creating the prefabricated body dynamically.

hi, thanks for the response, but i was searching about a 2d context, not 3d. The version of Cocos Creator is 3.6.3. For now what i found is the worldManifold method that i have to call with the contact Object. But i don’t know how to manage it, there is some example or article ?

I’ve not installed already a module inside a cocos creator project. Do you mean to install it with npm and use it within a script component? If yes, can you show me an example how to do it? This is a first attempt to use a module inside cocos creator, i’m not already 100% confident with it but i would like to try it!

Using that approach, I was wondering if you need the non-physics collision system to make rect and containsPoint work for collisions other than just rectangle to rectangle collisions. I read the forum post about not using the physics engine to keep things simple.

Allows collisions against the physics world. Baked SDF Collision. Still, for complex interiors, creating all the collisions with boxes and spheres can be a hassle. This allows approximate complex collisions with geometry (without having to test the actual geometry, which is expensive). Less flexible. Particles in Godot 4.0

If you want to set a collision with a circle you should implement it your self( but I might be wrong). rudiHammad: rectangle with rectangle. That’s good to know, thanks. I’ll be using the physics engine then.

About your physics performans maybe ur two collision alwasy colliding. I think when u recycled the node u can disable that node. In my nodePool, i alwasy open node when i wanted to use it, otherwise keep it disable. If this is the case, you may experience performance loss.
