Hello, there is a tutorial how to work with meshes in v 2.4 https://docs.cocos.com/creator/manual/en/3d/mesh.html
How can i create a dynamic mesh in v 3.x?
I can ask engineering to have a look at this topic.
Which version of 3.x are you using?
(There may be slight differences between versions)
I am using v3.3.2.
And one more question. Does Particle System support collisions? Like this: Unity - Manual: Collision module
The particle does not currently support collider yet.
Okay thank you. What about dynamic meshes?
Someone in our Chinese forum has shared a tutorial on how to create it. You can take a look at
Or, you can check out this file that briefly describes how to create a mesh

Thank you. But this is not enough. I see that i can create a mesh dynamically. It is ok, but i don’t see how i can update vertices of a mesh.
One way that i found is create a new mesh with updated vertices and set it to a mesh renderer.
Something like this:
update(dt: number) {
const line: primitives.IGeometry = {
positions: [
math.randomRange(-1, 1), math.randomRange(-1, 1), 0, // bottom-left
math.randomRange(-1, 1), math.randomRange(-1, 1), 0, // top-left
math.randomRange(-1, 1), math.randomRange(-1, 1), 0, // top-right
math.randomRange(-1, 1), math.randomRange(-1, 1), 0, // bottom-right
],
indices: [
0, 3, 1,
3, 2, 1,
]
};
let newMesh = utils.createMesh(line)
this.node.getComponent(MeshRenderer)!.mesh = newMesh
}
Is it ok? Or maybe mesh class has a method to update it?
