There is no CollisionMesh in examples

[CrossroadInTheVoid]

There is no CollisionMesh in examples and it works totally unclean.

It worked like this in the past:

collision = require("3DreamEngine/collision");
...
self.box_collider_mesh = dream:loadObject("models/collider_box", {splitMaterials = false, noCleanup = true});
...
local _collider = collision:newMesh(self.box_collider_mesh);
...
_collider:moveTo (vec3(_vector_a.x, 0, -1 * _vector_a.y)); --or any other action with created collider

But as I see it was changed. What should be included to fix

attempt to index global 'CollisionMesh' (a nil value)

error? What parametres should I use?
CollisionMesh:newCollisionMesh(mesh, shapeMode)
What the mesh is? Loaded mesh object? Or a string path to an obj file? Link at documentation looks dead.

P. S. I'm thisnickwasfree, I've lost access to that acc so I've created new one.

Welcome back!

The physics has been extracted into its own extension: https://3dreamengine.github.io/3DreamEngine/docu/extensions/physics

Specifically this is how to create a shape (the prepared collision mesh) and world:add (which then creates an collider)

--create a shape from this object and it's current transformation
local shape = physics:newObject(object)

--add this shape to the world
local collider = world:add(shape, "dynamic", x, y, z)

Thanks. But:
Error: extensions/physics/world.lua:261: attempt to index field 'physics' (a nil value)
Where is the creation of love.physics table?

[Luke100000]

Either in the conf.lua https://love2d.org/wiki/Config_Files or you can require it manually love.physics = require("love.physics")

[CrossroadInTheVoid]

Oh, it was switched off in config. Thank you. And sorry for disturbing, take my questions as «dumb user test» for your project.

And some more questions.
Method moveTo removed. So, how to move collider to vec3 coordinates? I guess applyForce or applyLinearImpulse are not the best way.
I've used colliders to detect mouseclicks at mobs and raycasts between mobs. Looks like it's not good choice for such a thing now and I should use RaytraceMesh?

[Luke100000]

Yes, use raytracing for that. The physics extension is 2.5D and is based on Box2d. Setting position is an oversight from me, will add that, but it boils down to collider:getBody():setPosition(x, z) and collider.y = y where body is a love2d physics body.
