Keep falling through floor

[hot magnet]

I procedurally generate a map, this map then gets the correct mesh added at the end doing the following:

mesh.Clear();
        mesh.vertices = vertices;
        mesh.triangles = triangles;
        mesh.colors = colors;

Where the vertices, triangles, and colors are assigned during generation

The mesh looks as follows in the finished map.

Now whenever I walk I keep falling through the floor, this happens both when walking, but also after not holding any input and just falling. My walking code is this:

private void FixedUpdate()
    {
        // Calculate the movement direction based on the camera's orientation
        Vector3 forward = cameraTransform.forward;
        Vector3 right = cameraTransform.right;
        forward.y = 0f;
        right.y = 0f;
        forward.Normalize();
        right.Normalize();

        // Calculate the new position using the movement direction
        Vector3 newPosition = transform.position + (forward * moveDelta.y) + (right * moveDelta.x);
        rb.MovePosition(newPosition);
    }

    public void OnMove(InputAction.CallbackContext context)
    {
        moveDelta = context.ReadValue<Vector2>();
    }```
The ground generator has a mesh collider, and I tried it with, and without rigidbody:


The player is a simple capsule collider with a Rigidbody attached:


Collision detection is set to continuous.

It looks like there's no collision

[hot magnet]

Yes indeed, so how do I get a collision?

From my knowledge Ive set everything up there is to set up :(

[native turret]

Try your movement with a plane

See if you fall through the plane

Also check the collision matrix

[hot magnet]

It appears I do not fall through this mesh

which would be the plane you wanted me to try

[hot magnet]

what is that and how do I check it

[native turret]

Google and google

[hot magnet]

"Hey google why do I fall through one mesh but not the other"

So if the collision matrix only looks for layer that shouldnt have anything to do with this since everything is on the default layer currently anyways

yeah everything with everything by default, never changed it

[native turret]

What about the physics collision matrix

[hot magnet]

that is this one?

Now youre just playing with me

Thats all there is as collision matrix unless google is hiding something from me

Wether its this or not, its on default settings because I never thouched it

Just out of curiosity, why the heck are you that far a way from the origin? Im not surprised if that can mess up the physics too

[hot magnet]

4000 is already considered far? Thats just the size of the map currently, if you mean the y value, thats just because Ive been falling for a hot minute on the screenshot

[hot magnet]

It also happens when near the world origin tho, just tried it. ESPECIALLY when I move, but since I use physics based movement and continuous collision detection that shouldnt be too much of a difference

[hot magnet]

<@&823670121133768714> I still wasnt able to solve this :(

It improved when I used rb.AddForce() instead of rb.MovePosition, but it still happens that I fall through the floor occasionally, even with no inputs just from falling down somewhere

Something is going on with your collider

Check if you haven't accidentally set your player on the plane on OnTrigger

I do this shit multiple times accidentally myself

[hot magnet]

You can see my exact settings in my screenshots above, he is not set to "IsTrigger", also, he doesnt fall thorugh the floor 100% of times, what he would if he was :(

Depending on how big your collider is there could be a chance you are teleporting through at high enough speeds/distance

Not sure though can you show your capsule collider as scale

Definitely possible for moveposition idk why it would happen for addforce though unless you go too fast

[hot magnet]

I found it mainly happens at a speed magnitude vector of 100 and above, but I even fell through from a stand still on some occasions

[hot magnet]

I clamped the max speed to a magnitude of 20, 100 is way too fast anyways

[hot magnet]

small white dot is thecapsule, it is 1 unit tall standing on the collider below

[rustic current]

yeah i would say its likely thawt its so small that betwee fixedupdate frames, its glitching through the different triangles. Honestly, for map generation I would suggest you to not go with a collider mesh is always on for the whole map approach, that seems hard to maintain. Although, I've never done it before. but just imo

[heady lance]

have you tried just not falling through the floor
