[1.0.7] Cant go up stairs when the front face isn't perfectly vertical due to rounding errors

Recommended Posts

Im using this image as an example. Player is moving left to right. The first step is fine, second step you can not go over. I tested in q3 and the way it handles this issue is if you are going really slow it will stop you otherwise you go up like a normal step.

Now you might be thinking but mad this isn't meant to mirror q3 movement 1:1. The problem isn't reflexs movement accuracy to q3. You are meant to walk up stairs, specifically you can step up/on on ledges even 16u high.

The problem is when making stairs sometimes a step can end up off grid because of rounding errors. Even a teeny tiny rounding error can cause the step to be impossible to go up.

Imagine the vertex by the red circle is off grid even a tiny bit and the rest of the verts are on grid, this will cause the step to be broken. I have seen this on a few maps now and only really figured it out a while ago what causes it.
