Walking through walls collision problem

A couple of things you may want to try ..

If the house is comprised of several meshes - make sure you set the collisions for the children.

You may have small gaps in your mesh in the places that collisions are breaking during slide mode. This can cause this issue. Examine the house in more detail at a bigger scale.

If you say using stop collisions works - try backing up your player slightly when a collision occurs and see how this works ..

for c = 1 to countcollisions( player )
translateentity player, collisionnx( player, c ) * .01, collisionny( player,c ) * .01, collisionnz( player, c ) * .01
