ClearSurface?

| Hi has anyone go this to work, this is what I'm trying to achieve in my map editor... 1) Create a cube. 2) Create another cube right next door to the first cube. 3) Remove the surfaces (walls) between the 2 cubes to make a 'room' of 2 cubes. I guess I need to use clear surface but if I do that on a surface of the cube then the entire cube disappears... Any ideas how this can be achieved? |

| Instead of using cubes just use wall faces i.e. a single face of a cube. Make a 2D or 3D array which holds the wall positions (1) and empty spaces (0) , for example 1111111111 1000000001 1000000011 1111100011 1000000001 1111111111 then loop through the array, if theres a (0) then add a floor and ceiling surface to the mesh. If theres a (1) check the array above,below,left and right of the current position to see if you need to add a wall face to the mesh. This way you use minimal surfaces/verts and triangles to build your level so theres no need to go back and delete faces after. |

| Swift has a function to remove overlapping cube faces in code archives. |

| Rob, do you know where it is cos the search feature don't work on the forums these days :-( Shamber I don't want 'big' rooms i.e. I just want to connect cubes to together to make a 'rat-run'. How about I create 2 custom entitys, one with 1 face missing and one with 2 faces missing, then put them all together. |

| A blitz surface doesn't equal a single face. A whole landscape can be represented in a single surface. |

| I think you'll need two functions, both by sswift. AddMeshToSurface: http://www.blitzbasic.com/codearcs/codearcs.php?code=575 Remove overlapping triangles: http://www.blitzbasic.com/codearcs/codearcs.php?code=526 Cheers, Ryan |
