Invisible Walls Created 20 years ago2004-08-11 14:27:50 UTC by cyanide

how dyo make a wall that stops players getting past?

Just create a brush... world brushes always block a players movement...

i mean invisible wall

Cover it in the CLIP texture.

That will allow you to shoot through. To block bullets too, just tie something to func_wall, rendermode Texture, render amount 0.

I already though you left out some necessary information...

The func_wall can also be covered with the null texture. Then you don't need to worry about the render mode.

0 = invisible, 255 = solid.

You can also make a Func_wall with the invisible Texture and set render
to 255

G_KID: I'm not right all the time y'know

Captain P: the 'null' texture can do some odd stuff on some hardware. On my Machine compo map, it was stopping the face behind it being drawn as well!

Doesn't covering visible brushes with NULL give a HoM effect? Even with a rendermode of 0, I still think it would do the same thing...

The null texture only gives a HOM effect when no faces are rendered behind, wich can only happen when you cover a world brush with the null texture.

Covering entities with this texture shouldn't give problems as these do not block VIS. And all that happens during the compile is that these faces are left out... So Seventh, did you cover an entity with the null texture, or a world brush?

Ah.

World.

Then it's not some odd stuff on your hardware. What happens, is that you don't see the face as it doesn't exist. During the VIS process however, it was treated just like any other world brush/face. So faces behind it aren't rendered, whether you applied the null texture to it, or any other texture.

A good trick to prevent this is to check with gl_wireframe 2 on. Can you see wires behind the whole face, from every direction? Then you won't get a HOM effect when you cover that face with the null texture.

Ah, well, you understand by now, I guess...

Ah yes, makes sense. Thanks

rofl, kinda strayed off topic a little there lol
