Problem: Bullets Peircing Walls in CS:S Map

Greetings all.

I eyeballed through the forum and didn't find anything helpful.

My problem is this: I've created a map to learn Hammer and it's turned out really well for my first map since Duke3D, except for one thing.

While the map plays fine, all the walls and floor burshes are allowing Bullets to pass through. Like the common wood crate. Not breaking, but you can still get hit on the other side. This means that you can fire from one room into the next. Not good. And the really sad part is that just about ALL the guns are shooting through.

Now, I've had some suggestions from some of the other mapping sites, (I setup a small test range in the "backyard" of the map to try out the solutions I was given.), and none of them work.

Double walls (touching) allow the bullet to pass.
Double walls (with a gap inbetween) and the bullet passes BOTH.
Double wall with one wall textured with No bullet - BULLETS FIRE THOUGH BOTH WALLS.
Single wall with increased thickness - I end up with a wall like 15 feet thick before the bullets stop passing though it entirely. (Even a little damage passing though is not ok) Huge walls should not be the answer - because Valves maps have thinner walls than what I'm using and they don't pass bullets.

I've tried a great variety of textures to see if perhaps the textures I chose are the problem, but it seems the choice of texture doesn't play a role in ballistics, in the manner I need.

Is there a way to tag brushes, say, with an entity that makes them bulletproof (I.E. you can't shoot though it)?
Or perhaps there is a variable on the brushes themselves I can't find?

Please, help me out. This is frustrating me knowing I've got a good map aside from this problem.

Are these walls, world entites? i.e. they are not func_brush, func_detail, or func_wall.

check your compile log for errors. That could be a problem.

How thick are your walls in units? I tend to make most walls 16
units thick and 8 units thick if they are inside a home.

Also remeber that a rife bullet is able to shoot all the way through a
metal car, so a thin plaster wall would be like hot butter for a .50
rifle shot.

I'm working on a CS map ATM, I'll see if I have the same problem.

I couldnt find a definitive answer to how bullet penetration relates to brushes, so I decided to test it myself.

The numbers relate to how many units of standard world brush a particular weapon can travel through at 90 degrees to the surface.
It seems its units , not brushes that penetration(ooer) uses.

I hope this is of some use to people(took bloody ages).

Also, it's my understanding that the texture of the brush does effect the penetration (ex. stone texture blocks more than wood tex). But I may be wrong.

And how many units deep are your walls?

Yes, they're world entities, and have not been tied to any Func_entities. (aside from a few special cases that work the way they should, like Glass windows)

Thickness varies by brush, but the list you just put up should help me adjust the brush sizes to prevent the bullets from passing.

I quick check tells me that one of my thinnest walls is 8 units thick. So, I'll have to basicly double wall thickness.

Drat. Oh well. What must be done, must be done.

As for a 50cal round - I'm quite aware of the capabilities of the various weapons in terms of realisim - but this is Counter-strike. :razz: And just for the sake of gameplay,I'd prefer that, for the most part, the players engage each other directly, dispite what thier weapon could do to the real-world counter part.

Thank you for the info.

Theres a really simple solution to your problem, if you want to prevent bullets from penetrating a wall, instead of resizing the thickness of it, simply put a blockbullets brush over the wall. Problem solved.

BLOCK_BULLETS BRUSH WILL NOT WORK. TESTED IT YESTERDAY.

Nice post...

Intriguing stuff. Here's another noob question to lob at you:
What constitutes a "unit" in Hammer. I've noticed the numeric
length/width/depth values when creating brushes, but didn't know if
those were inches, meters, or what not. Is this the "unit" value
which you're referring to?

really? then you are doing something wrong because I have used this in my maps where I wanted it and it works just fine.

1 unit = 1 inch

Your grid scale in units can be seen at the bottom right of hammer, you
will also see the size in units of any selected brush in your grid
windows.

the block_bullet brush would not stop my bullets from going through to
the wall. I used a block_bullett brush of 2 units thick. I will test
again to be sure.

fun mapping.

Bah ... I have brick walls a foot thick and a carbine can shoot through them. :sad:
