I made a little picture and stuff to help people make these easier...
I actually wrote this for another forum but I decided to share here also.

Some good uses for these would be to make walls to block access to an exploit like on avalanche or battlebridge, not just spawns.


First pick a place there you want it (The origin). Then for the mins you specify how far left, right, forward, backwards, up or down you want to go using the mins and maxs.
The mins have to have a - sign in front of the number or the whole thing fails, the max must be positive.

To help show which min and max for the xyz doe I made two images...

Example...
The top image is a view from above, The origin is at the base of the arrow the arrow points the way the the entity is pointing.
The Bottom is from the side to show height, the center is where the two colors meet.

{
"classname" "func_team_wall"
"blockteam" "2"
"origin" "x y z"
"mins" "-x -y -z"
"maxs" "x y z"
}

-X = To the left of the origin
+X = To the right of the origin
-Y = How far forward of the origin to go
+Y = How far back from the origin to go
-Z = How low to go from the origin
+Z = How high to goto from the origin

Lets say you want to make a wall 20 thick, 100 long and 100 tall...Here is what it would look like.

{
"classname" "func_team_wall"
"blockteam" "2"
"origin" "-100 100 100"
"mins" "-50 -10 -50"
"maxs" "50 10 50"
}

This can be added with a ent file which you can find an example of in your dod:S gcf, with an entity editor like ented or entspy, or with stripper:source




Anyways, now that I have shared a new tip will somebody help me?

I installed Metamod:Source 1.23, Stripper:Source 1.01, and Mani 1.2 beta N Metamod version (DOD:S).

Metamod works, I type meta and it brings up the list of stuff.
Mani Works.
I type, meta list, and stripper is listed as running.

Yet when I put a known stripper config (rats (http://yr.rat.org/forums/viewtopic.php?p=648)) in my /addons/stripper/maps/ folder for dod_avalanche it doesn't work.

I tried it in both listenserver and dedicated server.
I've also tried disabling mani and just run meta and stripper but meta says stripper is still working.
