In L4D (others maybe too) there is an entity named env_player_blocker. This entity is a point entity, and thus invisible. it also has these two properties that set the bounds of the entity (which blocks players from entering those bounds)

"origin" "6664 3918 608"
"mins" "-4 -90 -70"
"maxs" "4 80 80"
"initialstate" "1"
"BlockType" "0"
"classname" "env_player_blocker"

The mins and maxs set the bounds, creating a box of some sort. This is hard to create in the game as you can image, since you cannot visually see the bounds of the entity.

Can someone create a visualizer that would paint the bounds of this entity?

Some other handy things would be
1) Set entity position to where I'm pointing
2) Adjust entity XYZ position by VALUE
3) Set mins\max
4) set BlockType to 0,1,2
5) dump data out to text file of the current pointed-at entity

I don't think it's possible to create a brush entity from a plugin.

The closest a plugin can get is to check player position and teleport them out of the box. I have done that before.

Not create a brush entity, draw something on the screen. cant you draw lasers from one point to the other some how?

I think he need it to Stripper.

Im not sure if there already is a way of drawing the entity box by just supplying its entity index, possibly with a command or whatnot. Anyhow, you surely can draw it yourself line by line. See TE_SetupBeamPoints (dont forget to send it after the set up... such a common mistake ).

Threw in a function that should help you get the absolute bounds of the entity to be drawn. Have fun working out the math how to draw each line, its not that hard but may take some time if you suck at maths like I do.

PHP Code:

//returns false if entity has no bounding box
bool:GetAbsBoundingBox(ent,Float:mins[3],Float:maxs[3]) {
    if(!GetEntSendPropVector(ent,"m_vecMins",mins)) {
        return false
    }

    decl Float:origin[3]

    GetEntPropVector(ent,Prop_Data,"m_vecAbsOrigin",origin)
    GetEntPropVector(ent,Prop_Send,"m_vecMaxs",maxs)

    mins[0] += origin[0]
    mins[1] += origin[1]
    mins[2] += origin[2]

    maxs[0] += origin[0]
    maxs[1] += origin[1]
    maxs[2] += origin[2]

    return true
}

bool:GetEntSendPropVector(ent,const String:prop[],Float:vec[3]) {
    decl String:class[32], offs, PropFieldType:type

    if(GetEntityNetClass(ent,class,sizeof class) && (offs = FindSendPropInfo(class,prop,type)) != -1 && type == PropField_Vector) {
        GetEntDataVector(ent,offs,vec)
        return true
    }

    return false
} 


In case you dont feel like looking for a sprite to use with TE_SetupBeamPoints yourself, heres one Ive been using: "materials/sprites/bluelaser1.vmt".
