func_brush is a brush entity available in all Source games. It's a generic brush entity with various features.

It combines the functions of func_wall, func_illusionary, and func_wall_toggle from Quake and GoldSrc. The older entities can still be used, for an insignificant amount of memory saved.

Important:This is a preserved entity in .
If the game has round restart mechanics this entity may not behave as expected:

More info

On a new round entities with this classname will intentionally not reset. You can use logic_auto to emulate resetting it. Killing it removes it forever, as it is not respawned on a new round. It cannot be spawned with a point_template. Parenting this with non-preserved entities may have undesirable effects.

Note:The brush can be partly entered about 0.5 units. Other brush entities don't seem to behave this way (observed in by placing 2 brushes flush next to each other, making one func_brush and then when walking along them you'll get stopped at the point they meet which won't happen if for example func_wall_toggle is used)
Setting solidbsp keyvalue to 1 seem to fix the issue.

Keyvalues

Note:For Keyvalues and Inputs affecting brush rendering, see Brush entity/Rendering related keyvalues and inputs

Name (targetname) <string>[ Edit ]

The name that other entities refer to this entity by, via Inputs/Outputs or other keyvalues (e.g. parentname or target).
Also displayed in Hammer's 2D views and Entity Report.

Solidity (Solidity) <choices>

Used to control the solidity/collision of these brushes.

• 0: Toggle - The solidity can be toggled together with its visibility.
• 1: Never Solid
• 2: Always Solid

Bug:npc_combine_s can walk through no matter what type of solidity is set by using scripted_sequence  [todo tested in ?]

Solid BSP (solidbsp) <boolean>

Set this to BSP if the player seems to rotate oddly relative to the surface.

• 0: VPhysics
• 1: BSP (QPhysics)

NPC class excluded from collisions (excludednpc) <classname>

If an NPC classname (i.e. npc_zombie) is specified here, NPCs of that type won't collide with these brushes.

Note:Not usable with anything in

Invert NPC class exclusion (invert_exclusion) <boolean>

If set, then the excluded NPC class will consider this brush solid, and all other NPC classes will consider it non-solid.

StartDisabled (StartDisabled) <boolean>

If true brush will start invisible, and if solidity is not set to Always Solid it will also be non-solid

Tip:If Solidity is Toggle, disabling will also make the entity non-solid.

Flags

Ignore player +USE : [2]

Entity will ignore all Use inputs, including ones from the player.
