Brush Entity

This entity creates a 'moving' conveyor belt. It can push things and simulate streams of water.

Attributes

Render FX (renderfx) - Gives objects special render effects. Think of it as modifying whatever the Render Mode puts out. The options are as follows:

0 = Normal
1 = Slow Pulse
2 = Fast Pulse
3 = Slow Wide Pulse
4 = Fast Wide Pulse
5 = Slow Fade Away
6 = Fast Fade Away
7 = Slow Become Solid
8 = Fast Become Solid
9 = Slow Strobe
10 = Fast Strobe
11 = Faster Strobe
12 = Slow Flicker
13 = Fast Flicker
14 = Constant Glow
15 = Distort
16 = Hologram (Distort and Fade)

Render Mode (rendermode) - Controls the type of rendering that is used for an object. Options are:

0 = Normal
1 = Color
2 = Texture
3 = Glow
4 = Solid
5 = Additive

Name (targetname) - Property used to identify entities.
FX Amount (renderamt)
FX Color (rendercolor)
Pitch Roll Yaw (angles) - Set the direction of push here.
ZHLT Lightflags (zhlt_lightflags)
Light Origin Target (light_origin)
Conveyor Speed (speed) - You guessed it, the speed the belt runs at.
Minimum light level (_minlight)

Flags

No push (1) - Enable this to prevent the entity from pushing things.
Not solid (2)

Notes

For this entity to actually look like it's moving, you need to use a texture with 'scroll' in its name (like 'scrollwater1'). Set the texture's angle to the direction of the conveyor's movement (the texture will only scroll in its direction, not the conveyor's (so you can't make it move sideways)).

With Not Solid enabled, there will be no push.

You can create your own push with a trigger_push entity, which gives you greater control.
When trying to push scientists (maybe some other monsters and entities too), they will "fly around like Mario Kart". To fix this, cover the whole func_conveyor with a trigger_push and set the speed of the trigger_push to 1.

If I was HephaIstos I would write a tutorial on this topic like a wriiting translation of this one https://www.youtube.com/watch?v=68HAHbxSgCI but for hl 1

Why is it when I set speed to "0", it still moves?

4 years later I still think it would be a good idea but I dare not bothering the smithing god with that. Indeed that would be too short a tutorial since this entity is basically straightorward : a brush with the scroll texture , tied to a func_conveyor . The yaw defines the steering. As for the angle of the texture, it is set with the Advanced texture tool.
Then a func_button which target is the name of the conveyor switches the steering for both the conveyor and its texture.

Anyhow the YouTube Hammer Quickies 6 is great, for a mortal that is.

With func_convenyor can simulate (not accurate) a "high gravity" (>800), it only works when you jump on top of brush

if yaw = down then:
-265< convenyor speed <-180

if yaw = up then:
180< convenyor speed < 265

-265/265 is almost normal "gravity"
if approaches to -180/180 it's like "disable" +jump.

With some triggers and multimanager can toggle on/off +jump of players, useful for gamesmode like deathrun or kz maps.
I have tested it on cs 1.6, i guess on hl it will work too

Also can be used as:

push for bhops, like axn mode.
map example:

carpets are func_conveyor

other maps examples (can download them from 17buddies): NOSLOW_TILES_BETA, NOSLOW_REPTILE, NOSLOW_BKZ_GOLDBHOP

The scroll speed of scroll* textures for the entities are encoded in a hacky way by hijacking FX Color (rendercolor) and you can control the speed of scroll* textures in any brush entity, and even change them with env_render (I tested, it works! 😁)

An algorithm you can use is:

R - 0 if positive, 1 if negative
G - abs(speed) // 16 (floor division)
B - floor( abs(speed) * 16 ) % 256 (modulo or remainder)
