momentary_rot_button - Brush Entity

A momentary_rot_button is a rotating button that requires continuous use (e.g. holding the USE key) to slowly affect the position of a target momentary_door over time.
If the "Auto-return" flag is checked, the button (and the target door) will move back to their initial position when it is stopped being used. Otherwise it will toggle between opening and closing on each use.

The way momentary_* entities work is via synchronizing the percentage between close and open positions across all linked entities, meaning a momentary_rot_button rotated halfway through its travel distance moves the associated momentary_door likewise halfway to its open position.

The target momentary_door will also actuate all other momentary_rot_buttons that target it. This can be used to make a "momentary rotating door" by having its "door hack" checked. Then have both entities target a dummy hidden momentary_door. A "door hacked" momentary_rot_button is solid but not USE-able, and vice versa.

momentary_rot_buttons are also used by func_mortar_field for targeting air strikes, one for each axis.

For the normal rotating button, see func_rot_button.

Attributes

Name (targetname) - Property used to identify entities.
Pitch Yaw Roll (angles) - Sets the pitch (up / down), yaw (left / right) and roll (bank) respectively. The compass in WorldCraft / Hammer corresponds to Yaw. The settings are not always (or not all) used.
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
Master (master) - The name of a multisource (or game_team_master) entity. A master must usually be active in order for the entity to work. Thus they act almost like an on/off switch, in their simplest form, and like an AND gate in the case of the multisource. Note: momentary_rot_buttons can always be used, regardless of the state of their master.
Targeted Object (target) - Normally, the momentary_door you want to control.
FX Amount (renderamt)
FX Color (rendercolor)
ZHLT Lightflags (zhlt_lightflags)
Light Origin Target (light_origin)
Speed (speed) - Speed the button will turn.
Sounds (sounds) - sounds values
- 0 = None (common/null.wav)
- 1 = Big zap & Warmup (buttons/button1.wav)
- 2 = Access Denied (buttons/button2.wav)
- 3 = Access Granted (buttons/button3.wav)
- 4 = Quick Combolock (buttons/button4.wav)
- 5 = Power Deadbolt 1 (buttons/button5.wav)
- 6 = Power Deadbolt 2 (buttons/button6.wav)

Distance(deg) (distance) - Distance in degrees the button will rotate.
Auto-return speed (returnspeed) - Speed at which the button will return to its starting position after being used.
Minimum Light (_minlight)

Flags

Door Hack (1) - Makes this entity solid, but un-USE-able (and vice versa). Thus the only way to actuate this entity is for it and another, normal momentary_rot_button, share a momentary_door target. So that button moves the door, and that door in turn moves this "hacked door".
Not useable (2) - Button must be triggered to work.
Auto return (16) - Button returns to its starting position automatically after use at the speed set in Auto-return speed (returnspeed).
X axis (64) - If enabled, the rotation will be on the X axis.
Y axis (128) - If enabled, the rotation will be on the Y axis.

Notes

Non-solid by default, unless ☑️ Door Hack (1) flag is checked. (Note that "door hacked" entities are not USE-able.)
If neither of the axis flags is enabled, rotation will default to the Z axis.
An origin brush needs to be part of the entity to specify its axis of rotation.
A momentary_rot_button or momentary_door cannot be disabled by disabling its master.
It is possible to unlink this button from its door with a trigger_changetarget. Linking it to a door again will snap that door into place, depending on the position of the button.
Setting Pitch Yaw Roll (angles) rotates the entity by that amount on spawn. Use this together with X/Y axis flags to orient the entity to rotate off-axis.
A helpful comparison between momentary_rot_button and func_rot_button is as follows:

Aspect	func_rot_button	momentary_rot_button
Movement	rotates around origin	rotates around origin
Pitch Yaw Roll	rotates the entity by that amount on spawn	rotates the entity by that amount on spawn
Target	Anything (e.g. `func_door`)	`momentary_door` or `func_mortar_field`
Use type	Instant	Continuous
Make toggleable	☑️ "toggle" flag	☐ "Auto return" flag and return speed == 0
Make resettable	After wait time and ☐ "toggle" flag	☑️ "Auto return" flag and return speed > 0
Target timing	At end of movement	Continuous with movement

A solid "door hacked" momentary_rot_button would have weird collision round its edges due to the vertical clip distance generated for it (36u standing/18u crouching) being different than the horizontal (16u). You can add zhlt_noclip 1 keyvalue to remove the default clip generation, then tie to the entity a clip brush extended uniformly at the edges (say, 27u) with CLIPBEVEL texture round the edges.
Auto-returning momentary_rot_buttons have a tendency to skip the final update, leaving the target momentary_door slightly ajar. This need to be accounted for when designing the momentary_door.
A targeted ambient_generic will modulate its pitch to the relative position of the momentary_rot_button. However this is only transient and activating the ambient_generic any other way will reset to its set pitch values. The previously mentioned issue also tend to leave the ambient_generic at very low droning pitch instead of turning it completely off.

Findings:

Door hack flag makes the entity un-use-able but solid (default is useable but not solid)
Not useable flag has no effect [not implemented?]
[bug] the entity only works well with positive distance (clockwise opening). Negative distance makes the internal value "start open". The linked momentary_door will always be opening when the momentary_rot_button moves clockwise and vice versa.
- solution: have all linked momentary_rot_buttons have positive distance, and rotate the entity's yaw 180 degrees to make it spin counterclockwise (and now lighting needs to be taken to consideration)
[bug] [Related with negative distance also,] if there are 2 or more linked momentary_rot_buttons and the other has different signed distance then the other button will keep spinning past the end (and the internal ratio value would go past the 0 ≥ x ≥ 1 range)
- solution: same as above
If 2 or more linked momentary_rot_buttons have different distance/speed the one being USEd will dictate the speed and distance of the others. Then when it reaches the full distance all the others will snap to their fully opened/closed positions.
As per RUST: Creating Proximity Doors triggering the momentary_rot_button every 0.1s does move it at the prescribed speed, but if "auto return" is not set it'd just continually ping-pong between opening and closing.

[2024-06-05]
This is common knowledge amongst pro mappers but the momentary_* setup is used on Uplink and Blue Shift for the dialing-in sequences through an off-the-playable-area setup where the momentary_doors push a func_pushable through several trigger_multiples that have "pushables" flag set. One of them is the "correct, dialed in" position, the others unset it.

One very basic application for this that I can think of is replicating HL2 Route Kanal sliding gate setup locking at its open position by having a trigger_once at the very end of the momentary_door, and when the func_pushable touches it, kills the momentary_* entities and replaces them with func_wall_toggles of the setup frozen at their final positions.
