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. The distance moved is synchronized between the momentary_rot_button and the targeted momentary_door i.e. a button halfway through its rotation would have opened the door halfway.

The momentary aspect of these momentary_* entities means you can have them be at any position at any time, instead of the usual [rotating] doors and buttons which travels automatically between the two endpoints (closed and open positions) on [each] use. Each use of a momentary_rot_button switches between opening or closing, which you can of course stop partway, except if the "Auto-return" flag is checked, then the button (and the target door) only moves towards the open position when USEd, and gradually moves back towards its closed position after being USEd.

A momentary_rot_button also mobilizes all other 'linked' momentary_rot_button that shares the same target. This can be used to make a "momentary rotating door" by having two momentary_rot_button's both targeting a dummy hidden momentary_door, with the other one having its "Door hack" flag checked. A "door hacked" momentary_rot_button is solid but not USE-able, and vice versa. Care should be taken so that all 'linked' buttons has the same total travel time and go the same way (+ve distance), or the buttons will de-synchronize.

momentary_rot_button entities 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.
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.

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

- 2 = Texture
- 3 = Glow
- 4 = Solid
- 5 = Additive
FX Amount (renderamt)
FX Color (rendercolor)

Distance(deg) (distance) - Distance in degrees the button will rotate. Positive distance rotates counter-clockwise, and vice versa (using right-hand rule). Negative values not recommended, see notes.
Speed (speed) - Speed the button will turn. Defaults to 100 if blank or 0.
Auto-return speed (returnspeed) - For buttons with Auto-return flag enabled, the speed at which the button will return to its starting position after being used.

Light Origin Target (light_origin)
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. Then one button moves the other "door hacked" "button".
Not useable (2) - Seemingly unused.
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. You can instead unlink/relink the button to the door to achieve the same effect. See below.
It is possible to unlink this button from its door with a trigger_changetarget. A button with a blank target will be unusable, effectively disabling it. 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.
CLIPBEVEL
A solid "door hacked" momentary_rot_button that is vertical (i.e. rotates around the X or Y axes) would have weird collision round its edges due to the clipnode distances generated for it differing between vertical (36u standing/18u crouching) and 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_button's have a tendency to skip the final update, leaving the target momentary_door slightly ajar. This needs 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 revert to its initial pitch values. The previously mentioned issue also tend to leave the ambient_generic at very low droning pitch instead of turning it completely off.
This entity only works well with positive distance. Entering a negative distance value will cause unexpected behaviour, such as the door starting open.
- A trick to have the button rotate clockwise while still having positive distance is to flip it 180 degrees: build the brushwork flipped 180 degrees, and an angles value that flips it back the right side (e.g. a spigot facing east in game faces west in the editor instead, and has Yaw set to 180). You need to double check the center of the origin brush where the flip will happen as well as consider the lighting conditions.
Linked momentary_rot_button's (those sharing the same target) should have the same forward (and return) travel times (easiest by having all distance/speed/return speed/"auto-return" flag be identical), otherwise they will de-synchronize between each other. Some of the buttons could end up being out of their nominal range of motion (and therefore send a value outside the 0-1 range to the target). However, they will all "snap" back to their proper open/close positions when the main one reaches its own endpoints.
- If you need a pair of linked momentary_rot_button's rotating the opposite directions, one of them needs to be flipped using the method previously mentioned.
To detect if the momentary door/button pair is within some range of positions (as part of gameplay – see Uplink), use the momentary_door(s) to push a func_pushable through one "in range" trigger_multiple entity, which in turn is sandwiched between two "out of range" trigger_multiple entities, with all three triggers having the "Pushables" flag set. Tip: Use BEVEL texture on the triggers for precise non-overlapping trigger area.
You can remote control a momentary_rot_button by triggering it in 0.1s intervals. For auto-returning buttons, it will only move towards open position while being triggered, and return towards its closed position when this trigger pulse ceases. Otherwise, it will flip-flop between opening and closing when it reaches its endpoints. Unfortunately, you cannot set the button's position as you could with the door.

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.
