==Introduction==

In {{hl2|4}}, {{ep1|4}}, {{ep2|4}}; players occasionally encounter a scenario, where they must toggle a (rotating) button to achieve an effect or progress in the game.  
This page will describe steps on how to build a functional '''Rotating Button''' prop for use in your custom map, where:

* The player can {{mono|[[Use|+use]]}} the button object and it will turn to the ON position.
* With the '''Toggle''' flag option ''checked'', the player can repeat the {{mono|+use}} action and the button object will turn back to the OFF position. 
* With the '''Toggle''' flag option ''unchecked'', the button object will automatically return to the OFF position.

== Required entities and objects ==
A)  '''{{ent|func_rot_button}}''' (''This is a [[brush entity]].'')
:# Create a new texture brush on your map.
:# Use your editor's 'MOVE SELECTED TO:' feature to convert the brush from ''World'' to ''Entity''.
:# Set the entity's class as a {{ent|func_rot_button}}.
:# Name the entity "{{code|func_for_bttn}}".
:# Select and apply the brush-texture: "{{code|tools/toolsinvisible}} to the entity.
:# Set the following flags
::* '''Not Solid'''       ''Checked''
::* '''Toggle'''          ''Unchecked (optional)''
::* '''X Axis'''          ''Checked''
::* '''Y Axis'''          ''Checked''
::* '''Use Activates'''   ''Checked''

B) '''{{ent|prop_dynamic}}''' (''This is a [[point entity]] (Button prop).')
:# Place a new {{ent|prop_dynamic}} entity on your map.
:# Select its world model as: {{path|props_citizen_tech/firetrap_button01a|mdl|icon=file}}
:# Name the entity "{{code|bttn}}"
:# Select its Parent as "{{code|func_for_bttn}}"
 
C) '''{{ent|prop_static}}''' (''This is a [[point entity]] (Button pad prop)'') 
:# Place a new {{ent|prop_static}} entity on your map.
:# Select its world model as: {{path|props_citizen_tech/firetrap_buttonpad|mdl|icon=file}}.

== Set Inputs/Outputs (I/O) ==
# Set the following output trigger(s) in the "{{code|func_for_bttn}}" brush's [[Inputs and Outputs|I/O]].

:{| border=1 cellpadding="2" cellspacing="1"

==Place, Align, and Group the objects==
Follow these steps:

*Center the origin of the {{ent|prop_static}} entity (the button pad).
*Place the {{ent|prop_dynamic}} entity "{{code|bttn}}" into the desired position on the button pad.
*Place "{{code|bttn}}" and button pad into the desired position on the map (i.e equipment console or a wall).
*Set the desired [[Pitch Yaw Roll]] values for entity "{{code|bttn}}".  
*Center the origin for '{{code|bttn}}".
*Align "{{code|bttn}}"'s origin with the {{ent|prop_static}}'s origin ''as close as possible''.
*Place the {{ent|momentary_rot_button}} brush entity "{{code|func_for_bttn}}" over "{{code|bttn}}", making sure that "{{code|func_for_bttn}}" completely encloses "{{code|bttn}}". Allow enough extension of "{{code|func_for_bttn}}" for the player to ''touch'' it. 
*Center the origin for "{{code|func_for_bttn}}".
*Align "{{code|func_for_bttn}}"'s origin with "{{code|bttn}}"'s origin ''as close as possible''.  
*Set the X and Y values for "{{code|func_for_bttn}}" equal to the X and Y values of "{{code|bttn}}". 
:{{note|If you move and/or re-orient these objects to a different position in the map, repeat this step.}}
*Group all the objects. (You can also save the finished group as a [[prefab]] or [[instance]])
