HOW TO MAKE A VALVEWHEEL TURN ON/OFF (OPEN AND CLOSE)
Create the following in your map
1) A new texture brush and set it as a momentary_rot_button entity.
2) Ensure these flags are set:
Not Solid Checked
Toggle Checked
Use Activates Checked
3) A new prop_dynamic entity and browse/set its world model/skin as model:
valvewheel002.mdl
Bind these two objects together, making the momentary_rot_button entity as the parent of the the prop_dynamic entity.
4) Set the Name property for each of the entities. (Give each entity a unique, meaningful name.) For example:
momentary_rot_button Name = MyValveRotator prop_dynamic Name = MyValve
5) Set the Parent property of the prop_dynamic entity to the name of the momentary_rot_button entity.
prop_dynamic Parent = MyValveRotator
6) Set an output statemet in the momentary_rot_button entity's OTIP settings (i.e. Output, Target, Input, Parameter override settings in the entity's Properties | Outputs tab-page). Use the following values:
Output... OnPressed Target... MyValve Input... SetAnimation Parameter... Open
