All entities have a Use input, though many do nothing in response to it. There are four methods to invoke it:
- A player looking at the entity and using the
+useconsole command (this is normally done by pressing the e key) - An entity output that specifies the
Useinput, or not specifying any input. - Directly calling the C++ function
Use typically performs the action players most expect when interacting with the entity (e.g. opening/closing a door, picking up a physics object).
If an entity without a use function is parented to one which does, it will passthrough the input to the parent.
Programming
Although there is always a Use input, the actual Use function of an entity starts null. It can be assigned at any time with SetUse( void *SomeFunc(CBaseEntity *pActivator, CBaseEntity *pCaller, USE_TYPE useType, float value) ).
It doesn't appear possible to specify USE_TYPE or value through the I/O system.
