• AddOutput <string>

Evaluates a keyvalue/output on this entity. It can be potentially very dangerous, use with care.

Format: <key> <value>

Format: <output name> <targetname>:<inputname>:<parameter>:<delay>:<max times to fire (-1 == infinite)>

Divides the the math_counter's value by the given value.

• SetHitMax <integer>

Changes the Maximum Legal Value to the given value.

• SetHitMin <integer>

Changes the Minimum Legal Value to the given value.

• SetValue <integer>

Changes the math_counter's value to the given value.

• SetValueNoFire <integer>

Changes the math_counter's value to the given value, but doesn't update the change to any other entities.

• GetValue (New with Orange Box)

Outputs

• OnUser1-4

!activator = activator

• OnKilled (New with Left 4 Dead)

Fired when the entity is killed and removed from the game.

• OutValue <integer>

Simply sends out the math_counter's value as though it were typed into the the parameter override field. Useful in conjunction with logic_case or func_movelinear. The change is outputed each time the value changes unless the SetValueNoFire is used.

• OnHitMax

When the Maximum Legal Value is reach this output will be sent. In order to trigger it again you will need to alter the value first.

!activator = activator

• OnHitMin

When the Minimum Legal Value is reach this output will be sent. In order to trigger it again you will need to alter the value first.

!activator = activator

• OnGetValue <integer> (New with Orange Box)

Outputs integer value in this entity
