logic_gate is a point entity available in 
Strata Source. This logic entity acts as a simple boolean value comparator with two inputs. When disabled, this entity will still accept inputs, but not fire outputs!
Keyvalues
- Name (targetname) <string>[ Edit ]
- The name that other entities refer to this entity by, via Inputs/Outputs or other keyvalues (e.g.
parentnameortarget).
Also displayed in Hammer's 2D views and Entity Report.See also: Generic Keyvalues, Inputs and Outputs available to all entities
- Start Disabled (StartDisabled) <boolean>
- If it should start disabled
- Comparison Mode (mode) <choices>
- The comparison mode to use. Supported comparison modes are :
- AND
- OR
- NOT
- NAND
- NOR
- XOR
- XNOR
Note:This is the internal order, which is used for the SetMode input. Note that they internally start from 0.Flags
- Spawn A enabled : [1]
- Spawn B enabled : [2]
- Output on every input (even if result doesn't change) : [4]
Inputs
- SetStateA
- Sets the boolean state of the A value
- SetStateB
- Sets the boolean state of the B value
- SetMode
- Sets the comparison mode. Input the index of the comparison mode as seen above - 1 (Starting from 0)
- GetValue
- When fired, the
logic_gatewill call itsOutValueoutputs, using the current result state as the parameter (0, 1). Similar to math_counter)
EnableDisable:
- Enable / Disable
- Enable/disable this entity from performing its task. It might also disappear from view.
Toggle:
- Toggle
- Toggle the enabled/disabled status of this entity.
Outputs
- OnResultTrue
- Called when the state is true
- OnResultFalse
- Called when the result is false
- OutValue
- Called when GetValue is fired. Automatically fills the parameter with the current result state (0, 1). Similar to math_counter
