logic_gate is a point entity available in Strata Source 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. parentname or target).
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) <integer choices>
The comparison mode to use. Supported comparison modes are:
  1. AND
  2. OR
  3. NOT
  4. NAND
  5. NOR
  6. XOR
  7. XNOR

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 (Starting from 0)
GetValue
When fired, the logic_gate will call its OutValue outputs, 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
