Logic gate (Entity)

Entity description

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! Supported comparison modes are

1. AND
2. OR
3. NOT
4. NAND
5. NOR
6. XOR
7. XNOR

(This is the internal order, which is used for the SetMode input. Note that they internally start from 0)

Note:The OnResultTrue and OnResultFalse outputs will be fired on every state change, even if the result doesn't change!

Keyvalues

Start Disabled (StartDisabled) <boolean>

If it should start disabled

Comparison Mode (mode) <choices>

The comparison mode to use

Pitch Yaw Roll (Y Z X) (angles) <QAngle>

This entity's orientation in the world. Pitch is rotation around the Y axis, yaw is the rotation around the Z axis, roll is the rotation around the X axis.

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.

Parentname:

Parent (parentname) <targetname>

Specifies a movement parent. An entity will maintain its initial offset from its parent. An attachment point can be added to the end of the name, separated by a comma.

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_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
