Branch | If

It takes a pulse to start the boolean state check. Either set the state directly on the node or connect another node to feed the boolean data to the branch node. It will send a pulse from either the true or the false output depending on the state the node has when it gets a pulse.

• Input: Pulse input to check the boolean state
• Value: Set a boolean state on the node or connect it to another parameter or node to get the state from another node.
• True: Passes through the pulse signal if the value is set to true.
• False: Passes through the pulse signal if the value is set to false.

Distance to Pulse

This node will track the movement of the listener or other components and send pulses when they have moved a certain distance. The distance is specified by the threshold float value. Note that the threshold needs to be set with the game engine's way of measuring distance in mind.

• Y: Tracks listener movement in the Y plane.
• Z: Tracks listener movement in the Z plane.

Note that pulses that come in during the waiting time will be thrown away and not stacked. Reset the timer with the reset socket with a pulse signal.

• Pulse input: Take pulses from another node.
• Reset: Reset the time cycle.
• Close Time: Set the maximum time that has to pass before sending another pulse.

Value change

This node will send a pulse each time its boolean state is changed.

• Boolean input/field: Change the boolean state on the node or a connected node to send a pulse though the pulse output.
• Pulse output: Sends a pulse each time the boolean state from a connected node or this node changes
