*Note: I created the most of the tutorials using the Roboblitz and Gears of War editors. Based on the engine, and the version, some properties specified may be in slightly different locations than what is displayed in the screenshots.

If you need to learn how to create a basic map I would reccomend:
For UT99, UT2K3 & UT2K4: the Unreal Wiki.
For UT3: Waylon's Tutorials.



Gate



A Gate controls the flow of signals and can effectively activate/deactivate other entities when used together.

• In: Signal comes in. If the gate is open, the signal will pass through and go out the out. If the gate is closed the signal is stopped.

• Open: A signal attached here will 'Open' the gate (if closed), allowing signals entering the 'In' to pass through the gate.

• Close: A signal attached here will 'Close' the gate (if open), stopping signals entering through the 'In'.

• Toggle: I've never toggled a gate, but I would presume that this switches between 'Open' and 'Closed' whenever a signal hits it.

• Out: The signal exits the gate.

• bOpen: If this is checked, the gate is open by default. If unchecked, the gate is closed by default.
