*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.



Timer





Timers are very similar to delays in that they count time, however the time is an 'active count' and stores the amount of counted time in an external Float value.

• The Time is how much time is counted between when a signal hits the 'Start' and another signal hits the 'Stop'. This can be stored in an external float variable so you can record how long it took something to do something.

• A signal will not output through the 'Out' on a timer unless the timer is 'Stopped' - unless a signal hits the 'Stop'.

A timer should not be used like a 'Countdown Clock' or something similar - use a delay for that. A timer is basically used to measure time in-game: it will tell you, through the float variable, how much time passed between a signal hitting the Start, and another hitting the Stop.
