1. Open the map you want the flashlight to work on.
   
2. Using the Timer tool, place a timer on the map.
   
   1. Set the Initial Delay to 0 seconds.
      
   2. Set the Every Interval to 0.05 seconds.
      
3. Select the Every Timer Tick trigger and then press the Edit Script button

Notes

When handling lights in 001 Game Creator, care must be taken, as abusing the lighting system will cause significant performance issues. If you notice performance issues try reducing the size of the light, or increasing the Every Interval delay of your timer. Reducing the number of lights on the map will help as well.
