Some of OneShot’s maps have events that run once you enter the map.
They’re just events set to Parallel Processing trigger to run a few RMXP commands, then delete themselves.
Usually located in some corner of the map, and really hard to find sometimes.
Examples from the Barrens:
Disable fast travel indoors in the Outpost interior map.
Should be in all locations you don’t want the player fast traveling from.

Change the ambient lighting in the Start point map.
It applies a specific predefined tone via script, which is separate from the regular screen tone you can set, as it only work while Niko isn’t carrying the lightbulb.

Change Niko’s sprite to not wear the gas mask in the Docks map.
Most commonly used in the Refuge when going in to/out of buildings.
