[quote:1a4frg80]I would also like to understand what is the purpose of the line System-trigger once after the spawning? Does it prevent to generate the action twice while the car is still on the layout or not destructed yet?
I am not sure why I used it there without looking at my event but anytime you have an event where the conditions are not specifically triggered once (aka collision) then you need to trigger it once or else it will be run 60x a second (each tick)
Yes these are definitely needed for performance reasons. Somehow 3 of them got lost in my mods, but there should be one after each of these 3 lines
TreeSpawners: SpawnerTreeType /= 0
ObstacleSpawners: SpawnerObstacleType /= 0
CarSpawners: SpawnerCarType /= 0
Still, no extra events
Edit: here it is

Edit 2: hm for some reason that stops the cars and trees from appearing, but I don't have time to look at it right now. Exercise for the reader!
