How to make an object spawn one object at a time (with time intervals)?

Hello,

I'm trying to make a dart trap which activates when player is in it's line of sight (like in Terraria) and it spawns a dart every 3 seconds the player is in the LOS. However, when I move the player to the trap's line of sight, the trap spawns a LOT of darts in a row and it keeps spawning them until I get out of the LOS. I tried inserting time intervals in the action but it doesn't work.

The event looks like this: DartTrap - Has LineOfSight to Player > DartTrap - Spawn Dart on layer 1 (image point 1) > Wait 3 seconds

The 3 seconds action doesn't seem to work and the darts keep spawning.

Any tips appreciated,

Thanks

Thanks for the advice!

However I ended up solving it by making an instance variable (Shoot) which changes every 3 seconds the player is in LOS.

DartTrap - Has LineOfSight to Player, Shoot = 1 -> DartTrap - Spawn Dart on layer 1 (image point 1) > DartTrap - Set Shoot to 0 > System - Wait 3 seconds > DartTrap - Set shoot to 1

Maybe it's too complicated but it works :-)
