The spawning time is too fast. When I activate the spawn timer, it spawns to many enemies to fast. Is there a way to regulate the enemy spawning?
So increase the delay time.
Probably, but you’re being rather vague. How are you doing it at the moment? Maybe a screen snip of the events?
By the way when I fill the red space of the timer, it gets worse
there is no “of” for a scene timer.
change your object timer to a scene timer, then an enemy will spawn every 10 seconds.
