Timers and time spawn problem

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?

Here’s a picture of my code:

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.
