I need help with enemy spawning and timers

Hello, I'm working on my first game and I want to make it an enemy wave survival, but I just got stuck in the part where I make the enemies spawn at the beginning of each wave, and I couldn't find anything that could help me on the internet so I created an account to ask you guys.

I need to know how to make a fixed amount of enemies spawn at the same time in the same or different locations when the timer goes to 0, and then make the game to wait until the player has defeated them all, and then the timer would reset and when it reaches 0 more enemies than before will spawn, and so on and so forth.

What happens to me is that when the timer reaches 0 the enemies start to spawn infinitely until the max object limit has been reached, and I'm left with 900+ enemies chasing me.

If you know how to fix this issue please answer.

Thank you!

you can limit the amount of enemies created by doing something like this

>if timer = 0
>amount of enemies < "desired_amount"
-create enemy

then you can do something like
> if timer = 0
>count enemies >= "desired_amount"
-reset timer and add +1 to the "desired_amount" or whatever extra amount you want for the next wave.

theres many others ways to do it, let me know if this one works for you

Thank you, I had guessed it would be something by that style.

But I still don't know how to actually program it :P

Could you please show me how to do it?

There are a variety ways of doing this - attached is 1 example.

Thank you!

It really did work for me.

But how do I make it so that the quantity of enemies goes increasing for each wave without the previous restrictions stopping them from spawning?

Thank you, I will be trying to find a solution too.

With a calculation - see attachment.

Thank you very much!!
