i set it to 600 and spawned 3 not 5. the problem is: at the first time 3 are spawning, the second time 6,the third 9,the fourth 12 and so on. i think its something like that: the counter counts to 600 one time,do the spawn. the counter counts to 600 twice, do the spawn twice. and so on how can i "refresh" the counter? isnt counter = 0; enough? and another problem: when all gegner1 die before the counter counts to 600 theres no spawn. i think because theres no gegner1 left who can run the method. edit: when theres only 1 enemie alive 3 are spawning when the 3 are alive 6 are spawning but when i kill 3 and only one is alive 3 are spawning.

I get it. Each gegner1 object has a seperate counter that is being used to create more of them. Move the code to create gegner1 objects out of the gegner1 class and into the world class code.
