How do I limit spawn?

what i do for stop spawn mosnter after 5 monster for example???

i have look in every forum but no have idea...

i have a tree.. he spawn infinite enemy... for let spawn just 5 ?? or 20?? what i do?

You can have an instance variable on the tree that adds 1 when you spawn a monster and when tree.variable=5, you stop the tree from spawning by using 'if variable less than 5' as a condition.

ok solved this is way:

frist add istance variable "treespawn"

system, every 3 second add 1 to treespawn

sub event

tree "compare istance variable" <5 tree spawn another object

correct
