hmmm. im probably retarded because no one seems to understand :(
i want each wave to be completly different and easy to cuztomize. maybe a group for each one, wave1 (8 monster, that spawn at every 3 seconds, with 5 health), wave2 (6 mmonster that fire at player, spawn at every 2 seconds), and so on.
the only thing i want to stay the same for each wave is for how the wave is activated and that when every monster is dead there is a pause of 5 seconds and then we move to another wave.
