ok, last thing i have left for this game is to get the hp to scale when it finishes waves 5, 10, 15, etc (boss waves) and starts the spawning over again. i go the wave system fixed so it will spawn them, then when they all die a timer comes up to count down till the next wave, then the next wave starts. i have it where it spawns from 5 different enemy units depending on the wave number (hence the inc hp after waves 5 and so on).
here's a link to the scenario: http://www.greenfoot.org/scenarios/8919
i put some coding i thought would work in the spawning class, but it didn't change their health, so i commented it out.
