how about setting your ships recharge to a negative number, and set the BulletFireEnergy to a negative value as well... Firing bullets will 'recharge' your energy, and doing nothing will drain it. But then, if you want to explode at full power... that might be harder... with ASSS I guess it would be easier, but a subgame bot could do it as well, as it can read energy. One detail, you will spawn with 'full' energy... unless... maybe if you put alot of initial greens, and set the negativeprize factor to something big (or small, whatever gives you alot of them), and set prizeWeight of FullRecharge green to something big too... When spawning, you should receive a couple of greens, and you might receive a 'energy depleted' one. I'm not sure if negative prizes can be given at spawn though. But then again, a bot could easily prize you a energy depleted green when spawning
