u maybe said that u needed a greater varity, but you have alredy got simplest solution, and promise me, it is working just fine, as i always use. simply use
rem health is your healt
health=2000
rem ehealth is your enemy's health
ehealth=5000
rem add this into the batle routine,(or the main loop if thats where you keep your battle sequence
rem lets also assume that you got a subrouine for winning named _youwin
if health2=< 0 then gosub _youwin
You see? it cant be easier
