The address is spontaneous. You have to either use a known initial value or catch it by hitting the enemy and finding values that got decreased by that much.
blah.
It's weird, I know a thing or two about programming, including the difference between a variable made on the stack, and one made on the heap, and nothing about pointers ever confused me, but CE's method of 'cathing' pointers makes me scratch my head every time.
I get the impression you may think 'I didn't use the pointer thing'. But my understanding is that if you DID, you could theoretically 'find' that hp variable without searching for it every time if you did, that the pointer would 'know' where it is each battle. grr.
edit: random armchair game design comment on touhou labyrinth. I don't know if 2 is guilty of this or not, but 1 is (and normally I compliment both but say where I think 1 is better)... but the game is kinda backwards (IMO) where early game gives you a good skill point to experience point ratio, not even counting how enemies drop items far more often (even if they are worth less, in PROPORTION, I imagine they are valued approximately the same, and simply drop more often).. but as you go further and further you find that the amount of exp they reward grows faster than the amount of skillpoints rewarded.. meaning that by being a noob and having to grind really early makes you stronger overall than needing to grind later on (unless it's at 27f with liliths).
I'm saying this not because I need to grind, but because I just realized I missed a flan event after I forgot about her completely and am backtracking to find it and am noticing a much better exp/skillpoint ratio. I've noticed it long ago but doing it again now just made me have to comment.
edit: k attempted flan half-assed ish 3 times at reimu 73.. can't be bothered. she can 1shot anyone with starbrow break, even with a hakurei barrier, even my tanks... slash dive can 1shot wriggle sometimes (depending on high or low), debuffs don't land reliably, even after 4 debuffs I get atk debuffed MAYBE once.. seems like a luck-based fight at this point with my setup. Maybe I'm doing it wrong but I tried various approaches and don't see how I can do things in a stable manner.. believe it or not I haven't wiped once and I'm doing this over-level 3 times and was like eff it really early. actually.. with yukari I reset at the start once cuz she used flying insect nest as her first attack on my first attempt which 1shot patchy (in the front), but on a second attempt she quad barrier'd someone and THEN insect nest, but she could tank it after a buff (Even though it pierces pretty good). IIRC.. I recorded it anyway, something like that I think.
I should upload my recordings (did one for alice, yuugi, eintei, yukari...and a few others but I forget who herp) because my HD is getting full, but takes so many timeses, sigh.
