[RPVX ACE] HELP WITH THE BATTLE FORMULA.

Ok so in my game, the PC's stats increase as they land attacks/are hit by attacks.

To make it so it only happens on a successful hit I am using the damage formula to apply these bonuses. Increasing Attack and Magic is easy. It's literally just adding an "a.add_param(3, 1)" before the damage formula, followed by a ; then the damage formula itself. With raising defence and hp, it's a bit more tricky. I want it to be so when the player guards and is hit, the resistance increases. So magic attacks increase magic defence, and physical attacks increase defence. This is easy, a simple "b.add_param(4, 1)" does the trick. Where I start to falter is here, I want it so that if the character is not guarding, their HP increases instead.

My current formula is this:
a.add_param(3, 1); b.isGuard() ? b.add_param(0, 1) : b.add_param(4, 1); a.atk - b.def

the problem is this does not work. I can make it so it increases one, or both, but not so it properly increases on based on the target's state.

Any tips? Am I doing the if statement wrong? I honestly can't figure this out.

Max HP, and no the bonuses are permanent, but many late game enemies are ridiculously strong. I have a script that raises stat caps to 999,999 and monsters reach it late game. Also without defense even early to mid game monsters will deal high damage.

Eh, weaker enemies increase your hp by one. Later enemies by slightly more. Rarer attacks even more so. Itd be very counter intuitive and poorly planned out to do that. :b

I jist realised i never said thanks. While there was some conflict with a script this did work. Thanks ^-^ <3
