Suddenly, a summer breeze...

Hey folks. I've begun to work on a project again, and had a query to make a certain type of buff or debuff in-game. Because I don't feel the title can convey what I mean, here's an example.

Say I'm trying to create an AD&D-esque system for a game. In this case, I'm trying to make buffs and debuffs that can increase or lower a target's "Armor Class", or AC -- an exact number that must be met or exceeded to hit something. I already have the hit formula figured out to simulate a dice roll with modifiers to hit something's AC, as per the game system.

The problem is, however, that I need to increase or decrease these bonuses by precise numbers, as opposed to percentages, in-game. For instance, I need a "Shield" spell that raises the user's AC by +4, which would correlate to raising the DEF score (which I'm using as AC for this hit % formula) from, say, 12 to 16 in this case. If I were to use a percentage-based system, it'd be a ludicrous boost if I gave a version of this to a high-AC hero (a 50% bonus would cause 18 AC to become 27, for example -- impossible to hit with normal attacks with my system with the proportions used in-game).

All-in-all, hoping for a way to give an exact numerical boost (i.e. +4) to a built-in stat as opposed to a percentage-based one (i.e +50%). I'd imagine there's a way to do it in a Skill's damage formula, and am hoping so instead of having to rely on a script? I'm not as well-versed in damage formulas using VX Ace or MV as I'd hoped, if so.

Actually, this will take a script, as ACE and MV were never designed to do + or - those base stats in a state. However, if you can use a xparam or such to mimic AC, then you can just add to them. But that would take a script in the first place to even replace an xparam with AC anyways.

Just a little close up shot...
finally drew the last member of "team outcast" for my game. since my game has a lot fighting game elements in it, there's bosses in teams of three like King of Fighters.

Let's continue making our game in MZ! Touchfuzzy is... still eventing... though this time we may be working on eventing some tutorial stuff for our players!

I work late on the game so I sleep in then I wake up late so I have to work hard to make up for sleeping in meaning I work late again and sleep in again... what a nasty cycle.
