Defining Actor's Max HP with a Formula

[Exlo]

Okay I've been trying to figure this out all day, from simple trial and error to slogging through internet searches and forum posts. How can I, in the script box for a Common Event, use a formula to define an actor's Max HP (and MP, but I assume the process is identical)? Basically, what I'm trying to do is make the Defence stat influence how much HP is received per level. I'm trying out Hime's Level Up Events ( http://himeworks.com/2015/10/level-up-events/ ) to run the event at level up.

Basically, this is what I'm trying to accomplish  =>  this.mhp = this.mhp + (this.def * 1.5)

It seems like such a simple concept. :'c
I appreciate any help - maybe I can grasp some Javascript after having this one explained.

That is the part you can't do - the script box is sandboxed and anything defined inside will be erased as soon as the script box is closed.
You need to provide a method defined outside the script box but that can be called inside it, and that means you need a fully functional plugin to allow this.


That plugin needs to redirect the parameter formulae to its own area, and then can give you a script command to enable changes to that area from inside a script box or a plugin command.

Actually, you can do something like the op wants with the linked plugin.

But you have to create a Common Event for every actor.

@Exlo

Here's a screenshot from my Common Event for the plugin as an example. For your entire party you'll need the Common Event Queue plugin from HimeWorks too.

In this shot, the first actor in the database (by default it's Herold) gets his defense value as additional mhp, BUT it includes the defense values of equipement, too.

I would suggest that you think about some other values for this BD

Thanks for the quick reply. c:

Any advice on how to accomplish this? Or how to work up to being able to, I suppose? I've also tried looking at plugins I thought would be similar, but I suddenly feel even more out of my element haha

Edit: Oops ninja'd there. This looks more challenging than I originally thought, huh? I actually intended to have every actor have their own event for level-up. I wasn't even thinking about values added by equipment... Hm. I'm at a loss. I wanted the skills to have more depth, have more than one effect. There was going to be a system to distribute points into these base stats... but maybe I could do the same thing, but store all the player added numbers in a variable and call on that for how much HP/MP is added per-level. I set all the stats to be the same number on their curves, so it would just be a matter of adding the base value after that. I'll have to poke around, see what I can figure out. I appreciate the help!

Yes and no - that only works for additive formulae, because it only let's you decide what to add for each level - it doesn't let you set complete level formulae that are non-additive.

Basically you need to determine the mathematical formulae what to add where for yourself, and then use control variables to calculate the value before adding it.


It can be done with those events if you're using simple additions based on other values, but there are two points that you have to take care of:


1) recursive additions: your additions should only go in one direction, for example adding to HP based on DEF values. If you give every parameter an add based on other parameters, then you'll create a recursive effect that can easily skyrocket and is one hell of a balancing problem.


2) If you ever re-initialize the actor, all additions will be lost. To keep them after reinit the data would have to be in the base formula, and that needs the plugin I described above.

And that is exactly what the example from the opening post does

When do characters initialize, then? (Sorry, I'm awful new at all this.) I think I should be able to do what I want to do in the scope of the Maker's event commands anyways. Players will be able to add points to stats through another Common Event anyways, so I can just store the number of player added values in a variable as they place them, and increase parameters through the Change Parameters doo-hickey on level up. This also circumvents the equipment issue. However, this doesn't solve the dilemma if characters re-initializing overwrites parameter changes that way too. Though I'm not sure why it would, though, that sounds pretty restrictive. 

 

[kiriseo]

Honestly, I can't think of a scenario where you would re-initilize your actors in a running game.

The parameters from your actors will be stored in the savefile, so even loading a savegame wouldn't overwrite it.

That's a relief. I was worried there would be times I would want to or something and just didn't know it yet! I'm sure I'll learn the ins and outs in time, though. Thanks again you guys, I at least have a feasible game-plan now. c:
