How to find the -real- max_hitpoints?

[Ken_Oh]

I can't find a unit's real max hitpoints as a value. It's a variable that should be there, but isn't.

Here's what a Strong and Resilient Spearman looks like:

Code: Select all

[unit]
	hitpoints="42"
	id="Spearman"

	max_hitpoints="36"

But here is a Quick and Intelligent one:

Code: Select all

[unit]
	hitpoints="34"
	id="Spearman"

	max_hitpoints="36"

This causes some problems when you're trying to alter units, as Bob the Mighty has found out: http://www.wesnoth.org/forum/viewtopic.php?t=17638

I'm running into similar problems now that I'm trying to code healing abilities. The problem is, unlike Bob's scenario, I want my healing to be able to interact with canrecruit=0 units, with traits and potential AMLAs.

I don't know a whole lot about programming, but it just seems really odd to have a value that you can see on the screen yet you can't find in the code.

Anyone have any idea how to get around this? Is that variable hidden somewhere?

Well...you could store the units hitpoints= on recruit, scenario start or whenever you know it's in full health.

Also, you could store the units hitpoints=, use an [object] to heal it to full, check/store the hitpoints= then, and revert them back to the original value.

But yes, I'd agree that it'd be best if these things were directly available in some key. Same applies for experience=, AFAIK.

[Ken_Oh]

Experience is indeed the same. At least I don't see a need to alter them too much.

I'll try your second suggestion really quick.

EDIT: That works perfectly. Thanks!

Honestly, I was afraid you were going to say that I should figure for all of the modifications myself with a bunch of FOREACH loops to find the true hitpoints. I'm really glad you had a better idea.

The same applies to the movement points, and counting the upgrades to the original value doesn't even work for me...

It must if you do it correctly. The game doesn't cheat on WML saves.

Ken Oh, could you post an example of WML that you got to work?

Sorry, I'd break it down better but I gotta go.

EDIT: I guess there isn't too much to break down. Feel free to ask questions if you need.
