Hi all.

I am in the process of adding a mining skill to skyrim, so that the result of mining will depend on a skill check.
See below, modifications start and end with FRON_START and FRON_END

So I created a global variable to store the mining experience of the character, and I added it to the native "mineOreScript"

So the Native Mine Ore script has a new property (the global variable) that needs to be defined for every use of this script.

This script works very well ingame except the fact that the global variable isn't modified (so the character never improves...)

I tried really hard to modify all the many base objects that use the "mineOreScript", but the world various Ore deposit dosen't seem to take the new global variable into account, although the various modifications work really well.

So my questions are:
Is there a fast way to modify all the references in the world ?
Do you think I could store this global variable in an other way ?

I am pretty mad now, because I can't finish and release both my skinning and mining skills in a proper way (that is, not only random results, that is the easy part, but also so that the character can improve himself over use...)

Did you try with a new character already? Scripts, once created won't necessarily be updated to the new one.

Actually, on one vein ore in the world, it worked (the character gained XPs), but I can't remember precisely what I did.

Well, it could be that this particular ore vein was new (you never visited that cell before), resulting in attaching your updated script. That's exactly why I am asking.
I haven't figured out all the new persistence complications yet but, this this might fit the bill.

Hmmm, indeed. I will give a try to your solution anyway, tx for tipping

But if anybody has another solution or proposition, PLEASE share

I tried, It doesn't work. Actually, showvars from console tells that my global variable is none, so the global variable property is not attributed to the defined global variable. Anyway to do this esily for all the Ores of the game ?

This is really pissing me. Why can't we define a global variable as simply as an integer ? I am soooo mad at how complicated it is to simply define and use a global variable, come on bethesda or anybody, please fix this....
