sets prerequisites for armor and weapons, based on level and statistics
i.e. they are unequippable until the requirements are met
like in Diablo II

• set weapon prerequisites
• easy to configure arrays and case-when to set prerequisites

I love to see what my work is used for

do NOT use this script in a commercial game unless you get my permission first

OMG,,NAMKCOR!!! U r da man

/me bows

thanks, I try

--side note, unlike Diablo II, you can't fool this system with items that increase your stats (I tried making that an option, it didn't work) I might go back sometime to make that possible, but I don't think I will at this point

edit: ty for the move

Looks good NAM. nice work!

Sweet! I needed this.

ATTENTION
ANYONE WHO IS USING VERSION 1.00

I made the configuration sooo much easier to implement and organize
please upgrade to 2.10 k?
(you'll need to also re-add the optional Scene_Equip if you do)

Good stuff NAM. It's looking nice.

hehe, I don't think it could be more optimized
it's 41 lines with 5 pre-configs and no comments XD

One thing though: In the comments of the script you say requested by gameo, and then in the topic by SirMagus. Are they the same person? And yeah, the script is about as optimized as I could imagine. I'm a little cautious of the module, but I have no real reason to be other then preference. It's a very nice script. I think it might actually be better then using a data class in this case anyway.

d'oh, forgot to change the comments
I copy paste comments so I can just fill in stuff XD
