CDR and RCR Percent plugin

[JarJarD3]

Shows your total CDR and RCR percent in Inventory header.

Optionally shows CDR values for those items that can have CDR on them.
Optionally shows RCR values for those items that can have RCR on them.

Green value is max CDR available.
White value is max CDR available and can not enchant it as other attribute has been enchanted already.
White value with plus-sign is CDR that can be enchanted (up to max value).
Red value is item without CDR and can not enchant it.


As I don't know exact specifics about RCR per item, I used range from 5.0-8.0% for all items except Yang's Recurve 40.0-50.0%.

This might have some usage with new S18 Captain Crimson’s Trimmings set.

Inventory image example.

Inventory images with RCR on items (but not right colors as old image).

Version history:
- add RCR range check (5.0-8.0%)
- added RCR number on equipped items (below CDR number).
- add NRE check for item.Affixes

I like it, it will be useful for next season. Captain Crimson's set seems like a good set for farming builds.
You show only the cdr of each item, you could do the same with the rcr in the lower right corner (or just below the cdr), or make it optional at least.
The color code would simplify it: green if it reached the maximum value, red and orange if they have not reached it, and it will be orange if it can be achieved by enchanting the item. But this preference is personal, I will make this modification for my own use if I decide to play the first days of the season

I'll try to do it.
It seems (according to my item database) that RCR can not be found on these items:

• belt
• boots
• bracers
• chestarmor
• helm
• pants
• (follower item)

So the item search must be changed to handle this.
And I would place RCR below CDR for simplicity.

[JarJarD3]

Added RCR number on equipped items (below CDR number).
Check new example images.

As I don't know how RCR is available on items (min-max) and there is special item buffs for RCR this only shows current RCR value or if it can be enchanted to have RCR.

this little great thing somehow got broken with latest release, tried to fix it:

        {
            var affix = item.EnchantedAffixNew != 0 && item.Affixes != null ? item.Affixes.FirstOrDefault(x => x.Id == item.EnchantedAffixNew) : null;
            return affix != null && affix.Mods.Length > 0 ? affix.Mods[0] : null;
        }
    }
}

I was too lazy to refactor the method that checks the value, I'm sorry
