ZDoom

According to tests, the amount of Strife upgrades cannot be tracked by their inventory amounts; doing so will instead spit out a string that tells you that the objects are quest items that don't exist.
Which can be quite a problem with Strife mods.

Thus, I propose that however ZDoom keeps track of these be exposed to the modders in some way, preferably in DECORATE, ACS, and SBARINFO. After all, the values are there, and they don't seem like it'd be harmful at all to expose them. Plus, these are things that are likely to fit in many mods, not just Strife ones. Besides, UpgradeStamina is fairly usable without this; it's accuracy sister isn't, but this will allow it use.

I'm not sure about DECORATE and ACS, but it can already be done with SBARINFO. Look under DrawNumber. Apparently was added in r2924. A workaround though, you might be able to change the stamina and accuracy items to give you a dummy item which can be counted. Just a thought.

That would work, but then it'd be absolute hell to remake Strife's status bar. x_x

Oh well, good to know they're already in SBARINFO. Too bad accuracy's still pretty much useless in it's current state..
