[B41] MaintenanceFIX

After investigating the maintenance skill in b42, i found that when the game calculates the maintenance mod, it no longer divides it by two, which means in all likelihood, the bug is fixed.

I have yet to confirm if the game modifies the maintenance mod when it asks for it, since I'm a novice programmer and I'm not really sure where to look. If somebody more experienced could point me in the right direction, that would be great.

Until further notice however, it will not be updating. For those still playing b41, it will still be up.


Removes 'dead' maintenance levels, by making weapons more durable at odd maintenance levels.
Also lets weapon skill contribute more to durability at levels 2, 6, and 10


So, as a quick recap in case you aren't aware of how maintenance works, each weapon has a chance of breaking when used. for example, a crafted spear has a 1/2 chance of breaking when used. Maintenance, alongside half the weapon skill, are directly added to the denominator of this chance. So a maintenance skill of 2, and a spear skill of 4, will both add 2 to the denominator of 1/2, making it 1/6. Now you are less likely to break your spear.


The problem here is that when the game calculates the number to add to the weapon's break chance, it divides it in half. Then, when it needs it actively, it multiples it by 2 again. The problem, is that java effectively rounds any decimals in these calculations down, meaning that odd maintenance levels contribute the same amount as the last even maintenance level, and only weapon skills 4 and 8 actually contribute to the weapon's break chance.

Here are some examples:
Crafted Spear Break Chance: 1/2. Maintenance level(ML) 1, Spear Level (SL) 3.
ML 1 / 2 = 0.5. Rounds down to 0. 0 x 2 = 0.
SL 3 / 2 = 1.5 Rounds down to 1. 1 / 2 = 0.5. Rounds down to 0. 0 x 2 = 0.
Spear break chance = 1 / (2 + 0 + 0) = 1/2. The same as a base spear with no levels.

Crafted Spear Break Chance: 1/2. Maintenance level(ML) 3, Spear Level (SL) 6.
ML 3 / 2 = 1.5. Rounds down to 1. 1 x 2 = 2.
SL 6 / 2 = 3. 3 / 2 = 1.5. Rounds down to 1. 1 x 2 = 2.
Spear break chance = 1 / (2 + 2 + 2) = 1/6. The same as if you wielded the spear with 2 less spear levels and 1 less maintenance level.


What my mod does is effectively nullifies this quirk in the coding by adding 1 to all weapon's base break chance at odd maintenance levels, and weapon levels 2, 6, and 10. It then removes them at even maintenance levels and weapon levels 4 and 8. There should be no way to tell the weapon's are modified unless you use the Show Weapon's stats mod or something similar. The mod modifies weapons when equipped, and it should work on any melee weapon, modded or otherwise.

Should be compatible with all weapons, including modded ones, as long as they are properly coded as melee weapons and use one of the vanilla weapon categories.

Also compatible with Maintenance Improves Repair, since that is a common question. They alter different things about the game code so there isn't any issues there.

None, report any you find!

This is my first mod! let me know if there are any strange quirks or anything, thanks!
