I want everything related to the script to be a part of the same script - telling people to download multiple mods just to fix a bug isn't it

I think you don't know MixSets. The goal of MixSets is literally what you said right now, is almost 300 tweak options (including dozens of fixes) in the same mod so people don't need to download multiple mods to fix the game.
So, just like you said, use MixSets instead of adding multiple mods to fix the game.

I think you didn't understand the problem. It comes from KeepNoAmmo and Reload Mod cross-compatibility - we don't have MixSets installed here (let's assume we don't, anyway). When the ammo stays at 0 it doesn't auto-reload and KeepNoAmmo expects that - but it breaks when the ammo refills by scrolling the wheel.

What you suggest is for that person to install MixSets (again, in the scenario let's assume it isn't already) just to fix the issue that comes from two existing mods, whereas I can simply integrate it into this script and keep it at two. Which I did.

P.S. I do agree that MixSets is great, but I want this to work without MixSets aswell

Ah, is another additional issue, because refilling by scroll wheel is a native issue, so we now also have a new issue besides of that.
But is fixed if use MixSets, right?

@The-Haxor Hey, try the updated version, I've found some code I could put

I was only able to test it briefly but it looks like the new functionality and the bug fix both work! The mod is like 200% better now! For me, at least.

I didn't know MixSets let you disable switch reloading. I have MixSets on the backlog of mods that I wanted to check out, it just had such a long list of changes that I had been putting it off because just thinking about fully configuring it gave me a headache.

Now there's only one small thing left that's bugging me. Although I think this is technically a problem with the vanilla game, it becomes more apparent when using the mod. If you reload and, while the animation is going, you see something you wanna shoot at and you aim at it, the reload gets cancelled and then plays a second time, which wastes times and throws me off. I did a quick search and I believe MixSets doesn't fix this.

Edit: actually, it looks like more things can cancel the reload animation. If you're crouched and not moving when you start reloading then moving or standing up can cancel it too. This game is kinda annoying.

I also noticed a thing that could be a bit more relevant. In vanilla, when you walk over a weapon on the ground, doing so still puts bullets in your mag so it removes the need for reloading in some cases.

I'm afraid I can't fix either of these, sadly

I think I found an actual bug now. When using the country rifle only the first shot works. This is the config I'm using:
DisabledOnSAMP = 1
DontReloadIfFull = 1
RealisticReload = 0
DisableScrollReload = 1
KeepNoAmmo = 1

Doesn't seem to happen without KeepNoAmmo.

This seems to be a bug with KeepNoAmmo itself - in particular, the asi file, which has no source code, so I can't tackle on it.
At least I think that's the case.

Unlucky. I guess I can just uninstall KeepNoAmmo then. Only wanted it for being able to empty the mag and switch quickly but I guess I'll live without it. Vanilla game animation cancels are more annoying

I updated the official download

@JuniorDjjr In the MixMods upload, you accidentally removed the [Controls] category, which breaks the mod
