Is it compatible with Editor Extensions? I wanted to try testing this in the lab environment, but it doesn't seem like the equipments are doing anything there. They just cause the FPS/TPS to drop a lot whenever they are placed in an equipment grid, but the vitality doesn't increase the tank HP, and the pocket doesn't seem to increase the inventory size in either case.

(btw I think there should be a way to do the inventory thing without runtime hacks, as a built-in property of equipment in the base game, I think? I know this mod has a backpack equipment that works just like the space age toolbelt equipment, which works even without space age)

I have no idea if it's compatible with that mod. The features work fine for me... maybe some sort of mod interaction preventing it? Yes, there are probably other ways to do this now... this is an old mod.

I'll take a look at refactor when I get a chance.

Probably the FPS dropping is because I forgot to turn off debug so it's printing to a file. I'll fix that when I get a chance. It's not terribly efficient... if you put in 64 1x1 equipment pieces it's going to run the check 64 times. I get the jitter too when I insert a lot of them at once.

I don't think the vitality would increase tank HP. I think it only works on a player. https://asciireactor.com/factorio/adamo-equipment/-/blob/master/control.lua?ref_type=heads#L30

I noticed this was not working after the 0.3.3 bugfix as well. I ordered the operation wrong. That was probably what happened in your case. Sorry for the confusion... I was confused because even though this mod uses some silly control logic, it's been very reliable. Should be good now. And yeah, they did add an inventory bonus key to the prototype in 2.0, so I'll change it to use that eventually. No new keys for the other effects, though.
