If you look at all of the possible flags, the alliance bjs only set the ones that are used in the current alliance, meaning previous flags like neutral (which is only set in neutral flags) never get unset.

Anyways, this one probably unsets and sets all relevant flags. Obviously, the pro is that you don't have to code 5 lines of code every time you want to modify an alliance flag since this one already does that stuff for you. It also does 2 sided alliances only rather than 1 sided. Just makes scripts a bit easier to write and simpler to read when dealing with alliances =).

Explain those kinds of things in the system's description please. :)

Don't expect people to read all over your code just to understand what it really does and why we should use it.

Working with alliances is a pain, in my map all players started out as enemies and based on hero selection were allied, was a pain in the ass and code looked gross, I may consider using this instead.

Approved.

    Crazy how much 3d printing has come in the last few years. Sad that it's not as easily modifiable though
  • Varine Varine:
    I bought an Ender 3 during the pandemic and tinkered with it all the time. Just bought a Sovol, not as easy. I'm trying to make it use a different nozzle because I have a fuck ton of Volcanos, and they use what is basically a modified volcano that is just a smidge longer, and almost every part on this thing needs to be redone to make it work
  • Varine Varine:
    Luckily I have a 3d printer for that, I guess. But it's ridiculous. The regular volcanos are 21mm, these Sovol versions are about 23.5mm
  • Varine Varine:
    So, 2.5mm longer. But the thing that measures the bed is about 1.5mm above the nozzle, so if I swap it with a volcano then I'm 1mm behind it. So cool, new bracket to swap that, but THEN the fan shroud to direct air at the part is ALSO going to be .5mm to low, and so I need to redo that, but by doing that it is a little bit off where it should be blowing and it's throwing it at the heating block instead of the part, and fuck man
  • Varine Varine:
    I didn't realize they designed this entire thing to NOT be modded. I would have just got a fucking Bambu if I knew that, the whole point was I could fuck with this. And no one else makes shit for Sovol so I have to go through them, and they have... interesting pricing models. So I have a new extruder altogether that I'm taking apart and going to just design a whole new one to use my nozzles. Dumb design.
  • Varine Varine:
    Can't just buy a new heatblock, you need to get a whole hotend - so block, heater cartridge, thermistor, heatbreak, and nozzle. And they put this fucking paste in there so I can't take the thermistor or cartridge out with any ease, that's 30 dollars. Or you can get the whole extrudor with the direct driver AND that heatblock for like 50, but you still can't get any of it to come apart
  • Varine Varine:
    Partsbuilt has individual parts I found but they're expensive. I think I can get bits swapped around and make this work with generic shit though

    Heard Houston got hit pretty bad by storms last night. Hope all is well with TH.
