I'm trying to remake Darthfett's GetCenterUnit, basically allowed you to get the actual unit from the event Unit comes in range to x unit.

im trying to do this with Jesus' Event system, i have the idea down, but i have no idea how to do it

im assuming you can get which event was fired and attach data to events using the system so.. heres my idea

set event = Register unit comes within 500 range of unit 1.

then somehow attach data to the event, possibly in a struct?

then in the actions, i can do...

CenterUnit = Triggering Event[unit] (of course the syntax is wrong because i dont know it)

As far as I know, you can't get the triggering event, so you'll have to use dynamic triggers and attach the center unit to the trigger.

Ah, Sevion beat me...

Ran into a few problems though :-/ It's probably hella inefficient anyways.

Can't re-add anything unless I store the actual code variables... Which is impossible... Which means I can't "unregister" Which means you can't have more than one event per trigger... (kind of like how the original was)

Idk. I could probably end up completely emulating most of that if I spent more than an hour on this, but you had to go and play SC2 instead of helping me....

Idk... Maybe I'm thinking too much into this...

Bleh. This is flawed...

Currently, it doesn't work because I forgot to initialize the hashtable to null :(

And it doesn't support multiple center units atm... I need to fix it...

    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
