Right, I need formula which would set height of my dummy missile depending on cliff level, to create straight shot. Like now it does like this...

It doesn't go straight. I need formula for height changing so it would go straightly (like a bullet), like this example.

One good fellow in THW said that some friend of his gave him this script which is used in Elimination Tournament (and such dummy missile movement I need as in that Elim Tournament).
JASS:
 z = Sin(Atan2(Z,maxDist))*DistanceTraveled


But I don't know where to put it in my trigger so my dummy actually changes height equal to that formula.

I also got few mini-questions:
1. What is "Sin"?
2. What is "Atan"?


*sigh* Some day I should start learning JASS, it would make world editor stuff making for me sooo easier xD

Sin=Sin of an angle, use a calculator to determine, or a unit Circle, this is in radians
Atan=This is basically the Degrees of the angle or 1/Sin/Cos x)

I've got no idea how to make the spell though x)

    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
