Here is one of my spells for my hero

It's called "Destiny Bond" , just like Pokemon! : )

But in here, it bound the caster and the target together, and if one were to leave the 600 radius of the other it would be pull back and if 1 unit were to die it would deal damage to the unit that survive

The Damage part is okay

But I don't know how to detect who is the one who move out of the other range, I was planning on using If <Distance between (Caster) and (Target) is greater than 600> but I realize that by using this method If one unit move out of the Bond it would pull back both unit since it cannot detect who is the actual unit that move out of range

I switch to a more complex way of doing things, with a lot of Real and Point Variable :( This is my Trigger

Code:

        Trigger - Turn on Destiny Bond Lightning Effect <gen>

        If (All Conditions are True) then do (Then Actions) else do (Else Actions)

To put it in a Simple Way, The Trigger Store The Distance Variable before storing another one 0.01 second later

Then it would check if the Distance stored later is greater than the one stored before, if it is greater(The unit has move) it would Turn the Boolean True

Then finally it check that if the distance between the Caster and Target is greater than 600 then check that if the Boolean is true if both condition are met, the unit that trigger the Boolean will be pulled back

...This...is what I planned, but the unit is not pull back when It exits the range. Can anybody help me with this? :(

Wait 0.01 seconds doesn't work. I think the wait limit is 0.27 seconds or somewhere near there. Well, there isn't really a method to detect which unit moved out of range, because really, the two units can move away from each other and it would be pretty hard to tell which unit moved out of the 600 radius first.

A modification of your method would be viable. However, you'll need a periodic trigger that checks the X and Y of the unit every 0.03 seconds or so. Then, you can save the unit with a different X and Y value as the moved unit.

How does X and Y Integer works? Because I need to only detect units that are moving away to turn the Boolean On

If it only detect and turn On the boolean when a unit move then I fear if one bond unit run towards the other while it was running away the unit chasing the other would be repel back to Point of the Escaping unit offset by 600 range

Or if its too hard do you have any suggestion for this spell? anything similar is fine because I'm desperate D:

Thank you in Advance

Well, X and Y are basically coordinates. They're real. When you set a real variable, there should be an option "X of Point" and "Y of Point". Basically, you can easily check if there was a movement made by the unit using the X and Y values. Using distance between points every 0.01 seconds wouldn't be too efficient. Thus, just check if the X and Y values of the position of the units are different. If they are the same as the previous value, it means that they didn't move.

    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
