Stop unit upon casting the ability

I'm creating a morphing hero with a twist:
He has the same hero abilities in both form with different effects.
There is a spell, that will heal allies in the human form and in animal form he charges towards an enemy.

I tried stopping the Hero on casting the ability ( I'm using vJASS, but I know this is possible to make in GUI too ) in the condition function or at the action function wit the event: "Begins casting an ability" but it seems that somehow he is still able to cast it :mad: The spell is based on Channel and it uses the wispharvest order string.
What should I do to properly stop the unit?

Since you understand vJass

JASS:
scope StopCast initializer I
    private function A takes nothing returns nothing
        call IssueImmediateOrder(GetSpellAbilityUnit(),"stop")
    endfunction

    //===========================================================================
    private function I takes nothing returns nothing
        local trigger g = CreateTrigger()
        local integer i = 0
        loop
            call TriggerRegisterPlayerUnitEvent(g,Player(i),EVENT_PLAYER_UNIT_SPELL_CHANNEL,null)
            set i = i+1
            exitwhen i == bj_MAX_PLAYER_SLOTS
        endloop
        call TriggerAddAction(g,function A)
    endfunction
endscope


or in GUI

Trigger:
  • StopCast
    • Events
      • Unit - A unit Begins channeling an ability
    • Conditions
    • Actions
      • Unit - Order (Casting unit) to Stop


But I suggest use the vJass one.

he don't need this -.- just use bj..

instead of Casting Unit/[ljass]GetSpellAbilityUnit()[/ljass] use Triggering Unit/[ljass]GetTriggerUnit()[/ljass]

EDIT: i think he don't want a channeling spell..... the Channel spell is just base, which is a good one..

begin cast an ability is more fast then start effect, but begin can and will bug, cuz you can just press the hotkey and then stop, the spell will cast but the cd and mana cost don't.

Yeah it's working, it seems, that my cooldown system interferes with the spell, but I don't understand because the system uses the event SPELL_FINISH. Hm that's strange

EDIT: Sry it uses ENDCAST

Sry for doublepost

I got it working using SPELL_EFFECT event, but now, it uses mana too :S even if I'm adding it back to the unit

    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
