[JASS] How do I change the selection scale of a unit with a different skin Id

[FaceJaraxxus]

Hello again! With two functions I am manipulating the unit skin and associated sizes to sell that it's a different unit. However, the selection scale doesn't wanna play fair.

Warlock uses ability > transforms into a large demon. The selection scale is visually small, but when mouse dragging to select it's large for a brief moment. Then, when the Demon (warlock) uses the ability to revert the transformation, the selection scale is larger than the Warlock's original selections scale. Currently in the code I don't have a selection scale change after the skin changes, and that's because it just didn't do anything.

And yes, the code isn't optimized.

globals
     real warlockUnitScale
    real warlockUnitSelection
    integer warlockSkinId
endglobals

function Demon_To_Warlock takes nothing returns nothing
    if udg_warlockIsDemon == true then
    set udg_WarlockMana = 0
    call DisableTrigger( gg_trg_WarlockDrain )
    call SetUnitAnimation( udg_WarlockHero, "spell channel" )
    call PauseUnitBJ( true, udg_WarlockHero )
    call AddSpecialEffectTargetUnitBJ( "origin", udg_WarlockHero, "Desecrate_JFI.mdx" )

    call DestroyEffectBJ( udg_WarlockHand1 )
    call DestroyEffectBJ( udg_WarlockHand2 )

    call UnitRemoveAbilityBJ( 'A0C4', udg_WarlockHero )
    call UnitRemoveAbilityBJ( 'A0C5', udg_WarlockHero )

    if GetUnitTypeId(udg_WarlockHero) == 'N056' then
        call SetUnitMoveSpeed( udg_WarlockHero, 270.00 )
    else
        call SetUnitMoveSpeed( udg_WarlockHero, 290.00 )
    endif
    call SetUnitInvulnerable( udg_WarlockHero, true )
    call PolledWait( 1.90 )

    call SetUnitAnimation( udg_WarlockHero, "spell slam" )
    call BlzSetUnitSkin( udg_WarlockHero, warlockSkinId )

    call SetUnitVertexColorBJ( udg_WarlockHero, 100.0, 100.00, 100.00, 0 )

    set udg_WarlockHero = null
    set udg_warlockIsDemon = false
endif

        set udg_WarlockHand3 = GetLastCreatedEffectBJ()
        call SetUnitAnimation(udg_WarlockHero,"birth")

        call BlzSetUnitDiceNumber( udg_WarlockHero, 6, 0 )

        call UnitAddAbilityBJ( 'A0C4', udg_WarlockHero )
        call UnitAddAbilityBJ( 'A0C5', udg_WarlockHero )
        call SetUnitMoveSpeed( udg_WarlockHero, 200.00 )
endfunction

I have tried solutions such as

call BlzSetUnitRealField(udg_WarlockHero, UNIT_RF_SELECTION_SCALE, warlockUnitSelection)

And having debugged the real values, I have noticed that the fields do change. Just not the visual indicator. Any ideas on what to try next?

It seems like updating UNIT_RF_SELECTION_SCALE only updates the health/mana bar scale and a few other indicators (e.g. target indicator)--but doesn't seem to affect the actual selection circle.

I think your best bet is to use morphing. You can either use bear form/metamorphosis for your ability directly, or if you need to update this passively (i.e. you want to trigger it without the user taking any action), you can follow this tutorial: Hero passive transformation
