Wind Walk issue

[Kajik]

Hello,
I have spell named "Stealth" based on Wind Walk. Let's say that hero will enter the Stealth and then he wants to use another ability. What I am trying to do is to check that spell conditions (in EVENT_UNIT_SPELL_CHANNEL) and if they are not met, stop his cast. But everytime, regardless of result it will kick him out of stealth. Is there any way to start the spell, check the conditions and then not cast it and remain in stealth? Any thoughts? Thanks.

EVENT_UNIT_SPELL_CAST is runned before the acutal spell often gets time to take effect I believe. Try have a trigger with that event, check the conditions and if true reset the unit's posistion. Perhaps you can even remove - give back his ability if it'd interrupt the effect.

SOLVED!
Instead of Wind Walk, I made an ability based on Bear Form (so I can shift in and out from stealth) and then add/remove ability named "Permanent Invisibility" with duration set to 0.0, so nothing (except situations when I want to) can kick me out of stealth.

function Stealth_Conditions takes nothing returns boolean
    return GetSpellAbilityId() == 'A009'    // Stealth (based from Bear Form)
endfunction

function Stealth_Actions takes nothing returns nothing
    if GetUnitAbilityLevel(GetTriggerUnit(),'Apiv') > 0 then    // Apiv - Permanent Invis.
        call UnitRemoveAbility(GetTriggerUnit(), 'Apiv')
    else
        call UnitAddAbility(GetTriggerUnit(), 'Apiv')
    endif
endfunction

//===========================================================================
function InitTrig_Stealth takes nothing returns nothing
    local trigger Stealth = CreateTrigger(  )
    call TriggerRegisterUnitEvent( Stealth, gg_unit_Hjai_0005, EVENT_UNIT_SPELL_CHANNEL )
    call TriggerAddCondition( Stealth, Condition( function Stealth_Conditions ) )
    call TriggerAddAction( Stealth, function Stealth_Actions )
endfunction

EDIT: There was some issue with bear form, nowadays I am using Manashield and order "manashieldon"/"manashieldoff" and it works perfectly. Just for those who would have simmilar problem.
