How to get angle from caster unit to picked unit in this case ?
JASS:
scope thunderclap initializer Init
globals
private constant integer SID = 'A000'
private constant integer SDID = 'A001'
private constant integer DID = 'h000'
private constant string SFX = "Abilities\\Weapons\\AncientProtectorMissile\\AncientProtectorMissile.mdl"
private constant string Order = "firebolt"
private constant real DamageBase = 100.
endglobals
private function Conditions takes nothing returns boolean
return GetSpellAbilityId() == SID
endfunction
//=====================
private function TJGetPPX takes real x, real dist, real angle returns real
return x + dist * Cos(angle * bj_DEGTORAD)
endfunction
private function TJGetPPY takes real y, real dist, real angle returns real
return y + dist * Sin(angle * bj_DEGTORAD)
endfunction

return bj_RADTODEG * Atan2(GetUnitY(B) - GetUnitY(A), GetUnitX(B) - GetUnitX(A))
endfunction
