How can I make a spell aura only triggers when procs?

reflect the spell if the aura owner is in front of the caster where the spell comes from.

I have tried it with procs and made the if statement if(GetTarget()->isInFront(eventInfo.GetProcTarget()), but I could not find the correct way to make the aura only reflect when it procs.

My code so far:

[CODE]
class spell_custom_reflect : public SpellScriptLoader
{
public:
spell_custom_reflect() : SpellScriptLoader(“spell_custom_reflect”) { }

    class spell_custom_reflect_AuraScript : public AuraScript
    {
        PrepareAuraScript(spell_custom_reflect_AuraScript);

        bool CheckProc(ProcEventInfo& eventInfo)
        {
            return if(GetTarget()->isInFront(eventInfo.GetProcTarget()))
        }

        void HandleEffectProc(AuraEffect const* aurEff, ProcEventInfo& eventInfo)
        {
            // I want to reflect only when the aura effect procs.
        }

        void Register()
        {
            DoCheckProc += AuraCheckProcFn(spell_custom_reflect_AuraScript::CheckProc);
            OnEffectProc += AuraEffectProcFn(spell_custom_reflect_AuraScript::HandleEffectProc, EFFECT_0, SPELL_AURA_DUMMY);
        }
    };

    AuraScript* GetAuraScript() const
    {
        return new spell_custom_reflect_AuraScript();
    }

};[/CODE]
