Cast invisibility and then attack

[GM Arkwright]

When you have invisibility active, the spell ends when you attack a creature.

If I cast Vanish on myself, and then shoot a ranged touch spell at an enemy, will I gain the +2 bonus from being invisible before the spell ends?

[Weirdo]

Yes, you get the benefits of invisibility for the attack that breaks invisibility (including the +2 bonus and, if you were a rogue making a weapon attack, the ability to sneak attack).

Thanks.
