Moving out of range 'before damage is dealt'?

[Sam117]

If a target of an attack moves out of range after being target, but before damage is dealt, do they still take the damage of the attack they were initially in range of?

 

For example. Iron man is targetted by an attack, and the dice are rolled, which results in 2 damage. Iron man then plays 'Fall back' which says he can advance s before damage is dealt. This short advance takes him out of range of the attack. Does Iron man still take the 2 damage?

Iron man would still take the damage in that scenario.
