A Way to Detect Unit in Range of Any Unit from A Unit Group

Btw, I am not referring to a unit group but a boolean.

Pick every unit in group and check distance

Thanks for the help! However, checking distance still does not help much. Allow me to explain.

The spell I am working on drags units along with it and does different amounts of damage on impact and during pulling. I use a unit group to determine whether an enemy unit already contacted an missile and is being pulled.

The problem is that sometimes the missile might leave the target behind, and target remains in knockback group. If target remains in group, another missile that comes around won't deal "impact" damage to it.

One solution that I have in mind is latching the target on to the missile. How can I accomplish this?

A buff may work for what you need. When the damage is dealt by the missile, give it a buff. When it has the buff, remove it from the knockback group and then remove the buff. Then loop your actions for the duration of the trigger.

Not sure what trigger logic you are using though, so that may not be useful at all.
