Ability which grants a ranged attack

[somedood]

In my map, i have melee heroes, but i want an ability which makes them become ranged at will, sort of like an autocast. I tried adding searing arrows or frost arrows, but it doesnt work with melee units. Then i tried making the units have a missile attack instead of melee, but at a very short attack range, then giving them searing arrows. That didnt work either.

Im not sure if there is an ability somewhere which will allow this, but i need to turn a melee unit into a ranged unit with an ability. Any help?

There is 2 ways I know of.

First - Create a spell made of the Bear form spell(night elf) and then create 2 units, 1 melee and 1 ranged (of the same type) then when he uses the bear form he turns into the ranged one, it can also be deactivated to make him melee again

second - Use triggers and upgrades

Lol

Use the rifleman upgrade ability using triggers (ex a unit learns a spell -> research the upgrade) and presto you have your range

You can do something complex with eat tree and some triggers
