Interact

Interact is a type of ability that allows unit to be used by other players than the owner.

Interact usually works on auto-cast, although it can be used as manually-cast ability. Casting this ability on a unit gives control of the casting unit to the target's unit controller. (e.g. an item shop cast this ability to grant control to the heroes standing nearby).

Fields

Apart from standard fields, this ability has just some specific flags.

• Share control - gives control to target unit, allowing use of abilities. If a Train ability is used through Interact and trains an item unit, the item is given in target unit's inventory.
• Share vision - gives the vision of the interacting unit with target unit's controller. (This is used for melee Xel'Naga towers)
• Exclusive - as long as one unit is targeted, no other can be. (needs confirmation: stops only autocast, it can still be manually changed)
