Combining your units with ally/share map player

No there is no such thing,

And even if thy can program it, how can we control these unit ?

You can always trade units with your ally?

You can't 'share' units, and anyway, very difficult to implement.

Good replies. Obviously it would have to be somebody you can trust and give up control until convoy is at said place, or maybe. I guess the best answer is trade units then trade back.

Its not difficult to program that.

I had made a proposal a few weeks ago about that theme.

You only need one movement button "follow that army" to give your army the order to follow, stay and fight with the army you choose as your destination.

Armies to choose as a destination of the path does allready exist as an attack order. So I assume its the easiest of all to programm a follow order.

Ofcourse the army who is followed by the following army leads and has full controll of its path and attack orders. So this army has to wait or slow down its movementspeed activeley to make sure, that the follower can join.
