How do yu get battles in turns like in Fire Emblem

You think about it, be creative, and somehow get the units to be neutral while the other person/player is taking there turn. (give time to kill; Timers?)
doy... make p8 neutral (or anotha player)
When its not ur turn, make the person's unit owned by player 8. make timers for each turn.... make it so once the attack has been made, to make it stop. make p8 a non ally.... cmon.... be creative.
Faith and Destiny RPG has a really good turn-based system...
All that you have to do is set timers for each "turn" and make each yourself invulnerable for your turn. On the enemies' turn, make them invulnerable. Then, all you can do on your turn is run around in circles to avoid damage.
You should open an unprotected map that has this system, and look at how it works.
Good Luck.
