Need help with battle system

I am creating a game where fights are one on one. You can still have a team but only one fights and after he is defeated, the battle is over. Please help me by showing me a plugin that will do this or showing me how to best program it.

I found a plugin that makes battles like Pokémon, where battles are one on one, but I haven't be able how to get the battle to end when you actor dies, because you still have some left.

I have merged your two posts for you. If you want to add something, just use the Edit button and add the additional information to your earlier post.

I don't think this will need a plugin. It would depend, though, on how you have set things up. How are you limiting the size of the battle party? Are all battles evented? Are they arena-type or do the enemies wander around the map as normal?
