[Solved] Combat State in RPGs

[Knight of Arsford]

I'm thinking of adding a death mechanic wherein if a party member falls in battle, there are no means to revive them until the "battle" is over.

The combat state starts at the first encounter/aggro of an enemy, and will last until all the enemies in that blob is killed.

I've been playing around timers, is attacked events, and unit groups, but I still can't wrap my head around of implementing this kind of mechanic. I was thinking of just using good old fashioned resurrection stones in safe havens far from battle, but I want the deaths to be semi-permanent using the mechanic I described.

Also, if all party members are down, it's game over.

I'm hoping for ideas from anyone who's familiar with this. TIA!

There are two main approaches I can think of.

• Every time something combat related happens you restart the timer and disable reviving. Only if the timer expires do you enable reviving.
• When the blob of enemies spawns/engages you disable reviving. Periodically you check the status of the blob including proximity to party members. If the blob of units is all dead, or if the minimum distance between them and a living part member is outside their agro range then you enable reviving.

Thank you for the insight! I'll see what I can make of it.

I attached a map with a working system that could help you get started. It uses Bribe's Unit Indexer to keep track of the different Battle Groups (unit groups) that enemy units belongs to. Requires latest patch to open.

Thanks man. Wow, that's really detailed. I'll make use of this definitely.

No problem, I just uploaded a new version because the previous one was leaking Unit Groups in the Setup trigger.
