All right. I'm tearing my hair out on this one. For days, I've been trying to get a character to stop attacking you and talk to you after a certain point, but nothing I do seems to work.
Basically, you get imprisoned, and you can talk to your guard, who'll let you out if you beat him in hand-to-hand combat. So, I devised this script :

Yes, I tried it with GetAV Health, I tried putting an OnKnockout block (he's essential), etc. Should I put a Yield command ? I doubt it'll work. I'm really lost here, so any help will be appreciated.

Oh, and there's a second problem : everytime he falls unconscious, he wakes up, attacks me, and there's now a bounty. Is it because he's a guard ?

I'm stumped

You don't need to change his aggression if it's only 5, which it should be if he's a guard. It might be better not to use a real guard for this because of the whole crime detection code.

Try using http://cs.elderscrolls.com/index.php?title=StopCombatAlarmOnActor. You'd have to pay off the bounty as well. That might be why he keeps attacking.

Thanks for replying, Andalay. But no, it doesn't work. The actor just keeps on hitting me, even when he's obviously at less than 20 health. I'll try tweaking his responsibilty and class next, as a last resort.

All right, new update : I've changed his class from Guard to Knight, and set a command to erase the PC's bounty at the start of the fight. This takes care of the getting up and having a new bounty problem. However, he still won't stop attacking at 20 health or less. So there's still that problem.

1. GetCurrentHealth isn't for checking actor health.
2. It's irrelevant to alter aggression or disposition as long as the actor's aggression is 5 or below.
3. For StopCombat, you don't need "player" at the end.

scn IBScript8short DoOncebegin Gamemode if (DoOnce == 1) RETURN elseif (DoOnce == 0) if ((JonasRef.GetActorValue Health / JonasRef.GetBaseActorValue Health) < 0.25) Player.StopCombatAlarmOnActor JonasRef.StopCombat JonasRef.StartConversation Player set DoOnce to 1 endIf endif  End

Hopefully your real code for this quest has stricter conditions on this section or else it'll trigger if the guard is hurt before he's supposed to be.

Dissentrix said he tried GetAV Health already. He wants combat to stop once the guard's health reaches 20, not a percentage.

Shroob is correct about getCurrentHealth - that's for your weapon not a character. Have a look at the http://cs.elderscrolls.com/index.php?title=Main_Page and the OBSE Docs. For the OBSE Docs, the version in your Oblivion directory is the latest.

Thanks, you two. I tried Shroob's method. He does stop fighting, but then just stands there and doesn't initiate conversation. And you can't talk to him, because he still seems to be in combat, despite not attacking. Is it a problem with the StartConversation command ? I've read if it isn't called more than once, it doesn't register.

The game implements StartConversation by creating an AI package that only runs once. If the character doesn't start the conversation soon enough, then the package has completed its run and it needs to be run again, so yes, it's usually best to have a condition and keep running startConversation until the NPC does indeed start the conversation. That's as easy as having the startConversation dependent on a variable and setting that variable in the Info result script.

It does register even if called only once, but it can be interrupted. Have you considered putting him and the player in a common faction marked "special combat"? Otherwise any other guards might try to help him.
