Hi Teo!
Thanks for your notes! I can give you some insight into some of your points.
The reason why AI ignore Deathwing fire breath is because we made a conscious decision for them to ignore it. Otherwise, AI agents would be constantly running away from Deathwing. This is due to our pathing system. It isn’t sophisticated enough to navigate around dangerous areas like how a human player would. Unfortunately, “fixing” pathfinding is not a trivial task as it would require substantial engineering efforts.
The AI think tree can check target states like unstoppable. It might be the case that Stitches isn’t checking that his intended hook target cannot actually be hooked. I will note this for investigation.
This was also a conscious decision we made so that agents prioritize their activities near objectives instead of engaging enemies while traveling to those objectives. It’s to prevent them from becoming too distracted. But maybe it’s too passive?
Yes, this is definitely something I am watching closely. It’s a tricky issue to solve because chasing can very easily get the agents killed. I think it’s best to be on the side of caution for now, though I am not opposed to pushing agents to be a little bit more aggressive in the future.
