SteveL, I'll take this as far as I can from the perspective of alerting the AI and seeing how that impacts the current animation, but if it wanders into the territory of the improved 2.03 anims, I'll be pinging you for advice. |

Status: The AI is performing a PathSitTask, and is in the initial state of sitting down. Once he's sitting, he stays in the task, waiting for a timer to run out, at which point he'll stand up and continue pathing. If he's hit with an alert while in the act of sitting down (not yet sitting), he's asked to stand up before he can begin searching. The path sit task, still running, finds that he's gotten out of the sitting down part of the task, and asks him to start over, and sit down again. Then the search code says, "No, no, no, you have to be standing before you can begin searching, so stand up." And the path sit task says, "No, no, no, you're supposed to be sitting down, so sit down." This all used to work fine in 2.02, but we broke it somehow in 2.03. So I have to figure out why the path sit task is no longer being killed when the AI is asked to stand up so he can begin searching. I suspect that's the root cause of the problem. So this _might not_ have anything to do with the anim changes. We'll see. |

Cool, that's very clear. The "improvements" that caused the bugs in 2.03 were to do with syncing legs to torso. If wait states on the legs come into the picture, then this could well be 2.03-related. Searching got changed by both of us too of course. You did big search upgrades, and I did at least one tweak, I remember -- because searching wasn't releasing some anim wait state. I was planning to take a look too, but I'll stay out of your way while you're on the case. Please kick it to me if/when you put it down for a while. |

For 2.03, I fixed 0004054 by introducing states into the path sitting task. I _think_ this inadvertently introduced the bug we're seeing. Drawing the state diagrams now to see what needs to be tweaked in the 2.03 code to fix this problem while allowing 0004054 to remain fixed. |

When a PathSitTask was waiting to complete (in any of its stages), it wasn’t handling the situation where an alert elsewhere told the AI to GetUp() and start searching. This caused the sit task to tell the AI to sit back down again, and the search code to tell the AI to stand back up. Deadly embrace. Fix was to have the sit task recognize when the AI was getting up due to an alert, and terminate itself, leaving the search code free to take over. Rev. 6536: PathSitTask.cpp |
