When an AI gets stuck on an object that’s behind him, there’s no reason he shouldn’t be able to move forward. Temporarily make the object non-solid so it loses its grip on the AI, until the AI leaves. Then make the object solid again. Fixed in rev. 8743: State.cpp Entity.cpp Entity.h |

After alerting the AI |
|
|
Parkins is treadmilling but alerting him will release him from the situation. |
|
|
Hmm. This was replicated with capped FPS ( com_fixedTix 0 ). Uncapping FPS restored the fix... |
|
|
I can't use KODR2 or KODR3. I need a failure savegame prior to Parkins reaching the chair. |
|
|
Hmm... I again played with TDM on all "safe" settings (capped FPS, no multi-core) and noclipped right to the attic then waited for Parkins. On attempting to save as he was approaching the desk, the game crashed to desktop. |
|
|
SVN Rev 8752 The above "noclip" replication now saves with no error or crash. After saving, Parkins had no trouble leaving his seat and exiting the room. I will try a full replication to verify further. |
|
|
I cannot replicate the problem on rev 8752 with either safe or experimental settings. |
|
|
Note to self: Rather than checking sit/sleep completion flag once, try checking it until the AI is free of the chair/bed. Then clear it. There could be a timing issue between the setting and checking of the flag, and multiple checks should be able to deal with it. |
|
|
A thought: This seems to only happen when the AI is far out of sight.... "Interleaved Thinking" at play here? Edit: tdm_ai_opt_disable 0 seems to cure this issue in 2.08 Beta 7... Edit 2: More testing. I was able to reproduce it with this setting. Sorry |
|
|
Revs 8758, 8768, and 15950 round out the addition of checking AI who don't run into an obstacle after sitting/sleeping. |
|
|
Interleaved thinking won't be in play. The sitting/standing/sleeping anims need to stay in sync, so the AI gets to think every frame. |

At this point, since we have an OK from Spooks to correct the map, I'm going to stop working on the problem. Apparently it's way more complex (as is usually the case with pathfinding) than I originally imagined, and spending more and more time on it seems pointless. |
 |
Do you think the code you implemented should be removed/commented/disabled/frozen or left in working state? |
|
|
Removed. My ability to solve the continuous "one more example of failure" for this problem has been exhausted. I just wish I was able to reproduce the problem; that would have prevented the "spec" nature of the solution. |
 |
I can't start TDM SVN anymore, getting a crash with a blue window containing the following message: Error: file script\tdm_ai_base.script, line 1666: Unknown value "setGetUpTime" |
 |
Yeah, same here, looks like it was left in by accident when the other fixes were removed. Commenting out those 2 lines in the script file gets the game to load. Seeing as they are tagged with this bug report, fairly confident they can go. |
|
|
A repaired version of this mission is up on the repo. The state of SVN can be discussed in internal forums or (if we really need to) in another bug tracker. Closing. |
