Pathfinding/Alpha release notes

Restrictions

The initial release of the pathfinding LSL is available only on the Aditi test grid on the following regions:

Known issues

• Saving scripts sometimes doesn't work - post save the character is frozen. Picking up the object with script running and rezzing makes the character activate.
• Can't set an offset to the vertical height that the object hovers at, or make it lower so that it appears to hug the ground, or move through the ground. In other works pathing is only script modifiable in X and Y coordinates, not Z, but pathing functions in all three coordinates, albeit with Z hugging the terrain or objects it is passing over.
• When creating a fleeing script, has to be set to flee one AV at a time, ideally needs to be possible to flee everyone.
• Replacing an existing script doesn't stop behaviour, in the same way as particles and hover text, use llExecPathingCmd(PATH_CMD_STOP, [])
• Occasionally a script fails with no explanation - no path related elements work but pathing silently fails. Putting the same script contents in another prim works perfectly.
• Getting occasional “database content cannot be loaded” error when reopening an existing script.
• Can't move object 'wandering of cube of wandering +1' to { 73.4555, 143.077, 22.443 } in region PathDev2 because of an unknown reason. [4194304]
  • Let me know if you figure out what triggers this. I saw some cases, in the server logs, and they seemed to indicate something about full parcels which lead to objects going deeply underground; so far, I don't know how to reproduce this error. --maestro
• If a targeted agent flies the agent becomes invisible to path script.
  • This doesn't seem to be always valid: I can be flying near the ground and still be followed. If I fly out of the vertical bounds of the path volume it then loses me.
