PathfindingLagFix

This modifies the Bracken AI (and others soon) to prevent it from causing a large stutter every 200ms in some situations, by spreading the load of checking hundreds of paths over multiple frames.

Details

• The EnemyAI.ChooseFarthestNodeFromPosition() function could end up checking 180+ nav mesh nodes for accessibility, if most or none of them were accessible. This could happen if the enemy was not on the nav mesh, or if the function call required line of sight and players were blocking most of the map from access.
  • This would occur for the Bracken if it spawned outside since it has no outside nodes, or if the bracken was in a dead end with a player watching the exit.
  • There may be other cases where this type of issue could occur, but currently this mod only patches the Bracken. Please report any cases to investigate with steps to reproduce the lag.

Version 1.2.1

• Removed some debug spam that would happen while a Snare Flea is retreating with no target players.

Version 1.2.0

• Prevent stutters caused by Snare Fleas finding a far location when there are no players to target.
  • This pathfinding would always happen if a Snare Flea spawned while no players are within the building.
  • More often in normal gameplay, it would occur if the Snare Flea fell off the playable area, since this would make all players untargetable, as well as make the search for a far location eventually fail.
  • NOTE: This may not cover all cases of lag caused by Snare Fleas. When they are running from a kill, they look for the nearest location that is accessible out of line of sight. If all line of sight checks fail, there may be stutters.

Version 1.1.0

• Fixed stutters that would happen when Spore Lizards run from the player.

Version 1.0.1

• Removed printing of the FlowermanAI.DoAIInterval() bytecode.

Version 1.0.0

• Fixed stutters that could occur when Brackens are retreating.
• Fixed stutters that always occur when Brackens spawn outside or are not on the nav mesh.
