Balance exploration vs exploitation

G-Weight (Path Cost)

1Standard

0 (Ignore cost)5 (Balanced)10 (Cost priority)

Higher values prioritize shorter paths, lower values explore more freely.

H-Weight (Heuristic)

1Standard

0 (No guidance)5 (Balanced)10 (Goal focused)

Higher values focus more on reaching the goal, lower values explore uniformly.

Configure how the pathfinding algorithm handles diagonal movement between grid cells.

4-directional movement only

Diagonal blocked by adjacent walls

Diagonal allowed through corners

Diagonal Cost Multiplier

1.41×√2 (Euclidean)

Higher values make diagonal movement more expensive, encouraging more orthogonal paths.
