MC BDS
by _375_
MC BDS automates walking routes, so a player can set a destination and let the character travel there on its own.
What it does
Once a destination is chosen, the pathfinding routine plans a path through the terrain in three dimensions. It works out costs for water, lava, soul sand and other blocks, and it splits long distances into chunk-sized sections so the route can cover wide areas. While the character moves, speed and facing are adjusted automatically, and the route is recalculated when a new obstacle appears.
Jumping, falling and climbing are decided by the routine as well, so gaps and steps are crossed without manual input. Edge-of-screen indicators point toward the next waypoint. Movement speed, the search range and other parameters can be adjusted in the settings.
The mod is released for Fabric and targets 1.21.1 only. A server running it needs every connecting player to have it too. The code is covered by All rights reserved, and the mod is not open source.
Key features
Route planning
The character follows a planned route to a chosen point without the player steering each step.
Terrain cost calculation
Each block type gets a movement cost, so water, lava and soul sand are weighted differently in the route.
Chunk-based long routes
Long-distance paths are built chunk by chunk, which keeps the search manageable over wide areas.
Obstacle avoidance
When the terrain changes or a blocking object appears, the path is recalculated during navigation.
Edge-of-screen indicators
Markers at the edge of the screen show the direction of the next waypoint while the character walks.
