NavGrid System
PlayMaker → Addons → NavGrid
A 2D navigation system for grid-based movement, pathfinding, and procedural levels.
NavGrids can be baked in the editor or generated at runtime - ideal for roguelikes, mazes, and tile-based worlds.
Assets
Stores walkability, connectivity, and per-cell metadata used for movement and pathfinding.
Defines cost rules to apply to cells in a NavGrid.
Components
Bakes Tilemaps into NavGrid data at edit time, generating walkable cells and neighbor links.
A steering/pathfinding component that moves a GameObject on a NavGrid. Uses A* for pathfinding.
NavGrid Actions
Actions to build NavGrids at runtime.
Actions to move a GameObject on a NavGrid.
NavGridAgent Actions
Most commonly, you add a NavGridAgent to a GameObject that interacts with the NavGrid.
Configure its settings, then use actions to drive movement and decision-making.
Actions that use A* pathfinding to move to a target.
Actions that use turn decisions to steer on the NavGrid.
Actions for direct or player-driven movement on a NavGrid.
Actions for configuring the agent's settings at runtime.
