A Godot 4.2 system for easily creating grids and path finding using AStar3D. GDExtension binaries for Windows, Linux, and MacOS(Unsigned).
These are the main features of the addon.
- Support for walking, flying, swimming, and climbing navigation.
- Easy to define box area for baking a [NavGrid].
- Saving bake data to avoid baking times.
- Custom C++ node to get_point_path with AStar3D on multiple threads.
These are the components of the addon.
- NavGrid: The main components for handling AStar3D generating and path finding.
- NavGridLink: Connects two different locations in a NavGrid.
- NavGridPathFinder: C++ component for get_point_path. Can execute this function on separate threads. Must be a child of a [NavGrid].
- NavGridAgent: Used to interface with [NavGrid] for subscribing to paths.
- subscribe_for_path(manager : NavGrid, start : Vector3, end : Vector3): Queues this [NavGridAgent] function to receive a path between 2 points from a [NavGrid].
- on_path_received(path : PackedVector3Array): Signal emitted when a path subscribed for has been received.
# Example of using some of the functions
func example():
nav_agent = get_node("CollisionShape3D/NavGridAgent")
nav_agent.on_path_received.connect(path_received)
nav_agent.subscribe_for_path(my_nav_grid, position, target.position)You can download the whole demo project and open it with Godot or download the "/astar3dnavgrid" folder from the "/addon" folder and put it in your "/addon" folder in your project. Make sure to enable the addon in your Project Settings.
