A-Star Grid Map

Node for managing an AStarGrid2D.

Connects to TileMapLayers and groups of dynamic colliders to automatically build the grid and set solid points.

Objective

Simplify interfacing with the AStarGrid2D.

I kept re-using this between projects and losing changes between versions, so I wanted to have one copy in a centralized place.

Installation

1. Go to the AssetLib tab.
2. Search for "A-Star Grid Map Plugin".
3. Click on the result to open the plugin details.
4. Click to Download.
5. Check that contents are getting installed to addons/ and there are no conflicts.
6. Click to Install.
7. Enable the plugin from the Project Settings > Plugins tab.

When enabled, the plugin will add the AStarGridMap2D node.

Usage

Add AStarGridMap2D to a scene and give it a region. Plug in a tilemap that should be treated as a wall, or the names of groups that have dynamic colliders, like doors or destructible obstacles.

Call get_world_path_avoiding_points() to get a path to a target.
