Shatter meshes into shards in Godot 4.

This addon creates a polygon explosion effect similar to Sword Art Online.

Usage:

1. Add the addon to your game's addons folder.
2. Attach the ShardShatter.gd script to a node.
3. In the Editor group, set Target Path to the node you want to shatter (preferably a MeshInstance3D).
4. Press Shatter to shatter the target node!
5. Alternatively, call the shatter method on the node with the script.
