Godot-MVT

Standalone godot application that can ingest mapbox vector tiles from tile servers using tileJSON and save them as resources to be used in your projects. Uses C# and multi-threading so it's pretty quick. Resource generation from this repo requires C# and godot 3.x to run but the resources it generates will work in vanilla godot 3 or 4.

Provides godot resource abstractions for:

• MvtLayer
• MvtLayerTiles
• MvtTile
• MvtGeometry

Supports attributes.

Limitations

• Currently only ingests via HTTP.
• Tested with Martin tile server. Have problems with your MVT server? let me know.
• Due to fundamental limitations in godot's pooled memory, it can crash when building extremely large features. To prevent this split your features up or reduce complexity for larger tiles, and only process 1 layer at a time when importing. This is fixed in godot 4.

Render geometry in godot from vector tiles

var tile: MvtTile = load('res://data/tile/6/32-32.tres')
var geometry: MvtGeometry = tile.geometry
for g in geometry.size():
	var geom: Dictionary = geometry.get_index(g)
	print(geom.type) # Point, Line, Polygon, etc
	print(geom.properties) # Dictionary of supplied attributes
	var polygon := Polygon2D.new()
	polygon.set_polygon(geom.data)
	polygon.set_meta('gid', geom.properties.gid) # for example
	add_child(polygon) # voila!
