ModMapLayer Class Referenceabstract

This class is used to facilitate easily drawing icons and other things over the map. Pylons and spawn/bed icons are examples of vanilla map layers. Use ModSystem.PreDrawMapIconOverlay(System.Collections.Generic.IReadOnlyList<IMapLayer>, MapOverlayDrawContext) to selectively hide vanilla layers if needed. More...
