Detailed Description

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.

Member Function Documentation

◆ Draw()

abstract void Terraria.ModLoader.ModMapLayer.Draw	(	ref MapOverlayDrawContext	context,
		ref string	text
	)

pure virtual

This method is called when this MapLayer is to be drawn. Map layers are drawn after the map itself is drawn. Use MapOverlayDrawContext.Draw(Microsoft.Xna.Framework.Graphics.Texture2D, Microsoft.Xna.Framework.Vector2, Microsoft.Xna.Framework.Color, DataStructures.SpriteFrame, float, float, Terraria.UI.Alignment) as described in ExampleMod and in vanilla examples for full compatibility and simplicity of code.

Parameters

context	Contains the scaling and positional data of the map being drawn. You should use the MapOverlayDrawContext.Draw method for all drawing
text	The mouse hover text. Assign a value typically if the user is hovering over something you draw

Implements Terraria.Map.IMapLayer.
