Mapwriter 2

The mod was originally created by Mapwriter. Original thread

Since he did not update the mod for a long time, I decided to continue the mod.

In game mini map mode (circular map mode enabled in map GUI options menu)

In game full screen GUI.

Zooming out to see the world.

Features:

• In game mini-map for multiplayer and singleplayer.
• Client side (server does not need to have the mod installed).
• The areas you explore are saved and can be viewed by scrolling or zooming the map, even when you are in a completely different part of the world.
• Full screen map GUI. Set waypoints by right clicking, pan map by click dragging, zoom with the mouse wheel.
• Rotating circular mini map mode. Can be enabled in the options GUI.
• Colours for blocks automatically generated from the block's texture.
• Support for custom texture packs.
• Support for blocks added by mods.
• Biomes now coloured appropriately.
• Entire map can be written to a PNG image.
• When in the Nether the mini map shows your effective location in the Overworld. This makes placing portals easier.
• Underground map mode (vastly improved in 2.0.14).
• All block colours configurable
