Minimap

[pingwindev]

Visually

It should support different layers of data overlapping each one on top of the other, with some transparency in between. Minimum four to five layers.

From ground to top:

• [ ] 1. Terrain:
  • Water >> blue
  • Ground >> brown
• [ ] 2. Territory: Overlay of each player's area of control
• [ ] 3. Places of Interest: Anything (static?) in the world that has any relevance to the gameplay (e.g. all existing warehouses to trade with)
• [ ] 4. Units: All moving units (most dominantly ships, but ground units likewise)
• [ ] 5. Events: Icons for any occuring event (e.g. fire outbreak, "faction has just found settlement", etc.)

Gameplay-wise

Obviously it should be possible to map each point on the minimap to a specific point in the real world (at least roughly) so that it can be used to interact and navigate with.

Action pattern

	Left click	Double left click	Left click and hold	Right click
Terrain/Territory	Jump to location		Jump to location and drag camera in moving direction
Place of Interest	Select entity	Select and jump to entity location
Unit	Select entity	Select and jump to entity location
Event	Jump to location			Discard event (remove icon on minimap)
While in a unit/movement context:	Jump to location			Send unit to destination and act depending on layer (e.g. PoI=>Warehouse: dock/trade)

Additional Remarks

• [ ] The minimap should allow zooming for more precise selection and viewing.
