Rename the variable delta to something more descriptive in the client.

The game loop needs to run on the server and update the server state at a given interval.
Each run of the game logic loop is referred to as a Tick.

• Use an ECS to run systems on each tick
• Units have a 2d position, velocity and target destination.
• Units has a unit type
• Entities must have a globally unique id
• Units can have a target destination, that is removed once they get to it.
• A system for velocity -> position
• A system for target destination -> velocity
• A unit that stands still (velocity 0) must have its velocity removed.
• Input from users must be stored, and applied on each tick
• User input must not be blocked by the run of the tick
• Getting current server state must return the newest server state.
• If the tick is running, requests for game state can wait for the newest result (or return the old if possible).

Create MVP Universe enviroment

• Star/Galaxy background (might be static as a start)
• Snap points / Grid for placing structures

Placement of structure

• Create service class for user inputs
• Create system for placing structures (spacestation)
• Create / Find placeholder 3d model of space station
• Show Ghost image of structure before placement
• Place Tempoary structure until validated by server and make it permenent when server replies with UnitCreated
• Prevent placement of structures on allready ocupied areas
