Unit Design

• Currently Implementation 3 types of block

  • Structural
  • Main Thruster(for orbit maneuver)
  • Side Thruster(for rotation adjestment)

• Move hard-coded block to data base

• Emission texture supported

• Multiple material supported

• Dynamic material supported

Orbit Mechanics

Stateful Physics Model

• prediection shift fixed
• implement object watch mechanism ：unwatch object is excluded by orbit prediction

Orbit Prediction

• General orbit section predication supported
• Distinct section color
• Planet-Hit prediction termination
• View Scaled orbit opacity
• Optimized by using Hermite Interpolation
• Orbit maneuver supported

Orbit Maneuver

• Physics-based Orientation Control
• Dynamic maneuver and animated maneuver system
• Orbit state system rewrited

Orbit Maneuver Algorithm

• Lambert solver implemented

Unit Control

• Input System Rewrited
• Test Spawn Impeachmented

Destruction

Operation guide:

• Right click and drag to move the camera
• Hold/release space to quickly toggle placement/selection mode
• In the selection mode, left-click to frame the object, and a circle will appear after the frame selection, which can be dragged to move the object
• Left click to place objects in placement mode
