TODOs:

• replace b2.. (Box2D) types from source with UE types

  • b2Vec --> FVector
  • b2ParticleHandle --> void*

• find data or functions of engine for position mass and which handle

• check how constants are exposed from c++ to UE

• define interface for bodyhandles array and position array and mass array and how to store it efficiently in the setup of tree - [ ] maybe try niagara for oirganizing the particle system

• check if call in blueprint works with setup and step loop

• add third dimension

  • extend tree with upper and lower quads
  • check distance calkulation
  • check center off mass calculation

• check for dynamic radius

• check for dynamic mass

Feature ideas: Manipulation Tool (gun slingshot Osmos orbies ) Preview trace Escaped particles Fuse unfuse

Testing:

• check impulse preservation
• check null pointer
