RigidBody2D Physics - Githubissues

List of Variables:

RigidBody Type ( Static, Kinematic, Dynamic )
~Position Vec2~ ( In Transform struct )
~Direction Vec2~ ( In Transform struct )
~Angle ( Essentially used to rotate the vector of a RigidBody)~ ( In Transform struct )
Mass
Velocity Vec2
AngularVelocity
LinearDamping
AngularDamping
Force Vec2 ( for position )
Torque ( for rotation if I'm not wrong ) "rotational force"
Awake ( To determine if the rigidbody is to be processed in a sense)
Previous Position
( To Consider ) Bitwise int to check which variables are active

Functions to Implement:

[x] Getters and Setters for all the variables ~- [ ] Apply LinearVelocity ( Changes the position )~ ~- [ ] Apply AngularVelocity ( Changes the rotation )~ ~- [ ] Calculate Direction Vector from Angle / Calculate Angle from Direction Vector~ ~- [ ] Apply LinearDamping ( Forces acting against RigidBody, reducing its Force like friction, air resistance etc.)~ ~- [ ] Apply RotationalDamping ( Forces acing against RigidBody, reducing its Toque )~
[x] Apply Force ( Adds on to the existing force on the RigidBody )
[x] Apply Torque ( Adds on to existing torque on the RigidBody )
[x] Apply Impulse (For dashing etc)

Physics Pre-Testing using Alpha Engine for Visuals

Input Force = 5000.f for all directions
Linear Drag = -2.5f
Mass = 10.f
Notes:
- Rotational Velocity has a simple implementation without forces, linear velocity is affected by forces to some extent
- Requires testing in the custom engine!!!

Notes:

**Did a quick and dirty position update in DrawDebug to get visuals for this test
Force: 5000.f
Mass: 10.f
Linear Drag: -2.f
Impulse/Sprint: 1000.f
Negligence ( hard coded ): 2.f
RigidBodyType: Dynamic
