2D Physics Settings is under Scene Tab

2D World Settings

Enable Visualisation : Show collision shapes for the selected object.

World Collection : The collection containing world objects.

Gravity : Global gravity applied to the space.

Iterations : Iterations allow you to control the accuracy of the solver.

Steps per second : No of steps to simulate in a second, higher is better but slower.

Collision Bias : Determines how fast overlapping shapes are pushed apart. To improve stability, set this as high as you can without noticeable overlapping.

Collision Persistence : The number of frames the space keeps collision solutions around for. Helps prevent jittering contacts from getting worse. This defaults to 3.

Collision Slop : Amount of overlap between shapes that is allowed.

Damping : Amount of simple damping to apply to the space.

Start Frame : Start frame of simulation.

End Frame : End frame of simulation.

Bake Physics : Bake physics to keyframes.

Clear Bake : Clear baked keyframes.


Rigid Body settings is located in Physics Tab

2D Physics Object Settings

Mass : Mass of the shape

Moment of Inertia : Moment of inertia of the body.

Animated : Rigidbody is animated. i.e. take locations from the animation.

Velocity : The velocity of the body.

Angular Velocity: The angular velocity of the body in radians per second.

Calculate moment : From Shape will calculate the moment from all the shapes. From Body will calculate it manually from the values given.

Collision Shape : Circle, Poly, Segment (Line)

Density : The density of this shape.

Elasticity : Elasticity of the shape.

Start Point : The first endpoint of the segment.

End Point : The second endpoint of the segment.

Friction : Friction coefficient.

Surface Velocity : The surface velocity of the object. This value is only used when calculating friction, not resolving the collision.

Poly Shape

Shape from Curve : Get collision shape from curve.

Convex Hull : Calculate the collision shape from convex hull.

2D Physics Constraint

Type : Constraint Type.

First Object : The first of the two bodies constrained

Second Object : The second of the two bodies constrained

Anchor Point : Anchor Points on objects.

Collide Bodies : Ignores the collisions if this property is set to False on any constraint that connects the two bodies.

Error Bias : The percentage of joint error that remains unfixed after a second.

Max Bias : The maximum speed at which the constraint can apply error correction.

Max Force : The maximum force that the constraint can use to act on the two bodies.
