Dynamic Bone Chain

Bone Chain Setup

• Root Bones: List of transforms where each dynamic chain starts.
• Excluded Bones: Bones (and their children) to exclude from simulation.
• Root Bone Offset: Rotation offset applied to the root bone (degrees).

Main Physics Properties

• Stiffness: How rigid the chain is (0 = floppy, 1 = rigid).
• Elasticity: How quickly bones return to rest pose.
• Damping: How quickly movement slows down.

Force Properties

• Gravity Strength: How strongly gravity affects the bones.
• Inertia: How strongly bones maintain momentum.
• Parent Influence: How strongly child bones follow their parents.
• Tip Heaviness: Makes the tips of chains heavier/more reactive.

Movement Limits

• Maximum Angles: Maximum bend angles allowed (degrees).

Sine Wave Animation

• Enable Sine Animation: Adds automatic wave-like motion.
• Wave Speed: Frequency of the sine wave (cycles/sec).
• Wave Size: Size of the wave motion (degrees).
• Main Motion Axis: Primary axis for the wave motion.
• Secondary Motion: Amount of motion on the secondary axis.
• Phase Offset: Offset between primary and secondary motion (degrees).

Random Variation

• Randomness: Random variation in the wave animation.
• Variation Speed: How quickly random variations occur.

Simulation Settings

• Auto Update: Enable/disable automatic updates.
• Use Fixed Update: Update in FixedUpdate instead of LateUpdate.
• Time Scale: Simulation speed multiplier.
• Scale Multiplier: Global scaling factor for all forces and movements.
• Solver Iterations: Number of constraint solving iterations (higher = more accurate but slower).

Animation Integration

• Animation Priority: Priority when multiple animations affect the same bones.

Collision Settings (Experimental)

• Enable Collisions: Allows bones to collide with scene colliders.
• Collision Layers: Which layers to check for collisions.
• Collision Shape: Shape to use for bone collisions (Sphere, Capsule, MultipleSpheres).
• Collision Size: Radius of collision shapes.
• Sphere Count: Number of spheres to use for collision (if MultipleSpheres).
• Bounciness: How much bones bounce off surfaces.
• Friction: How much bones slow down when sliding on surfaces.

Note: Collision system is experimental and may not work perfectly in all cases.

Debug Visualization

• Show Visuals: Display debug visuals in the scene view.
• Debug Color: Color for debug visualizations.

Actions

• Initialize Chain: Set up the bone chain hierarchy.
• Restore Bind Pose: Return bones to their original positions.
• Reset Simulation: Reset the simulation state.
• Capture Current Pose: Store the current pose as the rest pose.
