Struct AnimationIkChain 

pub struct AnimationIkChain {
    pub joints: Vec<String>,
    pub pole: [f32; 3],
    pub weight_parameter: String,
    pub foot_height: f32,
}

One two-bone IK chain, pinning the chain’s end joint (typically a foot) to the ground the physics scene finds beneath it.

joints names the chain root, middle, and end in the target skeleton – e.g. a hip, knee, and foot. The middle joint must be the direct child of the root and the end the direct child of the middle. Every frame the runtime probes straight down from the animated end joint; when a surface is within range, the chain bends so the end lands foot_height above it. Pinning pauses automatically while the character is airborne.

Fields

joints: Vec<String>

Names of the chain’s root, middle, and end joints, in order. Exactly three are required, matching the target skeleton’s joint names.

pole: [f32; 3]

Bend direction in mesh space: the middle joint bows toward this vector (a knee points forward, an elbow backward).

weight_parameter: String

Name of a declared graph parameter scaling the solve in [0, 1]; empty pins at full strength. Lets gameplay fade IK in and out.

foot_height: f32

Height the end joint rests above the probed surface, in mesh units (the sole-to-ankle offset for a foot).
