Struct bevy::prelude::VariableCurve

pub struct VariableCurve {
    pub keyframe_timestamps: Vec<f32>,
    pub keyframes: Keyframes,
    pub interpolation: Interpolation,
}

Describes how an attribute of a Transform or MorphWeights should be animated.

keyframe_timestamps and keyframes should have the same length.

Fields

keyframe_timestamps: Vec<f32>

Timestamp for each of the keyframes.

keyframes: Keyframes

List of the keyframes.

The representation will depend on the interpolation type of this curve:

• for Interpolation::Step and Interpolation::Linear, each keyframe is a single value
• for Interpolation::CubicSpline, each keyframe is made of three values for tangent_in, keyframe_value and tangent_out

interpolation: Interpolation

Interpolation method to use between keyframes.

Implementations

impl VariableCurve

pub fn find_current_keyframe(&self, seek_time: f32) -> Option<usize>

Find the index of the keyframe at or before the current time.

Returns None if the curve is finished or not yet started. To be more precise, this returns None if the frame is at or past the last keyframe: we cannot get the next keyframe to interpolate to in that case.
