Rust value animation curve

anim_curve

Rust value animation curve

• 动画曲线包含

  • 关键帧帧数据
  • 曲线进度计算器

• 曲线进度数据类型可选 f32 或 f64, 默认为 f32

• 曲线类型

  • 关键帧插值
    • 线性插值
    • CubicSplice 插值
  • CubicBezier 插值曲线
  • 类Unity的 MinMaxCurve Hermit插值曲线

Example

• 创建线性缓动曲线

    let curve = FrameCurve::curve_easing(0.0, 1.0, frame_count as FrameIndex, frame_count, EEasingMode::None);

• 创建关键帧线性插值曲线

    let mut curve = FrameCurve::curve_frame_values(60);
    FrameCurve::curve_frame_values_frame(&mut curve, 0, 0.0);
    FrameCurve::curve_frame_values_frame(&mut curve, 15 as FrameIndex, 1.0);
    FrameCurve::curve_frame_values_frame(&mut curve, 30 as FrameIndex, 3.0);
    FrameCurve::curve_frame_values_frame(&mut curve, 60 as FrameIndex, 4.0);

    // 创建步进进度计算器
    let amountcalc = AnimationAmountCalc::from_steps(1, EStepMode::JumpStart);
    let val = curve.interple(i as KeyFrameCurveValue / 60., &amountcalc);

• 创建MinMaxCurve曲线

    let mut curve = FrameCurve::curve_minmax_curve(0.0, 1.0, 60);
    FrameCurve::curve_minmax_curve_frame(&mut curve, 0, 0.0, 2.0, 2.0);
    FrameCurve::curve_minmax_curve_frame(&mut curve, (frame_count/2) as FrameIndex, 0.5, 0.0, 0.0);
    FrameCurve::curve_minmax_curve_frame(&mut curve, frame_count as FrameIndex, 1.0, 2.0, 2.0);
