对于由自定义SKAction完成的运动，我想要一种比传统方程式创建的曲线更强大的缓动类型。如何使用SKKeyFrameSequence在SKAction中驱动动画？SKKeyFrameSequence创建我想要的曲线类型，如下所示:letsequence=SKKeyframeSequence(keyframeValues:[0.00,0.05,0.25,0.70,0.85,0.95,0.98,1.00],times:[0.00,0.10,0.15,0.20,0.23,0.28,0.50,1.00])sequence.interpolationMode=.splinestride(fro

SKKeyframeSequence上的Apple文档具有旨在创建渐变的简短示例代码:letcolorSequence=SKKeyframeSequence(keyframeValues:[SKColor.green,SKColor.yellow,SKColor.red,SKColor.blue],times:[0,0.25,0.5,1])colorSequence.interpolationMode=.linearstride(from:0,to:1,by:0.001).forEach{letcolor=colorSequence.sample(atTime:CGFloat($0))
