iTween的一个潜在BUG

2.0.5版本

GenerateMoveToPathTargets

if(tweenArguments.Contains("speed"))

{        float distance = PathLength(vector3s);time = distance/(float)tweenArguments["speed"];

}

vector3s 是已经补齐前后控制点的，但是PathLength中又会再补一次。造成BUG

google code上已经有人提出这个问题
Issue 75:GenerateMoveToPathTargets + "speed" argument issue

答复是：

Actually it looks like suppliedPath will not do as it does not account for plotStart set to true, so you could either create a new array to hold that as well or pass offset and length arguments to PathLength to skip the start/end nodes

正确的改法应该是把vector3s去除头尾再传递给PathLength
