Unity Animator.ResetTrigger (Parameter ‘Hash 0‘ does not exist)

for (int i = 0; i < animator.parameterCount; i++)
{
    animator.ResetTrigger(i);
}
animator.Play("Idle");

出现提示Warning：Parameter 'Hash 0' does not exist.

使用下面代码代替：

foreach (var parameter in animator.parameters)
{
    animator.ResetTrigger(parameter.name);
}
