propertiesproperties问题1：如何实现物体的逐步放大？？

IEnumeratormyCoroutine()

{for(floatf=1f;f<3.0f;f+=0.4f)

{Vector3v=newVector3(f,f,f);transform.localScale=v;print(transform.lossyScale);yieldreturnnewWaitForSeconds(3);

}

}localPosition游戏对象在局部坐标中的位置，如果无父级对象则和transform.position一样。如果父级对象有子对象如下：cube0->cube1->cube2cube1和cube2的localPosition增加一个单位，其position是否也是增加一个单位？？？如果localScale=1,localToWorldMatrix父节点position=newVector3(0,0,1);子节点localPosition=newVector3(0,0,1);子节点的position=0,0,2????transform.localToWorldMatrix.MultipyPoint(localPosition)--(0,0,1)

transform.localPosition=newVector3(0f,0f,0.0f);print(transform.localToWorldMatrix.MultiplyPoint(newVector3(0f,0f,1.0f)));

???????transform.localPosition=newVector3(0f,0f,1.0f);print(transform.localToWorldMatrix.MultiplyPoint(newVector3(0f,0f,1.0f)));

?????????worldToLocalMatrix

//游戏对象的父级对象的position=(0,0,1)//如果本游戏对象的position=(0,0,1)//下面给出该游戏对象的localPositionprint(transform.worldToLocalMatrix.MultiplyPoint(newVector3(0f,0f,1.0f)));//（0，0，0）print(transform.InverseTransformPoint(newVector3(0,0,1)));//(0,0,0)publicmethodspublic

用unity的简单模型做一个卡通直升机，有旋转翼，用鼠标或键盘控制飞机的飞行，旋转翼能自动旋转，鼠标或键盘控制转速。下
