作为输入的结构体必须命名为Input,这个结构体定义了一个float2的变量,float和vec都可以在之后加入一个2到4的数字,来表示被打包在一起的2到4个同类型数。例如下面: //Define a 2d vector variable vec2 coordinate; //Define a color variable float4 color; //Multiply out a color float3 multipliedColor = ...
usingUnityEngine;publicclassMover:MonoBehaviour {publicfloatspeed =5f;voidUpdate(){ transform.position += Vector3.forward * (speed * Time.deltaTime); } } In this example the script’s transform has its position added to every Update call - that is, every frame - in the forward direction. ...
Vector3.forward, Vector3.right, Vector3.up: 分别为(0,0,1) (1,0,0) (0,1,0)的缩写 在transform.Translate()中使用时: 若不标明坐标系,则为物体的局部坐标,即物体自身的前右上方向 若relativeTo=Space.World,则为世界坐标系,即世界坐标的前右上方向 ...
