Unity3d 序列帧动画
序列帧动画的实质是uv信息的变化,理解Tiling(图片占得比例大小)和Offset(图片的偏移量)。 默认左下角offset为0 0 Tiling为小图/大图
代码如下:
public int rowNum ;
public int lineNum ;
public float iconwidth ;
public float iconheight ;
public int tileNum=6;
public float texWidth ;
public float texHeight ;
int achievementIndex=0;
float uWidth = 0;
float vHeight = 0;
// Use this for initialization
void Start () {
uWidth=iconwidth/texWidth;
vHeight=iconheight/texHeight;
InvokeRepeating("AnimationTexture",0,0.1f);
}
void AnimationTexture()
{
if(achievementIndex>tileNum)
{
achievementIndex=0;
}
int rowIndex=achievementIndex/rowNum;
int lineIndex=achievementIndex%lineNum;
float uNums=lineIndex*uWidth;
float vNums=1-rowIndex*vHeight;
Vector2 size=new Vector2(uWidth,vHeight);
renderer.material.SetTextureOffset("_MainTex",new Vector2(uNums,vNums));
renderer.material.SetTextureScale("_MainTex",size);
achievementIndex++;
}
