当人物移动与离开指定区域后，自动播放相关动画

void OnTriggerEnter()

{

animation["AutoClose"].time = 0;

animation["AutoClose"].speed =1.0f;

animation.Play("AutoClose");

}

void OnTriggerExit()

{

animation["AutoClose"].time = animation["AutoClose"].clip.length;

animation["AutoClose"].speed = -1.0f;

animation.Play("AutoClose");

}

模型在UI中实现初始状态下360度自动旋转，手指拨动时，实现720度旋转

unity发不成web格式之后，原来的跳转都是覆盖原地址的，而这都不是我们想要的。看一下解决方法，利用网页的js来实现。 首先，在发布的网页里面加入一个函数。
function linkApp(url){window.open(url,"blank");}然后，在unity3d里通Application.ExternalCall来调用这个函数。
if(Application.isWebPlayer){
Application.ExternalCall("linkApp", "jianxiu/"+jianXiuURL[1]);
}else{
Application.OpenURL("jianxiu\\"+jianXiuURL[1]);
}

场景加载进度

void Start()

{

StartCoroutine(loadScene());

}

IEnumerator loadScene()

{

async = Application.LoadLevelAsync(x);

yield return async;

}

void Update()

{

//progress 的取值范围在0.1 - 1之间， 但是它不会等于1//也就是说progress可能是0.9的时候就直接进入新场景了

progress = (int)(async.progress *100);

}

unity发布web，单击链接新建页面打开链接，利用网页的js来实现。

在发布的网页里面加入一个函数。

function linkApp(url){window.open(url,"blank");}

然后，在unity3d里通Application.ExternalCall来调用这个函数。

if(Application.isWebPlayer)

{

Application.ExternalCall("linkApp", "jianxiu/"+jianXiuURL[1]);

}

else

{

Application.OpenURL("jianxiu\\"+jianXiuURL[1]);

}
