2, create player player to use cube instead and create sub object under Cube head position default value zero, use: Player information display location.

3, use Ngui to create player information follow, structure as follows:

4, Paste code: NewBehaviourScript.cs Hanging on the Maincamera

usingUnityengine;usingSystem.Collections; Public classNewbehaviourscript:monobehaviour {//role     PublicTransform Cube; //to the age lead to move the information blood bar, name     PublicTransform UI; //the distance between the default blood bar and the camera    Private floatFomat; //role Head Position    PrivateTransform Head; voidStart () {//find the character head pointHead = Cube.find ("Head"); //calculate the distance of the default blood barFomat =vector3.distance (head.position,camera.main.transform.position);    Debug.Log (Fomat); }        voidUpdate () {//Here you can judge if the position has not changed the class no longer assigns a value        floatNewfomat = Fomat/vector3.distance (head.position,camera.main.transform.position); Ui.position=Worldtoui (head.position); //calculate the scale of the blood barUi.localscale = Vector3.one *Newfomat; //test code move role        if(Input.getkey (KEYCODE.W)) cube.translate (Vector3.forward); if(Input.getkey (KEYCODE.S)) cube.translate (Vector3.back); if(Input.getkeydown (KEYCODE.A)) cube.translate (Vector3.left); if(Input.getkeydown (KEYCODE.D)) cube.translate (vector3.right); }    //3D coordinates converted to 2D coordinates on the Ngui screen     Public StaticVector3 Worldtoui (Vector3 point) {Vector3 pt=Camera.main.WorldToScreenPoint (point); //Uicamera.currentcamerVector3 FF =UICamera.currentCamera.ScreenToWorldPoint (PT); //the z-axis of the UI is 0Ff.z =0; returnFF; }}

5, another script Cube.csgua hangs on the player

usingUnityengine;usingSystem.Collections; Public classCube:monobehaviour { PublicGameobject FG; PrivateGameobject Sprite;  Publicgameobject harm;  PublicUILabel HP; //Use this for initialization    voidStart () {harm. SetActive (false); Hp.text="hp:100/100"; }        //Update is called once per frame    voidUpdate () {}voidOnMouseDown () {if(FG. Getcomponent<uisprite> () .fillamount>0) {FG. Getcomponent<UISprite> (). Fillamount-=0.1f; Harm. SetActive (true); Hp.text= ((int) (FG. Getcomponent<uisprite> (). fillamount* -)). ToString () +"/100"; } Debug.Log (FG. Getcomponent<UISprite>(). Fillamount); }    voidOnMouseUp () {harm. SetActive (false); }}
