Unity3D实现虚拟按钮控制人物移动效果

Unity3D实现虚拟按钮控制⼈物移动效果本⽂为⼤家分享了Unity3D实现虚拟按钮控制⼈物移动的具体代码，供⼤家参考，具体内容如下创建Image的UI组件，在Image下新建⼀个Button按钮。在Image和Button上拖进Sprite图⽚在Button按钮上挂载该脚本usingSystem.Collections;usingUnityEngine;usingUnityEngine.EventSystems;usingUnityEngine.UI;publicclassMyJoystick:MonoBehaviour,IPointerDownHandler,IPointerUpHandler{publicCanvascanvas;publicstaticfloath;//h和v的值传回给player脚本，使得物体移动publicstaticfloatv;privateboolisPress=false;//Button按钮是否按下privateVector2touchPos=Vector2.zero;//按下的位置voidUpdate(){if(isPress){RectTransformUtility.ScreenPointToLocalPointInRectangle(canvas.transformasRectTransform,Input.mousePosition,null,outtouchPos);//根据Canvas和Image的Rectransform位置相减得出touchPos+=newVector2(427,299);floatdistance=Vector2.Distance(Vector2.zero,touchPos);if(distance>52){//限制Button不能超出Image位置（两者位置相减得出52）touchPos=touchPos.normalized*52;transform.localPosition=touchPos;}else{transform.localPosition=touchPos;}h=touchPos.x/52;v=touchPos.y/52;}}//⿏标按下时触发publicvoidOnPointerDown(PointerEventDataeventData){isPress=true;}//⿏标按键弹起时触发publicvoidOnPointerUp(PointerEventDataeventData){isPress=false;transform.localPosition=Vector3.zero;}}在玩家⾝上挂载控制玩家移动的脚本usingSystem.Collections;usingSystem.Collections.Generic;usingUnityEngine;publicclassPlayerMove:MonoBehaviour{publicfloatspeed=0.1f;privatefloath=0;privatefloatv=0;voidUpdate(){//⾸先检测虚拟按键有没有移动，没有再选择键盘输⼊if(Mathf.Abs(MyJoystick.h)>0||Mathf.Abs(MyJoystick.v)>0){h=MyJoystick.h;v=MyJoystick.v;}else{h=Input.GetAxis("Horizontal");v=Input.GetAxis("Vertical");}//玩家位置移动if(Mathf.Abs(h)>0.1||Mathf.Abs(v)>0.1){Vector3targetDir=newVector3(h,0,v);transform.position+=targetDir*speed;transform.LookAt(
