1、关于路径跟随设置点形成路径控制物体运动:用过Torque3D的人都知道，在这个引擎中可以在编辑模式下设定路径然后AI就会按照这个路径运动，现在unity3D也可以啦分享给大家希望能有点帮助~总共3个文件把第一个个文件放在新建的gameobject上例如cube，然后creatempty创建空object作为splineparent，再创建4个或者多个sphere1，2，3，4作为它的子物体，然后将splineparent拖到这个代码varSplineParent:GameObject中，最后会看到cube按照sphere1到

2、4的顺序运动~JavaScript-SplineController.jsenumeOrientationMode{NODE=0,TANGENT}varSplineParent:GameObject;varDuration:float=10.0;varOrientationMode:eOrientationMode=eOrientationMode.NODE;varWrapMode:eWrapMode=eWrapMode.ONCE;varAutoStart:boolean=true;varAutoClose:boolean=

3、true;varHideOnExecute:boolean=true;privatevarmSplineInterp:SplineInterpolator=null;privatevarmTransforms:Array=null;@scriptAddComponentMenu("Splines/SplineController")functionOnDrawGizmos(){vartrans:Array=GetTransforms();if(trans.length<2)return;varinterp=newSpline

4、Interpolator();SetupSplineInterpolator(interp,trans);interp.StartInterpolation(null,false,WrapMode);varprevPos:Vector3=trans[0].position;for(c=1;c<=100;c++){varcurrTime:float=c*Duration/100.0;varcurrPos=interp.GetHermiteAtTime(currTime);varmag:float=(currPos-prevPo

5、s).magnitude*2.0;Gizmos.color=Color(mag,0.0,0.0,1.0);Gizmos.DrawLine(prevPos,currPos);prevPos=currPos;}}functionStart(){mSplineInterp=gameObject.AddComponent(SplineInterpolator);mTransforms=GetTransforms();if(HideOnExecute)DisableTransforms();if(AutoStart)FollowSpl

6、ine();}functionSetupSplineInterpolator(interp:SplineInterpolator,trans:Array):void{interp.Reset();if(AutoClose)varstep:float=Duration/trans.length;elsestep=Duration/(trans.length-1);for(varc:int=0;c

7、.AddPoint(trans[c].position,trans[c].rotation,step*c,Vector2(0.0,1.0));}elseif(OrientationMode==OrientationMode.TANGENT){if(c!=trans.length-1)varrot:Quaternion=Quaternion.LookRotation(trans[c+1].position-trans[c].position,trans[c].up);elseif(AutoClose)rot=Quaternio

8、n.LookRotation(trans[0].position-trans[c].position,trans[c].up);elserot=trans[c].rotation;interp.AddPoint(trans[c].position,rot,step*c,Vector2(0.
