public var isRendering:boolean=false; private var lastTime:float=0; private var curtTime:float=0; function Update() { isRendering=curtTime!=lastTime?true:false; lastTime=curtTime; } function OnWillRenderObject() { curtTime=Time.time; } 如此简单!如此巧妙!! 但是
JS计算两个点(经纬度)的距离 function getGreatCircleDistance(lat1, lng1, lat2, lng2) { var EARTH_RADIUS = 6378137.0; var PI = Math.PI; function getRad(d) { return d * PI / 180.0; } var radLat1 = getRad(lat1); var radLat2 = getRad(lat2); var a = radLat1 - radLat2;
