Actionscript类:无法识别方法中的变量引用

Question

每当我尝试访问类方法中的变量时，Flash给出错误消息:访问未定义的变量

对于变量顶点、i、deltap等都是如此。据我所知，所有这些都应该为整个类定义。我错过了什么?

package 
{ 
    import flash.display.Shape;
    import flash.display.Graphics;
    import fl.motion.Color;
    public dynamic class Quadrilateral extends Shape {
        public var vertices:Array = new Array();
        public var endvertices:Array; 
        public var angle:Number;
        public var mycolor:Color;
        private var steps:Number;
        private var deltap:Array = new Array(4);
        private var i:Number;
        public function Quadrilateral(vertexlist, fillcolor, stepcount=100) {
            vertices = vertexlist;
            mycolor = fillcolor;
            steps = stepcount;
            drawme()
        }
        public static function setfinal(vertexlist) {
            endvertices = vertexlist;
            for (i=0;i<4;i++) {
                deltap[i] = (endvertices[i] - vertices[i])/100;
            }
        }
}

您错过了方法是static，这意味着您不能从内部访问非静态成员。

方法不应该是static
