我如何显示动作脚本2.0中的随机三角形的坐标？ [英] how do i display the coordinates of a random triangle in actionscript 2.0?

问题描述

我想用坐标生成一个随机的三角形，它显示了动作脚本2.0中每个角落的弧线与闪光灯8.0。

>这看起来很像你的上一个问题（也很像这个其他问题），但这里有：

  import flash.geom.Point; 
 
函数randomPoint（）：Point {//返回舞台上的一个随机点
 var p：Point = new Point（Math.floor（Math.random（）*（Stage.width -300）），Math.floor（Math.random（）* Stage.height））; 
 return p; 
 
 
函数drawTriangle（mc：MovieClip，q1：Point，q2：Point，q3：Point）：Void {//通过3个点绘制一个三角形
 var stroke = 2; //三角形的行权重
 mc.lineStyle（stroke，0x000000，100，true，none，round，round）; 
 mc.moveTo（q1.x，q1.y）; 
 mc.lineTo（q2.x，q2.y）; 
 mc.lineTo（q3.x，q3.y）; 
 mc.lineTo（q1.x，q1.y）; 
 
 
函数drawCircle（target_mc：MovieClip，x：Number，y：Number）：void {
 //绘制一个以（x，y） b $ b var radius：Number = 18; 
 var k1：Number = Math.tan（Math.PI / 8）* radius; 
 var k2：Number = Math.sin（Math.PI / 4）* radius; 
 with（target_mc）{
 lineStyle（2，0xFF0000，100，true，none，round，round）; 
 moveTo（x + radius，y）; 
 curveTo（radius + x，k1 + y，k2 + x，k2 + y）; 
 curveTo（k1 + x，radius + y，x，radius + y）; 
 curveTo（-k1 + x，radius + y，-k2 + x，k2 + y）; 
 curveTo（-radius + x，k1 + y，-radius + x，y）; 
 curveTo（-radius + x，-k1 + y，-k2 + x，-k2 + y）; 
 curveTo（-k1 + x，-radius + y，x，-radius + y）; 
 curveTo（k1 + x，-radius + y，k2 + x，-k2 + y）; 
 curveTo（radius + x，-k1 + y，radius + x，y）; 
 
 
 
函数arcTriangle（）：MovieClip {//用角弧绘制三角形的主函数
 //创建一个新的movieclip t我们的三角形部分
 var depth = this.getNextHighestDepth（）; 
 var t：MovieClip = this.createEmptyMovieClip（t+ depth，depth）; 
 
 //定义3个随机点（作为t的属性存储）
 t.p1 = randomPoint（）; 
 t.p2 = randomPoint（）; 
 t.p3 = randomPoint（）; 
 
 //画一个三角形
 t.createEmptyMovieClip（triangle，0）; 
 drawTriangle（t.triangle，t.p1，t.p2，t.p3）; 
 
 //画一个实心的三角形作为掩码
 t.createEmptyMovieClip（mask，1）; 
 t.mask.beginFill（0xF0F0F0）; 
 drawTriangle（t.mask，t.p1，t.p2，t.p3）; 
 t.mask.endFill（）; 
 t.mask._alpha = 0; 
 
 //在每个角落添加一个红圈
 t.createEmptyMovieClip（arcHolder，2）; 
 drawCircle（t.arcHolder，t.p1.x，t.p1.y）; 
 drawCircle（t.arcHolder，t.p2.x，t.p2.y）; 
 drawCircle（t.arcHolder，t.p3.x，t.p3.y）; 
 
 //掩盖圆圈，只有内部弧线可见
 t.arcHolder.setMask（t.mask）; 
 
 //显示每个点的坐标（从舞台的左下角开始）
 t.createTextField（text1，3，t.p1.x，t.p1。 Y，300100）; 
 t.text1.text =（+ t.p1.x +，+（Stage.height-t.p1.y）+）; 
 t.createTextField（text2，4，t.p2.x，t.p2.y，300,100）; 
 t.text2.text =（+ t.p2.x +，+（Stage.height-t.p2.y）+）; 
 t.createTextField（text3，5，t.p3.x，t.p3.y，300,100）; 
 t.text3.text =（+ t.p3.x +，+（Stage.height-t.p3.y）+）; 
 
 return t; 
} 
 
 var myTriangle：MovieClip = arcTriangle（）; 
  

完成后应该看起来有点像这样：

I wanna generate a random triangle with coordinates, which shows the arcs of each corner in actionscript 2.0 with flash 8.0.

解决方案

This looks a lot like your previous question (also a lot like this other question), but here goes:

import flash.geom.Point;

function randomPoint():Point {  //return a random point on the stage
    var p:Point = new Point(Math.floor(Math.random()*(Stage.width-300)), Math.floor(Math.random()*Stage.height));
    return p;
}

function drawTriangle(mc:MovieClip, q1:Point, q2:Point, q3:Point):Void {//draws a triangle through 3 points
    var stroke=2;//line weight of triangle
    mc.lineStyle(stroke, 0x000000, 100, true, "none", "round", "round");
    mc.moveTo(q1.x, q1.y);
    mc.lineTo(q2.x, q2.y);
    mc.lineTo(q3.x, q3.y);
    mc.lineTo(q1.x, q1.y);
}

function drawCircle(target_mc:MovieClip, x:Number, y:Number):Void {
    //draws a red circle, centred on (x,y)
    var radius:Number=18;
    var k1:Number=Math.tan(Math.PI / 8) * radius;
    var k2:Number=Math.sin(Math.PI / 4) * radius;
    with (target_mc) {
        lineStyle(2, 0xFF0000, 100, true, "none", "round", "round");
        moveTo(x + radius, y);
        curveTo(radius + x, k1 + y, k2 + x, k2 + y);
        curveTo(k1 + x, radius + y, x, radius + y);
        curveTo(-k1 + x, radius+ y, -k2 + x, k2 + y);
        curveTo(-radius + x, k1 + y, -radius + x, y);
        curveTo(-radius + x, -k1 + y, -k2 + x, -k2 + y);
        curveTo(-k1 + x, -radius + y, x, -radius + y);
        curveTo(k1 + x, -radius + y, k2 + x, -k2 + y);
        curveTo(radius + x, -k1 + y, radius + x, y);
        }
}

function arcTriangle():MovieClip {  //main function to draw a triangle with corner arcs
    //make a new movieclip t which will hold our triangle parts
    var depth=this.getNextHighestDepth();
    var t:MovieClip = this.createEmptyMovieClip("t"+depth, depth);

    //define 3 random points (stored as properties of t)
    t.p1=randomPoint();
    t.p2=randomPoint();
    t.p3=randomPoint();

    //draw a triangle
    t.createEmptyMovieClip("triangle", 0);
    drawTriangle(t.triangle, t.p1, t.p2, t.p3);

    //draw a filled triangle to use as a mask
    t.createEmptyMovieClip("mask", 1);
    t.mask.beginFill(0xF0F0F0);
    drawTriangle(t.mask, t.p1, t.p2, t.p3);
    t.mask.endFill();
    t.mask._alpha=0;

    //add a red circle to each corner
    t.createEmptyMovieClip("arcHolder", 2);
    drawCircle(t.arcHolder,t.p1.x,t.p1.y);
    drawCircle(t.arcHolder,t.p2.x,t.p2.y);
    drawCircle(t.arcHolder,t.p3.x,t.p3.y);

    //mask the circles so only the interior arcs are visible
    t.arcHolder.setMask(t.mask);

    //show the coordinates (from bottom-left corner of the stage) for each point
    t.createTextField("text1",3,t.p1.x,t.p1.y,300,100);
    t.text1.text="("+t.p1.x+", "+(Stage.height-t.p1.y)+")";
    t.createTextField("text2",4,t.p2.x,t.p2.y,300,100);
    t.text2.text="("+t.p2.x+", "+(Stage.height-t.p2.y)+")";
    t.createTextField("text3",5,t.p3.x,t.p3.y,300,100);
    t.text3.text="("+t.p3.x+", "+(Stage.height-t.p3.y)+")";

    return t;
}

var myTriangle:MovieClip = arcTriangle();

It should look a bit like this when you're done:
