Graphics2D不会填充路径

I'm making a game and I want to draw mountains myself. I make the mountains using mid point displacement, store the points in an arraylist and then retrieve them in my Jpanel in my view. I draw other stuff like grass and g2 will fill them with colors but not my mountain. Here is the result:

我正在制作游戏,我想自己画山。我使用中点位移制作山脉,将点存储在一个arraylist中,然后在我的视图中将其检索到我的Jpanel中。我绘制其他东西,如草和g2将填充颜色,但不是我的山。结果如下:

Here's the code:

这是代码:

Point2D.Double start = new Point2D.Double(50, 400);
listePoints.add(start);

Point2D.Double end = new Point2D.Double(modele.getLargeur(), 400);
listePoints.add(end);       
this.maxIterations = 9;
int iterations = 0;
int minHeight = 5;
double nbrRandom = 10;
    while(iterations <  this.maxIterations) {
        iterations ++;
        int counter = 0;
        int size = listePoints.size()-1;
        int index = 0;
        while (compteur < size) {

            Point2D.Double point1 = listePoints.get(index);
            Point2D.Double point2 = listePoints.get(index+1);
            double milieu = Math.abs(point2.x - point1.x)/2;

            int orientation = Equations.randInt(1);
            switch(orientation ) {
            case 0: orientation  = -1;break;
            case 1: orientation  = 1;break;
            }


            Point2D.Double point3 = new Point2D.Double(point1.x+milieu,point1.y+(Equations.rand((nbrRandom+iterations = 0;
int minHeight)*orientation)));
            nbrRandom = nbrRandom /2;

            listePoints.add(index+1,point3);
            index +=2;
            counter++ ;
    }       

    }
    Point2D.Double point1 = new Point2D.Double(start.x,500);

    listePoints.add(0,point1);

    point1 = new Point2D.Double(end.x,500);

    listePoints.add(listePoints.size(),point1);

    point1 = new Point2D.Double(start.x,500);

    listePoints.add(listePoints.size(),point1);

/***************************** VIEW **/


        Path2D.Double path = new Path2D.Double(Path2D.Double.WIND_EVEN_ODD);    
        for (int j = 0;j < list.size()-1; j++) {


            Point2D.Double point1 = list.get(j);    
            Point2D.Double point2 =list.get(j+1);   


            path.moveTo(point1.x, point1.y);
            path.lineTo(point2.x, point2.y);

            path.closePath();
            g2.draw(path);
            g2.fill(path);
        }               
    }

If the question is "How do I fill the area below the jagged line with color?", the answer is:

如果问题是“如何填充锯齿线以下区域的颜色?”,答案是:

Join the end (presumably the right-hand side of the ArrayList of points) to the bottom of the container on the RHS.

将末尾(可能是点列表的右侧)加到RHS上容器的底部。

Join that point to the bottom LHS.

将这一点加入底层LHS。

Then call path.closePath();

然后调用path.closePath();

Or to put that another way, join the path end to the path start via the 'ground'.

或者换句话说,通过'ground'将路径结束连接到路径start。

If this explanation does not solve the problem for you (or if I guessed the question wrong), post an SSCCE.

如果这个解释没有为您解决问题(或者如果我猜错了),请发布SSCCE。
