Java mousePress不能正常工作

Question

我知道有很多关于mousePressed不能正常工作的帖子，但我还没有找到我的问题的答案。我写了一个程序，只是为了好玩和体验，但我在使用Robot类的mousePressed方法时遇到了问题。这是我的代码：

//Program to say "Hi!" by moving cursor
//https://sketch.io/sketchpad/
//Open up sketchpad, run OCursor, then click on the sketchpad

import java.awt.*;
import javax.swing.*;
import java.awt.event.InputEvent;

public class OCursor {
    public static void main(String[] args) {
        try {
            // These are the screen coordinates
            int cd1 = 400;
            int cd2 = 600;
            int cd3 = 700;
            int cd4 = 750;
            int cd5 = 800;
            int cd6 = 1000;
            int cd7 = 1100;
            int cd8 = 1200;
            int cd9 = 1400;

            // This is the time and amount of steps
            int t = 300, n = 5000;

            // 5 second delay to click on sketchpad
            Robot robot = new Robot();
            robot.delay(5000);

            // Move and click the cursor
            robot.mouseMove(cd2, cd5);
            robot.mousePress(InputEvent.BUTTON1_MASK);
            mouseGlide(cd2, cd5, cd2, cd1, t, n);
            mouseGlide(cd2, cd2, cd5, cd2, t, n);
            mouseGlide(cd5, cd5, cd5, cd1, t, n);
            robot.mouseRelease(InputEvent.BUTTON1_MASK);
            robot.delay(100);

            Robot robot2 = new Robot();
            robot2.mouseMove(cd6, cd1);
            robot2.mousePress(InputEvent.BUTTON1_MASK);
            mouseGlide(cd6, cd1, cd8, cd1, t, n);
            mouseGlide(cd7, cd1, cd7, cd5, t, n);
            mouseGlide(cd6, cd5, cd8, cd5, t, n);
            robot2.mouseRelease(InputEvent.BUTTON1_MASK);
            robot2.delay(100); 

            Robot robot3 = new Robot();
            robot3.mouseMove(cd9, cd5);
            robot3.mousePress(InputEvent.BUTTON1_MASK);
            mouseGlide(cd9, cd5, cd9, cd4, t, n);
            robot3.mouseRelease(InputEvent.BUTTON1_MASK);
            robot3.delay(100);
            robot3.mouseMove(cd9, cd3);
            robot3.mousePress(InputEvent.BUTTON1_MASK);
            mouseGlide(cd9, cd3, cd9, cd1, t, n);
            robot3.mouseRelease(InputEvent.BUTTON1_MASK);
            robot3.delay(100);
        } 
        catch (AWTException err) {
            err.printStackTrace();
        }
    }
    public static void mouseGlide(int x1, int y1, int x2, int y2, int t, int n) { 
        // "t" being time and "n" being amount of steps, with more steps being smoother
        // mouseGlide code borrowed from http://stackoverflow.com/questions/9387483/how-to-move-a-mouse-smoothly-throughout-the-screen-by-using-java
        try {
            Robot robot = new Robot();
            double dx = (x2 - x1) / ((double) n);
            double dy = (y2 - y1) / ((double) n);
            double dt = t / ((double) n);
            for (int step = 1; step <= n; step++) {
                Thread.sleep((int) dt);
                robot.mouseMove((int) (x1 + dx * step), (int) (y1 + dy * step));
            }
        } 
        catch (AWTException e) {
            e.printStackTrace();
        } 
        catch (InterruptedException e) {
            e.printStackTrace();
        }
    }
}

我的问题是mousePress实际上不会正确发布。它要么根本不释放，要么在应该按下的时候释放。我克服了这一点，每次需要发布mouseMove时都使用它，但这不应该是必要的。我听说在每个mouseRelease后面设置延迟应该可以解决这个问题，但它什么也没做。我不明白为什么它不能正常工作，为什么我必须使用mouseMove而不是mouseRelease。我还尝试在每个字母上使用新的机器人，但没有任何区别。

如果代码运行时在绘制的每个字母之间没有mouseMove，它将无法正常工作。

此外，我在mouseGlide中使用了其他人的代码，因为这只是我在测试Robot类，因为我从未使用过它。

尝试使用InputEvent.BUTTON1_DOWN_MASK;。我使用mousePress和mouseRelease的方式和你一样，只有一个区别。
