Question

嘿所以我正在研究slick2D中的一个小项目，我试图在播放器和npc之间添加交互，你可以点击选择回复。

public class House extends BasicGameState {
Image house;
Image message;
int msgID = 0;
...

public House(int state) {

}

public void init(GameContainer gc, StateBasedGame sbg)
        throws SlickException {
    ...

}

public void render(GameContainer gc, StateBasedGame sbg, Graphics g)
        throws SlickException {

    house.draw(playerPositionX, playerPositionY);
    player.draw(shiftX, shiftY);

    if (exitHouse == true){
        g.drawString("Would you like to exit the house? Y/N", 520, 270);
    }
    if (msgID == 1){
        message.draw(0, 570);
        mollerFace.draw(39, 610);
        ttf.drawString(46,588, "Moller");
        ttf.drawString(180, 609, "'Ello fella, you interested in some russian dolls?");
        ttf.drawString(908, 613, "- Russian dolls?" );//option 1
        ttf.drawString(908, 633, "- No" );//option2
        if (Play.spokeToMarkus){
            ttf.drawString(908, 653, "- Biscuits?" );//option3 hidden
        }
    } else if (msgID == 2){

        mollerFace.draw(39, 610);
        ttf.drawString(46,588, "Moller");
        ttf.drawString(180, 609, "Russian dolls are a set of dolls where each doll is different size, designed to fit in each other.");
        ttf.drawString(180, 636, "I can't recall how it's related to the module but it somehow is! ");
        ttf.drawString(908, 613, "- Interesting" );//option 1

            ttf.drawString(180, 609, "Biscuits? I don't really have any biscuits but I know where to get them from.");
            ttf.drawString(180, 636, "But first I'm dying, get me something to drink and I'll help ya' out");
            ttf.drawString(908, 613, "- Fine" );//option 1
        }
}


public void update(GameContainer gc, StateBasedGame sbg, int delta)
        throws SlickException {
    Input input = gc.getInput();

    up(delta);

    if (msgID == 1){
        //option 1
        if ((Mouse.getX() > 907 && Mouse.getX()< 1023)

                if(Play.spokeToMarkus){
                    msgID = 3;
                    System.out.println("5");
                }
            }
        }
    }
     if (msgID == 3){
        //option 1
        if ((Mouse.getX() > 907 && Mouse.getX()< 1023) 
                && (Mouse.getY() > 88 && Mouse.getY() < 107)) {
            if (input.isMouseButtonDown(0)) {
                msgID = 0;
                System.out.println("6");
            }
        }
    }

在运行游戏时：当说到npc msgID变为1时，玩家有2个选项＆＃34;俄罗斯娃娃＆＃34;和＆＃34;不＆＃34;。点击＆＃34;俄罗斯娃娃＆＃34;应该将用户带到下一条消息（msgID = 2），用户可以在其中回复＆＃34;有趣的＆＃34;将它们带回msgID = 0。

我的问题是当点击＆＃34;俄语娃娃＆＃34;时，重新运行更新方法，从而选择＆＃34;有趣＆＃34;即刻。我尝试修复它但没有成功，当我选择＆＃34;俄罗斯娃娃＆＃34;时，系统输出（＆＃34; 1,4＆＃34;）只需点击一下。

单击第一个选项会选择第一个选项两次，从而将玩家返回到原始状态。似乎无法修复：/

所以这里发生的事情是它需要输入鼠标按钮时的输入，所以当鼠标按钮关闭时它将执行它所涉及的所有内容。你需要做的是让它不仅仅是一个鼠标，而是你需要使if语句像这样。只是你知道这是sudo代码。

boolean isMouseButtonDown = false;

if(inputForMouseButton == true && isMouseButtonDown == false && msgID == 2){
   //do what ever is in the if statement for going to the next chat
   isMouseButtonDown = true;
}

if(inputForMouseButton == false && isMouseButtonDown == true){
    isMouseButtonDown = false;
}

在代码中尝试这样的事情。
