使用线程作为GameLoop [英] Using a thread as a GameLoop

问题描述

我需要做的是有一个循环，如果我想，我可以停止......我犯了一个新的线程，并把它命名为GameLoop我想这是尽我的位图的X和Y的变化，但是当我trye​​d运行我什么都没有移动时，它只是给我发送图片。我的继承人code，我做了什么错了？

 公共GamePage（上下文的背景下，ATTRS的AttributeSet）
    {
        超（背景下，ATTRS）;
            //其他code在这里
            螺纹gameThread =新主题（新GameLoop（））;
            gameThread.start（）;
    }公共类GameLoop实现Runnable
{
    公共无效的run（）
    {
        尝试{
            视频下载（速度）;
        }赶上（InterruptedException的E）{
            // TODO自动生成catch块
            e.printStackTrace（）;
        }        Log.d（LoopRunning，游戏循环正在运行！）;        开关（（INT）possition）
        {
        情况下0：
            如果（计数器＆LT; 110）{SUNY  - ;反++;}
            如果（计数器＆GT; = 110安培;＆安培;计数器＆LT; 240）{SUNY  - ; SUNX ++;反++;}
            如果（计数器＆GT; = 240安培;＆安培;计数器＆LT; 360）{SUNY  -  = 0.5; SUNX ++;反++;}
            如果（计数器＆GT; = 360安培;＆安培;计数器＆LT; 662）{SUNY  -  = 0.333; SUNX ++;反++;}
            如果（计数器＆GT; = 662＆安培;＆安培;计数器＆LT; 1004）{SUNY + = 0.333; SUNX ++;反++;}
            如果（计数器＆GT; = 1004安培;＆安培;计数器＆LT; 1104）{SUNY + = 0.5; SUNX ++;反++;}
            如果（计数器＆GT; = 1104＆放大器;＆安培;计数器＆LT; 1224）{SUNY ++; SUNX ++;反++;}
            如果（计数器＆GT; = 1224＆放大器;＆安培;计数器＆LT; 1345）{SUNY ++;反++;}
            打破;        情况1：
            如果（ZombieX＆下; canvasWidth / 2 + 300）ZombieX + = 10;            如果（计数器2＆LT; 110）{发呆 - ;计数器2 ++;}
            如果（C2的＆GT; = 110安培;＆安培; C2的＆LT; 240）{发呆 - ; MoonX ++;计数器2 ++;}
            如果（C2的＆GT; = 240安培;＆安培; C2的＆LT; 360）{发呆 -  = 0.5; MoonX ++;计数器2 ++;}
            如果（C2的＆GT; = 360安培;＆安培; C2的＆LT; 662）{发呆 -  = 0.333; MoonX ++;计数器2 ++;}
            如果（C2的＆GT; = 662＆安培;＆安培; C2的＆LT; 1004）{发呆+ = 0.333; MoonX ++;计数器2 ++;}
            如果（C2的＆GT; = 1004安培;＆安培; C2的＆LT; 1104）{发呆+ = 0.5; MoonX ++;计数器2 ++;}
            如果（C2的＆GT; = 1104＆放大器;＆安培; C2的＆LT; 1224）{发呆++; MoonX ++;计数器2 ++;}
            如果（C2的＆GT; = 1224＆放大器;＆安培; C2的＆LT; 1345）{发呆++;计数器2 ++;}
            打破;
        }
    }
}
 

解决方案

使用两个嵌套while循环像这样：

  @覆盖公共无效的run（）{
    而（gameShouldRun）{
        而（iterateGame）{
            //做游戏的东西
        }
    }
}
 

此外，运行默认情况下不循环。如果你想在游戏循环，直到停止，则需要在run方法while循环。

What I need to do is have a loop that I can stop if I want... I made a new thread and named it GameLoop I want this to do all of my bitmap X and Y changes but when I tryed to run what I have nothing moves, It just sends me a picture. Heres my code, what did I do wrong?

 public GamePage(Context context, AttributeSet attrs) 
    {
        super(context, attrs);
            //other code here
            Thread gameThread = new Thread(new GameLoop());
            gameThread.start();  
    }

public class GameLoop implements Runnable
{
    public void run()
    {
        try {
            Thread.sleep(speed);
        } catch (InterruptedException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }

        Log.d("LoopRunning", "The Game Loop Is Running!");

        switch ((int)possition)
        {
        case 0:
            if (counter < 110) {SunY --; counter++;}
            if (counter >= 110 && counter < 240) {SunY --; SunX ++; counter++;} 
            if (counter >= 240 && counter < 360) {SunY -= 0.5; SunX ++; counter++;}
            if (counter >= 360 && counter < 662) {SunY -= 0.333; SunX ++; counter++;}
            if (counter >= 662 && counter < 1004) {SunY += 0.333; SunX++; counter++;}
            if (counter >= 1004 && counter < 1104) {SunY += 0.5; SunX++; counter++;}
            if (counter >= 1104 && counter < 1224) {SunY ++; SunX++; counter++;}
            if (counter >= 1224 && counter < 1345) {SunY ++; counter++;}
            break;

        case 1:
            if (ZombieX < canvasWidth/2 + 300) ZombieX += 10;

            if (counter2 < 110) {MoonY --; counter2++;}
            if (counter2 >= 110 && counter2 < 240) {MoonY --; MoonX ++; counter2++;} 
            if (counter2 >= 240 && counter2 < 360) {MoonY -= 0.5; MoonX ++; counter2++;}
            if (counter2 >= 360 && counter2 < 662) {MoonY -= 0.333; MoonX ++; counter2++;}
            if (counter2 >= 662 && counter2 < 1004) {MoonY += 0.333; MoonX++; counter2++;}
            if (counter2 >= 1004 && counter2 < 1104) {MoonY += 0.5; MoonX++; counter2++;}
            if (counter2 >= 1104 && counter2 < 1224) {MoonY ++; MoonX++; counter2++;}
            if (counter2 >= 1224 && counter2 < 1345) {MoonY ++; counter2++;}
            break;
        }
    }
}

解决方案

Use two nested while loops as so:

@Override public void run() {
    while (gameShouldRun) {
        while (iterateGame) {
            // do game stuff
        }
    }
}

Also, run is not looped by default. If you want the game to loop until stopped, you will need a while loop in the run method.
