LibGDX 项目重启后才崩溃

[英]LibGDX Project crashes only after restarting

问题描述

有时，大约每 20 次尝试，游戏就会崩溃。

这对我来说没有意义。 第一次启动后，我尝试重现错误大约 500 次。 但没有成功。 重新开始游戏后，游戏在第 12 次尝试后崩溃。 这只影响 Windows。 即使在大约 2 部不同的 Android 手机上，我也无法重现该错误。 500 次尝试。

我一直在寻找类似的错误超过 8 小时，但它们并没有接近我的问题，也没有帮助我。

我到处都有 System.out.print 指令，并在 1 小时后发现游戏由于以下行而崩溃： body = world.createBody(bdef);

我尝试了所有建议的解决方案，增加了安全性 if 语句无处不在，并尝试了来自 Internet 的所有可能的建议（您可以在下面的代码中看到）没有任何帮助。

        texture = new Texture("spr_coin_strip4.png");
        textureRegion = TextureRegion.split(texture, 16, 16);

        setRegion(textureRegion[0][frame]);
        startcount = (int) (y * 100) / 16 * 10 - 64;

        bdef.position.set(getX() + getWidth() / 2, getY() + getHeight() / 2);
