SDL代码仅在我的计算机上正常工作

Question

所以我正在学习c ++并决定尝试SDL，这样我就可以习惯使用类了。游戏基本上是一个太空射击游戏，所以我写了一些允许“射击子弹”的代码。代码在我的电脑上工作正常，子弹从X点到Y点没有问题。当我试图运行时在2台不同的计算机上游戏“子弹”非常多（它们会随机消失并且随机而来）。其余的游戏运行正常。我在两台计算机上测试了帧率，fps超过300

有谁知道是什么原因以及如何解决？

如果您出于某种原因需要它，可以使用以下代码（针对项目符号）：

//LOAD BULLET IF FREE

if(bulletEnemyCooldown.getTicks() > bulletEnemyCooldownVar)
{
    bulletEnemyCooldown.reset();

    for (int i = 0; i < kShips; i++)
    {
        if(!evilShip[i].getIfDead())
        {
            for(int j=0; j<99; j++)
            {
                if (evilShip[i].getIfBulletFree(j))
                {
                    evilShip[i].setKBullets(evilShip[i].getkBullets() + 1);
                    evilShip[i].setRectPos(evilShip[i].getPosX(),evilShip[i].getPosY(),j);
                    evilShip[i].setIfBulletFree(false,j);
                    break;
                }
            }
        }
    }
}

//CHANGE BULLET POS IF SLOT OCC AND RENDER

for (int i2 = 0; i2 <= kShips; i2++)
{
    if(!evilShip[i2].getIfDead())
    {
        for(int j2 = 0; j2<evilShip[i2].getkBullets(); j2++)
        {
            if (evilShip[i2].getIfBulletFree(j2) == false)
            {
                evilShip[i2].setBulletRectY( evilShip[i2].getBulletRectY(j2) + bulletS,j2);
                enemy_bullet_texture.render(gRenderer, evilShip[i2].getBulletRectX(j2), evilShip[i2].getBulletRectY(j2));
                evilShip[i2].setBulletDis(evilShip[i2].getBulletDis(j2) + bulletS,j2);
            }

        }
    }
}

//CHECK FOR ANY COLLISION AND FREE BULLET IF FOUND

for (int i = 0; i < kShips; i++)
{
    for (int j = 0; j < evilShip[i].getkBullets(); j++)
    {
        if(!evilShip[i].getIfDead())
        {
            if (checkCollision(evilShip[i].getBulletPosRect(j), mainShip.getmCollider()))
            {
                evilShip[i].setIfBulletFree(true,j);
                evilShip[i].setBulletDis(0,j);
                evilShip[i].setKBullets( evilShip[i].getkBullets() - 1);
                evilShip[i].setRectPos(0,0,j);

                boolMainShipContact = true;

                mainShip.curSetHP(mainShip.curGetHP() - evilShip[i].curGetATK());
                kShipContact = i;

                score -= rand()%(10 * currentLevel);
            }
        }

        // FREE BULLET IF FOUND OFF SCREEN

        if (evilShip[i].getBulletDis(j) > SCREEN_HEIGHT)
        {
            evilShip[i].setIfBulletFree(true,j);
            evilShip[i].setBulletDis(0,j);
            evilShip[i].setKBullets(evilShip[i].getkBullets() - 1);
        }

    }
}
