Question

一张图片胜过千言万语。这是我的：

Messed up sprite next to good sprite

上图描绘了两个精灵，中间右边的那个是玩家，中间左边的那个是AI玩家。它们的两个初始化都使用相同的superClass。我们应该看到类似的质量精灵。

然而，正如你所看到的，正确的精灵在某种程度上是扭曲的。我还注意到来自同一个spriteSheet的其他精灵的斑点出现在一些动画帧的上方和下方。玩家精灵上没有进行任何转换。除了那些也在ai精灵上执行的动作之外，没有任何动作可以运行。

还有其他人遇到过这个吗？我甚至不确定如何说出这个问题;）还有其他问题吗？请问！

详细说明：我正在使用Cocos2d 1.0.0 ..在Lion上运行Xcode 4.1。

代码示例：此代码在包含CCFiniteTimeActions的NSObject初始化之后运行，并且一个CCSprite

变量“sprites”是指向CCSpriteBatchNode的指针。我确信他们指向同一个批处理节点，因为只有一个。

如您所见，此对象通过批处理节点将自己的动画添加到图层。

我将发布移动发生的方法：

moveAction = [CCMoveTo actionWithDuration:0.3 position:ccp(thisDoodad.newX, thisDoodad.newY)];
    if (thisDoodad.animation.visible == NO) {

        id beingVisible = [CCCallFunc actionWithTarget:thisDoodad
                                              selector:@selector(makeVisible)];
        id seq = [CCSequence actions: moveAction, beingVisible, nil];
        [thisDoodad.animation runAction:seq];
    } else {
        [thisDoodad.animation runAction:moveAction];
    }

自提问时起，我尝试添加以下行：

[[animation texture] setAliasTexParameters];

它消除了玩家的模糊精灵，但略微拉伸了图像。值得一提的是，每个精灵帧都是32x32像素，并没有填满整个帧另外，上面的代码行不会影响ai的sprite的外观。

* ------- * 编辑::

我修好了。

发生了什么：

我有两个浮点数，用于保存精灵即将移动到屏幕上的位置。我世界上所有其他精灵都来自玩家的参考。

在我的引用过程中，float被格式化为一个int，因此游戏中的每个其他sprite都会收到该位置的int版本。

这让我相信，在我的代码中某处必须有一些可以将这两个浮点数分开的东西。

感谢@jtbandes提供的“半像素值”提示。我仍然不知道这个位置如何成为一个整数但是整数:(

无论如何，将浮动更改为int会修复所有内容。

谢谢！

Answer 1

也许精灵的位置与半像素值对齐，例如150.5像素。这可能会导致视觉失真/模糊。

当没有应用比例时，导致精灵失真的原因
