LibGDX精灵被绘制两次
因此，我回到了街头霸王libgdx克隆版，而Ive设法绘制了Ken的动画。但是，我意识到，一旦删除了背景，两个ken就会被一个接一个地绘制，您只能在跳跃时看到（删除背景后），另一个ken精灵不会跳跃。但可以水平移动。
我的问题是，我是在哪里定义Ken的，还是我两次设法吸引他？
我很困惑...

我显然不需要这种效果，因为我只需要1 ken。我不明白为什么它被两次绘制。
如果在我的背景上放了一个不跳的ken，它就位于背景后面，而您看不到它。...谢谢

我仍然有两个肯。
2 个答案:
答案 0 :(得分：2)
在Ken类中，您重写了draw（）方法以自己绘制Ken，但您还调用了super.draw（）来绘制Ken。
更改：
@Override
public void draw(Batch batch, float parentAlpha) {
super.draw(batch, parentAlpha);
Color color = getColor();
batch.setColor(color.r, color.g, color.b, color.a * parentAlpha);
batch.draw(reg,getX(),getY(),getWidth()/2,getHeight()/2,getWidth(),getHeight(),getScaleX(),getScaleY(),getRotation());
}
收件人：
@Override
public void draw(Batch batch, float parentAlpha) {
Color color = getColor();
batch.setColor(color.r, color.g, color.b, color.a * parentAlpha);
batch.draw(reg,getX(),getY(),getWidth()/2,getHeight()/2,getWidth(),getHeight(),getScaleX(),getScaleY(),getRotation());
}
因为super.draw（）已经绘制Ken，三行之后您使用batch.draw（）第二次绘制Ken
答案 1 :(得分：0)
您的Player类的样子如何？我目前仅看到一行实际在屏幕上绘制纹理区域的地方。
batch.draw(reg,getX(),getY(),getWidth()/2,getHeight()/2,getWidth(),getHeight(),getScaleX(),getScaleY(),getRotation());
我的猜测是，由于您希望将每个“玩家”绘制到屏幕上，因此您也正在此处绘制它。因为您还通过拥有super.draw(batch, parentAlpha);来调用播放器的draw方法，所以它将同时绘制两者。
