绕锚点精灵 [英] rotate a sprite around an anchor point

问题描述

我有一个精灵：

ombreoeuf1 = [CCSprite spriteWithFile:@"mangeurcentremieu3_03.png" ];
ombreoeuf1.position = ccp(240,160);
[self addChild:ombreoeuf1];

和我想不断旋转它周围的锚点。我该怎么办呢？

And I would like to rotate it constantly around an anchor point. How can I do it?

推荐答案

您可以先通过设置属性设置锚点 anchorPoint ，例如：

You can first set anchor point by setting the property anchorPoint, for example:

[ombreoeuf1 setAnchorPoint:ccp(0,0)]

通过设置另一个属性，然后设置旋转（度）旋转：

[ombreoeuf1 setRotation:90]

anchorPoint 和旋转是的的CCNode类，这是CCSprite的父。

anchorPoint and rotation are both properties of CCNode class, which is the parent of CCSprite.

更新

根据您的意见，似乎你想要的是一个旋转的精灵，从来没有停止？这里是一个让精灵旋转每0.1秒10度的例子：

According to your comments, it seems that what you want is a rotating sprite which never stops? Here is an example which let the sprite rotate 10 degrees per 0.1 seconds:

[sprite runAction:[CCRepeatForever actionWithAction:[CCRotateBy actionWithDuration:0.1 angle:10]]];
