unity3d中Transform组件变量详解

阅读更多关于 unity3d中Transform组件变量详解

Transform组件是每个游戏对象必须有的一个组建，因为你创建一个空物体，它也有该组建，因为unity3d是面向组建开发的一款游戏引擎。通过一张图片来看看它的属性你可以在通过代码查看这些属性的区别 Debug.Log("position " + transform.position); //世界坐标的位置 Debug.Log("localPosition " + transform.localPosition); //相对于父位置的坐标即把父物体当作自己的中心 Debug.Log("eulerAngles " + transform.eulerAngles);//世界坐标欧拉⾓度 Debug.Log("localEulerAngles " + transform.localEulerAngles);//相对于⽗级的变换的旋转欧拉⾓度 Debug.Log("localScale " + transform.localScale);//相对于父位置的缩放 Debug.Log("localRotation " + transform.localRotation);//相对于父位置的旋转 Debug.Log("rotation " + transform.rotation);//世界坐标的旋转上面提到了父位置？那是什么意思呢？现在创建两个cube 命名为cube1和cube2

Applying transform to UITextView - prevent content resizing

阅读更多关于 Applying transform to UITextView - prevent content resizing

问题 When I apply a rotation transform to a UITextView and then click inside to begin editing, it appears that the content size is automatically being made wider. The new width of the content view is the width of the rotated view's bounding box. For example, given a text box of width 500 and height 400, and rotated by 30 degrees, the new content width would be: (500 * cos(30)) + (400 * sin(30)) = 633 Or graphically: Interestingly, if you are already editing the text view and THEN apply the

问题 I'm trying to create a sort of perspective crowd for my website. It's literally a ul full of flat images, and I want to create a "curved" feel like a rounded crowd. Where it's inwards and perceptively smaller towards the inside and curves out towards the ends. The poster circle example is the closest I can find http://www.webkit.org/blog-files/3d-transforms/poster-circle.html except I don't need the "front" - just the back. Each image is 100px x 100px, 23 images per row and four rows. I'm

Dynamically Change a Rotation Animation in WPF

阅读更多关于 Dynamically Change a Rotation Animation in WPF

问题 I am using a DoubleAnimation to anamiate the Angle property of a RotationTransform. Several times per second, I need to change the rate of the rotation in response to external data so that the rotation speeds up and/or slows down (smoothly) over time. I am currently doing this by using a DoubleAnimation that repeats forever from 0.0 to 360.0 with duration X, then several times per second: Grab a new value from external data Modify the rate on the DoubleAnimation to that value Re-Apply the

问题 So I have an input file that uses my company's namespace in the default namespace ( xmlns="companyURL" ) but I want my output file to use something other than the default namespace ( xmlns:cmp="companyURL" ). So I construct my file using the cmp namespace, but then I want to copy some of the inner elements: <xsl:element name="cmp:container"> <xsl:for-each select="foo"> <xsl:copy-of select="." /> </xsl:for-each> </xsl:element> Unfortunately, what this does is define the default namespace for

问题 I am using AJAX live search to generate user-profile-specific links. It works well, I always end up at the profile I want to, but there ist an issue. Let's do this for user 1 (username = testuser; user_id = 1; blogname = testblog). If I search for "test", both links will be displayed, the link to testuser's profile, and the link to testuser's blog. The strange thing now is, the links work as if they would look like this: profile.php?user=1&page=profile profile.php?user=1&page=blog but the

问题 I've got an image (a straight line) and am trying to rotate it in some angle from a specific point. What happens is that the image is rotated from the center point of itself. I wan't a way through which the base of the image remains the same and it rotates in the angle I want to, just as in case of a clock. I use Compass2.layer.anchorPoint= CGPointMake(0.5,1); [Compass2 setTransform:CGAffineTransformMakeRotation(XXXX)]; However it shows Accessing unknown 'achorPoint' component of a property.
