CAAnimations can be applied to multiple SCNNodes concurrently
You can create a CAAnimation and hand it to -[SCNNode addAnimation:forKey:] on as many nodes as you want. No apparent side-effects. I just couldn’t find this documented anywhere.
Animations only work when the node is already in the scene
If you try to add an animation to an SCNNode that’s not yet part of a scene graph, nothing will happen. It won’t give any indication of failing, and the performance of rendering implies it’s still running them, but there will be no visible effect. So, addChildNode: and then addAnimation:forKey:.
Radar or GTFO
Just ran across this old post by Daniel Pasco, which showed again up in NetNewsWire presumably because of some RSS reboot on their end. Anyway, it reminded me of dealing with 3rd party developers – mostly indirectly, through Developer Relations – and the trials it involved. I particularly like the captioned picture of Mike. Nice.… Read more
Different icons for release vs debug builds
Ben_hawk asked how to do this on Stackoverflow, and I was both curious how to do it myself. Turns out it’s not too tricky – see my answer in the same post. A big reason for doing this even early in development, prior to distributing builds to anyone else, is that it makes it much… Read more
keyDown: fires even when your app is in the background
It appears that the standard behaviour for an NSView (NSResponder in general?) is for it to “hold onto” pressed keys. That is, if a key is held down the view will keep getting keyDown: events until the key is lifted, no matter what else happens. So it can lose focus or the app loses frontmost… Read more
SCNView may change your point of view
Ugh… SceneKit is both promising and frustrating. It appears to be a very stereotypical case of “version 1” syndrome – nice idea, flaky implementation and very skimpy documentation. So amongst the many strange, undocumented foibles it has, one in particular is quite egregious. When you add an SCNNode to your SCNView-rendered scene, containing an SCNCamera, the… Read more
New iMac’s SD card slot
I find it odd that I haven’t seen or heard a single comment about the latest model iMac’s SD card slot being on the back, buried amongst the inaccessible ports. People complained quite vocally about it being merely on the side.
