Once the train has traveled the 200 pixels, it is reset back to 0. The background graphic has an extra 200 pixels worth of image that is used to simulate movement. In my animation I track how far the train has "traveled". Separate and link layers to derived variables Very complex scenes will render very large Swift/ObjC files. If it's a simple loop, you might not need a background. Getting your source layers right before you start animating will save you headache in the end. It is important to think through how you expect your animation to occur. PaintCode will maintain groups and layers from Sketch 3.įor this stage I had to go back to Sketch3 multiple times to adjust the distribution of track cells, clouds, and hills in background. You must ipmort the SVG layers from Sketch 3 into PaintCode. Since you're drawing vector art you can provide a multiplier to easily scale up the resolution for higher levels of detail. Sketch3 lets you easily export art in any popular format (PNG, JPG, SVG). The height should keep the same aspect ratio depending on width of screen. To accomodate smaller screens, I use constraints and pin the sides to the leading and trailing edgesof the view. I aimed for a final target scene 400 pixels wide by 100 ixels high to account for the wider screens on the iPhone 6/+. I want him to move up and down as the train wheels turn. I then cropped out wormy from one of the drawings I made prior.

Later, I explain how to animate them in a realistic fashion. The bar connecting three wheels is a group of shapes. Next, I drew Timothy the Train (the original files are much more detailed). This width will allow enough space for moving the background to the left as Timothy chugs along. I made some hills, clouds, dirt, and a train track. I opened up Sketch and drew a background.
(I'll be covering my experience going through tutorial later) I was about to tweet out asking for ideas when I realized I have wanted to build a custom ActivityIndicator when people pull-to-refresh content on my app. Quick note: these are stages vs steps and you will find yourself hopping around each stage as you fine tune your designs.
#PAINTCODE SWIFT MAC#
PaintCode is a Mac Desktop app that lets you control your designs programmatically. If you've learned Sketch or if you know how to illustrate using vectors (Adobe Illustrator), you should consider giving PaintCode a try.
