This is another post in the Lessons Learned series. Today’s lesson: immediate-mode GUIs
I’ve you have ever worked with Win32, GTK, or pretty much any GUI toolkit I know of, you’re probably used to treating the GUI as a bunch of controls. If you need a button on the screen then you create an instance of the Button class and add a pointer to that button to the Window object. Then behind the scenes Windows or GTK or whatever handles the rendering and processing of the button. All you have to do is wait for the user to click it.
This is another post in the Lessons Learned series. Today’s lesson: art
Chickens n Kittens has to run on a lot of different platforms on a wide range of screen sizes. Everything from an iPhone 4 with 640 lines of resolution to a retina display iPad with 1536 lines of resolution, and even higher for some PC displays. That’s quite a wide range! So in order to make sure the game looks just as good on a 640 display as a 1536 display, it contains multiple copies of each art asset in multiple sizes.
