hi.

this may be a easy simple question but i dont know about it.

im starting a new project and i want to take output for ios android and pc. as a developer how should i think about my project?

should i work parallel ? for example when i implemented move forward for my character by up arrow for pc after that i implemnt touching a up arrow looking sprite for android and ios or its better to focus on a certain platform and after taking last output for it start working for next platform? what is the best way? i think what professional teams do is they have diffrent team for each platforms and they work parallel but as a indie little team what is best way to do?

thank you for helping

is this a wrong question? really no answer for it?

Where I work, its common to focus on one version first (iOS) and port it later (Android) but on some occurrences, we've worked on both at the same time.

Your code should be built in such a way that one platforms ignores the state of the other altogether so that not all builds break for unknown reasons. I'm assuming you are differentiating the 'device' at boot and use this stashed reference to handle controls, display, etc?

I am not sure about mobile development practices, but in general for console games teams that want to develop on multiple platform simultaneously will have some kind of platform abstraction layer that handles the platform specific stuff (input, sound, graphics, file system, etc). Then the rest of the game code will interact with the abstraction layer, which will then do the correct thing for each platform. The vast majority of a game's code should be platform agnostic, and only lower level file, io, graphics, sound, etc code will have to be written for each platform.

This is pretty easy on consoles, because the major consoles are so similar to one another. On mobile things might be a lot different, given the massive variation in screen size and performance that there is in the mobile marketplace.
