Today I've updated my Tululoo example for analog controls.
If above image isn't very illustrative, these are small on-screen circles, that can be used in applications and games to convert user input from on-screen coordinate to a vector.
In contrast to not very documented example that I've made last spring, this is now presented as an extension.
That has detailed documentation, quite cleaner structure, and more functionality (for example, now it's possible to check if a specific analog control element was pressed, similar to keyboard keys).
As one can probably guess, it also handles touch input on mobile devices accordingly, allowing multiple controllers to be interacted with at once.
