I'm searching how to manage game framerate on mobiles devices, here is my problem:

On a computer with got something like that:

void main()
{
    while(game.isRunning())
    {
        event.handle(eventInfos);
        game.update(dt);
        graphic.render();
    }
}

On a mobile device with got something like that:

void update()
{
    game.update(dt);
}

void render()
{
    game.render(dt);
}

void event()
{
    game.handle(eventInfos);
}

When I search on internet, I found something like that everytime:

-> GameLoop

-> Fix your time step

I'm using IOS (With GLKViewController) and Android (with the NDK), and I've that rendering method is call from another thread

Thanks for your help!

  • \$\begingroup\$ The structure of the update/render functions is unrelated to desktop/mobile. For example, with love2d the render function is a callback too. The key difference is that for mobile you avoid drawing if nothing has changed, as battery life is at a premium. \$\endgroup\$ Oct 1, 2013 at 1:42

To get the right amount of movement when using a update(dt) function you must multiply the movement speed against delta time (dt = the amount of time since last frame update). So your position update could look like: newPosition = oldPosition + (moveSpeed * dt)

I hope this helps, I dont really understand what you mean by 'manage framerate'.
