[Tutorial][Work in progress] Hud elements

[pollo]

Hey

I had some trouble while setting the alpha value of some huds by using the "fadeovertime()" function (sometimes when 2 funcs change the alpha value of a same hud, it kinda "flashes", or become transparent/opaque in a short time), so I made this little one which seems to work fine.

		//call the function like this:

//thread _alphahud(level.hud,true);

//hud = your hud
//show = boolean (true, hud fades to opaque; false, it fades to transparent)
//you can also add a time variable in the function to edit it at your own

_alphahud(hud,show)
{
self endon("disconnect");
    for(i=0;i<20;i++)
    {
        if(show == true)
        {
        hud.alpha += 0.05;
            if(hud.alpha == 1)
                break;
        }
        else
        {
        hud.alpha -= 0.05;
            if(hud.alpha == 0)
                break;
        }
    wait .05;
    }
return;
}
