graphics arc how to update endAngle to make a ring timer

[espace]

hi, if i use the arc and i would update the endAngle how do you do ?

i try with a loop but it lag a lot. it seems that it redraw a new arc each time..

thanks.

 

function create() {

    var graphics = game.add.graphics(game.world.centerX, game.world.centerY);

    graphics.lineStyle(0);

    graphics.beginFill(0xFF3300);

//posx,posy,radius,startAngle,endAngle,clockwise
    graphics.arc(-100, -100, 135, game.math.degToRad(0), game.math.degToRad(90), true);

    graphics.endFill();

}

not sure if this is 100 percent what you're looking for but m1erickson has a really nice jsfiddle on it at http://jsfiddle.net/m1erickson/mYKp5/ that i have used before. it is quite clean imo.
