I am calculating mouse velocity, but every now and then you get a 0 for
velocity eventhough its not 0 (setInterval prob I suspect). Any better
approach?
var MouseX;
var MouseY;
function determineVelocity():Void
{
MouseX = _root._xmouse
MouseY = _root._ymouse
setTimeout( calc, 9 );
};
setInterval( determineVelocity, 20 );
function calc():Void
{
var newMouseX:Number = _root._xmouse;
var newMouseY:Number = _root._ymouse;
var deltaX = Math.abs(MouseX - newMouseX)
deltaY = Math.abs(MouseY - newMouseY)
dist = Math.sqrt((deltaX * deltaX) + (deltaY * deltaY))
velocity = dist*31; // 31 = fps
trace( velocity );
};
