Several things that you need to know before start
- v = a*t , l = v*t, l = a^2 * t (v = velocity, l = length, a = acceleration)
- Pythagorean theorem (please refer to: http://en.wikipedia.org/wiki/Pythagorean_theorem)
- Drawing line:
shapeobject.graphics.clear(); shapeobject.graphics.beginStroke("rgba(0,0,0,0.5)"); (0 ~ 1.0 in float) shapeobject.graphics.setStrokeStyle(5, "round"); shapeobject.graphics.moveTo( timeCircle.x, timeCircle.y ); shapeobject.graphics.lineTo( stage.mouseX, stage.mouseY );Please refer to : http://www.createjs.com/Docs/EaselJS/classes/Graphics.html
