arc

The arc() method creates an arc/curve (used to create circles or partial circles).

Note: to create a circle with arc(), set the start angle to 0 and the end angle to 2 * Math.PI.

Parameter	Description
x	The x coordinate of the center of the circle.
y	The y coordinate of the center of the circle.
r	Radius of the circle.
sAngle	Starting angle in radians. (The arc's three o'clock position is 0 degrees).
eAngle	End angle in radians.
counterclockwise	Optional. Specifies whether draw the arc counterclockwise or clockwise. False = clockwise, true = counterclockwise.

Example

Var ctx = node.getComponent(cc.Graphics);
ctx.arc(100, 75, 50, 0, 1.5 * Math.PI);
ctx.stroke();
