This chapter will show the usage of Cocos Creator's graphic drawing component interface.
Method | Function Description | -------------- | ----------- | | moveTo (x, y) | Move the path to a specified point in the canvas without creating a line | lineTo (x, y) | Add a new point, and then create a line from the point to the last specified point in the canvas | bezierCurveTo (c1x, c1y, c2x, c2y, x, y) | Create cubic cubic Bezier curve | quadraticCurveTo (cx, cy, x, y) | Create a second Bezier curve

Third Party Library
The Graphics component's API is designed according to the Canvas drawing interface, and there are a lot of graphics libraries based on the Canvas drawing interface, such as paper.js, raphael.js. Using the standard canvas drawing interfaces and third party libraries, we can extend a lot of more advanced functions on the Graphics components.
Here are some third-party advanced drawing libraries and related demo based on Graphics component extensions.
