PaperCircle

On this page you find the documentation for the paper figure PaperCircle.

Introduction

PaperCircle is a figure that you can use to draw a circle in a Paper component.

backgroundColor() - Setting the background color

Use the configuration method backgroundColor() to tell the PaperCircle figure which color it should have. Pass it the name of the color in English as a string, such as `red`, or `blue`.

If you don't call backgroundColor(), `black` will be used as the default color.

class StartPage extends Page{
	createGui(){
		return Box.aspectRatio(10, 10).child(
			Paper.coordinateSystem(10, 10).showCoordinates().backgroundColor(`orange`).children(
				PaperCircle.backgroundColor(`red`),
			)
		)
	}
}

radius() - Setting the radius

Use the configuration method radius() to tell the PaperCircle figure which radius it should have. Pass it the radius as a number.

If you don't call radius(), the radius will be 25% of the coordinate system's width/height (whichever that is smallest).

class StartPage extends Page{
	createGui(){
		return Box.aspectRatio(10, 10).child(
			Paper.coordinateSystem(10, 10).showCoordinates().backgroundColor(`orange`).children(
				PaperCircle.radius(1),
			)
		)
	}
}

center() - Setting the center position

Use the configuration method center() to tell the PaperCircle figure where the center of the circle should be. Pass it two numbers:

• The X coordinate of the center
• The Y coordinate of the center

If you don't call center(), the circle will be positioned in the center of the coordinate system.

class StartPage extends Page{
	createGui(){
		return Box.aspectRatio(10, 10).child(
			Paper.coordinateSystem(10, 10).showCoordinates().backgroundColor(`orange`).children(
				PaperCircle.center(3, 3),
			)
		)
	}
}
