Sample text
To make a rectangle at coordinate (180, 60) with a width of 220 pixels and height of 40, use the rect() function like this: function setup() { createCanvas(480, 120); } function draw() { background(204); rect(180, 60, 220, 40); } Example 3-6: Draw an Ellipse The x and y coordinates for a rectangle are the upper-left corner, but for an ellipse they are the center of the shape. In this example, notice that the y coordinate for the first ellipse is outside the canvas. js doesn’t have separate functions to make squares and circles.
Js includes a group of functions to draw basic shapes (see Figure 3-1). Simple shapes like lines can be combined to create more complex forms like a leaf or a face. To draw a single line, we need four parameters: two for the starting location and two for the end. Draw 19 Figure 3-1. js Example 3-3: Draw a Line To draw a line between coordinate (20, 50) and (420, 110), try: function setup() { createCanvas(480, 120); } function draw() { background(204); line(20, 50, 420, 110); } Example 3-4: Draw Basic Shapes Following this pattern, a triangle needs six parameters and a quadrilateral needs eight (one pair for each point): function setup() { createCanvas(480, 120); } function draw() { background(204); quad(158, 55, 199, 14, 392, 66, 351, 107); triangle(347, 54, 392, 9, 392, 66); triangle(158, 55, 290, 91, 290, 112); } Draw 21 Example 3-5: Draw a Rectangle Rectangles and ellipses are both defined with four parameters: the first and second are the x and y coordinates of the anchor point, the third for the width, and the fourth for the height.
Js Making Variables When you make your own variables, you determine the name and the value. The name is what you decide to call the variable. Choose a name that is informative about what the variable stores, but be consistent and not too verbose. For instance, the variable name “radius” will be clearer than “r” when you look at the code later. Variables must first be declared, which sets aside space in the computer’s memory to store the information. When declaring a variable, you use var, to indicate you are creating a new variable, followed by the name.
