P5 sound reference code#
Of code that makes the one rectangle, and change something in the new line. since there are two rectangles, you’ll need to duplicate the line.strokeWeight(…) sets the thickness of the stroke.Give the location of its center and not of the top left corner rectMode(CENTER) changes things so that when drawing rectangles, you.What you have to understand in order to do this challenge: In the p5.js reference, you can learn how to make other 2D “primitives” Us an x coordinate for 1/4 of the way across from the left edge. Us the coordinates of the center of the canvas. We can position shapes usingįractions of these dimensions. Side, and y is the distance from the top. Remember that x is the distance from the left In order to position them on the canvas, we How many of you completed it? Drawing Shapes Challenge 1, Lines from CornersĬhange the program so that instead of drawing one green line from the center to the mouse position, it draws two or more lines in different colors from corners. If you log in (with Google may be best), you can save your work with File -> Save. a function that creates a line, given two pairs of (x, y) coordinates-one.fill is the interior, and stroke is the outline.fills the entire canvas with the specified color.setup is called once at the beginning, and usually creates the canvas.often we use numbers from 0 to 255 to specify how much of each color we want.our eyes are sensitive to these three colors.the origin is at the top left, in 2D, and in the center in 3D.y coordinates indicate the distance in pixels from the top of the canvas.x coordinates indicate the distance in pixels from the left side of the canvas.What about the three numbers following stroke? Explanation of the Program Think about what width, height, mouseX and mouseY mean. Move the mouse over the rectangle and see what happens. Pay carefulĪttention to things like parentheses ( ), braces, commas, Mistakes that prevent the program from even starting. Unlike with block-based environments like Scratch, in JavaScript Line(width / 2, height / 2, mouseX, mouseY) It should draw a rectangle.Ĭhange that program to look like the following, and then run it. 3D Clock (change view in CodePen so code is on the left side).Conway’s Game of Life (a 3D rendering of the 2D game).Some of my favorite p5.js creations, to get ideas and inspiration: p5.js, for example is a framework created byįor other programmers to make graphics, sound and art. Programs for use by others, as packages, libraries, People who are good at specificĪreas of programming (graphics, physics, music, etc.) publish their (bouncing objects, collisions, gravity, etc.), it would take much If we all had toįigure out how to make 3D graphics or simulate physical processes Programmers build on the work of other programmers. Programs are written using programming languages. Programs run on computers of different sizes and types: Experiment, and make your own original creationsĬomputer programs are instructions for getting a computer to perform a task,.Read the p5.js reference and learn about more features.When you complete assigned work, there’s always more to do.
