I then show you this picture, but only for a fraction of a second, because I'm going to follow those instructions again and produce a new image for you to see a fraction of a second later (and I do that since I only have one purpose in life and it's not passing butter). The movedX variable in p5.js contains the horizontal movement of the mouse since the last frame of the sketch. Since each plant is a small array of numbers, you can smoothly change the values in this array, moving from one plant to another. I have already shown here the plants generated by the algorithm. Identity and graphic design by Jerel Johnson. p5.js is developed by a community of collaborators, with support from the Processing Foundation and NYU ITP. run reset copy X p5.js is currently led by Qianqian Ye and was created by Lauren Lee McCarthy. ![]() The system variable mouseY always contains the current vertical position. The 'mouseX' variable is used to control both the size and color of the rectangles. I follow a set list of instructions, and because those instructions tell me what to paint, when I am done following them, I have produced a picture. It is possible to cross them to get new ones. The system variable mouseX always contains the current horizontal position of the mouse, relative to (0, 0) of the canvas. To prevent the default behavior for this event, add return false to the end of the method. The browsers may contain different default behaviors attached to various mouse events. Because I am a robot, I can paint very fast. The mouseClicked () function in p5.js works when mouse button pressed and released. ![]() You real question is this: How can I make something that I've already drawn disappear?Īnd the answer is this: You need to understand how draw() works. You do need to "delete", what you are working with is not an "element", nor does this have anything to do with a "canvas" or the "canvas graphics". Code in this function block runs every 'frame'. Can be helpful for planning and answering the simple question: // 'What is the coordinate right HERE' // Code in this function block runs just once, at the beginning of the sketch. You're asking a simple question using a lot of specific keywords that is getting everyone else confused. // A basic p5.js sketch that displays the current mouse coordinates.
