Processing mouse coordinates code#

Hey, i'm new to processing, i'm using it to make a flashless website, so i'm pretty much drawing on a canvas. Processing is a very cool way to draw stuff, specially for the webpages. Happy Coding is a community of folks just like you learning about coding.This is a copy paste of a post i made on the processing forum (where i haven't got an answer so far) thought i might as well try here. Bonus: make the game automatically end after 60 seconds! If the user types the wrong character, the game is over. If the user types it correctly, increase the score and show another character.

Create a typing game: show a random character on the screen.Let users click to add object, or press keys to change colors. Remember that scene you drew from a previous homework? Add user interaction.Instead of a circle, make it a spaceship (like from the game Asteroids) where you control the direction and acceleration. Create a program where the user controls a ball that bounces around the screen.For example, you could create a garden drawing program where clicking creates flowers (randomly sized and colored?), dragging creates grass, the mouse wheel adds butterflies, keyboard changes the background or sky… Create a drawing program for a specific scene.These are just suggestions, do whatever you want! Be creative! Maybe clicking creates a circle, dragging creates a rectangle, and the keyboard changes the color. It only makes sense to compare them to other preexisting variables (like SHIFT or LEFT). Notice that it doesn’t really make sense to display the value of some of these variables (like ke圜ode or mouseButton). Here’s an example that defines mousePressed, mouseReleased, and mouseDragged functions to change the background color: If you need to know which mouse button is pressed, check out the mouseButton variable.mouseWheel() is called when you scroll with the mouse wheel.mouseDragged() is called, you guessed it, whenever the mouse is moved while its button is pressed.mouseMoved() is called whenever the mouse moves.mouseClicked() is called when the mouse is clicked.mouseReleased() is called once when the user releases the mouse button.mousePressed() is called once when the user presses the mouse button.There are a bunch of mouse input functions that allow you to react to more specific events:

By writing code inside these functions, you can run code when these events happen. These one-time inputs are called events, and Processing provides a bunch of functions that it automatically calls whenever an event happens. But what if you want to detect one-time input like a mouse click? The mousePressed variable is useful when you want to do something continuously, as long as the user has the mouse pressed. See the Pen by Happy Coding ( on CodePen. Processing automatically updates these variables, so you can use them in the draw function to get the position of the mouse. Processing provides mouseX and mouseY variables that hold the current location of the mouse cursor in the window. Mouse Input The mouseX and mouseY Variables

This tutorial shows you how to get user input (things like mouse position, mouse clicks, and keyboard typing) to make your programs more interactive. So far your programs have mostly done stuff on their own, without responding to anything that the user does. You also know that Processing automatically calls the setup function once at the very beginning of the program, and then calls the draw function 60 times per second.

You also know how to modify variables over time to create animations, and you’ve seen that Processing gives you predefined variables like width and height. Now you know how to call functions, use variables, create functions, and use if statements.
