The movedX variable in p5.js contains the horizontal movement of the mouse since the last frame of the sketch. A positive value indicates that the mouse moved to the right and a negative value indicates that it moved to the left in the last frame.
Syntax:
movedX
The program below illustrates the movedX variable in p5.js:
Example 1:
javascript
function setup() { createCanvas(400, 300); textSize(16); fpsSlider = createSlider(1, 60, 30, 1); fpsSlider.position(20, 40); } function draw() { clear(); text( "Move the slider to change the framerate " + "of the sketch" , 20, 20); // Set the framerate according to the slider frameRate(fpsSlider.value()); text( "Current Framerate: " + fpsSlider.value() + " FPS" , 20, 80); // Use the movedX property text( "The mouse moved " + movedX + " units in the x-direction" , 20, 140); text( "since the last frame" , 20, 160); } |
Output:
Example 2:
javascript
let gameOver = false ; function setup() { createCanvas(600, 300); textSize(16); } function draw() { clear(); text( "Move the mouse horizontally from one end to " + "the other end slowly to keep playing" , 20, 20 ); if (!gameOver) { // Use the movedX property to display the // amount of mouse moved text( "The mouse moved " + movedX + " units in " + "the x-direction" , 20, 60); // Get the absolute amount of mouse moved // and finish the game is it goes too fast if (abs(movedX) > 3) gameOver = true ; } else text( "You moved too fast! Refresh to try again" , 20, 80); } |
