mouseWentUp()
Category:Game Lab
Checks if the mouse button specified was released.
Some interactive games use the mouse for the user to control the game. mouseWentUp() generates a single true value when the mouse button is released, no matter how long the button is pressed. Use mouseDown() to continually check if the button is pressed.
Examples
function draw() {
console.log(mouseWentUp("leftButton"));
}
Move to the Mouse
Have the sprite move in the direction of the mouse when button was released.
// Have the sprite move in the direction of the mouse when button was released.
var sprite = createSprite(200, 200);
var angle;
drawSprites();
function draw() {
background("white");
if (mouseWentUp("leftButton")) {
console.log("here");
angle=(180/Math.PI)*Math.atan2(mouseY-sprite.y, mouseX-sprite.x);
sprite.setSpeedAndDirection(10, angle);
}
drawSprites();
}
