| Name | mouseMoved() |
|---|---|
| Examples |
// Move the mouse across the image
// to change its value
int value = 0;
void draw() {
fill(value);
rect(25, 25, 50, 50);
}
void mouseMoved() {
value = value + 5;
if (value > 255) {
value = 0;
}
}
|
| Description |
The mouseMoved() function is called every time the mouse moves and a mouse button is not pressed. (If a button is being pressed, mouseDragged() is called instead.)
Mouse and keyboard events only work when a program has draw(). Without draw(), the code is only run once and then stops listening for events. |
| Syntax | mouseMoved() mouseMoved(event) |
| Returns | void |
