PImage LEDON, LEDOFF; //load two img LEDON = loadImage("LEDON.png"); LEDOFF = loadImage("LEDOFF.png"); Mouse movement will light the LED which was realized in LEDButtonByOver. Mouse over: // When the mouse is moved, the state of the button is toggled.
void mouseMoved() {
if (mouseX > x && mouseX < x+w && mouseY > y && mouseY < y+h) {
button = true;
}
else {
button = false;
}
}
Mouse click will light the LED which was realized in LEDButtonByClick. Mouse Click: // When the mouse is pressed, the state of the button is toggled.
void mousePressed() {
if (mouseX > x && mouseX < x+w && mouseY > y && mouseY < y+h) {
button = !button;
}
}
Step 3：Compile the code and download it.
ResultMouse move on the LED, it will light, and trun off when leave it. Processing'S animation effects: Video |
