U3L16 - Collision score - limiting to +1

CS Discoveries Unit and Lesson Discussion

A few ways that I’ve seen students deal with this issue:

  • Move the sprite to a new location as soon as they touch
  • Use a boolean variable to track if a sprite has been touched
  • Use a coutdown/countup variable that gets reset when sprites touch eg:
var countdown = 0;
var score = 0;
draw() {
    // If the countdown hasn't finished, keep counting down
    if (countdown > 0) {
        countdown = countdown - 1;
    }

    if (sprite1.isTouching(sprite2)) {
        // Check if the countdown timer is active before scoring
        if (countdown == 0) {
            score = score + 1;

            // Start the countdown timer to prevent another score
            countdown = 10;
        }
    }
}
