I'm making a game involving hit detection. Simply put, when a rectangle controlled by the player hits a circle, the score is supposed to increase by one. However what is happening right now is that instead of the score going from, let's say, 1 to 2 when there's a hit, it goes 1 to 2 to 3 to... 25, etc depending on how long the rectangle is overlapping with the circle.

How can I get it to increase by ONLY 1 each time there's a hit?

Here is my code:

// this function is in my player (rectangle) class
void collision(Object o) {

    if (abs(x - o.x) < w/2 + o.w/2 && abs(y - o.y) < h/2 + o.h/2) {
      hit = true;

    // sb.score is an integer from the scoreboard class, it represents the score
      sb.score += 1;

    }
    else {
      hit = false;
    }
  }

Thanks in advance :)
