}var platypus = eventObj.target.parent.parent;platypus.gotoAndPlay("pop");function handleBalloonPopped(platypus) {platypus.falling = true;}And refer to them in the ticker function:platypus.platypusIdle.balloon.onClick = handleBalloonClick;platypus.onPopped = handleBalloonPopped;Now the platypus needs to fall to its death when the balloon pops. For that, we just need to add anaccelerating Y velocity to the basic platypus movement (which currently only involves X across thescreen):if (platypus.falling) { platypus.velY += 3; }Finally, let's get some points for that shot! Add this function:function updateScore(delta) {score = Math.max(0,score + delta);exportRoot.scoreTxt.text = "SCORE: "+score;}And refer to it in the ticker function (basic platypus movement):if (platypus.y > 450) {platypii.splice(i,1);exportRoot.removeChild(platypus);updateScore(100);}Yes, we get points, not when the balloon pops, but when the platypus crosses the bottom of the screen.That's so that we can get points and remove the platypus from memory, all at the same time. And wecan actually expand this same boundary-detection code to include the case where the platypus reachesthe left edge of the screen: (also remove from memory, but don't add points)if (platypus.x < -platypus.nominalBounds.width*platypus.scaleX || platypus.y > 450) {platypii.splice(i,1);exportRoot.removeChild(platypus);// add +100 points if it fell or 0 if it escapedupdateScore(platypus.y > 400 ? 100 : -500);}
