My game could be described as being similar to flappy bird. My timer keeps count throughout the gameplay, and when the player dies the world changes to the gameOver screen. I want to add some code that states if the player has been alive for > than 30 seconds create the actor for the BronzeMedal in the gameOver world. This would also happen for the silver and gold medals, where the player lives for 1 minute and 1 minute 30 seconds respectively. Im not sure which of my classes is necessary so i will add what i think is :)
Code for my timer
The actor that removes the player and sets the world to GameOver

* the 'Act' or 'Run' button gets pressed in the environment.
*/
public void act()
{
long time = System.currentTimeMillis();
if(lastTime != 0) {
long diff = time - lastTime;
millisElapsed += diff;
}
lastTime = time;
updateImage();
}
public TimerActor() {
updateImage();
}
public void start() {
millisElapsed = 0;
lastTime = 0;
}
public void updateImage() {
// Calculate minutes & seconds elapsed
int millis = millisElapsed % 1000;
int secs = (millisElapsed / 1000) % 60;
int mins = millisElapsed / 60000;
// Convert these into text
String millisText = String.format("%03d", millis);
String secsText = String.format("%02d", secs);
String minsText = "" + mins;
String text = minsText + ":" + secsText + "." + millisText;
// Update the image
GreenfootImage img = new GreenfootImage(text, 25, null, null);
setImage(img);
}
