Game Over
In which part do you need help?
The game over or just the displayed time?
Well for the game over you just need a class GameOver that is shown when the game ends.
So when the game ends you execute this code:
For your counter:
Do you want a counter like a clock that counts up and shows the time while the game is running or do you just want to show the time when the game ends.
//when the game ends: getWorld().removeObjects(getWorld().getObjects(null)); getWorld().addObject(new GameOver(), getWorld().getWidth()/2, getWorld().getHeight()/2); //if you put this code in a world subclass you have to delete the getWorld(). parts;
the counter has to count how long the player survives and it should stop when he is dead
But do you want the counter to display the time while the game is running?
If yes there would be a little clock counting up the time in your game.
Ok then you need to declare a new class for the counter.
The class should look like this:
When you construct the level you need to add this code:
When the game ends you can get the current time using the method getTime() in the clock class.
import greenfoot.*;
import java.awt.Color;
public class Clock extends Actor {
private long startingTime;
private boolean counting = false;
public void act {
if (counting) {
displayTime(System.currentTimeMillis() - startingTime);
}
}
private void displayTime(long time) {
time /= 1000;
int minutes = time / 60;
int seconds = time % 60;
String time = minutes + ":" + seconds;
setImage(new GreenfootImage(time, 30, Color.black, new Color(0, 0, 0, 0)));
}
public void startClock() {
counting = true;
startingTime = System.currentTimeMillis();
}
public String getTime() {
time /= 1000;
int minutes = time / 60;
int seconds = time % 60;
String time = minutes + ":" + seconds;
return time;
}
}Clock clock = new Clock(); getWorld().addObject(clock, 50, 30); clock.startClock();
Hey, so sorry for reviving a year-old thread but when I tried to compile this errors keep popping up after I fix the previous ones. Also, I can't use the getTime() method. Not sure if anyone will reply, but it was a worth a shot.
@roeilthegreat, replace line 30 with these two lines;
I added the first line so that an outrageous String would not be returned if the timer was not running.
The second line was changed to simulate what the act method does with 'displayTime'
if (!counting) return "0:0"; int time = (System.currentTimeMillis()-startingTime)/1000;
