Hello everybody,

timer stop gameover
Add the game over screen first, then stop greenfoot.
i have an actor gameover with the code:
public cc_GameOver()
{
setImage(new GreenfootImage("Game Over",48, Color.WHITE, Color.BLACK));
}
is that also ok?
And this is the code i have in my world class:
if (timer>0)
{
timer--;
if (timer==0) Greenfoot.stop();
}
addObject(timerText, 95, 25);
timerText.setcc_Text("Time left:" + (timer/60));
if (timer%60==0) timerText.setcc_Text("Time left:" + (timer/60));
Please use the code tag below the 'Post a reply' box for adding code into your posts. Also, you need to give enough information for us to know or be able to determine when the code is executed. The names of the methods the code reside usually helps; often, if called from the act method, its code may help. How and where the various fields are declared could help also.
I took the liberty of re-displaying you code properly:
if (timer>0)
{
timer--;
if (timer==0) Greenfoot.stop();
}
addObject(timerText, 95, 25);
timerText.setcc_Text("Time left:" + (timer/60));
if (timer%60==0) timerText.setcc_Text("Time left:" + (timer/60));Line 4 only shows one action being taken when the timer reaches zero -- that is, the scenario stops. That is where you will add your gameover actor into the world.
Line 9 appears out of place (like it does not belong with lines 7 and 8, but maybe somewhere else in your code.
oke thank you
i will try it right now
in the my world cc_Rotterdam i have:
and in my cc_GameOver i have:
public void act()
{
if (timer>0)
{
timer--;
if (timer==0) Greenfoot.stop();
}
addObject(timerText, 95, 25);
timerText.setcc_Text("Time left:" + (timer/60));
if (timer%60==0) timerText.setcc_Text("Time left:" + (timer/60));
}public class cc_GameOver extends Actor
{
/**
* Act - do whatever the cc_GameOver wants to do. This method is called whenever
* the 'Act' or 'Run' button gets pressed in the environment.
*/
public cc_GameOver()
{
setImage(new GreenfootImage("Game Over",48, Color.WHITE, Color.BLACK));
}
}Ok. With the blank line at line 8 of your act method, your initial post made it seem that you were showing two separate areas of code where in fact you were showing just one. The reason it appeared to be two separate areas of code is because they should be two distinct sets of code. Lines 9 and 10 perform things you only want done once. You want the timerText object to be added to the world once and its image initially set once. Things that you want done just once should not be in the act method (especially without any conditions placed on them being executed). Since these are things that you want done during the construction of your world, they belong in your world constructor. Another thing, line 11 should be executed only immediately after when the value of 'timer' changes; so, it should be in the 'if' block placed after line 5.
thank you danpost i've made the changes.
But how can i now get the game over screen when the timer is at 0???
this is what i have now in my public void act() in my world cc_Rotterdam
if (timer>0)
{
timer--;
if (timer%60==0) timerText.setcc_Text("Time left:" + (timer/60));
if (timer==0) Greenfoot.stop();
}i've come with this:
at 0 the words game over will come on my screen
if (timer>0)
{
timer--;
if (timer%60==0) timerText.setcc_Text("Time left:" + (timer/60));
if (timer==0)
{
addObject(new cc_GameOver(),getWidth()/2, getHeight()/2);
Greenfoot.stop();
}
}
Hello.@danpost, @JustMe I been searching in the internet on how to make a game over screen when the time is up and glad I found this but about your last comment, about line 4 and 7,I got syntax error in timerText.setcc_Text, and cc_GameOver() and getWidth().. Why? Can u tell me how can rid of the syntax error? Or something that I can declare? and oh, I put your code in the GameOver() subclass, is that right?
The timer code should be elsewhere -- probably in your world class. The only thing that you should have in the GameOver class is maybe something to give the actor its image (please review the entire discussion to see where everything led to).
