I'm making a game right now and want to add a timer to count down to my end game screen, I can get the text to show up on my game screen but the numbers won't go down.
Any feedback would help!

Biased note: Greenfoot is a great tool to learn to program in Java. Keep going! But learn to read documentation[1], please.
You are calling
subtractTime()only in the constructorTimer(). This way it will be called only once at creation time of yourTimerobject.Call it in the
act()method instead.It will be called every time when the Greenfoot system lets all actors and the current world, well, act. The time between the calls is controlled by the "Speed" control below the world's frame, or by the specific methods of the class
Greenfoot.If you need "real-time" values like seconds, do some research how to obtain seconds or milliseconds.
[1]: You can read Greenfoot's documentation in the Editor window by double-clicking on "World" or "Actor" in the class diagram on the right.
