new to java programming how do i add a time limit to my card memory game..
I posted a sample scenario called Millisecond Timer with the source code provided. It is for anybody to make use of. You would have to copy/paste or create similar code and adjust it for your needs. For a time limit, you would want to check currentTime - startTime continuously until a certain period of time has elapsed.
Just add code in curly brackets for what to do when time has expired (and replace 'timeLimit' with a valid value in milliseconds).
1 | if (System.currentTimeMillis() - startTime > timeLimit) { } |
Alternatively, you just do the following
One thing to bear in mind is that timer is increased by one every act() method, so its not in "real" time, like seconds/minutes
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 | //Declare this field:private int timer = 0;//Include this in your act() method:public void act(){ //Your code timer++;}//And then have this somewhere:if(timer > 1000) //Replace 1000 with your limit{ //Do whatever}//To reset the timer, just do:timer = 0; |
You can either use the java.util.Date class or as suggested above use the System.currentTimeMillis() approach. Both are effectively same.
