Typing Game: pop() the first word in a stack one at a time

By cycv5, with 1 reply.
Replied to by danpost, almost 8 years ago:

You cannot pop the elements from the stack unconditionally if you want the list to retain anything. The command to pop needs to be in an 'if' block or something similar.

Line 5 assigns a new List object to 'ene' every act. You need to move that line outside of the method for it to remain persistent as long as the World object exists.

Thank you very much, really helpful!!

I need help! How do you make it when a certain amount of points is not reached Game over

when the person doesn't get a certain score how do I make it game over.

Well, first you would need some indicator for when this condition should be checked. This could be a time limit or a limit on number of moves. It could be at a certain break point as like the end of a level or something else. Whatever this indicator is, when indicated, check the score and either allow the game to continue or not. To stop the game, usually all it takes is a "Game Over" text message (with possibly showing the score) and stopping the scenario (using "Greenfoot.stop();").

<Code Omitted>i found this, but i dont knew how to use it. Could you help me?

For a triangle 'nPoints' would be '3' and 'xPoints' and 'yPoints' would both be int arrays of length 3. Let us say you had an image of size 100x100. To draw a triangle that goes from bottom-left corner to bottom-right corner to top-left corner (back to bottom-left corner), then you have this:

Im looking to make a basic 10 second timer in my game. The code goes along the lines of whats given below, my issue is knowing how long a second is in this fashion, is it 60 for running at 60fps? Or is it something other? << Code Omitted >>

Actually, it varies depending on the speed of your system. However, in general, at normal running speed, it is around 60 fps. Therefore, initializing your 'time' field to '600' would be about right. Sidenote: it is a bit strange to see a 'while' where an 'if' is sufficient. You could also code act method as follows:
