Hello–
I’m going crazy trying to figure out how to get my countdown timer working. I’ve attached my source if anyone is willing to take a look at it to see if they can figure out what’s being messed up. Here’s the scoop on what my app should do. It’s almost in working condition:
-
The user enters a task and a duration for that task (say 30 minutes), and both the task and the duration are stored in separate lists.
-
Once the user is finished entering tasks with accompanied durations, they press the start button.
-
At that point, I want the timer to look at the first stored task and accompanied duration, and begin counting down.
-
Once it hits 0, I want the timer to move on to the next task and alert the user. Right now, all the program does is go straight to the last task in the list.
-
I would like it to continue looping through the tasks until the user decides to press stop.
-
I don’t know how to get the timer to move from task A to task B, to task C, etc. Any help?
-
The main issue I’m having is found in my StartButton function. If you look at my source, you’ll see a commented-out while loop section that I was playing with to get it working.
-
I’m assuming it has something to do with the way my StartButton and Update functions talk to each other, but I’m unsure what to do.
If you’d rather not download my source code and look through it, here are some basic guts of my program…but it may make more sense to see the whole picture.
Thank you in advance, anyone who can help!
