Hi,
I want to create an app for kids to practice writing letters of the alphabet.
If a letter is diplayed on screen as dots and the user connect all the dots.
How would one implement this?
Thank you
You could establish a pattern for each letter like i.e. the capital letter L could have the pattern in a table:
1,0,0,
1,0,0,
1,1,1
you see that the 1´s make the shape of a L?
Now you can make another table that is empty and let the kids finger fill in the empty table (if you imagine a tic-tac-toe board) (this would of course involve a RuntimeEventListener that listens for the kid´s “move”. When the kid lifts his/her finger the listener can comare the two tables and see if they match up.
This could be combined with drawing a line that snaps to the center of each of the blocks in the grid and use some transition.to and other fancy cool corona stuff to make it slick and smooth 
Look at this illustration where I illustrate my thoughts:
first a grid with the use of a for loop (my example is just a 3 by 3 grid)
inside this loop you can put a black circle inside each grid cell or whatever, that represent 1 or 0
and the listener can check if the 1´s and 0´s x and y coordinates is within the range of the event.x and event.y (this will be the coordinates the kid just filled in in by dragging over the grid), then it can throw a positive response.
Keep in mind that this is just a thought I came up with now
Hope it will help you some of the way
ps1 I just made a tic-tac-toe my self
