Ok, sorry for spamming you with lots of questions, this should be my last post for tonight.
I'm porting a board game I love to the iPad. The key game mechanic I'm working on right now involves moving a line of stones in a row across a grid. For example, if I have 3 stones in a row like so:
. O O O . . .
I'd like to put one finger on each end of that group, then slide the whole group left or right.
To begin, I wanted to just get one stone moving, then start moving 2 or more once I have the basic workflow done.
After looking over the docs, it seemed to me that this would be the correct way to solve the problem:
* all stones needed to play the game are added directly to the stage when the game starts.
* at the top of a lua file, define group = Sprite.new()
* in a function that captures Event.TOUCHES_BEGIN events, locate the stone that was hit and add it to group.
* when I want to slide the group across the board, i can just update the X/Y position of the group, and all the stones in it (all one of them for now) will come along for the ride
* Once I am done moving the group, put the stones, one at a time, back into the stage, at the new position.
So far I have the first 4 points working for a single stone. Once I have all 5 points done, I'll add more stones to the group to ensure it continues to work.
The problem is at the fifth step. When I add the stone back to the stage, it goes right back to the location it was in originally. I tried to save the X/Y coordinates of the group beforehand, but that did not seem to work either.
I hope I'm explaining this clearly. Can you tell me how to move the stone from one group to another without moving it on the screen?
