Thanks for the response! Takes about 3 weeks to get a post and
response on here! Wow....
I am really just getting up to speed on formatting issue....crawling
right now.
I'm a noob, so this may seem obvious to veterans but...after digging a
little deeper into the demo, I found this;
/**
* Draws some apples.
*
*/
private void updateApples() {
for (Coordinate c : mAppleList) {
setTile(YELLOW_STAR, c.x, c.y);
}
And
map.putIntArray("mAppleList", coordArrayListToArray(mAppleList));
And cross referencing with the developers documentation;
"Normally, Lists allow duplicate elements, as compared to Sets, where
elements have to be unique. "
So, it looks like the answer to my question is that nothing is
preventing the second apple being drawn over the first. Unless I am
missing something here....
