Ok so I have a problem that I don’t quiet under stand… Which is the focus of dragging many objects… In my code I was able to click on an object which then changed to another object and I can drag that other object any where on the screen… When I release the mouse it seems to loose its focus and it just sits there on the screen… I can no longer drag that other object…
I studying some example code which does the same thing but when I add it seems to mess things up… I know I am missing this bit of code in the “began” phase[lua] – Store initial position
t.x0 = event.x - t.x
t.y0 = event.y - t.y[/lua]
and this in the “moved” phase[lua]t.x = event.x - t.x0
t.y = event.y - t.y0[/lua]
and this at the “end” phase[lua]display.getCurrentStage():setFocus( nil )
t.isFocus = false
[/lua]
When I add that it seems to bring the second object on the top left of the screen. and even when I add local t = event.target It doesn’t seem to like that either… Here is my code
[lua]–[[
