I need to elongate, extend, make longer or whatever when i “slice/drag”. Something like in flow game, when you need to rech one point to other, or WordSearch ( https://play.google.com/store/apps/details?id=com.melimots.WordSearch ) when you drag to get two letter. In the last case is not exactly my case, because isn’t a square that’s make longer.
Pff, it’s hard to explain.

It works if it’s horizontal, but if it get degrees, it doesn’t work.
This is the code:

It doen’t need images, u can compile it. Thanks.
PS: resume
I need a rectangle that make longer wherever i slice/drag it.
