how can i call the object from scence 1 to scence 2?
its like i have a selection of character (a) and (b)
if i choose character(a) he will be my character in scence 2?
how can i do this?
If I've understood you right, you need some place to store permanent data that persists when loading different scenes. So you could choose your character at Scene 1, then after loading Scene 2 you could know which character was selected at the previous scene.
If so, you need to place your vars at a master script and call the DontDestroyOnLoad function for the GameObject holding that script. You could then read and write those vars persistently from any scene.
Here you have a similar question answered:
