Hi Guys!
Thank you a lot for the tips!
I solved my night with the unity onclick direct on the unity button.
Just drag and drop the script to the button on the unity and I had acesses to the functions that I want...
some functions I had to make a public void to see in the button onclick options...
In the end the script maybe not work for me
I need take screenshoots from the camera and load this for the screen/HUD when the player want see, like a gallery image. Is for kids and because this I can't save on the system library, the kid can't go out of the app.
If you guys have an asset to do this I'll buy for sure!
Thanks again!
