How can i make a button trigger the Fullscreen Template?

hi mathias drejer

 you can use behavior script with very simple way
ok let say i have  2 picture and 2 buttons 

if i click button  1 picture 1 displayed and pic 2 disabled
to do that lets add a screen image ( button 1 )

click on the image and in Inspector panel add touch Input
make sure to select the button image in mesh visual

then add behavior script 

edit the behavior script to enable the image  1 when touch input (Tap)
like in image below

so far we have a button when we click on it it enable project 1
in same button add new behavior script 
but this time when it clicked disable project 2
so  the button wile enable project 1 and disable project 2

do the same steps with the second button but this time
enable project 2
disable project 1

if you need any help please let us know

Cheers.
