How do I sync/save a value of variable throught multi layouts in multiplayer game ??

Hi guys i m working in a multipalyer game and i need some help on it please....

so i need to sync or save vaule of a globel variable and use it in differnt layouts in multiplayer game

for exemple : when the vaule of the variable named "S" changed from the layout 1 (player 1-peer-)

the vaule will change too in the second layout (player 2-peer-) in the same time

i tried many ways for this but nothing work to me .....

thanks ....any help will be greating for you

I can most likely help you, but I am not sure what you are asking. Do you want to sync the global variable from Layout 1 to Layout 2, on the same device, or from Layout 1 on one device, to Layout 1 on another device?
