Hey, all!
I've been having some trouble with my multiplayer game. I've been using this tutorial -
My code is posted below. Any help would be appreciated. Thanks!
I have an autoload script (GameManager) that holds one variable: Players - an empty dictionary.
In my Network script, attached to the main menu, I have a function (Send_Player_Information) that syncs player information across all peers. This syncs 3 parameters (1 empty string, 1 multiplayer unique id, and 1 boolean variable (is_vampire)). 2 parameters are synced perfectly, but I can't get the third to work right. It's probably staring me in the face but I just can't find what's wrong.
I have a button that switches a bool variable (is_vampire) between true and false.
I have added this variable to the 'Send_Player_Information' function (see below). Everything works perfectly on the host, but the client side just resets to the default variable value, even if I have changed the value in-game through a button press. I have tested everything before the 'Send_Player_Information' function and the variable's value is changed on command, but when the function is called, the value received is different than the value I thought I sent.
Please let me know if you need any more info! Thanks in advance!
