Hello!
I’ve been racking my head for a couple of days now, and I can’t seem to figure this out.
Basically, I am making a small card game which is multi player (basically Cards Against Humanity, but a online version). You start the game up, either host a game, or join a game and get into it. Your cards will spawn in front of you (C), when you click (A). These cards will have text on them, but only you can see this text, as the other player will see “Answer”.
When you press (B), it will draw a card to (D), but this text will show to both players, and it needs to be the same question. However, when Player 2 joins, he/she will draw theirs card like I have explained above, but they will show in (E). These cards will also have text on them, but will have “Answer” on them just like above.
Player 2’s view will be exactly the same as above, with Player 1’s cards being where (E) is. Each Player will also click a card and move it to (D), next to the (B) card. These will show their respective text to every player.
Reference Image: Imgur: The magic of the Internet
With the explanation out of the way, here is what I have so far:
Player 1: Imgur: The magic of the Internet
Player 1 hosts, joins the room and then clicks Answer, he gets his answer cards at the bottom. However, this lists 20 cards instead of 10, 2 on top of each other (which is why there is overlapping text). I have no idea why this happens. Anyway, he then clicks Question and the question card is pulled and works fine.
Player 2: Imgur: The magic of the Internet
Player 2 joins, and this shows. As you can see, the cards for Player 1 show as different text (which is not the text I want), but in the wrong position. They should be at the top, and not here. As you can also see, the Question card is there, but is also different text, which I also don’t want, it should be the same text as what is in Player 1. What is not seen in this screen shot is that when Player 2 clicks “Answer”, his cards show at the top, and not the bottom like I want them too.
Moving onto the code… it’s messy and isn’t done in the best way it could probably be done, but it’s my first game (I know, multi player with a first game!?)

This is attached to an empty GameObject called __GameMaster. It does the heavy lifting, such as the GUI, making the answers and questions and holding the amount of cards that the game will have.

This is attached to each card prefab, so that players can hover over them, spawn them and choose them.
There is also a Menu.cs, but all this does is do the multi player bit at the start – such as hosting a game, and joining then moving to the new scene (Level 1).
Sorry for the massive long winded explanation, and if anyone could help me get on the right foot that would be amazing. I have tried a few ways and it seems one step forward, a few back!
Thank you!
