Hi All,
I am relatively new to PlayFab and I have ran across a few settings that I do not fully understand. I understand why you would not want the client to add virtual currency. However, I do not understand why you would not want the client to subtract virtual currency and post statistics. What is the difference between calling PlayFabClientAPI.SubtractUserVirtualCurrency in my client vs doing the same thing in cloud code?
Thank you,
Travis Pettry
I am only using this to deduct from the player lives that I am using as a currency.
In the released games, we don't recommend allowing clients to upload statistics, for example, this user has encountered the problem with players cheating :https://community.playfab.com/questions/27050/players-cheating-in-my-leaderboard.html
As for why you should using SubtractUserVirtualCurrency on CloudScript, because this API can make the balance become negative. And call it on CloudScript, you can check the balance with the authoritative code to prevent the Player from becoming negative due to the outdated balance data.
Besides, maybe you think that the abuse of this API will only hurt the cheater himself, but we also need to try to avoid the loss of ordinary players due to accidental errors in the client side.
