Common Mistakes

Using [RPC] instead of [PunRPC]

Forgetting the attribute entirely

Using a non-existent attribute like [RemoteCall]

In Unity with Photon, the attribute [PunRPC] marks a method as a remote procedure call.

💡 Hint

Common Mistakes

Using a method name like CallRemote or SendRPC which do not exist

💡 Hint

Common Mistakes

Including parentheses in the method name

Using camelCase instead of PascalCase

Using underscores in method names

Method names should not include parentheses in declaration and should follow PascalCase by convention.

CplayerScore

D"score"

💡 Hint

Common Mistakes

Using variable names that are not defined

Using quotes incorrectly around keys or values

The dictionary keys should be player names as strings and values should be the score variable.

5fill in blank

hard

Fill all three blanks to send a remote call only if the player score is greater than 50.

Unity

    photonView.[3]("UpdateScore", RpcTarget.All, playerScore);
}

Drag options to blanks, or click blank then click option'

💡 Hint

Common Mistakes

Using the wrong variable name in the condition

Using incorrect comparison operators

Using a wrong method name instead of RPC

The condition checks if playerScore is greater than 50, then calls photonView.RPC to update score remotely.
