In the spirit of sharing more of the tech behind the scenes, and reasons why some things are the way they are, this post contains an overview of Unity's serialization system. In the scene, you need to use "Image" game object instead of "RawImage" game object to load the sprite. The Image Transmission component uses re-mote procedural calls (RPCs) provided by ulink6 to send the image byte arrays to the client. Invoking the RPC method is also simple – you grab hold of the PhotonView component and use the RPC() method on it and there’s a target parameter on there which was really interesting to me. 8 Additional downloads. There are two types of RPCs in the network system, Commands - which are called from the client and run on the server; and ClientRpc calls - which are called on the server and run on clients.

The difference with respect to simple call is that the client methods return an instance of a call object. Unlike c++ std containers, in Unity there is no API to reserve memory upfront for the Managed Heap. So switch byte 0 of your array with byte 1. YARN Resource Managers (RMs) and Node Managers (NMs) co-operate to execute the user’s application with the identity and hence access rights of that user. I came across the need to send structured data to and from a server on one of my projects, and figured it would be worth my while to use JSON.

C# already has methods for converting byte arrays to Base64 strings and vice versa. There are positive (uintXXX and intXXX >= 0) and negative (intXXX < 0) integers. I want simpler algorythms than lempel-ziv, to compress small count of bytes, say 500 bytes. When you setup a Remote Procedure Call you will notice that the argument supplied to this is called RpcArgs. High speed and reduced memory footprint are not the main goals of the project.
