If been back to working with multisync and i cant figure out how to send 3 strings to the server .

+ Code Snippet

NetPutString(buf);
				NetPutString(bufy);
				NetPutString(bufz);
				NetSendAll();
				NetSend(0);

When i do i get a result like this for example

+ Code Snippet

str str string//tempX
str string//tempY 
string//tempZ

where tempZ is the only one that holds the actual message

Server

+ Code Snippet


		while(NetGetMessage()){//sometimes i use if, works the same
			NetGetString(tempstrX,256);
			NetGetString(tempstrY,256);
			NetGetString(tempstrZ,256);
			
		}

Show us more code? Like what you're doing to those buffers you use to send strings.

Indeed, we need to know how those variables are declared and such.

You aren't allocating any space to store the strings, you've simply made char pointers which point to a string literal (which is not meant to be modified).

I've changed it to char tempstrX[256]; etc. and that eliminates the repeated strings but it still stores the same value in all of the strings

Well, you are just writing the X position each time.
