@fastlane69 I'm using A7, so ya I'm using lite-c.

@JCL, okay well in that case I must be doing something horrificly wrong. Here is my full test script:

Code:

---

#include <acknex.h> // Pure Mode
#include <default.c>

PANEL* pnlTesting =
{
	flags = VISIBLE;
	digits(300,300,"mydata.x: %015.5f",*,1,mydata.x);
}

typedef struct MYDATA
{  
	//int x;
	var x;  
	char c[20];
} MYDATA;
MYDATA mydata; 

//receiving data
function on_client_event(void* buffer) 
{  
	//	if(event_type == EVENT_DATA)    
	memcpy(mydata,buffer,sizeof(MYDATA));
}

function main()
{
	level_load("testing.wmb");
	wait(-1);
	screen_color.blue = 255;
	#ifdef server						//if we defined this game as a server
		while(connection & 0) {wait(1);}	// wait until we have a connection
	#endif

	#ifdef client						//if we defined this game as a client
		while(connection & 0) {wait(1);}	// wait until we have a connection
	#endif

	//	on_server = server_event;
	on_client = on_client_event;
	
	player = ent_create("testing.mdl",vector(200,0,0),NULL);
	
	wait(-1);
	while(1)
	{
		wait(1);
		if(key_q == 1 && connection == 3)
		{
			while(key_q == 1){wait(1);}
			beep();
			// sending data
			mydata.x = 1234;
			strcpy(mydata.c,"Test!");
			send_data_to(NULL,mydata,sizeof(MYDATA));
		}
		
		if(key_w && connection == 3)
		{
			while(key_w == 1){wait(1);}
			beep();
			mydata.x = 54321;
			send_var_to(NULL,mydata.x);
			
		}
	}
}

Here is a downloadable link of the script that's ready to go:

send_var works fine when I change mydata.x to var. No matter what, send_data wont work. It doesn't even effect the bandwith
