Detailed Description

Client/server logic.

Date: 2003-12-02

This containes item logic for client/server. It doesn't contain the actual commands that send the data, but does contain the logic for what items should be sent.

Definition in file item.cpp.

Macro Definition Documentation

◆ MAXITEMLEN

#define MAXITEMLEN 300

This is the maximum number of bytes we expect any one item to take up.

Definition at line 36 of file item.cpp.

Function Documentation

◆ add_object_to_socklist()

static void add_object_to_socklist	(	socket_struct *	ns,
		SockList *	sl,
		object *	head
	)

static

Used in the send_look to put object head into SockList sl for socket ns.

Need socket to know if we need to send animation of face to the client.

Client wants to apply some object.

Lets do so.

◆ esrv_del_item()

void esrv_del_item	(	player *	pl,
		object *	ob
	)

Tells the client to delete an item.

Uses the item command with a -1 location.

◆ esrv_draw_look()

void esrv_draw_look ( object * pl )

Send the look window.

Don't need to do animations here This sends all the faces to the client, not just updates. This is because object ordering would otherwise be inconsistent
