'EventHandler.SendNetworkEvent("giveitem:BFG9000");'

[Matt]

From the EventHandler description in the wiki:

Note that any event handler can handle any name, so if you need to send a string you can simply check for Name starting with a value, for example:

Code: Select all

EventHandler.SendNetworkEvent("giveitem:BFG9000");

In the event handler, you check that the event's Name starts with "giveitem:", extract the following value and take action.

The example code is tantalizingly suggestive of the possibilities but I can't make heads or tails of how to use it based on the underlined description.

Is "giveitem" a special word here, or the name of a sample custom function? Is "BFG9000" converted into an int from the string, or is it treated as a class name, or something else? Or is it that you give a BFG and this returns the number of BFGs given???

It just passes the item to give as part of the name parameter. The wiki likely doesn't have an example for this because there was no built-in string splitting function until I suggested it somewhat recently.
Here's some actual EventHandler code for that:

Code: Select all

version "3.2.5"

class ItemGiveEventHandler : EventHandler {
    override void NetworkProcess (ConsoleEvent e) {
        if (e.Player < 0 || !(players [e.Player]) || !(players [e.Player].mo))
            return;

        let player = players [e.Player].mo;

        Array<string> command;
        e.Name.Split (command, ":");

        if (command.Size () != 2 || !(command [0] ~== "giveitem"))
            return;


        player.GiveInventory (command [1], 1);
    }
}

This should work. With this, you can do "netevent giveitem:BFG9000" in the console to give yourself a BFG.

Thanks, that's exactly what I was hoping for!

May I add your code to the wiki?

Sure. Should probably remove the version statement and change it to Allman style, though.
