Creating & Running

A lua file is called a script, to create and edit these scripts you need a Lua Editor such as notepad.

You can use any text editor, but to make your life easier, we recommend that you use Quick Edit.

Creating the script

---

For our first script, we're not going to do anything too complex. Just send some message into game console.

Type the following code into your chosen editor :

print( "Hello World!")
               

Saving the script

---

You're now ready to create the actual Lua script file. To find your lua folder follow the following path - it will look something like this:

srceng/hl2/custom/hl2gmed/lua/*
               

And you must save it with lua format (.lua)

Running the script

Running file script

To run any of your scripts you need to be playing a map.
Now, open the console and type the following :

lua_dofile scriptname.lua
               

Make sure, using lua_dofile command will run script from SERVER side.

That also means using lua_dofile_cl command will run script from CLIENT side.

Send it. If you did everything correctly up to this point you should see a message in the console :

Hello World!
               

The script has done exactly what you told it to.

Running script line

---

By using lua_dostring command, line from argument, will be executed from Lua SERVER side.

So logically using lua_dostring_cl command, same will be done from CLIENT side.

Look at the example:

lua_dostring print("Hello World")
               

After sending that command let's look at the output:

Hello World
               

Autorun

---

You can also use 'lua/autorun/' directory, for make script run every map start.

Autorun Structure

• 'lua/autorun/ - Shared
• 'lua/autorun/client/ - Client
• 'lua/autorun/server/ - Server

Simply just put lua script into one of those folders listed above, and it gonna be exectued at the map start.
