addCentralForce(Cube,{8,0,0},"local")

Also, it is best to name objects in the Editor also:

cube = getObject("Cube")

Then your code would be:

addCentralForce(cube,{8,0,0},"local")

And you would be adding a force to the "cube" variable, which is getting the object named "Cube" in the editor.

--get stuff
Cube = getObject("Entity0")

function onSceneUpdate()
    if isKeyPressed("W") then
        addCentralForce(Player, {8, 0, 0}, "local")
    end

end

My first shot at Lua ...lol
Also when I exit maratis and I try to open a project and then load a level a first it seems all right but when I try to publish it (File->Publish Project) it says that I need to open a project first, but I have.
(Nevermind, fixed the publish thingy, but still wondering about the script I guess im going to sleep on it.)
Solved the code (feel so dumb) I left  typed Player instead of Entity in addCentralForce oh wells.
It would have been nice to see a message when you try to access something that isn't on your scene.

I like Python and Lua also, and I am really liking the flexibility of LUA. I liike the syntax of LUA more than Python because with Python you have to indent correctly or else you will get errors. Not the case with lua. A statement is ended with the word "end."

I have a few tutorials on here about about programming in LUA.

like ulbex said, you can code in c++, follow the tutorial from the first link,
of course, you need a compiler installed on your system to compile the c++ code into a dynamic library.

I just can't stand Lua.

i would recommend sticking to lua for multiplatform compatibility:
you wouldn't have to recompile everything for windows/osx/android etc , and recompiling lua scripts is very fast
( very nice when you're designing a game )

despite it's ugly syntax , lua is apparently quite powerful
you can include multiple files via dofile command ( just like any other language )
and make classes

it's a good " game design oriented " language
