Do you mean draw3d? Draw3d is a hook that is called when the 3d objects are drawn. You can use the functions:
draw_capsule(x,y,z,length,radius,rotx,roty,rotz),
draw_sphere(x,y,z,radius) and
draw_box(x,y,z,width,height,depth)
in this function to draw 3d objects on the screen. Look in worldbuilder.lua to see it used in practice or here's a quick example

do
	local function on3d()
                draw_sphere(0,0,1,1)
        end

	add_hook("draw3d", "draw3dtest", on3d)
end

Ok, I've found another field called get_body_info.rot which wasn't in the sdk example. I also found a function set_body_rotation, but it doesn't seem to do anything, so I guess this feature is planned but not implemented yet.

.rot was new fixed 3.1, so it hasn't been added yet.
And set_body_rotation as you said probably is planned for the near future.

.rot has actually been around since 2.7 or so, but it was broken between something like 3.04 and 3.06, but it's back to its old behavior.

It currently returns a rotation matrix with named fields r0, r1, r2 ... r15.

Here's some code from an API I'm developing that uses it. Maybe this will help.

Can lua export game settings into notepad and save them in the scripts folder?

Same with moves from a replay?

I tried to add upon RiCh's emote script but it has an error loading

local function keydown(key)
if(key == 44) then
run_cmd("em Where is your god now!?!")
end
if(key == 46) then
run_cmd("em I fail")
end
if(key == 109) then
run_cmd("em Death by spritecat")
end

if(key == 110) then
run_cmd("em Fresh blood")
end
if(key == 305) then
run_cmd("em What are you looking at?")
end
if(key == 303) then
run_cmd("Duck and cover!")
end

echo("Script by RicH")
echo("Have a nice day!! ")
echo("Tested by RicH, Blueshoes, and others who were shocked with the rapid emotes")
echo("m,.")

add_hook("key_down", "keypressdown", keydown)


Whats wrong with it?

Check stderr.txt for clues!

(10) : warning C7532: global function exp requires "#version 110" before use

Thats what it says i have no idea what it means

you need to put another end after the last end..
Fixed code:

local function keydown(key)
    if(key == 44) then
        run_cmd("em Where is your god now!?!")
end
    if(key == 46) then
        run_cmd("em I fail")
end
    if(key == 109) then
        run_cmd("em Death by spritecat")
end

    if(key == 110) then
            run_cmd("em Fresh blood")
end
    if(key == 305) then
        run_cmd("em What are you looking at?")
end
    if(key == 303) then
        run_cmd("Duck and cover!")
end
end

echo("Script by RicH")
echo("Have a nice day!! :)")
echo("Tested by RicH, Blueshoes, and others who were shocked with the rapid emotes")
echo("m,.")

add_hook("key_down", "keypressdown", keydown)

To end the keydown function
