Asset loading

! Outside loop / need protect for run once

-- load model
loadmodel(path) -- path is string
-- load texture
loadtexture(path) -- path is string
-- load plane textured
loadplanetexture(texture_name.ext) -- create model plane with loaded texture

Input

btn / btnp

if btn(0) then
-- key w is down or gamepad left stick up
elseif btnp(1) then
-- key s is pressed or gamepad left stick down
end
-- btn(id) : key is down
-- btnp(id) : key is pressed
-- id=0 → key w / gamepad left stick up
-- id=1 → key s / gamepad left stick down
-- id=2 → key a / gamepad left stick left
-- id=3 → key d / gamepad left stick right
-- id=4 → key x / gamepad button x
-- id=5 → key c / gamepad button a

mouse

local x,y,btnl,btnm,btnr = mouse()
-- x = x mouse
-- y = y mouse
-- btnl = true/false mouse left button
-- btnm = true/false mouse mid button
-- btnr = true/false mouse right button

-- rotation in radian
-- scale > 0 , float multiply scale of model
