du_render_script_library #

A library to build renderscript in boards without writting it as a full string

The goal of that lib is to make RenderScript easier to write and read when written un control units and not directly in screens.

Project status #

This project is currently in developpement and not finished yet.

I'm currently looking for feedbacks and ideas to improve it and fix some limitations like how to render a function or loop or condition in the render script.

How to use it #

Paste all the content of the library (prefer the minified version) at the start of your script in a control unit in game and then you can use it like this:

local script = setmetatable({},RenderScript)
local MyFirstLayer = script:createLayer()
script:addBox(MyFirstLayer,0,0,100,100)

if not script:isTooLong() then
    script:sendToScreen(screen)
else
    system.print("WARNING: Script too long!! Length is actualy " .. script:len() .. " / " .. script:getMaxSize())
end

Code before #

Code was all formated as a string and was hard to read, write and debug

local script = [[
    local MyFirstLayer = createLayer()
    addBox(MyFirstLayer, 0, 0, 100, 100)
]]

screen.setRenderScript(script)
