Encode(String Save_Game_text, int key)

[YouGroove]

I don't want players to be able to cheat too easy just modifying a save file using plain text.

So having some Lua functions like

Encode(String Save_Game_text, int key)

Decode(String Save_Game_text, int key)

Would be helpfull.

until u can try this. i try xor but can not do, don't know if we have a bit class in lua.

if u stay/wrap in the byte range 0-255 u can overlap with a keyword.

the codeblock change some b to UPPER case ^^

 

function Script:Crypt(text)

out=""
b=0
for i =1, text:len() do
b=255-text:byte(i) -- range from 0 to 255
out = out .. string.char(B)
end
return out
end

 

-- MR
function Script:Start()

cam=Camera:Create()

end
--This function will be called after the world is rendered, before the screen is refreshed.
--Use this to perform any 2D drawing you want the entity to display.
function Script:PostRender(context)

context:SetBlendMode(Blend.Alpha)
context:SetColor(1,1,1,1)

local a= "ABCDEFGHIJKLMNOPQRSTUVWXYZ Hello ,. ÄÖÜäöü +- °!§$%&/()[]{}=?@"
context:DrawText(a,0,0)

local b=self:Crypt(a)
context:DrawText(b,0,15)

local c=self:Crypt(B)
context:DrawText(c,0,30)

end

function Script:Crypt(text)

out=""
b=0
for i =1, text:len() do
b=255-text:byte(i) -- range from 0 to 255
out = out .. string.char(B)
end
return out
end
