New to LUA need help with code[solved]

[vshubh123]

Hey guys
I was just wondering if someone could provide me a codesnippet to display the values of variables in a Hud label, i.e FPS or mouse location

I have the following code below that does not work:

Code: Select all

   local variable  = 12;
        hud.setLabelText( hud.getComponent ( application.getCurrentUser ( ), "Hud.display" ) , variable )

If I change the replace the variable and give it a static value of something like : "12" It works. Code below:

Code: Select all

hud.setLabelText( hud.getComponent ( application.getCurrentUser ( ), "Hud.display" ) , "12" )

I got the same Problem. Lua set your variable as an number. But you just can dislpay an String into the label. I was looking for an function to convert number to string and i didn't found one. Because i just need it for some tests into my game i sove this with an inelegantly solution.




local nVariable = 12;
local sString = " " .. nVariable;
hud.setLabelText( hud.getComponent ( application.getCurrentUser ( ), "Hud.display" ,sString);

I hope it helps.

Are you after the double dot string concatenation method?

Code: Select all

hud.setLabelText(hud.getComponent(application.getCurrentUser(), "Hud.display"), "Speed: "..nVar)

much cleaner with string.format:

Code: Select all

hud.setLabelText( hud.getComponent ( application.getCurrentUser ( ), "Hud.display" ), string.format("%s", nVariable ) )
