Hi, I trying to store a simple value in a local variable in the following Lua code.

the code:

!Lua 

-- get the L:var value
local val = varget("L:myVar","Number") 

val = val + 1 

-- store value in L:var
varset("L:myVar","Number",val)

 

This code is used for material scripting (P3D v4.2) but it's seems doesn't work.

Is it possible to store a new value in a local variable and re-read it  at each execution of this code?

Thanks by advance.

local val = varget("L:myVar","Number") 

should be

val = varget("L:myVar","Number") 

varset("L:myVar","Number",val) 

should be 

varset("L:myVar”,val)

Hello buckley, thanks for your quick answer, but I tried and it does not work, so I have a question, do I have to instantiate (L: myVar) before trying to get its value and if so where?

L variables are set to zero by default.. so the first varget should get you zero.

You can set it:

varset("L:myVar",0)

This varset statement has two different quote marks... " "

Could be a problem if copied/pasted

My bad. I copied and pasted OPs text and didn’t notice the different quotes. 

@bokdany make sure you correct that in both statements.

Looking at it again zoomed, I think the second quote came from my iPad in the reply box. In any event, just type them both correctly in your text editor.

Thanks alot for your replies, but  i think that i have a another kind of problem because i did many different try without results,   this script is called by a material who normally can access to local variables but its seems that i can read and write within some material variables and some simulation variables but not in local variables. I precise that i use P3D v4 with sdk 4.4.16.27106.
