global variables? Topic is solved

[Lukas]

Is there a way to save something to a global variable?

For example, can I create a button with 2 actions:

action1:

Code: Select all

GLOBAL myglobalvar = 4

action2:

Code: Select all

name[1] = "HELLO"
name[2] = "EVERYONE"
name[3] = "AU"
name[4] = "REVOIR"

PRINT(name[myglobalvar])

To make the button print "REVOIR"?

If not, is there any other way to achieve something like this?

Also, is there a cleaner way to create arrays/tables or even structs in George? Or the name array above the only way?

Hi Lukas,

Took me a bit to understand, but George doesn't have software-global variables.
Variables in George are "restricted" to their own script and can't interact with instructions from another script.

However, I found a workaround for this, as I needed it years ago :p

You can use the command tv_WriteUserString to save a variable to your User Config, then use the command tv_ReadUserString to retrieve it.

In your case, the script could be written like this:

Action 1:

Code: Select all

section = "globalGeorge"
name = "globalVariable"
tv_WriteUserString section name 4

Action 2:

Code: Select all

name[1] = "HELLO"
name[2] = "EVERYONE"
name[3] = "AU"
name[4] = "REVOIR"

section = "globalGeorge"
name = "globalVariable"
default = "not found"
tv_ReadUserString section name
val = result

PRINT(name[val])

And in theory it should work.

Also, is there a cleaner way to create arrays/tables or even structs in George?

Unfortunately, not possible.

Ah! I remember using tv_WriteUserString a long time ago, had to see the function to remember it. That should work for my problem. Thank you!

This is a thread that discusses tv_WriteUserString and tv_ReadUserString and also discusses a technique callsd "StringPacking" that you might find useful.


Also note the last entry in that thread shows a way to create a script for packing and unpacking values in an array, which might work for you.

Very interesting Svengali, I'll try and wrap my head around that code. My George is very rusty, its quirks are quite hard to read and understand if you haven't touched it in a while. Thanks for pointing me in that direction!

You can also store variables "per project" which can come handy https://wiki.tvpaint.com/index.php/Tv_W ... jectString

Also, you can write/read text anywhere in the clip dialogue/notes textboxes, project infos, and you can write text files with george

Ah, good to know. Thanks!
