but I'm not sure how to turn the first set of data into a gm object with...

tj_object(...key_value_pairs)

does anybody know how to use this extension?

There is a blog post here with usage examples: https://yal.cc/gamemaker-tjson/
and a pretty comprehensive manual here: https://yal.cc/r/17/tjson/

The best person to contact regarding an extension is the author, but that's usually for problems and issues with it rather than 1 to 1 tuition - that's what they write the manual, documentation and provide examples for.

However I'm sure YAL would give you hand if you reached out to him, he's a good guy.

ya I read both of those but I still don't understand how to create a object out of decoded data

I think you might be misunderstanding what TJSON does (or I've read you wrong myself!) -- TJSON is an alternative to the native json_encode / json_decode functionality that allows you to load/store/manipulate JSON data without having to worry about the data structure management that the native functions require (keeping track of ds_maps/ds_lists and ensuring they are properly destroyed, etc).

TJSON does not offer any way to create a GM Object out of the decoded data inherently; you'd have to do that yourself. At it's simplest, you would supply that JSON data as a string to pass into the tj_decode function, after which you would make use of the tj_get/tj_set functionality to read/write the individual key->value pairs.

For example:

/// Within an event of a GameMaker Object...
var json; // You'll need to establish how to load in the JSON data yourself, whether that be from a file or hard-coded directly in the script
data = tj_decode( json );

// Retrieve values
name = tj_get( data, "Name" );
flags = tj_get( data, "Flags" );

// Set values
tj_set( data, "Width", 4);
tj_set( data, "Height", 4);

thankyou @Arconious I will try it out
