Does anyone know any good Youtube channel or website where I can learn to script? I really want to get into making mods and stuff like that.

Unfortunately there isn't any complete tutorials or documentations out there. Most people learn by reading Treyarch's scripts and piecing bit of code until the compiler accepts it. If you have any experience with other actual programming languages though you shouldn't have a hard time learning it.

Yes, look at 3arc code and piece together, if you wanna know useful functions or any at all http://ugx-mods.com/script/ also, start simple with I don't know look at how to make something move from one place to another, which is really simple also here, https://confluence.ugx-mods.com/display/UGXMODS/Script this has a couple things to help like a guide and helpful functions.

The UGX scripting tutorial isn't very accurate nor easy to read or understand. For example:

Variables store info.

While this is true for primitive data types(such as an integers, booleans, etc), objects are referenced. The difference is that instead of simply holding a value, the variable instead holds an object that has properties associated with it, can be referenced by other functions, and can be deleted at any time.

If you wish to access one variable from multiple functions, there are two approaches. You have to either pass that variable into the function, or you have to declare that variable as 'global'. The CoD syntax for a global variable is to store said variable inside the 'level' variable using the dot operator.

Dot Operator: A variable within a variable (inception!).

You aren't actually declaring as a global, just associating the value to the global object as a property.

This only applies to objects You CANNOT give a primitive value properties.

etc.

CodScript is like many other object oriented languages. Here are a few places to learn more for free. I prefer python myself, but to each their own. Learning a higher level language first may give you a different view than those that learn something like C first, btw, but it never hurts to look at something from a different view, in my opinion.

Codecademy
Udacity
edX
Coursera


I also added this for beginners. Scripting Basics
And there is this site CodScript
