What’s the best way to use/name variables in functions and behaviors so you don’t risk conflicting with the calling projects variables? I’ve seen the use of a double colon in between the function name and variable like “circles::x” but I haven’t seen any mention of the double colon in any documentation.
You can make properties in behaviors hidden. Should I use nothing but properties in behaviors instead of variables?
Underscores or CamelCase are your best bet.
Samples
GDevelop.MyVariable
GDevelop._my_variable
In behavior you can mix both properties and variables is perfectly fine.
Use properties when you see that a variable is repeating a lot in your code so maybe is best to turn that variable into a property.
thanks. I just had a problem between my own similar functions that was being caused by the same variable. Luckily, I found it fairly quickly. What about the double colon like box::width ? What are they designed for?
The double colon is referred to as a scope resolution operator. It allows you to access properties or methods/functions of a class (or behaviour in this case).
