Return a vector from a getter

[p.roman]

Hi,

I'm not really familiar with the UnigineScript API, I wanted to know if there is a way to use a getter to return a vector, but syntaxes like :

int[] getArray();

seem wrong. Do you know how I can do it ?

Thanks !

Hi!
Unfortunately, you can't return use container as a function return type via UnigineScript directly.

Return Values

Values are returned with the help of an optional return statement. Any data type may be returned, except for vector, map, and enum.

As a solution, you can pass a container as a function parameter. You can read about passing containers as arguments in the documentation: https://developer.unigine.com/en/docs/2.5/code/uniginescript/language/functions?rlang=cpp#passing.

Passing Containers as Arguments

To pass a vector or a map as an argument, use a proper function declaration, as shown below:

Source code (UnigineScript)
void foo(int a[]) {
	a[13] = 321;
}

int arr[] = ( 1, 2, 3, 4 );
foo(arr);
