Passing an array as an argument in VEX? / Looking for 1-to-1 tutoring.

[Ocelote]

Hi everyone!

 

I'm currently struggling with this: 

 

Is there a way of passing an array as an argument, fill it with integers and then return that array to be used by another function?

 

Something like this?

 

int pt_numbers_array[];

 

int create_points(vector v1; int array[]; int total_pts) {

 

        vector new_pos1 = v1;

 

        for (int i = 0; i < total_pts; i++){

 

            int pt1 =  addpoint(geoself(), new_pos1);

            array = pt1;

            new_pos1 += {0,1,0};

        }

        return array[]; 

        

}

 

create_points(@P,pt_numbers_array[],5);

 

 

Actually, this is not my only question. So, is it posible to get some personal VEX training with someone? I don't wan't to abuse the forum...

 

 

Thanks in advance.

You don't need to return it from your function. It's passed by reference so it will be modified. Run this in Detail mode:

#define PRINT(val, text) printf("numbers %s: %d\n", text, val)
 
vector CENTER = set(0, 1, 0);
int numbers[];
 
void AddPoints(const vector pos; const int maxcount; int refarray[]) 
{
    vector newPos = pos;
 
    for (int i = 0; i < maxcount; i++)
    {
        int currentNumber =  addpoint(geoself(), newPos);
        refarray[i] = currentNumber;
        newPos += {0, 1, 0};
    }
}
 
PRINT(numbers, "before");
AddPoints(CENTER, 3, numbers);
PRINT(numbers, "after");
