Becquerel•2y ago

no if you can explain it on a call, you can explain it over ironic

avishy•2y ago

i just want to show my code not talk

public Point(Point another) { this.x = another.GetX; this.y = another.GetY; } this part doesnt work

Becquerel•2y ago

ok how does it not work

avishy•2y ago

idk it just syd error

Becquerel•2y ago

what's the error

avishy•2y ago

"Cannot convert method group 'GetX' to non delegate type 'Double'

Becquerel•2y ago

ok you see how in this line: double dis = Math.Sqrt(Math.Pow(this.x - another.GetX(), 2) + Math.Pow(this.y - another.GetY(), 2)); you're doing another.GetX() and another.GetY()?

avishy•2y ago

Becquerel•2y ago

do you see a difference between those and this.x = another.GetX;?

avishy•2y ago

no i need two x's

Becquerel•2y ago

the difference is the () after GetX if you just have GetX, that's the name of the function if you have GetX(), that's calling the function to make it do something and give you a result

avishy•2y ago

i know i want that tho

Becquerel•2y ago

public Point(Point another)
        {
            this.x = another.GetX;
            this.y = another.GetY;
        }

public Point(Point another)
        {
            this.x = another.GetX;
            this.y = another.GetY;
        }

? are you sure?

avishy•2y ago

yes

Becquerel•2y ago

but that's not working 😛

avishy•2y ago

yes that the problem? is* when i remove the () it make more errors

Becquerel•2y ago

yes... so you want to add the ()

avishy•2y ago

i did

Becquerel•2y ago

and?

avishy•2y ago

so instead of getX i do GetX() ?

Becquerel•2y ago

yes

avishy•2y ago

ok thank you

avishy•2y ago

if i do GetX in another part of the code will it be the same GetX as the last one?

Becquerel•2y ago

explain what you mean in a bit more detail please it will call the same function, but the object it calls it on may be different

avishy•2y ago

does the user need to put the X in the function twice? i mean, whenever i call the function does the user need to put a new X again?

Becquerel•2y ago

you don't have to put a new x in anywhere when you call another.GetX()?

avishy•2y ago

thats the question yes

Becquerel•2y ago

i don't understand your question - maybe give two examples of what you mean, one with 'putting in the X' and one without

avishy•2y ago

cs public double distanceToPoint(Point another)
        {
            double dis = Math.Sqrt(Math.Pow(this.x - another.GetX(), 2) + Math.Pow(this.y - another.GetY(), 2));
            return dis;
        }
        public double ThirdPoint(Point another)
        {
            double pthreeX = (this.x + another.GetX()) / 2;
            double pthreeY = (this.y + another.GetY()) / 2;
            return (pthreeX, pthreeY);
        }

cs public double distanceToPoint(Point another)
        {
            double dis = Math.Sqrt(Math.Pow(this.x - another.GetX(), 2) + Math.Pow(this.y - another.GetY(), 2));
            return dis;
        }
        public double ThirdPoint(Point another)
        {
            double pthreeX = (this.x + another.GetX()) / 2;
            double pthreeY = (this.y + another.GetY()) / 2;
            return (pthreeX, pthreeY);
        }

it calls the function twice but do i need to put the x twice too?

Becquerel•2y ago

i really don't know what you mean by 'put the x' are you thinking you could just write .Get() or something?

avishy•2y ago

no no, sorry english isnt my first language idk how to explain it

Becquerel•2y ago

fair enough, it's difficult do you mean the fact that there are two xs in this.x + another.GetX()?

avishy•2y ago

uhhhh no I don’t think so it’s probably nothing thank you
