What's the error?

TOLOXI•4mo ago

Angius•4mo ago

That's because the method is a member of a different class

TOLOXI•4mo ago

yes i have it in another class

Angius•4mo ago

You can make that method static and reference it with class name Or keep it non-static and use an instance

TOLOXI•4mo ago

but if i make it public? would that work

Angius•4mo ago

Then... it will be available from outside of the class, yes

TOLOXI•4mo ago

how do i do that?

Angius•4mo ago

But still a member of it static modifier

TOLOXI•4mo ago

let me try that

TOLOXI•4mo ago

why do i get errors?

Angius•4mo ago

Static methods cannot reference non-static members I would recommend learning C# and object-oriented programming in general before jumping into Unity tbh

this is monogame

Angius•4mo ago

Still

im trying to learn it from here for a school project so it becomes easier but we bearly gor any good lectures

You're trying to learn swimming by jumping off a cruise ship in the middle of an ocean Start with $helloworld

Learn what classes are

TOLOXI•4mo ago

honestly im just trying to get this porject done then get more into coding since we bearly have anytime to learn or understand the classes

Angius•4mo ago

Then drop the idea of splitting your code up, it will make things easier Or use partial classes

TOLOXI•4mo ago

i have to split it into 5 diffrent classes to get a grade

Angius•4mo ago

Split this very code into 5 classes, or just use 5 classes? You need to treat each class as its own, distinct, thing With its own, distinct, properties and methods

TOLOXI•4mo ago

i do know that but the whole project has to be in 5 classes. my teacher did a similar thing where he put methods in other classes

Angius•4mo ago

For example, a Car class won't use methods from a Toaster class, it makes no sense, they're completely separate and orthogonal You can have some code depend on other code, yes

TOLOXI•4mo ago

and i cant ask for help since it would l ower my grade

Angius•4mo ago

A Car can make use of an Engine class Since an engine is a part of the car

TOLOXI•4mo ago

so it inhertis? inhertis from another class

Angius•4mo ago

But just splitting a car into LeftCar and RightCar makes no sense No, not talking about inheritance

TOLOXI•4mo ago

thats the thing im just trying to get to 5 diffrent classes so i can get a good grade even if its useless and i know its dumb to do that im just doing it for the school project

Talking about

class Engine
{
    public void Start(){}
}

class Light
{
    public void TurnOn(){}
}

class Car
{
    private Engine _engine = new Engine();
    private Light[] _lights = new[]{
        new Light(),
        new Light(),
    };

    public void Run()
    {
        _engine.Start();
        foreach (var light in _lights)
        {
            light.TurnOn();
        }    
    }
}

class Engine
{
    public void Start(){}
}

class Light
{
    public void TurnOn(){}
}

class Car
{
    private Engine _engine = new Engine();
    private Light[] _lights = new[]{
        new Light(),
        new Light(),
    };

    public void Run()
    {
        _engine.Start();
        foreach (var light in _lights)
        {
            light.TurnOn();
        }    
    }
}

See how Engine and Light are components of Car?

TOLOXI•4mo ago

yes i can see that

leowest•4mo ago

I mean u should have that easily, u have the player, u have the main game class. u have a screenmanager, u have a scene no?

TOLOXI•4mo ago

i have all of that

TOLOXI•4mo ago

leowest•4mo ago

those are all classes

TOLOXI•4mo ago

im just trying to get a method from a class to another class and have it still working but im getting an error

Angius•4mo ago

You can't just move things willy-nilly Each class has its own members Each is its own, unique and separate, microcosm You can have static members in class B and use them in class A, yes But that method will have no knowledge of anything from class A, ou will have to pass it some parameters You can have a method in class B be non-static, which means it's an instance method And that method can only be called on an instance of class B You can't just "move some methods" You can't move the "heat" functionality of an Oven into an UngaBunga

TOLOXI•4mo ago

if i change my varibles to Static isntead and make the method static in one class can i then use it in another class without it effecting my current code`?

Angius•4mo ago

If you make everything static you will have a pile of crap and not code

TOLOXI•4mo ago

thats the thing i dont get. if i have 5 classes and each class dosent know whats going on in the other class how can i make a game?

Angius•4mo ago

* Inheritance — Car inherits Vehicle * Composition — Car has an Engine Two ways Pick your poison

TOLOXI•4mo ago

it woudl be so much easier ifi made it into one class but that woudlnt be acceptale by the teacher i will look more into this and ask the teacher about it , maybe even get some help. But thank you for explaning it i really appreciate it
