Keep me updated if you need anything else.

Yep

So actually I forgot something

Okay real quickly, do you have a button that brings you from menu to game?

Okay so then are you going to have those checkboxes inside the Menu script?

And does the main menu scene have its own script?

Okay so you know how you can attach a script to a gameObject? Do any of your gameobjects have a main menu script attached to them?

Or do you just have one script for your whole game

Okay, so splitscreen is attached to the splitscreen gameObject?

Okay the easiest way I can think of doing this is making an empty object in your Menu scene and calling it MenuManager or something. I don't work much with the actual Unity interface and I do more scripting so I haven't done it through there before.

Okay and it has a script attached I am assuming?

Okay if you click MenuManager, the only thing it has attached is a script? I

I'll show an example

Except instead of GameManager you would have MenuManager up there

It is a script?

Okay so there are two parts to your splitscreen problem, the first part is making those booleans true and being able to access them, and the second is when they are true making the game splitscreen.

So for the first part

Make an empty gameobject in your menu and just call it MenuManager

Just right click and Create Empty

And just to make it easy did you call it MenuManager without spaces and with those capitals?

Okay so now this is the way I would do it, click on MenuManager on the left and on the right click Add Component and Add Script

New Script

and Call it MenuVariables

or something like that

Give me a min to do something irl brb.

Okay so I just remembered a way to do it, do you have a function for your button that loads the other scene?

when I had that thought and looked it up ppl said it wouldn't work

Back when I was doing something similar

Ok so in that buttons function you should make a playerpref which is just a way of saving settings which is perfect for this situation.

The way you do it is you have an if statement that you can just copy il type it out.

If(vertical)
{
PlayerPrefs.setInt("verticalSplitScreen", 1);
}

If(horizontal)
{
PlayerPrefs.setInt("horizontalSplitScreen", 1);
}

I believe it would be

Let me look into it for a second

My bad

Il fix it one second

I fixed it above

That goes in your button script that changes the scene and it has to be before the line that changes the scene.

You want that in the button that makes it go from Mainmenu to game

Okay so you have a button that when you press it goes into the game

So then do you have a function that changes the scene?

Can I see it?

Oh In unity?

Like the unity app?

Okay, then remember that script that you made

Yeah so in there make a new function below start and update

So public void splitScreen

Or whatever you want to call jt

Then in that function put that script I gave you

With the playerprefs

Yeah remove it from there

Yes

So then in thag button on click in unity add a plus

And drag in your empty objecy

With the global variables attached

Okay

And then that little box add the choose the function that you just made

Whatever you called it

Right

You need to add to the top

One sec

Oh capitalize Set

SetInt

Sure I guess

You forgot the brackets

{}

You need an open bracket at the end of line 23 and 28 after the if

And close brackets on 27 and 33

Yes

Okay now in your button

Yes

Add the empty gameobkrct

Yes

Okay now you need to make your check box work

The vertical and horizontal

Checkbook

Box

So you need to make it so that when you check it it makes it true. When you check horizontal the bool horizontal becomes true.

Ok how did u do it

Can I get a pic

Just to make sure

Lol

Yeah that is waytoodank

Okay perfect and now in the unity inspector did you make it so that oncljck do thosd?

Okay also not fully sure how checkboxes work but will it unxheck the other if they check horizontal

If not u might have to add a line of code to fix that

Okay

Okay now try to apply it and see if it works

To do this

Go to your game scene

And do you have a gamemanager?

Like menumanager?

So then just make an empty object called GameManager

Add a script component and just call it GameManagerScriot

Script

Then inside of it inside of Start add the code for resizing camera

Okay

So the code should be at the beginning something like this

Yes so like this

Horizontal = PlayerPrefs.GetInt("HorizontalSplitScreen");

Then same for vertical

Then below that do an if statement

If (horizontal == 1)
{
Resize camera
}

And same for vertical

Any qs?

Before you go?

Oh also its not HorizontalSplitScreen it has a lowercase h

Also at the top I think you need to declare Horizontal and Vertical to be variables so

Private int Horizontal;
Private int Vertical;

You need to set horizontal = to the playerprefs.getint

same for vertical

Okay and for changing the res

So right now you just have

PlayerPrefs.GetInt

Yes

And also for vertical

Okay now for the camera

Did you add the private int horiz and vertical?

To the top?

Okay now add one more for the camera

I believe it would be private Camera camera;

Yes, it might be Camera instead of GameObject I've never worked with them but yes

Also why do you need 2? So thag one is for the left or top and one is for the right or bottom?

No game object is the type of variable

Okay

For example if I have button I don't do private gameobject buttons1 and 2

I do
Private button buttons1 and 2

Yes

Is it transform?

OkY

So then whay you want to so is remember those two ifs

In the horizontal one you have one camera on top and one on bottom right?

Okay so I am trying to look this part up because I don't play with cameras often

Maybe I'm not fully sure

But you want to make the camera's y divide by 2 for both cameras.

And move camera2 down by the y value of camera2.

Yeah seems like it

Oh the viewport rect?

Yeah I don't touch cameras often as I said

Then you would just play with the values

Okay try it out and see how it goes

See you!

If something is wrong dm me

So I see it.

solemn flower Nov 21, 2021, 1:38 AM

Okay

Yeah I got that

Just move it back into the if(horizontal == 1){don't forget these brackets}

Okay now test it

Also real quick add a Debug.Log

after your two playerprefs

that has horizontal + vertical in it

just put (horizontal + vertical)

with the plus

that way it should print 1 and 0 or 0 and 1 in the console

unless none are selected then it would print null or something

no quotes

they are variables

quotes for strings

Looks good I think.

except

the Debug.Log

after the playerpreft

playerprefs

or it will juts give void

What do you mean

stuck on update

Okay one sec

Okay send me the script with the two checkboxes

When you click the box for vertical does the Debug.Log "void vertical is activated" go?

Does it print in console?

What do you mean by star

like turn on the game?

Yeah so both become unchecked?

do you want it to save?

Thats doable

do you mean play in unity

Maybe your menu has a play button

Okay but thats supposed to be like that

if you want it to save you have to do that, unity by default won't save that

so you have to check it again correct?

it being checked

By default when you click play both will be unchecked

If you want it to save its pretty easy to do that

So if I'm getting this right

you want it to save the selection

even when you unplay and play

In that case, just add something to the start

that says

Okay I see what you mean

Oh i see

Okay

Yes in your start function add something for it to load what you had checked

Right now it just saves

you need to put

if(PlayerPrefs.GetInt("horizontalSplitScreen") == 1)

{
//Code for checkbox on horizontal being checked.
}

if(PlayerPrefs.GetInt("verticalSplitScreen") == 1)
{
//Code for checkbox on vertical being checked.
}

I believe in your situation the code for checkbox being checked would just be
horizontal = true;
or
vertical = true;

Does the box check now?

When you go back

Okay it probably has something to do with the horizontal = true part

Just to be completely sure that this is a logic error, I'm going to have you change the way it works a little bit.

So instead of having the function attached to the checkboxes

Can you send me a picture of an example

I can't really understand what you mean by it

Oh I believe I know one of the issues

The PlayerPrefs that you are doing

it saves between games

so you need a spot somewhere where it will just reset it when they reopen the game

Okay so that is a picture of being not in the game

Okay try to check horizontal

then stop the game and start it again

it should have horizontal checked then

And its horizontal right

Yeah I know why its happening I think

Can I get your current code for your MenuVariables script

Lmao

using System.Collections;
using System.Collections.Generic;
using UnityEngine;

public class MenuVariables : MonoBehaviour
{
    public bool horizontal;
    public bool vertical;
    // Start is called before the first frame update
    void Start()
    {
        PlayerPrefs.SetInt("horizontalSplitScreen", 0);
        PlayerPrefs.SetInt("verticalSplitScreen", 0);
    }

    // Update is called once per frame
    void Update()
    {

    }
    public void splitScreen()
    {
        //Checks if horizontal or vertical is enabled in the first frame of the game
        if (horizontal)
        {
            //Cameras Horiontal orientation
            PlayerPrefs.SetInt("horizontalSplitScreen", 1);
            Debug.Log("Horizontal Splitscren Set");
        }

        if (vertical)
        {
            //Cameras vertical orientation
            PlayerPrefs.SetInt("verticalSplitScreen", 1);
            Debug.Log("Vertical SplitScreen Set " + vertical);
        }

    }
    public void horizontalTrue()
    {
        horizontal = true;
        vertical = false;
        Debug.Log("void Horizontal is activated " + horizontal);

    }

    public void verticalTrue()
    {
        vertical = true;
        horizontal = false;
        Debug.Log("void vertical is activated");

    }
}

Copy and paste that into your code

instead of what you have

So just replace what you have now with this

Good now?

Okay

Isn't it supposed to automatically check it off?

So basically you want it to stay checked between games?

In unity does it say vertical is checked

and horizontal isn't?

And if a player goes from the game back to menu vertical is checked

what if none are checked

then what does it do

Okay

Then can I get a screenshot of both checkboxes in unity

The gameobjects

in unity interface

to the right

So i'm talking about the inspector

not the game

except click on the horizontal toggle and take an sc of the right

and vertical

Okay I'm going to fix up the code real quick to make it more dependant on script as opposed to the inspector

using System.Collections;
using System.Collections.Generic;
using UnityEngine;

public class MenuVariables : MonoBehaviour
{
    public bool horizontal;
    public bool vertical;
    public Toggle horizontal;
    public Toggle vertical;
    // Start is called before the first frame update
    void Start()
    {

    }

    // Update is called once per frame
    void Update()
    {

    }
    public void splitScreen()
    {
        //Checks if horizontal or vertical is enabled in the first frame of the game
        if (horizontal)
        {
            //Cameras Horiontal orientation
            PlayerPrefs.SetInt("horizontalSplitScreen", 1);
            Debug.Log("Horizontal Splitscren Set");
        }

        if (vertical)
        {
            //Cameras vertical orientation
            PlayerPrefs.SetInt("verticalSplitScreen", 1);
            Debug.Log("Vertical SplitScreen Set " + vertical);
        }

    }
    public void horizontalTrue()
    {
        horizontal.isOn = true;
        vertical.isOn = false;
        Debug.Log("void Horizontal is activated " + horizontal);
    }

    public void verticalTrue()
    {
        Debug.Log("void vertical is activated");
        vertical.isOn = true;
        horizontal.isOn = false;
    }
}

Try that maybe?

And make sure to add your toggles to the gameObject

drag them in

Add
using UnityEngine.UI;

to the top

where you have all of the using

using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using UnityEngine.UI;

What line

never mind

At the top

where it says public toggle

make it horizontalToggle instead of just horizontal

and verticalToggle

I forgot that you are already using horizontal and vertical

public Toggle horizontalToggle;
public Toggle verticalToggle;

Its okay, just change those two lines up top

And see how it work

one sec

in your two functions horizontalTrue and verticalTrue

add Toggle to each of the horizontal and verticals

so they become horizontalToggle and verticalToggle

.isOn

go to your two functions at the bottom

yes

Working?

using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using UnityEngine.UI;

public class MenuVariables : MonoBehaviour
{
    public Toggle horizontal;
    public Toggle vertical;
    // Start is called before the first frame update
    void Start()
    {

    }

    // Update is called once per frame
    void Update()
    {

    }
    public void splitScreen()
    {
        //Checks if horizontal or vertical is enabled in the first frame of the game
        if (horizontal.isOn)
        {
            //Cameras Horiontal orientation
            PlayerPrefs.SetInt("horizontalSplitScreen", 1);
            Debug.Log("Horizontal Splitscren Set");
        }

        if (vertical.isOn)
        {
            //Cameras vertical orientation
            PlayerPrefs.SetInt("verticalSplitScreen", 1);
            Debug.Log("Vertical SplitScreen Set ");
        }

    }
    public void horizontalTrue()
    {
        horizontal.isOn = true;
        Debug.Log("void Horizontal is activated ");
    }

    public void verticalTrue()
    {
        Debug.Log("void vertical is activated");
        vertical.isOn = true;
    }
}

Copy that

Wait

Okay good

Hmm that means that it is looping but not sure why

Ok try the code again above

I edited it

yes

It might be looping it for some reason

Oh wait I know why

yes

Try that first

if it doesn't work then I'll try my fix

Okay

Ik why

its because you have the function saying if the box is checked then check the box

I'm just dumb

Remember you have that onclick

so if it is clicked then it will check it

One sec let me think about it

using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using UnityEngine.UI;

public class MenuVariables : MonoBehaviour
{
    public Toggle horizontal;
    public Toggle vertical;
    // Start is called before the first frame update
    void Start()
    {

    }

    // Update is called once per frame
    void Update()
    {

    }
    public void splitScreen()
    {
        //Checks if horizontal or vertical is enabled in the first frame of the game
        if (horizontal.isOn)
        {
            //Cameras Horiontal orientation
            PlayerPrefs.SetInt("horizontalSplitScreen", 1);
            Debug.Log("Horizontal Splitscren Set");
        }

        if (vertical.isOn)
        {
            //Cameras vertical orientation
            PlayerPrefs.SetInt("verticalSplitScreen", 1);
            Debug.Log("Vertical SplitScreen Set ");
        }

    }
    public void horizontalTrue()
    {
        vertical.isOn = false;
        Debug.Log("void Horizontal is activated ");
    }

    public void verticalTrue()
    {
        Debug.Log("void vertical is activated");
        horizontal.isOn = false;
    }
}

Try that

And if it doesn't work I have a rewritten version that should

yes

after u copy that code

Okay then this should work

using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using UnityEngine.UI;

public class MenuVariables : MonoBehaviour
{
    public Toggle horizontal;
    public Toggle vertical;
    // Start is called before the first frame update
    void Start()
    {

    }

    // Update is called once per frame
    void Update()
    {
        if(horizontal.isOn)
        {
            vertical.isOn = false;
        }
        else
        { 
            horizontal.isOn = false;
        }
    }
    public void splitScreen()
    {
        //Checks if horizontal or vertical is enabled in the first frame of the game
        if (horizontal.isOn)
        {
            //Cameras Horiontal orientation
            PlayerPrefs.SetInt("horizontalSplitScreen", 1);
            Debug.Log("Horizontal Splitscren Set");
        }

        if (vertical.isOn)
        {
            //Cameras vertical orientation
            PlayerPrefs.SetInt("verticalSplitScreen", 1);
            Debug.Log("Vertical SplitScreen Set ");
        }

    }

}

This gets rid of the functions

so make sure you get rid of them in the editor

and also go to edit in unity

and at the bottom

clearAllPlayerPrefs

Just go to each of the toggles

in your unity

and on the right

click minus

Ok one more time just so I am getting this right, what happens is that vertical is checked

and when you check horizontal it checks both?

did you do edit> clear playerprefs?

Let me see the other code

that has the splitscreen

probably

quick question is it a 2d or 3d

I'm going to try to recreate your project

Not sure why but unity is giving me hella errors when I load it

You could try that

you need the = 1 to be out side the paranthesis

and its ==

because you are comparing

= is setting the value to

also you need a parenthesis around the whole Player prefs

the == is outside too

PlayerPrefs.GetInt is a function

So it runs the function and sees if it gets 1

if (PlayerPrefs.GetInt("horizontalSplitScreen") == 1)

The parenthesis is for the if

If it was without the parenthesis if would treat it like

if PlayerPrefs.GetInt("horizontalSplitScreen")

then == 1

and it would be like why is there just a random == 1

if ( ) is true then run this

so if (Playerprefs value is 1) then run this

so if (PlayerPrefs.GetInt("horizontalSplitScreen") == 1)

yes

Yeah I'm testing it

Just wonderwing

When does splitscreen run

When you click play?

the function

Okay

Okay I'm asking why you have a splitscreen function

does it actually run

Okay

got it

I'm trying to rewrite it to make it simpler

Okay then

Oh shit

Dude

I literally remember saying how to fix this

before any of this was started

I was saying like in the start function before all of these lines put in PlayerPrefs.SetInt("blah", 0) for both

then I forgor 💀

Does it still work if you have both unchecked though?

Like if you have both unchecked will it make a normal camera

Its okay not too hard

Just hide the camera instead of deleting

and do the rect transform just with (0, 0, 1, 1)

So it would be cam1.rect = new Rect(0f, 0f, 1f, 1f);

cam2.active = false;

So where it says if (vertical == 1) and if (horizontal == 1) in your Gamemanager below it just add this and you literally are done

if (horizontal == 0 && vertical == 0)
{
    cam1.rect = new Rect(0f, 0f, 1f, 1f);
    cam2.active = false;
}

Yeah np

I think they get auto deleted

but if you just paste that above you can be done

it goes after the horiz and vert if statements in gameManager on line

38 ish

Okay

solemn flower Nov 21, 2021, 3:58 AM

Okay

Why didn't it work

You can still do it like that

Here, just do it something like this

In your MenuManager make a function

public void Singleplayer()

and inside of it put the line

PlayerPrefs.SetInt("singleplayer", 1);

and in your MenuManager start function also put PlayerPrefs.SetInt("singleplayer", 0);

So in MenuManager

Start:

PlayerPrefs.SetInt("singleplayer", 0);

New Function named Singleplayer:

PlayerPrefs.SetInt("singleplayer", 1);

Then finally, in GameManager on your other scene

At the bottom of Start:

if (PlayerPrefs.GetInt("singleplayer") == 1)
{
    cam1.rect = new Rect(0f, 0f, 1f, 1f);
    cam2.active = false;
}

And in the other functions you need to add that it cannot be singleplayer for splitscreen.

So in the end it would look something like

void Start()
    {
        
        horizontal = PlayerPrefs.GetInt("horizontalSplitScreen");
        vertical = PlayerPrefs.GetInt("verticalSplitScreen");
        singleplayer = PlayerPrefs.GetInt("singleplayer");
        Debug.Log(horizontal + vertical);

        if (vertical == 1 && singleplayer == 0)
        {
            //Resize vertical
            Debug.Log("Vertical");
            cam1.rect = new Rect(0.5f, 0f, 0.5f, 1f);
            cam2.rect = new Rect(0f, 0f, 0.5f, 1f);
            //                    x   y     w    h
        }



        if (horizontal == 1 && singleplayer == 0)
        {
            //Resize horizontal
            Debug.Log("Horizontal");
            cam1.rect = new Rect(0f, 0.5f, 1f, 0.5f);
            cam2.rect = new Rect(0f, 0f, 1f, 0.5f);
            //                    x   y     w    h
        }
        
        if (singleplayer == 1)
            {
                cam1.rect = new Rect(0f, 0f, 1f, 1f);
                cam2.active = false;
            }
    }

Note I also added a singleplayer variable.

and I also added singleplayer to the other if statements.

I forgot

at the top make singleplayer an int

so above start

yes

should work

enabled

instead of active

it should work

Okay yeah

that should fix it

lol

it means you understood

so thats good

Okay

cursors?

Oh I see

Let me see the code that manages the controls

like the cursors

it is gameObject.enabled = false;

So can I see the cursors scrip

Or did you use Unity Movement system

Yes

So you used the movement system?

Yeah sure

Do the cursors actually move?

crosshair

okay then yeah just turn off the image

It should be a canvas

not just a gameobject

its in UI > canvas

Then in your GameManager

add a line to the singleplayer if in start

and a variable to the top

public Canvas cursor2Canvas;

So first add the variable

to the top

public Canvad cursor2Canvas;

then in the if statement that is if (singleplayer == 1)

just add canvas.enabled = false;

and drag in the cursor2's canvas

yes

Yep

Okay

are you talking about the Player2

or the cursor

Okay and what is player2

is it an image

Oh like if you look there from player1

you can see player2

its a human

send me a picture of the inspector

the one on the right

when you click player2

the gameobject

Okay

it would be SetActive = aflse

false

instead of enabled

🍦 bing 🥶 chilling

what is the line of code

ooh

it isn't SetActive = false

it is gameobject.SetActive(false);

its a function

not a property

Yeah a canvas

is what you put the cursors into

Wait what are you trying to do again

just make it simple and make a variable

public gameobject cursor2;

drag in the cursos

and SetActive(false);

Ok then click the arrow to the left of canvas 1 and canvas 2

and take a screenshot of the whole thing

so i can understand

Okay

I get it

so real quickly

a canvas is like an artists canvas

its where you make stuff for UI

so you have two canvases, one for player 1 and one for player2

Yea

okay

so are these canvases in the same place as GameManage

same scene

Okay so in GameManager

add two variables

public Image cursor1;

okay

public Image cursor2;

then in the vertical if statement

wait actually

you want them to be canvases

not images

so public Canvas cursor2

yes

;

I think so

it could also be SetActive(false);

try both

you have two canvases

you have a game object

and in the game object you have two canvases

and in each canvas you have a cursor

image

so drag the canvases

ah yes

Oh okay

in that case Cursorpart are your canvases

so drag those in

Oh what

Why

Oh okay

Then in that case make the variables the gameObject

public GameObject cursorPlayer1;

public GameObject cursorPlayer2;

solemn flower Nov 21, 2021, 5:25 AM

Okay

So then in vertical if you want to adjust the cursors x y width height

Yeah

you probably want

cursorPlayer2.position = new Vector3(x, y, z);

You can use rect

yeah sure

Not sure what you mean.

You need to move the cursors yes

then just use rect on the game object

yeah but the gameobject contains the images

oh then just use vector

So what if it moves all images

isn't that the point

The gameobject contains all of the images needed to make 1 plus correct?

and you have two gameobjects?

so then what is the problem?

That doesn't matter

It'l keep that

Thats on the image yes

not the gameobject

So cursorPlayer2.rect = new Rect();

first try putting random digits to make sure that you don't get an error

between 0 and 1

first do vertical

So try cursorPlayer2.rect = new Rect(0, 1, 1, 1);

or something

Just make sure you can do rect on a gameobject.

yes

one sec

Oh yeah

Okay

then you have to use Vector3

so it would be

cursorPlayer2.position = new Vector3(x, y, z);

i don't think you need the floats

it should take integers

btw the f means float

so any number with decimal

my bad

yeah

Yes

Okay and did you change the xyz

yeah

why would it change

if you didn't give it a value to change to

just mess around with it until it works

try 2 2 2

see what it does

Are you sure that you are actually making the if statement true

like are you going into vertical mode if it is in the vertical if

wait

check the transformations

what is the xyz exactly now

just like you did above

Yeah

Okay just make sure that the values for the gameobject aren't changing.

Also add a Debug.Log(cursorPlayer2.transform.position);

then you probably want a foreach loop

try this

foreach (Canvas c in cursorPlayer2)
{
    c.transform.position = new Vector3(2, 2, 2);
}

you can try that

And if that doesn't work

foreach (Canvas c in cursorPlayer2)
{
    foreach (Image i in c)
    {
      i.transform.position = new Vector3(2, 2, 2);
    }
}

Try this first

then yeah you probably want to do your way

lol

you put this instead of the cursorPlayer2.transform.position

Eh just try it lol

just for fun

yea

lool

Ok just do your idea

that was just a dumb way lol

oh what you need is an IEumerator class

that is derived from MonoBehavior

but also derived from your function

and then compiled into a class

that returns an IEun

you getting this

I'm kidding

just do your mspaint thing

or if you want send it over il do it in photoshop

okay

send the parts

what resolution u want

yea

or do you want a new crosshair

Okay so a dot

eeh

Want it like this or more a plus

transparent version

Two optios

Alr its 1.21am here

I'ma go sleep

Need anything else b4 i go?

yea

probably

not fully sure what the code is

can i see the code

Just use Vector3

so transform.position

or whatever it was

= new Vector3(x,y,z);

you put -450

rect has a max of 1

cam1.rect = new Rect(0f, 0.5f, 1f, 0.5f);

but why it just rect there

Ok whatever

Just try it

nah the recttransform

but u can try vector 2

idk

yeah thats why I think vector easier

btw z stays the same I think

why can't u use image

instead of rawimage

just make it a sprite

probably

Yeah but u want it like this

imageVariable.GetComponent<RectTransform>().anchoredPosition = new Vector3(xPos, yPos, zPos);

nah you dont keep the imageVariable

cursorPlayer2 is the imageVariable

works?

okay

gas

can i close

solemn flower Nov 21, 2021, 7:58 PM
