Crystal text

[hallow heron]

@robust yacht

[robust yacht]

good idea lol

thank you so much btw for all ur help, this has been a struggle for a good few hours lol

[hallow heron]

Umm is the list full of projectile?

[robust yacht]

no the list is instaniated prefabs

they just sit still when spawned it

[hallow heron]

And what does UpdateText look like?

[robust yacht]

    public void UpdateText()
    {
        s.AppendLine(crystal.crystalType[crystal.crystalType.Count - 1]);
        myText.text = s.ToString();
    }

[hallow heron]

So is it repeatedly adding projectile when you enter it or instant

[robust yacht]

ill give it another test and see

ah i see so i think it might be because i dont destroy the object instantly

imma turn of the 1 second delay and see

hmmmm

ok so what seems to happen is it will add 1 text, but then when i pick up another gem it will add loads of the pervious crystal name and then 1

So when i picked up the first one, it just had 1 speed

then the rest of the speeds appeared out of nowhere when i picked up the second

[hallow heron]

weird

You don’t have anything in the update right?

[robust yacht]

oh

in update i hate this

    void Update()
    {
        crystal.crystalType.ForEach(str => s.Append(str + " "));
    }
    public void UpdateText()
    {
        s.AppendLine(crystal.crystalType[crystal.crystalType.Count - 1]);
        myText.text = s.ToString();
    }

[hallow heron]

Did you still have the old code?

Ahh that’s why

[robust yacht]

ah

do i need that anymore

[hallow heron]

No

[robust yacht]

oh lolol

ok

sorry 😂

[hallow heron]

Hopefully that ends up being it

[robust yacht]

perfect, we got it working!

can i ask one final question

[hallow heron]

Sure

[robust yacht]

So now that I know it is storing these strings, how could i then translate these into bools for example so if i collect a jump crystal, i can add the buff

[hallow heron]

Oh so if you have the speed one, then it applies speed?

[robust yacht]

yes for the player

so like it increases the player by like 5 speed

[hallow heron]

It would be best to put it on the actual “speed crystal” but you can also use list.exists to see if a certain string exists in the list. It just has to search through the list every time to check https://www.geeksforgeeks.org/c-sharp-how-to-check-whether-a-list-contains-a-specified-element/

[robust yacht]

ah so for the first example, i would have to have seperate ones for each buff?

[hallow heron]

Wdym?

[robust yacht]

so in this example:

// C# Program to check whether the
// element is present in the List
// or not
using System;
using System.Collections;
using System.Collections.Generic;
 
class Geeks {
 
    // Main Method
    public static void Main(String[] args)
    {
 
        // Creating an List<T> of Integers
        List<int> firstlist = new List<int>();
 
        // Adding elements to List
        firstlist.Add(1);
        firstlist.Add(2);
        firstlist.Add(3);
        firstlist.Add(4);
        firstlist.Add(5);
        firstlist.Add(6);
        firstlist.Add(7);
 
        // Checking whether 4 is present
        // in List or not
        Console.Write(firstlist.Contains(4));
    }
}

[hallow heron]

It prints “True” because the list contains 4

[robust yacht]

ah so in my case, do i need to do the firstlist.add(1) and so on

or just put the list

because mine is a string

[hallow heron]

No, it’s just creating a new list of ints

As the example

[robust yacht]

ah

[hallow heron]

if(list.Contains(“Speed”))
{
AddSpeed();
}

or something

[robust yacht]

oh so i could literally just do a if statement

with list.contains

[hallow heron]

yeah since it returns a bool

[robust yacht]

beautiful, imma give that a go then

where does it return the bool?

[hallow heron]

in the if statement

for context:
bool someBool = (2 == 2); returns true
so someBool is equal to true

[robust yacht]

but i mean like normally you have to declare like public bool name

[hallow heron]

if(someBool)

[robust yacht]

so what is it if(list.contains("speed)) do

[hallow heron]

^ this works

[hallow heron]

it’s a return type method. Some methods return ints or bools and stuff. That one searches through the entire list to see if anything == “Speed” and returns true if it finds anything

[robust yacht]

ah so if its true, it does whats inside of the if statement

gotcha

[hallow heron]

void Start()
{
int value = 10;
int x = DivideHalf(value);
Console.Log(x);
}

int DivideHalf(int halving)
{
halving /= 2;
return halving;
}

//prints 5 to console

Example of a int return method

[robust yacht]

amazing it works

thank you so much for your help pumpkin, i really appreciate it, was a mega head scratcher for me

[hallow heron]

Glad to help 😅

[robust yacht]

@hallow heron sorry to ask again, this will be the final question, im trying to make it to where my player gets put to a position when a new scene loads, why cant i put my scene number in here?

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

public class ScenePlayerLoad : MonoBehaviour
{ 
        [SerializeField] private Transform player; 
        private Vector3 targetPosition; 

        private void OnEnable()
        {
            SceneManager.sceneLoaded += SceneLoaded; 
        }

        private void OnDisable()
        {
            SceneManager.sceneLoaded -= SceneLoaded;
        }

        private void SceneLoaded(Scene scene, LoadSceneMode mode)
        {
            if (scene == [0]) 
                player.position = targetPosition;
        }
}

[hallow heron]

are you trying to find if the scene is the first index?

[robust yacht]

Well i just put the zero there to see if it would work and it had an error on that square bracket

"invalid expression"

I am trying to check if its the boss fight scene, if so teleport player to position

[hallow heron]

I don't think you need the [0]

[robust yacht]

ah so i must of read the documentation wrong

is it a string u put there?

[hallow heron]

its of type scene instead of int

[robust yacht]

ah, what is it i need to replace it with for it to work?

[hallow heron]

scene.buildIndex == 0 checks if scene is scene 0

[robust yacht]

ah ok

Would i need to put the script on an object in the scene i want it to do it on?

[hallow heron]

int theLevel = SceneManager.GetActiveScene().buildIndex;

[robust yacht]

what does this do?

[hallow heron]

if(theLevel == 0)

GetActiveScene returns the currently loaded scene. build index is a property of a scene that tells you the build index

https://docs.unity3d.com/ScriptReference/SceneManagement.SceneManager.GetActiveScene.html
https://docs.unity3d.com/ScriptReference/SceneManagement.Scene-buildIndex.html

[robust yacht]

ah so i need to use getactivescene?

thank u for the documentation

So i can do
if(scenemanager.getactivescene() = 0

then move players position

public class ScenePlayerLoad : MonoBehaviour
{ 
        [SerializeField] private Transform player; 
        private Vector3 targetPosition;

    private void Update()
    {
        if (SceneManager.GetActiveScene() == SceneManager.GetSceneByName("Boss Fight"))
        {
            player.position = targetPosition;
        }
    }
}

I tried this

[hallow heron]

target position isn’t assigned unless you want it to be 0,0,0

@robust yacht

[robust yacht]

ah

So do i need to give it values in the start function

[hallow heron]

You could

[robust yacht]

okey

[robust yacht]

i gave the vector values in start but it didnt spawn my player there

    private void Start()
    {
        targetPosition = new Vector3(-91.59f, -1.20f, 0.0f);

[hallow heron]

I’ve never used the scene load += and -= before so I don’t really know what they do

[robust yacht]

well i decided to ditch them and do it when scene loads

lol

[hallow heron]

How are you changing scenes?

[robust yacht]

scenemanager.loadscene("string")

[hallow heron]

Ok so is there a player on every scene or are you moving it across

[robust yacht]

Moving it across

with a dontdestroy

[hallow heron]

hmm ok

[hallow heron]

You don’t get a null reference exception right?

[robust yacht]

no

[hallow heron]

^ and this scene is also moving across?

[robust yacht]

well i dont think that specific code was working

since my other script already did that

and it didnt move me

[hallow heron]

try

      if (SceneManager.GetActiveScene().buildIndex == 0)
        {
            player.position = targetPosition;
        }

replace 0 with the build index of the boss fight

[robust yacht]

and should i put this on a script in update that has the dont destroy script on

[hallow heron]

I think so

I just realized it will freeze the player

[robust yacht]

how come?

is it because theres a delay

[hallow heron]

if the scene is the bossfight, it constantly resets the player's position

[robust yacht]

well i dont even think it will work but i will try

considering our luck

huzza it worked

but yea it freezez me

[hallow heron]

is this the only scene where the position matters or are there other ones?

[robust yacht]

erm no

theres only two scenes in terms of player movement and not ui

by default the player spawns in the correct position on the first level

but in the boss fight is the one im trying to fix

so it wont matter if its changed for the player for that specific part of the game

if thats what u mean

I mean i can make a bool and make the if statement a function on its own

actually that wouldnt work 😂

[hallow heron]

private Vector3 targetPosition
    void Awake()
    {
        SceneManager.sceneLoaded += OnSceneLoaded;
    }

    void OnSceneLoaded(Scene scene, LoadSceneMode mode)
    {
       if(scene.buildIndex == 0)
        {
          player.position = targetPosition;
        }
    }

@robust yacht found something online that i modified

[robust yacht]

nevermind im special

[robust yacht]

oooo

ok

[hallow heron]

wait the game is just 2 scenes?

@robust yacht

[robust yacht]

Yeah its for a game jam

[hallow heron]

oh nvm go back to what you had

[robust yacht]

nothing massive

[hallow heron]

that froze

[robust yacht]

oh ok

how do we fix that then

well i have 3 scenes total

1 menu 2 levels

[hallow heron]

      if (SceneManager.GetActiveScene().buildIndex == 0)
        {
            player.position = targetPosition;
            this.enabled = false;
        }

either we destroy or disable the script

[robust yacht]

ah i see what ur doing

yea ill try that

Awesome it works, thanks a lot pumpkin, massive legend

[hallow heron]

good luck on the game jam!

[robust yacht]

❤️

@hallow heron if your still online i would love to know if it is possible to make it to where you can only have one buff showing in text, so if i pick up two speed crystals, the text still only has one speed

[hallow heron]

Sorry, I was gone for awhile, hopefully it’s not too late. You’ll want to only AppendLine if the list doesn’t contain the string.

void UpdateText()
{
     if(list.Contains(“Speed”) == false)
     {
       AppendLine 
     }
     else
     {
       // list already contains speed
     }
}```
