❔ ✅ get unknown range of list to display?

internal record Evidence(string Name)
{
    public static Evidence None = new Evidence("None");
    public static Evidence Emf5 = new Evidence("EMF 5");
    public static Evidence SpiritBox = new Evidence("Spirit Box");
    public static Evidence Writing = new Evidence("Ghost Writing");
    public static Evidence Dots = new Evidence("DOTs Projector");
    public static Evidence Ultraviolet = new Evidence("Ultraviolet");
    public static Evidence Freezing = new Evidence("Freezing Temperatures");
    public static Evidence GhostOrbs = new Evidence("Ghost Orbs");

    public override string ToString() => Name;
}

internal record Evidence(string Name)
{
    public static Evidence None = new Evidence("None");
    public static Evidence Emf5 = new Evidence("EMF 5");
    public static Evidence SpiritBox = new Evidence("Spirit Box");
    public static Evidence Writing = new Evidence("Ghost Writing");
    public static Evidence Dots = new Evidence("DOTs Projector");
    public static Evidence Ultraviolet = new Evidence("Ultraviolet");
    public static Evidence Freezing = new Evidence("Freezing Temperatures");
    public static Evidence GhostOrbs = new Evidence("Ghost Orbs");

    public override string ToString() => Name;
}

this information is generated into a string like string evidence = "EMF 5, Spirit Box, Ghost Writing";. Knowing that it's not the same evidence every time, how can I cut off the last piece of evidence and display the first two?

split the string on , and drop the last item?

Mekasu0124•10mo ago

string evidenceZero = string.Join(", ", (IEnumerable<Evidence>)ghost.Evidence).Split(", ")[0];
string evidenceOne = string.Join(", ", (IEnumerable<Evidence>)ghost.Evidence).Split(", ")[1];
string evidnce = evidenceZero + evidenceOne;

string evidenceZero = string.Join(", ", (IEnumerable<Evidence>)ghost.Evidence).Split(", ")[0];
string evidenceOne = string.Join(", ", (IEnumerable<Evidence>)ghost.Evidence).Split(", ")[1];
string evidnce = evidenceZero + evidenceOne;

like this?

Pobiega•10mo ago

ugh, no

Mekasu0124•10mo ago

well this is how it's generated into a string....

Pobiega•10mo ago

well if you already have it as an array, isnt it better to just use the array then? why convert to string, remove the last item, then convert back into array, to then convert to string again? that seems insanely convoluted 😄

Mekasu0124•10mo ago

idk that's why I asked. This isn't python so it's confusing.....sorry. I don't mean to disappoint

Pobiega•10mo ago

so, this is an X Y problem you're trying to solve X, your attempted solution is Y, so you're asking about Y I need you to tell me about X what is the actual problem you are trying to solve here?

Mekasu0124•10mo ago

ok you said it's already an array

Pobiega•10mo ago

ghost.Evidence is, last time we talked so if you have access to that, its much easier to work with that directly

Mekasu0124•10mo ago

string evidenceZero = string.Join(", ", (IEnumerable<Evidence>)ghost.Evidence[0]);
string evidenceOne = string.Join(", ", (IEnumerable<Evidence>)ghost.Evidence[1]);
string evidence = evidenceZero + evidenceOne;

string evidenceZero = string.Join(", ", (IEnumerable<Evidence>)ghost.Evidence[0]);
string evidenceOne = string.Join(", ", (IEnumerable<Evidence>)ghost.Evidence[1]);
string evidence = evidenceZero + evidenceOne;

so I should be able to do something like this then, right?

Pobiega•10mo ago

rather than the string version uhm.. what do you think string.Join does?

Mekasu0124•10mo ago

joins an array to a string that's why I'm trying to index the array

Pobiega•10mo ago

right. and ghost.Evidence is an array, that we agree on what is ghost.Evidence[0] thou? is that also an array?

Mekasu0124•10mo ago

internal class Ghost
{
    public required string Name { get; init; }
    public required string NormalizedName { get; set; }
    public required string Description { get; set; }
    public required string Weakness { get; set; }
    public required string Strength { get; set; }
    public required Evidence[] Evidence { get; set; }
    public required HuntSanity Sanity { get; set; }
    public required Speed Speed { get; set; }
    public required Tell[] Tells { get; set; }
    public required Behavior[] Behaviors { get; set; }
    public required HuntSanityBehavior[] HuntSanityBehaviors { get; set; }
    public required HuntSpeedBehavior[] HuntSpeedBehaviors { get; set; }
    public required Evidence[] GuaranteedEvidence { get; set; }
}

internal class Ghost
{
    public required string Name { get; init; }
    public required string NormalizedName { get; set; }
    public required string Description { get; set; }
    public required string Weakness { get; set; }
    public required string Strength { get; set; }
    public required Evidence[] Evidence { get; set; }
    public required HuntSanity Sanity { get; set; }
    public required Speed Speed { get; set; }
    public required Tell[] Tells { get; set; }
    public required Behavior[] Behaviors { get; set; }
    public required HuntSanityBehavior[] HuntSanityBehaviors { get; set; }
    public required HuntSpeedBehavior[] HuntSpeedBehaviors { get; set; }
    public required Evidence[] GuaranteedEvidence { get; set; }
}

in the ghost model, it is done as an array.

"Evidence": [
  {
    "Name": "EMF 5"
  },
  {
    "Name": "Spirit Box"
  },
  {
    "Name": "Ghost Writing"
  }
],

"Evidence": [
  {
    "Name": "EMF 5"
  },
  {
    "Name": "Spirit Box"
  },
  {
    "Name": "Ghost Writing"
  }
],

then it's stored to the json file like so. When I pull it from the json file,

string evidenceZero = string.Join(", ", (IEnumerable<Evidence>)ghost.Evidence))

string evidenceZero = string.Join(", ", (IEnumerable<Evidence>)ghost.Evidence))

I do so like this to get it into a string that looks like "EMF 5, Spirit Box, Ghost Writing" so it's easier to print to the screen. I'm just trying to figure out how to drop the last item in the string

Pobiega•10mo ago

but why in the string? isnt the string literally just a display interpretation of the array? you shouldn't be modifying the string, you should be modifying the array and honestly, at that point, it shouldn't be an array, it should be a list you're still focused on Y tell me about X. why do you want to drop the last item from the string?

Mekasu0124•10mo ago

because it's part of the game?

Pobiega•10mo ago

explain

Mekasu0124•10mo ago

for what? It's part of the game. I just need to know the most efficient way to drop the last item from that string, or from the array.....

Pobiega•10mo ago

What i've gathered about your project so far is that its a guessing game right you get some info on a ghost and you're supposed to identify it

SinFluxx•10mo ago

I'm assuming Phasmophobia or similar? You go around the map and discover certain pieces of evidence then mark them in your notebook as discovered evidence to identify what type of ghost it is

Mekasu0124•10mo ago

it's just part of the games difficulty level.

Pobiega•10mo ago

there we go THATS what X is

Mekasu0124•10mo ago

I don't understand why the reason I'm wanting to drop the last item in the list is relevant to learning how to do it

Pobiega•10mo ago

you want a way to "hide" evidence from the player to increase difficulty

Mekasu0124•10mo ago

it's just dropping one item from teh list

Pobiega•10mo ago

Look, I either help you my way, or I don't help you. Pick one.

Mekasu0124•10mo ago

me not wanting to release details about my game that I'm developing that I haven't told anyone about at all has nothing to do with receiving assistance in learning how to drop an item from a list. But alright, your pride. your way. thanks for the help
