[zealous oxide]

yup, i believe so! i've got my platform effector2d collider mask set to "everything"

[slender nymph]

okay and is the enemy object's collider a trigger collider?

[zealous oxide]

the enemies have thier own layer called "enemy"

[zealous oxide]

the enemy itself is, yeah but not the "groundCheck" child object

[slender nymph]

and what layer is the groundCheck object on?

[zealous oxide]

groundCheck is also on "enemy"

platforms are on "platform"

[slender nymph]

and those layers can collide in the Physics2D settings?

[zealous oxide]

I thought it would have, how would I check? its falling through the platforms so possibly not? it's got a dynamic rigidbody 2d

[slender nymph]

in the Physics2D settings

[zealous oxide]

everythings on by default

[slender nymph]

then there's some information that you aren't providing 🤷‍♂️
your mail slot screenshots where we only see very specific info aren't really providing all of the necessary context

[zealous oxide]

i'm happy to share more, just not sure what else I can share?

[slender nymph]

show the entire setup. full inspector/hierarchy

[zealous oxide]

ok i've figured it out, the Box Collider 2D, has the "is trigger" ticked. when i untick it, it doesnt fall through

but i'd like to use that box collider as a trigger for combat actions, eg when the player character melee attacks the enemy

[slender nymph]

well by the sound of it, your ground check collider isn't actually a child of the rigidbody2d

which is why i wanted to see more of the setup

[zealous oxide]

I can send you a full screenshot if thats what you're after?

[swift crag]

yes, that's what boxfriend is after.

[zealous oxide]

❤️

[slender nymph]

and the GroundCheck object

[swift crag]

A trigger collider overlapping a non-trigger collider can produce trigger messages.

[zealous oxide]

enemy only has a single, box collider 2d on it though?

[slender nymph]

it doesn't have a collider. so it's no wonder it isn't acting as a solid collider for collisions. the way you described it before you made it seem like it had a non-trigger collider

[zealous oxide]

so the ground check needs its own box collider?

[slender nymph]

if you intend for that to be how it collides with the ground, yes. otherwise you need to make the enemy's collider not a trigger

[swift crag]

currently, the GroundCheck game object does absolutely nothing

[slender nymph]

the rigidbody needs at least one non-trigger collider in order to be able to actually collide with stuff

[zealous oxide]

I see. on my player character the box collider has no "is trigger" and the respective players "groundcheck" is also empty, as it was for the enemy

[slender nymph]

right so that player's own collider is the non-trigger collider used for collisions

[zealous oxide]

ok brilliant, thank you, thats fixed the problem. I thought I was being dense

[pine edge]

the thing is, I'm not sure what to use here. if I do col.Lerp(x,y, currentHeat), it won't lerp in relation to the current float/heat value. i.e if the max value of heat can be 10, then at 5 it should be a colour between white and red.

[slender nymph]

currentHeat / maxHeat

and make sure at least one or both are floats

[primal tree]

I'm coming back to a Unity 2D Platformer project I had to stop working on in May. When I left it, I had some very annoying trouble dropping down through platforms with the character. I'm still having those problems, and I can't work out what's going on with it. Can anybody help? I'm happy to send you the entire project, if that would be best. https://forum.unity.com/threads/why-is-my-2d-character-getting-pushed-down-0-544207-in-y-when-uncrouching-below-a-passable-platform.1439920/

[neat tulip]

Could i have help with something to do with 2d movement

please

[slender nymph]

https://dontasktoask.com/

[neat tulip]

Huh

[slender nymph]

read it

[slender nymph]

holy cow the formatting in that code is something else. but it seems like the issue is just that the rigidbody is depenetrating from the colliders it overlaps when it "stands up". which is kind of expected behavior with rigidbodies

[neat tulip]

I for some reason am able to double jump infinitly

and don't dont how to fix it

looked it up andf everything

[primal tree]

Yeah, that's somewhat aligned with what I was thinking, but I'm really not sure where to go from here. I spent forever trying to solve the issue in May, and I'm still confused now. =/ Rrrgh.

[slender nymph]

you're not doing any sort of ground checking and you aren't even moving in a physics friendly way either

Righto. I'm self-taught, so I'll take whatever advice you can give.

As I say, I'm happy to provide the project to anyone who can help. I'm reasonably experienced, I thought, but this has confuzzled me almost totally.

[ashen ferry]

try to watch a vid https://www.youtube.com/watch?v=CFRhGnuXG-4 on how to solve all that nesting bro u gonna spend way too much time on any bugs with that

[primal tree]

@ashen ferry Who are you referring to here?

Nice emoji! =D

[ashen ferry]

lmao accident

[primal tree]

What's the nesting you have an issue with? The deepest if level I have is 4. I'll take a look at the video, but I'm unsure how else I'd handle this specific situation.

[final trellis]

getting a strange math issue, not sure of the right term but im making an equation to "cyclically clamp" a number between 0 and 2, where once it gets past 2, instead of clamping to 2, it 'cycles' back to 0, and when it goes to -1, it cycles back to 2, my equation ends up being num % 3, which does exactly as described on a calculator, however it seems to calculate -1 % 3 as -1 instead of 2

[primal tree]

Can anybody help me track down my issue with dropping down through the 'thin' floors?

[primal tree]

So, I've watched this video, and I'm aligned with most of the values expressed within. I'm doing a 4-if nest for a specific, considered purpose, so that's in line with those guidelines.

[ashen ferry]

ill refactor one method of urs into what I mean

[primal tree]

That's kind of you, I appreciate it.

[sour wren]

Ayoo guys!! I wanna make my own realistic arcade car system in Unity, but I have a question, do I need to rig the car to make the car?

Im beginner on Unity

[primal tree]

You'll need to rig it, but mostly within Unity. There's probably a good simple car tutorial in Unity - I'll have a look...

[sour wren]

In Unity? I thought I had to do the rig in Blender, I saw this in a car tutorial when I was trying to do it in Unreal

[eternal needle]

you can just add 3 if the result is negative after the % operator, in c# its a remainder operator not mod so its not guaranteed to be posiitve

[primal tree]

Yikes. One sec!

https://learn.unity.com/project/karting-template

Crikey, why didn't that URL work first time? Anyhow. Yeah, you'll do most of your rigging in Blender, then trigger those animations in Unity. However, in getting the car moving, you'll want to setup wheel colliders etc. in Unity - and it may be easier to setup wheel turning etc. in Unity.

But load up the Unity Learn project and poke around with how the car is setup - that's a good starting point.

Again, if anybody can help fix the platforming in my project, I'd be very appreciative!

[ashen ferry]

https://hatebin.com/eqbcoywibq couldnt get that much juice out of it tbh but im sure someone can improve it further I split ur methods into 3 according to velocity with self explaining names u dont need comments for them now, way nicer to collapse whole method as well got rid of few else with guard clauses etc and if you keep adding functionality u wont end up with gigachad super method

[hidden citrus]

how do you go about adding a custom extension/button to a pre-existing tool like transform? I want to create a "reset position/rotation/scale" type button using custom code

[short hazel]

This option is already available from the menu top-right

[wintry quarry]

Write a custom inspector for the Transform type

But yes, it is

[primal tree]

I appreciate your efforts, but as you say, not much more juice there. I think I'll focus on trying to solve my platforming issues before going back and cleaning up my code.

I think if you looked at my project, you'd approve of at least 90% of what I have there. Cheers, though!

[hidden citrus]

what is the default transform api? looks like its exposed now but i dont want it to look like that. im just trying to tack on a custom button

[tender stag]

when im holding an ak for example, and i switch to another slot with an ak, it doesnt switch to the other one
https://hastebin.skyra.pw/binefajevi.csharp

its line 83 im pretty sure
else if(currentItem != itemsDictionary[selectedCell.item.itemData])

[tender stag]

u can see when i equip the first ak which only has 10 ammo, and then straight away switch to an ak with 30 ammo

the Switch method doesnt get called

this works

[rancid tinsel]

i have an array that goes from 0 to 19 and im using this to pull from it and got an out of index error, did i miss something cuz im feeling kinda sick and i might just be making basic mistakes

here is the full code https://gdl.space/ugaxawovuk.cpp

[polar acorn]

If you want to roll a random index in a collection, use that collections size instead of a hard coded outer bound

[rancid tinsel]

would 0, 20 not achieve the same result?

[polar acorn]

That is why int randoms are max exclusive, solely so you can plug the length directly into that second parameter

[hidden citrus]

Er, better yet, how can I get "this.transform" from the editor extension?

   if (GUILayout.Button("Reset All"))
        {
//// stuff here 
        }

unsure on how to access transform/rotation/scale

[polar acorn]

Only if your list has exactly 20 things in it

[rancid tinsel]

it does (its for a d20 dice)

so numbers from 1 to 20

[proud nexus]

can someone help me, i have a sprite for a wood plank (2d game), and i want to resize it to be the floor of my game, however i dont want to stretch it out, i want to repeat it until its the correct size, the first image is the one that i want to change to be repeated to make it look like the second image

[polar acorn]

Are you sure

How have you checked

[rancid tinsel]

yes

oh whoops it pasted twice

[polar acorn]

Okay that shows that you have at least one list with 20 things in it, but nothing shows that this is the list you're getting the error on

[rancid tinsel]

its the only list, the error was for line 49 from the code i sent

[polar acorn]

Have you tried logging the length of the list before you access it

[rancid tinsel]

so this

[proud nexus]

plrease help 🥺

[rancid tinsel]

how would i go about doing that?

[polar acorn]

Log the length of the array the line before the error

[rancid tinsel]

im pasting like an idiot, the line within the ChangeSprite()

[rancid tinsel]

wouldn't the length of the array be 100% 20 if its public in the script and 20 in the inspector tho?

[polar acorn]

Stop guessing and log it

[rancid tinsel]

there is a chance that the roll++; line might somehow be messing with it

[rancid tinsel]

idk how to log it

[polar acorn]

Debug log should literally have been the first line of code you ever wrote in unity

[rancid tinsel]

i know how to do Debug.Log but idk how to apply it the way you want me to

[ashen ferry]

Debug.Log(arr.Length); shh dont tell I told

[polar acorn]

Log the length of the array

Put the length inside the log

[rancid tinsel]

diceArray.Length?

it returned 20

[polar acorn]

https://learn.microsoft.com/en-us/dotnet/api/system.array.length?view=net-7.0

[primal tree]

Don't suppose you have any ideas based on this? I meant to follow your point up earlier, but I got a little side-tracked.

[polar acorn]

Okay, now try logging roll as well

[rancid tinsel]

roll already getting logged, it is 1 lower than the number on the dice (since the 1 dice is 0 in the array) so i did roll++ after the array code

but there is a chance i missed something where it goes out of index after a few tries

[polar acorn]

So, log roll before you use it

before the error

roll is greater than the length of the list, which is your error

the list's length seems correct

so now check what roll is when it errors

[rancid tinsel]

guessing i change the random range to like 18, 20 so i can actually test for the error

since the error seems to happen when you roll above the index

otherwise id be here all day

also i got this and i forgot how to turn it off

whats the keybind again?

[ashen ferry]

insert

[rancid tinsel]

thank you

yeah idk the error doesn't seem to happen

even after rolling 2 20s in a row

[ashen ferry]

code got scared of debugging

[rancid tinsel]

ahh i recreated it

seems to happen when i spam click the dice

so its something to do with the coroutines prob

[polar acorn]

So, is that logging the value of roll inside of the function throwing the error?

[rancid tinsel]

i dont deactivate the dice

[polar acorn]

If so, then a value of 20 is too high

[rancid tinsel]

so the roll++ keeps going off

before it can reset

i think

[polar acorn]

The list has 20 elements in it, meaning 19 is the highest value

[rancid tinsel]

yeah but Random.Range is maxExclusive no?

[polar acorn]

Yes but you aren't using the result of the range are you, you're adding one to it

[rancid tinsel]

ohhh i get what youre saying now

i mean normally i use the result of the roll and then after it was used i add 1 to it

but i think i forgot to disable the dice after it starts rolling

therefore if you spam it, it keeps doing roll++

[primal tree]

Sorry to repeat this issue, but I really am bamboozled by it...

please configure it using the link below:

the docs should contain everything basic right? like movement and hitboxes?

[frosty hound]

The docs contain information for all aspects of Unity. It doesn't cover how to make a game.

[lone mist]

ah

[swift crag]

they do cover things you can use for movement (rigidbody, character controller) and hitboxes (rigidbody again, colliders)

[ashen ferry]

maybe someone knows whats up with this I cant rename classes it goes right back to what it was

actually tested with 2 random other classes just in case im being oblivious about something again and got one to rename but changing it back is yet again impossible lol

[alpine flare]

I think thats because it connects to what you named the script in unity

maybe changing it in unity first

[ashen ferry]

yea that solved thanks now that I look at the class which renamed itself the way I tried its name changed in editor as well

no consistency?!

[neat tulip]

oh ok

my bad

[unique violet]

how can I get all the children of a gameobject as a list?

[swift crag]

You can iterate over a Transform's children

foreach (Transform child in someTransform)

it's a little awkward because it's not an IEnumerable<Transform> -- just IEnumerable -- so I don't think you could easily do

new List<Transform>(someTransform);

[unique violet]

ah okay thank you

[swift crag]

hence why you can't do foreach (var child in someTransform)

you'll just get objects

(which you could cast to Transform, sure, but it's annoying)

smells like very very old engine code :p

[iron lava]

So im trying to learn Unity for the first time (I know what a time to start) and I've started with a kind of flappy bird clone, but right now I have a trigger to increase my score when I go through the pipes but I gave my Player entity two Box Colliders so the trigger is going off twice, what would be the best way to fix this and avoid it in the future?

[swift crag]

I would add a component to the game object with the score collider on it

[ashen ferry]

can I assume all awakes on prefab are already ran just below instantiate line or it happens sometime later

[swift crag]

That component would have a bool. It would be set to true when you hit the zone

[swift crag]

Every Awake message will be sent before the Instantiate call returns

[ashen ferry]

nice ty

[swift crag]

so, maybe, in the OnTriggerEnter method on your ship:

void OnTriggerEnter2D(Collider other) {
  var zone = other.GetComponent<ScoreZone>();

  if (zone && !zone.hit)
  {
    zone.hit = true;
    // add a point
  }
}

where ScoreZone is a really tiny monobehaviour

public class ScoreZone : MonoBehaviour {
  public bool hit = false;
}

If the score code is on the pipes, not the player, it'd be even simpler

you'd just add that "hit" field to the component that gives you a point

and only give a point if it hasn't been set to true yet

[iron lava]

@swift crag I have the trigger in the prefab with the "pipe" colliders. My problem is it registers both of my players colliders but I only want it to register them as one

[swift crag]

Okay, so "Middle Script" is what gives you a point?

[iron lava]

yeah

[swift crag]

add a bool field to that component, so that it can remember if it has touched the player yet

when you give the player a point, set it to true (and skip the points entirely if it's already been set)

[swift crag]

(by "field" I mean a variable that is in the definition of the class, like this, in case you haven't seen that term yet)

logic in your "Middle Script" component is a field

[iron lava]

like this?

[swift crag]

Yep.

So, right now, you unconditionally run Logic.addScore() in the trigger enter method

You want to make it so that you only do that if hit is false

[solid timber]

Hey, I have two 3d objects (flattened cubes) that are on the same Layer (SliceLayer), and I have changed the Physics so they cannot collide with each other in the Project settings.

So now I can lay these two 3d objects ontop of each other in the game, but there is a Z layer fighting going on. Is there a way to have 2 3d objects ontop/inside each other and then still show one instead of having Z fight?

[swift crag]

simplest thing to do is to give one a tiny position offset

I think you could also write a custom shader that adds a bit of offset

https://docs.unity3d.com/Manual/SL-Offset.html

...but that sounds like a pain in the ass

[iron lava]

sorry im very new to this how would you type that out? if hit = false Logic.addScore(); or something?

[swift crag]

Have you written any if statements yet?

oh, I missed the "if" in there

yeah, that's the idea

if (!hit) {
  // do stuff 
}

you can just use ! to negate it

instead of doing if (hit == false)

[iron lava]

so like that then?

[swift crag]

Close, but you're missing something to set hit to be true afterwards

otherwise, hit is going to stay false every time you enter the trigger collider

You could put that in the if statement, or just do it separately. same outcome.

(just don't do it before the if statement, of course, or it'll never succeed)

[high garnet]

Anyone know of any good ways to graph a animation curve in UI? I just need to copy it over into a UI form to act like a car dyno sheet

[swift crag]

hm, not sure how I'd draw a nice smooth curve

the first thing that came to mind was to just sample a bunch of points and draw dots on a texture

[high garnet]

Yea, I watched the code monkey line graph thing and just figured I’d spam points from the curve with a for loop lol

[swift crag]

i think that's how a TI-84 does it

[sly bolt]

any help?

[iron lava]

sorry again but how do you change the false to true? Ive never really done if statements before

[swift crag]

this has nothing to do with the if statement

just set hit = true;

[iron lava]

right under the if statement?

[swift crag]

That will work.

This will:

• If hit is false, call Logic.addScore();
• Set hit to true

you could also do

if (!hit) {
  Logic.addScore();
  hit = true;
}

This will behave the same (it just avoids setting hit to true more than once)

Doesn't matter at all.

[iron lava]

okay thank you I think I understand how that works logically

[hidden citrus]

hey, what's a good way to set the collider to the raycasts hit distance?

I want the box collider to rescale itself from the rays root, out to the current hit point. though it seems like the debugger ray isnt stopping on contact with objects

   IEnumerator LaserStream()
    {
        while (isSpinning)
        {
            Ray rayLaser = new Ray(offset.position, transform.forward * rayDist);
            if (Physics.Raycast(rayLaser, out hit, rayDist, layerMask))
            {
            }

            colliderZ = rayDist;

            colliderVolume.size = new Vector3(colliderX, colliderY, colliderZ);
            colliderVolume.center = new Vector3(0, offset.position.y, rayDist / 2);

            Debug.DrawRay(offset.position, transform.forward * rayDist, Color.blue);

            yield return new WaitForSeconds(.15f);
        }
    }

[swift crag]

DrawRay just draws a line

[hidden citrus]

in my current example, itll draw it out based on the ray, but the ray itself isnt resizing on contact. does debug ray resize automaticaly?

[swift crag]

it doesn't do any physics

[hidden citrus]

is there a way to make the box resize on hit? Like say the laser hits a rock in front of the player, the collider should stop at that point, not pass through

[iron lava]

when I do it like that I get a red ~ why does it do that/ do I need to worry about that?

[swift crag]

Yes, that is an error.

Notice that you added an opening {, but have no corresponding closing }

This will cause an error as soon as the lexer (which chops your source code up into pieces the compiler can understand) finds something that doesn't make sense

[hidden citrus]

like have the ray stop here, then pass that info the collider and divide it by 2 for the center

[swift crag]

Where that actually is can vary.

this really confuses the compiler

notice how the error squiggles show up...earlier

in this case, it's because the missing } makes everything part of the What function

and then, at the very end, we get an error because we hit the end of the file without closing all of the curly braces

hence...

[iron lava]

oh okay I had to add one } for the void trigger and then another for the public bool. I see how that works

that works wonderflully thank you so much

[swift crag]

Right. Every opening { must be balanced by a closing }

The outer pair opens and closes the class definition. The inner pair opens and closes the method definiton.

And then the innermost pair is just a "block statement"

{
  statement1
  statement2
  statement3
}

[hidden citrus]

my math isn't too great but something to do with hit distance. trying to figure out "From origin, to hit distance". I imagine the offset -> hit distance = the length of the ray

      Ray rayLaser = new Ray(offset.position, transform.forward * rayDist);
            if (Physics.Raycast(rayLaser, out hit, rayDist, layerMask))
            {
            }

            var hitDist = hit.distance - offset.position.x;

            colliderVolume.size = new Vector3(colliderX, colliderY, hitDist);
            colliderVolume.center = new Vector3(0, offset.position.y, hitDist / 2);

            Debug.DrawRay(offset.position, transform.forward * rayDist, Color.blue);

            yield return new WaitForSeconds(.15f);
        }

[solid timber]

Thanks, will look into it!

[swift crag]

note that messing with sorting priority won't help -- that just changes the order that materials are rendering in

one already renders before the other; it's the z-fighting that's the problem

One option IS to make both materials Transparent, rather than Opaque.

[unique violet]

how can I get the text data of a txt file hosted on github

[swift crag]

Whichever one gets drawn second will completely clobber the first one

[swift crag]

getting some XY Problem vibes here

what are you trying to do

[swift crag]

Transparent shaders don't affect the depth buffer, so you can't possible get Z-fighting

[unique violet]

well im trying to make a ui list that has content based off the github text. if that makes sense

[swift crag]

for a message-of-the-day, or something similar?

something that you have to go on the internet to retrieve every time you use it

[hidden citrus]

aye figured it out i believe. unless ya'll got a better suggestion for "resize box collider to raycast length"

    IEnumerator LaserStream()
    {
        while (isSpinning)
        {
            Ray rayLaser = new Ray(offset.position, transform.forward * rayDist);
            Physics.Raycast(rayLaser, out hit, rayDist, layerMask);
            var hitDist = hit.distance;

            if (hit.distance <= 0)
                hitDist = rayDist;

            colliderVolume.size = new Vector3(colliderX, colliderY, hitDist);
            colliderVolume.center = new Vector3(0, offset.position.y, hitDist / 2);

            Debug.DrawRay(offset.position, transform.forward * rayDist, Color.blue);

            yield return null;
        }
    }

[unique violet]

i also want to split them by each 5 lines so I can each piece of data per shortcut

@swift crag any updates?

[swift crag]

you can use https://docs.unity3d.com/Manual/UnityWebRequest.html to fetch data

i would suggest just storing your data as JSON and then using something like Json.NET to deserialize it

[unique violet]

alright thanks

[rancid tinsel]

how would i carry over variables between scenes?

i have a game manager in one scene (where you choose your stats) and a game manager with the same script attached in the next scene where I would want to keep storing those stats so that I can use them within the actual game

[eternal needle]

you can put it in DontDestroyOnLoad (DDOL)

the object that has the script

[rancid tinsel]

how would i do that?

[summer stump]

DontDestroyOnLoad(gameObject);

https://docs.unity3d.com/ScriptReference/Object.DontDestroyOnLoad.html

[lone mist]

why is this guy not showing up

[rancid tinsel]

so like this on the script?

[summer stump]

Are you instantiating it? Show the code
If it's supposed to be in the scene, show its inspector

[summer stump]

Don't need this, but yes

[rancid tinsel]

i was actually going to ask what "this" is for cuz i know gameObject refers to the object thats holding the script right?

[summer stump]

Refers to the instance of the script, and yes

[rancid tinsel]

i see, thank you 🙂

[rancid tinsel]

ah and now that i did this will i be able to call onto that original game manager, so i dont need a second one in the next scene right?

[lone mist]

why is my little guy not showing up 😭 can anyone help me?

[glad comet]

Sorry if this is a simple fix but my code for my character to jump up with the spacebar won't work. What is the problem?

[civic coral]

is coding the same for a vr project and a 3D project

[summer stump]

So it is supposed to exist in the scene before play starts?

[lone mist]

i havent coded anything im just setting things up

[summer stump]

Set the z to 0

[lone mist]

there it goes

thamk you

wait

isnt z a 3d thing

[summer stump]

2d in unity is 3d still. Z is just used more like "distance from camera" in unity 2d

[sour wren]

Guys, how can I rig a car? I intend to create my own car system, would it be possible for me to invent my own car rig?

[civic coral]

is there a system in unity for missions for your game

like kill [bad guy] and steal [key] to open [the big bad mafia room]

[summer stump]

Possible, yes. How to do it, i dunno

[summer stump]

Not afaik. It's entirely up to you to create. May be an asset for that though.

[sour wren]

Perfect, ty!!

[summer stump]

I see this:
https://assetstore.unity.com/packages/templates/systems/mission-system-135406

Edit: hmmm, don't think that's what you're looking for actually

[civic coral]

if I buy this can you explain how this will work dose it like teach me how to add missions or will add a system for me?

[summer stump]

Usually assets have instructions. I dunno how it works or how to implement it

And it looks real weak.

Here is perhaps a better one:
https://assetstore.unity.com/packages/tools/game-toolkits/quick-simple-missions-75462

But generally, these assets are still just a framework, you will need to implement them and tie them in with the rest of your game. Gonna have to write some code somewhere, and it won't add the system for you

[tropic crown]

I've been following a yt video on a working survival system for a hunger system but I cant get the food eating function to work... Please help

[summer stump]

For one, it looks like your !ide isn't configured

Also, can you show the SurvivalHunger script?

Last, what are _hungerToReplenish and _thirstToReplenish set to?

I would put some Debug.Log calls into the OnTriggerEnter too, to see if it's getting past the if conditions

[vague sage]

Hello I'm a super beginners

[vague sage]

and im wondering why my script isnt working when i folllowed the the tutorial to a tea.

Did i do something wrong in my unity

[vague sage]

Or did I do something wrong in my visual studio

[tropic crown]

How do I do that? I'm very new still..

[summer stump]

Is there a reason you are in debug mode?

[summer stump]

Look at the docs for it, there are good examples
https://docs.unity3d.com/ScriptReference/Debug.Log.html

[tropic crown]

just wanted to see if could clue me into why its not working

[teal viper]

You'll need to provide more details, if you need help. Start from explaining what you mean by "not working".

[vague sage]

but i dont see the error

i thought it would show at the bottom

[lone mist]

help, the tutorial im following for sprites shows the lines of code colored but mine dont, what am i doing wrong?

[vague sage]

where can I detect the error>?

[summer stump]

!ide @vague sage , look at the bot too

[vague sage]

okay

hold up.

[teal viper]

Open the console tab. That's where the errors should be.

[lone mist]

thank you it solved it 🙏

[vague sage]

this?

oh

wait one second

[summer stump]

Are you using vs code? Because that is for vs code. But yes that would be it

[vague sage]

I am

also your thing didnt work

or i cant see Preferences when I open edit

[summer stump]

What did you do exactly. You got that extension, and what else

[vague sage]

i dont have the extension

should i get it?

[summer stump]

Did you... read the bot? Yes of course you need it

[vague sage]

okay im installing

what shuld I expect now?

to be able to run da code?

[summer stump]

Preferences you want is in UNITY not vs code

[summer stump]

To see the errors in the ide

[vague sage]

okay sound good tysm

ill be back if thats fine

[tropic crown]

this makes no sense to me

[rancid tinsel]

im struggling with figuring out how to grab values from a script thats DDOL'd but in a different scene as it isnt letting me assign it in inspector

could someone help me out please

[vague sage]

VehicleController

[summer stump]

You write Debug.Log("found player"); after the first check or something

[summer stump]

What doesn't make sense?

[vague sage]

@summer stump

[tropic crown]

ok the collider is working It says found player when I walk into the sphere collider

[summer stump]

Ok, do something similar with the next check

[vague sage]

@summer stump

can i start coding ?

[tropic crown]

Ok so It didn't show up when I moved it here

[summer stump]

That dotnet error worries me. The unity extension should have installed any dependencies you needed..
But yeah you can code whenever. Do you have any compiler errors?

[vague sage]

not at the moemnt.

[summer stump]

Does the player HAVE the SurvivalManager attached?

[summer stump]

Ok perfect!

[vague sage]

game runs

[tropic crown]

yeah

[vague sage]

time to put the cod ein and see if it will finally move

[tropic crown]

It could be that my refrence is my PlayerCam and no the PlayerObj

[summer stump]

Where did you put the debug the first time? It passed the tag check, right?

[tropic crown]

yeah

and the second line

I feel like the player input should be the player object not the playercam

but it wont let me put any other item in the slot

[summer stump]

Ok... try doing this:

Replace the getcomponent line and null check with this line:

if (!other.gameObject.TryGetComponent(out SurvivalManager survivalManager)) return;

The reference thing shouldn't affect this at all

Dunno if you even need to go through gameObject actually

[tropic crown]

nothing seemed to happen

no debug log still

[summer stump]

Ok, that was just a check. I thought there was something weird with is null but I can't remember what exactly

[summer stump]

Wait.. THIS
#💻┃code-beginner message
Object has a collider, right?

[tropic crown]

what?

the playerObj has a collider @summer stump

[lone mist]

ok so im following a tutorial but idk what im doing

im just copying and pasting

but i really want to know what im copying and pasting

do i look up that in unity docs??

[young warren]

Type. Not copy paste. And google. Yes look up things

[lone mist]

i google each thing or the entire code?

i have no idea what im doing

[teal viper]

Things you don't understand

[cosmic dagger]

how would you even google the entire code?

[lone mist]

i dont know 😭

im just confused 😭

[teal viper]

If you don't understand any of it, it's time to go learn the C# basics.

[lone mist]

where do i learn that

[cosmic dagger]

anywhere. have you heard of or tried google?

[summer stump]

That's the issue then

It HAS to be on the one with the script

[tropic crown]

I added a collider and I started flying lmaooo

[lone mist]

[queen adder]

Hello, im new to unity and coding (Besides Lua) in general, May I ask what language unity uses?

[summer stump]

Collisions messages (like OnTriggerEnter) require a collider 🤷‍♂️

[lone mist]

C#

[queen adder]

Thank you!

[tropic crown]

WHY AM I FLYING

unity confuses me

[summer stump]

What does that mean?

[tropic crown]

when I press play I just start moving up

cannot walk or jump

[summer stump]

Is your rigidbody dynamic or kinematic? And how do you move?

[tropic crown]

very long tutorial on an fps character

[tropic crown]

rigidbody is not kinematic

Ok im stupid asf I fixed the flying thing

[lone mist]

unity learn should be cool to like

learn coding and stuff?

[queen adder]

Is this to ambitious for a first game?

Horror game!
2D

Story:
A man wonders into a hotel and finds its been taken over by zombies, with the exit locked from the outside by a mysterious force/person, with the FBI on its way to land on its roof he needs to find a way up and out.

Main Character:
David Lemmings

Hotel:
Hotel Cliton

What i will learn:
Coding, bug fixes, level design, dialouge, basic music making, basic movement, basic teleport points.

[lone mist]

idk man, i struggle to create space invaders

[queen adder]

that might just be a skill issue

[summer stump]

Anything other than roll-a-ball or something is too ambitious for a first game imo

First game should be about learning the api

[cosmic dagger]

hard to tell. this can have simple to advanced mechanics. start with simple clone games: flappy bird, space invaders, galaga, asteroid, brick breaker, single 2d mario/side-scroller level . . .

[tropic crown]

@summer stump I added the collider and still nothing...

[queen adder]

yes i will most likely be doing this before starting on it just so i can get a feel for coding and such, also side note i believe this should be a 10 to 15 minute game (Playthrough) .

[summer stump]

Show the current inspector

[summer stump]

It does't have the survival script on it

Not a rigidbody?

Wait what?

You added it to the camera?

[tropic crown]

yeah

my player has the script and the rigidbody

[summer stump]

The collider isn't on the right object

[tropic crown]

I have my collider on a child od the player

[summer stump]

The collider HAS to be on the same object as the script. Not a parent or child

[tropic crown]

ahhhh

[summer stump]

I mean, I guess you can get it from the parent of the transform... but why?

[tropic crown]

If I change it It might mess up the code of my fpc

wow it was really that easy

[summer stump]

Is this a brackey's tutorial? Why is the sensitivity so high on that camera? You aren't multiplying mouse input by deltaTime are you?

[tropic crown]

https://www.youtube.com/watch?v=f473C43s8nE

this ^

Its a bit odd how he did it all but its working so idkk

[queen adder]

The name ive came up with is "Hotel Zombie"

[rocky canyon]

its a variation of his tutorial.. even has the same mouse input * with deltaTime issue afaik

[summer stump]

Ah, yeah I think I saw that tutorial before actually, and thought "hmmmm, that DOES look awfully familiar" haha

[tropic crown]

Well its working now so ty so much I spent like 5 hours trying to figure it out already

[summer stump]

No prob! Glad it's working

[chrome crypt]

Since I can't reference a scene object in my prefab, I'm trying to reference it once the prefab clone enters the scene. So how can I set the object and function of this unity event from a script?

[cosmic dagger]

https://docs.unity3d.com/ScriptReference/Events.UnityEvent.AddListener.html

[unreal imp]

doesn't anyone know how to make the fire effect like in the gmod explosive barrels? Here is the code that does not work for me, everything related to the bool isInFire private void Start() { isInFire = false; random = Random.RandomRange(minimunHitsToDestroy, maximalHitsToDestroy); rb = GetComponent<Rigidbody>(); } void Update() { if (hitsReceived >= random) { Instantiate(explosionParticlesPrefab, gameObject.transform.position, Quaternion.identity); Destroy(gameObject); Vector3 position = gameObject.transform.position; Quaternion rotation = gameObject.transform.rotation; GameObject sherds = Instantiate(toiletSherds, position, rotation); } if (isInFire && particleInstance == null) { particleInstance = Instantiate(fireParticles, transform.position, Quaternion.identity, transform); var v = particleInstance.GetComponent<DestroyInRandomTime>(); if (!v.isActiveAndEnabled) { hitsReceived = maximalHitsToDestroy; } } }

[cosmic dagger]

also, what exactly does not work and can you describe how the gmod explosive barrels are supposed to act?

[iron lava]

can someone explain to me what this means? For some reference I had a trigger that increased my score when I went through it but now it doesn't and I get this, not sure what I did

[cosmic dagger]

https://unity.huh.how/programming/common-errors/stack-traces

[iron lava]

well its refering to this but im really not sure what I did or how to fix it?

[summer stump]

Show the inspector. Is the scoreText actually in the field?

Because that is the only thing that could be null on that line (and int cannot be, it just defaults to 0)

[queen adder]

Make sure the script isnt on another GO as well because if it is it could have a NRE

[iron lava]

the inspector for the UI score or the trigger?
Also im not sure what GO or NRE is ive only just started a few hours ago sorry.

[queen adder]

GO means GameObject

NRE means Null Reference Execption (The error message)

[summer stump]

The one with the script you just showed (which you should not call Script... but that isn't important now)

[iron lava]

I think this (I know Script is a bad Script name but it was making issues to change it)

[queen adder]

You see how it says none on text

Ur not refering to anything so the Compiler says (Null: Meaning nothing ) Reference Exception

U just need to fill in the Text field

[summer stump]

https://unity.huh.how/programming/references

This is a good site for understanding references. You are wanting a serialized reference.

Simply drag the object with the text on it into that box

[iron lava]

dang im not sure when or how I messed that up

its working now thanks

[queen adder]

Ofc brother 🙂

Also dont make everything public

[iron lava]

sorry if I wasted your time for something so silly

oh?

[queen adder]

Use [SerializeField] for something if no other code is referencing it

[summer stump]

Nah, we all start somewhere

[queen adder]

If u want something to just show in the Inspector use [SerializeField] theres no reason to make something public if you just want to modify the value from the inspector

[iron lava]

just SerializedField or SerializedField void?

[queen adder]

Like so

[SerializeField] Text scoreText;

[iron lava]

oh okay

is it bad to have them Public?

[queen adder]

To make all of them public yes

I know ur still new

So alot of this might go over ur head and thats fine (not trying to be rude)

[unreal imp]

if a barrel explode next to another the other sets on fire (and later explodes) but if the barrel is already on fire its explodes directly

[queen adder]

But unless another Script/ Class is reading or writing to the values of that script then dont make it public

[unreal imp]

srry for late response

[queen adder]

You could have another class accidently modify the fields of that script if its public

[iron lava]

I understand its a lot but I appreciate any help/advice

oh okay that makes sense

[queen adder]

Yeah ofc brother

Its better to have everything private by default

This is common practice btw 🙂

[iron lava]

I did see private void instead of public how is private and SerializedField different?

[queen adder]

private void ?

You mean the methods?

[summer stump]

Void is a return type and not relevant to variables

Methods can return something, or nothing (void)

[summer stump]

Yeah, that is a method

Which returns nothing

[queen adder]

Yeah That method should be private

But i think ur confused lol

Void is a return type

[iron lava]

so why SerializedField over private

[queen adder]

Private public are access modifiers

[summer stump]

It is WITH private, not instead of

[queen adder]

U dont do [SerializeField] on methods

[ivory bobcat]

If you don't see the public or protected then it's implied private. Accessors are required for members of a class.

[summer stump]

But variables DEFAULT to private, so if you don't specify, it is private

[queen adder]

You do that on fields / properties

[iron lava]

oh okay

[queen adder]

Ok so remember how private means nothing else can see it?

[iron lava]

so different tools for different tasks basicly (im sure those are bad words to use as an exaple)

[queen adder]

That means even Unity cant see it. (This isnt entirely true but...)
So u want a way for unity TO see it.

"[SerializeField]" Does that for u without having to make it to where anyone can modify the fields / properties

[iron lava]

I think I understand? Im sure it'll bite my butt one day and then ill understand fully

[queen adder]

Like i said ur still new

So most of it will go over ur head but as long ur doing research and actually trying like u are! You'll do great!

[iron lava]

Ive mostly been fallowing YouTube and step by step guides but If I wanna branch out a little wheres the best place to get general guides or a place to learn what the code means so I can kinda "kit bash" things together. I hope that makes sense sorry if it doesn't im pretty tired and just wanted to finish this project before I pass out

[queen adder]

Yeah best practices arent learned overnight. So give urself time to understand the concepts. Ur doing really good so far tho

[iron lava]

Thanks man. and thanks for the help, im sure ill darken your doorstep some other time but only time will tell.

[cosmic dagger]

when a barrel explodes, have it check for other barrels within range and raise an event or call a method. that method (on the barrel) will check if it's on fire and act accordingly: explode, or set itself on fire . . .

[unreal imp]

Yeah 😭

[tiny terrace]

can I use lerp in order to change my rigidbody's velocity? i want it to de-accelerate until it reaches 0 within a timeframe

[teal viper]

Sure.

[lean basin]

I have a gameobject with script and collider. How do I get Collider component using the script? The collider could be anything. It could be sphere, it could be box, but there will always only one.

[river roost]

GetComponent<Collider>() or GetComponent<Collider2D>()

[lean basin]

oh this works! thank you.

[supple wasp]

How to make a joystick?

I want to make the R joystick move the character and the other L joystick move the camera

[sullen rock]

is FixedUpdate completely independant from FPS? like, even if I have 30 fps, fixedupdate will always be 50?

[keen dew]

yes

[fossil drum]

Yeah it will do multiple FixedUpdate's in a frame then to catch up. Which can also cause the FPS to drop lower again.
https://docs.unity3d.com/ScriptReference/MonoBehaviour.FixedUpdate.html

If the application runs at 25 frames per second (fps), Unity calls it approximately twice per frame, Alternatively, 100 fps causes approximately two rendering frames with one FixedUpdate. Control the required frame rate and Fixed Timestep rate from Time settings. Use Application.targetFrameRate to set the frame rate.

[sullen rock]

thats fine, my issue is - Im doing sort of an endless runner where I need to generate "blocks" of th environment procedurally and when I do it frame-dependantly, there are small spaces between the blocks when change rapidly, Im hoping to solve this by doing all this login in fixed frames instead

[fossil drum]

It will, but you could also do the math to fix it in Update, but that will be a bit more tricky. FixedUpdate will be an easy fix to your problem.

[sullen rock]

seems to have done the job, yeah

[subtle gull]

new to unity, any good places to learn? or is youtube my 1 place to go ? XD

[tender flame]

anyone knows a good way to play videos in unity?

the default Video Player is lagging freezing or skipping frames

[teal viper]

Must be using it incorrectly.

[tender flame]

What do you mean by that?

[teal viper]

That you are not using it correctly.

The default video player works properly for most people. If it doesn't work for you, there's something with your setup or code.🤷‍♂️

[fossil drum]

Or way too high resolution/bitrate.

[gray basin]

Hey im trying to implement accelerating and deccelerating in my movement code but i dont understand why this isn't working:

        rb.velocity = new Vector3(input_x * move_speed,0,0);```

"move_speed" just gets instantly set to "max_move_speed"... am i using MoveTowards incorrectly or what?

also input_x is just the "horizontal" built in axis

[ivory bobcat]

Log acceleration. If anything, you may need to have it be relative to delta time.
acc * Time.deltaTime

[gray basin]

acc is constant so the log always says 1

if i multiply by deltatime i just move very slowly instead which i dont understand. Shouldn't it move towards max_move_speed?

[keen dew]

It starts the movement from 0 every time

it should be move_speed = Mathf.MoveTowards(move_speed, max_move_speed, acc);

[gray basin]

yeah i just realized

[static cedar]

Some quick rundown of different protection levels.
Public - Anything can see it.
Internal - Only the current assembly the class belongs to can see it.
Private - Only the class/struct/interface it belongs to can see it.
Protected - Same as private but any classes that inherit from the class it belongs to can also see it.

Some more niche protection levels.
Protected Internal - Internal OR protected.
Private Protected - Internal AND protected.

[ivory bobcat]

If you aren't running it in fixed update and do not want it frame bound, make sure to multiply the acceleration by delta time.

[gray basin]

yeah yeah thx

[dusky vigil]

Hello, I have a problem with my pickup function (pick and drop weapon system) . When I pick a weapon from the ground the position of the weapon remains the same even if I change it in the script. The weapon container is to parent and unparent weapons to it, it's an empty obj. pls help 😦

[fringe pollen]

Is your weapon container under the camera?

[dusky vigil]

no, they both have the same parent which is an empty object used for camera recoil

[rancid tinsel]

why is VS telling me that i need to close a bracket when i have 14 brackets in total

im so confused

nvm it didnt like the public

[slender nymph]

yeah you cannot declare a public variable inside a method

[rancid tinsel]

makes sense

i was trying to figure out the syntax for the array

cuz i completely forgot

i got it now tho

[jolly pendant]

UnityEngine.GUIUtility:ProcessEvent (int,intptr,bool&)

[rancid tinsel]

https://gdl.space/dosijiqupa.cs any idea why line 46 is giving me this error?

excuse the terribly messy code

[wintry quarry]

textbox.text = Scenario[0]; is the line.
So 0 is out of range.
That can only mean that Scenario is an array with length 0

i.e. your array is empty

[rancid tinsel]

but I have 3 strings in that array no?

or did I mess something up

[wintry quarry]

how?

[wintry quarry]

string[] Scenario = {"You wake up in the middle of the street. You have no recollection of who you are apart from your name. The only people you see out are a group of people drinking. Do you talk to them? (A = Yes, B = No)", "", "" };?

This?

[rancid tinsel]

yes

[wintry quarry]

This is completely unrelated

you simply declared a local variable here also named Scenario

this will not affect the Scenario member variable

If you wanted to assign the member variable you need to omit the type

just do Scenario = {"whatever"};

[ivory bobcat]

Dirty solution: guard statements

[wintry quarry]

well a guard statement would stop the errors but won't fix the script (won't make it do the right thing)

[rancid tinsel]

ohh, i was confused cuz whenever i would delete the string[] part it would start giving me a bunch of formatting errors

[wintry quarry]

such as?

[wintry quarry]

because you have string[] inexplicably on the line above?

you're also possibly missing semicolons on those lines

[rancid tinsel]

oh i didnt see that

deleting that gave more errors tho

[wintry quarry]

keep going

they are probably real errors.

[ivory bobcat]

Live 79 and 80, remove the type unless you're wanting to declare new types in that scope specifically

If you continue to get errors, you're probably using them before assigning them

[rancid tinsel]

what on earth is going on

how am i missing 3 ;'s in 1 line

[wintry quarry]

you appear to me missing semicolons? Can't say without seing the code

[rancid tinsel]

https://gdl.space/yupobehife.cpp

79 and 80 are the Scenario and ScenarioA arrays

[wintry quarry]

Scenario = new string[] {"You wake up in the middle of the street. You have no recollection of who you are apart from your name. The only people you see out are a group of people drinking. Do you talk to them? (A = Yes, B = No)", "", "" };

you can only use the syntax without the new part if you're declaring and assigning in the same line

[rancid tinsel]

that worked

[rancid tinsel]

oh i see

is that for arrays specifically or?

[wintry quarry]

only arrays have the ability to do the special syntax without new afaik

[swift crag]

oh, neat

[rancid tinsel]

would it go to the else on the first time this is run?

the way I understood it was that if the IF goes through, the ELSE doesn't and vice versa

[swift crag]

correct

in general, in a chain of if / else if / else, the first one that succeeds is run

everything else is skipped

else always succeeds

[rancid tinsel]

it seems to be doing both though

[swift crag]

doing both what?

[rancid tinsel]

as in doing the IF and then doing the ELSE in 1 run of the code

[swift crag]

and why do you think that's the case?

have you, for example, added some log statements to see which path is being taken?

perhaps the code is just running twice

[rancid tinsel]

because the ChoiceMadeA thing changes the text in the textbox, and it switches to it instantly

hmm maybe

only does one debug thats right below it tho

[rare basin]

how to move an UI object toward's mouse position if the mouse is on the edhge of the screen?

    private void Update()
    {
        Vector3 mousePosition = Input.mousePosition;

        bool mouseOnEdge = mousePosition.x <= edgeMargin ||
                   mousePosition.x >= Screen.width - edgeMargin ||
                   mousePosition.y <= edgeMargin ||
                   mousePosition.y >= Screen.height - edgeMargin;

        if (!mouseOnEdge) return;

        Vector3 worldMousePosition = Camera.main.ScreenToWorldPoint(mousePosition);
        Vector3 moveDirection = (worldMousePosition - map.position).normalized;

        map.Translate(moveDirection * mapSpeed * Time.deltaTime);
        clouds.Translate(Vector3.left * cloudsSpeed * Time.deltaTime);
    }

doesn't work, always moves to the same direction (left bottom cornet idk why)

[rancid tinsel]

https://gdl.space/kizetunelo.cpp this is the code, i dont think it should be running twice

[swift crag]

and is gamescreen.choicemade starting out false?

[rancid tinsel]

its starting out true 😭

let me check why

[lunar grove]

Anyone know a proper way to code VFX particle animations with trigger?

[swift crag]

that's very vague

are you trying to play a Visual Effect when a trigger collider is entered?

[lunar grove]

Actually I want to play a visual effect when I press a button, while the visual effect which is a slash is coded to damage enemies when it comes contact into them

via trigger collider

Do i use the particle trigger or do I use another way?

[swift crag]

i don't know what a "particle trigger" is

Oh, I see

This is a ParticleSystem

[lunar grove]

yeah yeah

[swift crag]

https://docs.unity3d.com/ScriptReference/MonoBehaviour.OnParticleTrigger.html This does sound like what you want

It looks like OnParticleTrigger is run when any particles from a ParticleSystem on the same game object enter or exit a collider

you have to ask the system for a list of particles that just entered or just exited

[lunar grove]

Is it worth using the particlesystem trigger though? Because I've seen some people say that they just prefer to use collider to do damage to enemies in games

like using collider around effects

[swift crag]

It would be more consistent.

the exact paths of the particles wouldn't matter

[lunar grove]

Sooo do I just attach a collider to the visual effect and code it that way?

[eternal falcon]

[rancid tinsel]

the errors were in my IDE

it wasn't telling me what the issue was

since the issue wasn't semicolons, it was me messing up syntax for arrays

(IDE already configured)

[swift crag]

you'd just attach it to the same object as a particle system or visual effect, yes

[swift crag]

Syntax errors can cause very confusing errors.

[lunar grove]

Add component mesh collider?

[thick goblet]

When I SLOWLY left click to play my punching animation while both running and idle everything works. I'm able to move again. Except when I start spamming left click to punch while idle then suddenly my moveSpeed doesn't reset correctly back to 6f and I'm stuck frozen. Anyone know how to solve this? https://gdl.space/origofezut.cpp for the code

Could it be a bad Input.?

[swift crag]

Whatever collider shape you need. I would expect this to be a primitive collider

[polar acorn]

@thick goblet When you start punching, it stores your current move speed in a temporary variable and then sets it to 0. After a delay, it returns it to the stores variable. If you press the button while the coroutine is already running, it will store 0 (the current speed) and set it to 0. The first coroutine finished and sets it to its stored value of 6, then the second one finishes and sets it's stored value of 0

[swift crag]

since you're just showing some particles, not drawing a mesh

[thick goblet]

I think I understand digiholic. I will try to solve it now

Thank you (Might not be able to though)

[lunar grove]

I think the cube would be best for a slash VFX collider?

[wintry quarry]

basically float originalMoveSpeed = moveSpeed; don't do this in the coroutine. Save the original move speed in Start for example. You only need to do it once.

[swift crag]

A box is a classic hitbox shape, yes

[lone sable]

Is there anyway I can hook into a "On Selected" aspect of a UI Component via code? I have a slider I want something to happen on selected/deselected with. I know I could do Animation Events, but, yeah.

It seems I can't hook into this event?

[swift crag]

along with spheres and capsules

[lunar grove]

Yeah i think a lot of games actually use box as a hitbox shape to be more efficient if i remember seeing one gamedev behind the scenes

[thick goblet]

That solved it perfectly. Thanks a lot I spent like 2 - 3 hours for this system to work.

[lunar grove]

Thanks a lot @swift crag , you're response was a real eye-opener!

[swift crag]

no prob (:

Oh yeah, one other thing to consider: you could use a mesh for the collision and as a source for the particles

you don't need an actual mesh renderer

(you could just turn it off after dragging the model into the scene)

[lunar grove]

Oh okay thanks for the extra tip!

[swift crag]

oh, wait, the particle system's "Mesh Renderer" emission shape...explicitly needs the renderer

Still works fine if the renderer is off

It does have a "mesh" mode as well, but you will need a Mesh Filter component on the object anyway so that the Mesh Collider works

so at that point it's probably just easier to turn off the renderer on a model you dragged in

two of the same object; the one on the left has its renderer off and a particle system with an Emission shape of "mesh renderer"

mmmm error shader

[lunar grove]

oh okay!

thanks again!

so that's via the particle system?

[swift crag]

Yep.

This will emit particles from each vertex

so, for example, you could make a half-torus mesh and use that as the hitbox

and also emit particles from it

[lunar grove]

Ah I see super helpful for more complex and detailed game projects

thanks for the heplful insights and information

[vestal valve]

What is the use of [System.Serializable] ?

[slender nymph]

the Serializable attribute lets certain serializers know that the type can be serialized

[swift crag]

By default, types won't be serialized, since you might not have intended for them to be saved and loaded

[slender nymph]

and if your next question is "what is serialization" it's basically converting an object into a format that can then be saved/written to disk

[lunar grove]

So I have this preset slash vfx that uses particle system, do I have to use the animator or a different way to make it so the slash vfx gets triggered upon mouse click?

[calm coral]

Thanks

[swift crag]

also, [System.NonSerialized] is used on fields to say "don't serialize this"

I like using this for classes that need to store some runtime information

for example...

[System.Serializable]
public class BlendshapeInfo {
  public string blendshape;
  [System.NonSerialized] public int index;
  public float value;
}

I ask the skinned mesh renderer's shared mesh for which index that blendshape name corresponds to at startup

so that I don't have to do that every time I update the blendshape

The index should not be serialized because there's just no point -- the value will only be known at runtime

[lunar grove]

Where are particle effects usually put into a scene?

or are they just called from the assets to play?

[sly bolt]

i have set the numeric values for both the spheres resembling their appearance and they are assigned properly while introduced into scene , but as soon as they collide numeric values of both the spheres turns to zero unexpectedly even though i have no modifications to the numeric values (except the image here).
please provide help this is like my 5th time asking.

[swift crag]

If you're using the old ParticleSystem, then everything is configured on the ParticleSystem component

The new Visual Effect Graph package has you attach VisualEffect components to things to actually play the effects

but the definitions are stored in assets

[lunar grove]

because I have this game object with a the particle system that generates the attack VFX, and I attached it to my character, is that optimal or no?

because the cube collider

or box collider hits the enemies and damages them without the vfx playing

is there a way to synchronize the hitbox appearance with the particle system vfx?

[thick goblet]

I added a transform rotation to flip my player along with it's child objects so that the x faces the directions it's moving. I'm planning to implement fighting systems etc. Is this method a problem or is there a better way to do it?

[swift crag]

you would want to turn the collider off when the particle system isn't playing

or just ignore the messages

[lunar grove]

is there a code to turn collider on and off?

[rich adder]

wassup with -360 lol

why not just 0 / 180

Your jpg quality is bad

.

here

debug logs are not present in that one but i can assure the numeric value sets to zero right after collision is executed

[uncut dune]

yo guys something is up with my line renderer

this is the code

and the ShootHitScan(); is being called in the animator

the wrong thing is

as u see

lr.SetPosition

is being set incorrectly

this is the debug

of the pos

this is the actual result

any idea?

from what I have tested there is a big delay

it saves an old pos

but I have no idea why

[polar acorn]

You're setting the line renderer positions of the prefab

Which means it gets applied to the next trail

Each one is showing the line of the previous shot

[uncut dune]

OHHHHHHH

IT WAS BECAUSE OF A

LETTER

THANK YOU SO MUCH

[polar acorn]

Also, why is SniperTrail of type GameObject when literally the first thing you do is get a component from it? Make the variable of type LineRenderer and save the getcomponent call

[sly bolt]

@calm coral sorry for ping , here are the scripts

if you wish to see debug logs in runtime

[calm coral]

Fine but that's a lot of scripts I can't spend that much time to analyze it. And I'm experienced in 3D not 2D

[uncut dune]

can I still use instantiate on a line renderer?

[polar acorn]

Yes

[sly bolt]

alright no problem , thanks for showing interest tho

[ashen ferry]

you want for player sphere to collide with npc one and smaller number sphere should disappear and reduce bigger sphere number?

[sly bolt]

yes precisely, and it happens through numeric value assigned to them which reset to zero for some reasons when they collide

[wary sable]

Would running While(True) be the same as While(enabled)?

[wintry quarry]

no

[ashen ferry]

Your current setup is messed up bro u gonna need to go bald im afraid

[rich adder]

copy

which one is the collision script

like this part

[sly bolt]

last one (numericsphere)

[rich adder]

is SpawnerNumericValue? this what sets to 0 ?

[sly bolt]

actually both SpawnerNumericValue and launcherNumericValue gets set to zero

[wary sable]

Would you be willing to expand a little?

[rich adder]

so this
?
int SpawnerNumericValue = randomizedValues[randomIndex];

i dont see it being set anywhere else

unless im blind

oh wait this setting a local one..

ur aware of that yes? just checking.

[wintry quarry]

while(true) will run forever.
while(enabled) will only run if and while enabled is true

[rich adder]

adding int in method makes it a local variable, so you're not changing the original SpawnerNumericValue
@sly bolt

[sly bolt]

yes that i used to spawn spheres with random value

[rich adder]

where tho?

[sly bolt]

i dont know it did seem to set the numeric value in debug logs , i could be wrong tho

[ashen ferry]

u got 50 sprites to display numbers btw?

[sly bolt]

as in the scene or scripts?

[sly bolt]

yes , after the operation because largest possible number that can be obtained is 49

[rich adder]

this

[sly bolt]

actually it wont be 50

something like 48

[rich adder]

where is this happening

[sly bolt]

because numbers are starting from 2

[ashen ferry]

theres 3d text or something u could look into and just set its text to a number of sphere instead of that many prefabs

[sly bolt]

in the scene i have this (sphere_spawner) script attached to empty gameobject

and if u mean where the randomising is happening then its in the bottom block of code in the same script

void shuffle

[sly bolt]

i thought you need 3d objects for that

idk not sure

[swift crag]

there's nothing really "special" about 3D and 2D

you can slap a TextMeshPro component onto an object to have text appear on it

[wary sable]

I suppose I should have expanded my question more... I am writing a behavior designer node (rather converting an existing script I had into a node), and in that script is an IEnumorator with a while(enabled) loop (enabled is a part of monobehavior // not defined in my script). When making a node you have to change the parent class / interface for the class so I cant use monobehavior items like enabled. Would a While(true) loop be an acceptable replacement?

[sly bolt]

ive already made the necessary prefabs so it would be unnecessary at this point

unless they are creating a problem

i did read about textmeshpro but i thought it was only for 3d objects so went with this approach

[ashen ferry]

but u instantiate whole ass new sphere when u need to change the number

[sly bolt]

yes that is my mistake due to the misunderstanding

i will take a look into how it works and rework the project , but i dont understand why the collision is resetting the value

[ashen ferry]

I still think thats still the most valid option rn to go with now you know what mistakes u need to avoid rewriting the logic

[rich adder]

I just wasnt seeing where the number was being passed on

only seen NumericSphere script has such an assignement of numbers

but idk the value because thats set inside the inspector ?

[wary sable]

I suppose since the loop is supposed to be a part of a coroutine for a main task, I can just use the TaskStatus bool to toggle the loop, since while wouldn't necessairly stop running when the node is "turned off"...

[sly bolt]

no its not set inside the inspector , the launchernumeric value is based on input and spawnernumeric is basically any value randomly between (10-99) i believe i made them public because of access issues

[ashen ferry]

wtf is node is that godot I smell

[rich adder]

the only place I seee SpawnerNumericValue being changed is a local variable in SphereSpawner

I don't see where else this is modified besides
Initialize

which is being passed in the same SpawnerNumericValue of whatever this script is on

[wintry quarry]

It depends what you expect it to do

[sly bolt]

and in the numericsphere script inside collision code block to carry out the operation

[wary sable]

It is a method that syncs root motion animations with nav mesh agent movement, so it needs to run alongside another movement script

[rich adder]

yeah but where is SpawnerNumericValue being changed exactly? Unless I'm blind / missing something

[wintry quarry]

right but it depends how you want the loop to behave. If you want it to be tied to the enabled state of some MonoBehaviour, true will not replicated that

[sly bolt]

its changing after colliding with launcher_sphere (one being launched by user)

changing to zero , even though it shouldn't

[rich adder]

this ?
SpawnerNumericValue /= launcherNumericValue;

you tried debugging both values before the operatioon and result ?

[distant current]

Can anyone help me with this? My buttons are not working even though there is an event system. It all started ever since I try to load scene additively

[sly bolt]

no actually its changing right after collision (before this line is even compiled) concluded from debug logs

instantly after collision

watch this clip

[wintry quarry]

select your event system and watch the preview window while you mouse over the button.
It will tell you which object is blocking it

[rich adder]

if (SpawnerNumericValue % launcherNumericValue == 0)
                    {
Debug.Log($"SpawnerNumericValue is:  {SpawnerNumericValue} & launcherNumericValue is : {launcherNumericValue}");
                        SpawnerNumericValue /= launcherNumericValue;
          Debug.Log($"SpawnerNumericValue is:  {SpawnerNumericValue} ");
                        SetSpriteBasedOnNumericValue();
                    }```

@sly bolt

[distant current]

Okay, Im gonna do that, thanks!

[sly bolt]

do you want me to make these changes?

[rich adder]

yes lets see what the results are in the code

[sly bolt]

1 sec

[rich adder]

launcherNumericValue is likely 0 like it says

[distant current]

it doesn't show up here

[sly bolt]

yes initially its not zero but after collision it turns to zero along with spawnernumericvalue

[distant current]

I also tried to put my event system in hometown scene itself but still doesn't work

[sly bolt]

and yes as i anticipated the code changes didnt affect anything because the value getting to zero happens instantaneously after collision so other part of script wont execute because value is zero and i get the error "attempt to divide by zero"

[rich adder]

yes because its 0 when it hits the %

[ashen ferry]

that modulus operator is giga random afaik lol

[rich adder]

you cant do % 0

[sly bolt]

yep thats the exact problem

[rich adder]

well i assumed it wasnt because its public so thought it was set in inspector or somehting

[sly bolt]

the numeric values are completely fine until they collide and get set to zero for some reasons

no iirc i just set them public to get access in other scripts

[rich adder]

launcherNumericValue isn't being set anywhere

so if its 0 in the inspector by default, it wont be changed

[sly bolt]

its the input (2-9)

[rich adder]

where is that

where do you set it according to inputs

[sly bolt]

first script, in the for loop

[sly bolt]

.

[rich adder]

SphereLauncher ?

[sly bolt]

yup

[rich adder]

I dont see launcherNumericValue being set

[sly bolt]

yes , its taking the value of 'value'

basically taking from input user entered

[zealous oxide]

https://hastebin.com/share/goqinafadu.csharp hey friends, in my 2d platformer, i've changed my player characters dashing ability (as per the screenshot) to be based on the direction the character is currently traveling (as per the code). if the character is going left or right, the dash goes the expected distance, left or right. if the character dashes up or diagonally up, it goes FLYING. now, i'm wondering if I would have had better success going back to my original dashing function but changing the code to allow for a direction based dash (as it is in the screenshot. the screenshot is from before my update, the haste bin is after my update).

[rich adder]

you're never changing that variable though
you're just doing int index = launcherNumericValue - 2; // Subtract 2 because the array is 0-based.

[sly bolt]

I cross checked if launched spheres have desired numeric values after launched and they do so i can assure their value is not zero initially

[sly bolt]

in the function
void launchsphere(launcherNumericValue)

its taking value of value

[rich adder]

launcherNumericValue is just a parameter name for that method
where are you changing the launcherNumericValue variable that you later use for division

[sly bolt]

no im not changing it im basically getting input from user and storing it in variable value in first script and then taking that variable in the function
void Launchsphere (int launcherNumericValue)

[rich adder]

ur instantiating it without a value or am i missing something
GameObject newBubble = Instantiate(bubblePrefabs[index], transform.position, Quaternion.identity);

value types default to 0 when not assigned

so probably is 0 when u spawn it

`public class NumericSphere : MonoBehaviour
{
private Rigidbody2D rb;
public float movementSpeed = 20f;

public int launcherNumericValue;
public int SpawnerNumericValue;

`

launcherNumericValue
isnt assigned but then its 0

[sly bolt]

it has the index value which is declared as launcherNumericValue - 2

[rich adder]

we're talking about the instantiated ball no?

NumericSphere

[sly bolt]

yes

[rich adder]

 public void Initialize(int value)
    {
        SpawnerNumericValue = value;
        Debug.Log("Numeric Value: " + SpawnerNumericValue);
    }

where is launcherNumericValue

cause if its not assigned anywhere else, explains the 0..

[sly bolt]

i am getting the value of it in the inspector (whatever i input from keyboard)

[rich adder]

now im hella conusfused tbh lol

ima take a quick tea break brodda

[ashen ferry]

I can write skeleton of what u exactly need to do with the spheres not much progress is being made here lmfao

[rich adder]

the code says the value is 0, i trust the compiler

this is one of those examples maybe splitting the code so early into different scripts can do more harm than good

[sly bolt]

what i meant here is the launcher_sphere and spawner_sphere both have their respective values set which is not zero but both values change to zero after both of them collide with each other

[rich adder]

thats why am askign where it being set at all, let alone 0

you might just be looking at the defaulted / spawned one that might have 0 value 🤷

[sly bolt]

you can get idea of what im trying to say in this clip , read the debug logs

[sly bolt]

but the spawned one does have none zero value

initially before collision

[rich adder]

values don't typically change themselves, so somewhere its being set to 0 and if its not you're looking at the wrong object

[sly bolt]

no i wasnt looking at object but the debug log

newBubble.tag = "LauncherSphere";

Debug.Log("launcher Numeric Value: " + launcherNumericValue);```

i set the log after launcher sphere is spawned and the value is indeed non zero

[rich adder]

this isnt the value on the spawned bubble tho..

[sly bolt]

u can watch the clip or i can record new one

[sly bolt]

then which one

[rich adder]

SphereSpawner

SphereSpawner may have the correct value but the new object probably does not

because i dont see it being passed anywhere

if you did newBubble.SpawnerNumericValue = SpawnerNumericValue

it would make sense because inside the NewBubble(NumericSphere)
is where you're doing division

[sly bolt]

hold on let me record and show the scene

[crisp gate]

how do i reset my main camera position if it exits a certain x/y position?
let's say if the camera's position is >= 1080, it transforms back to x = 0, y = 0

[rich adder]

assign it the position you want

if(camera.transform.x > myXLimit || camera.transform.y > myYLimit) camera.transform = Vector2.zero;

etc

[crisp gate]

ooo

[swift crag]

instead of recording video after video, why don't you trace the path the data takes?

[swift crag]

you should be able to easily follow that number through your code

[rich adder]

it would help if you did Debug.Log(name + valueOrWhatever) but I assume you're just debugging the values on spawner 🤷 like I said, the spawned object that does the division still spawns with a 0 value, why dont u click one of the balls and view the inspector for the current values

its really not a hard problem I think there is just misunderstanding

[sly bolt]

maybe let me see

[weary crystal]

Why!??

[rich adder]

anything after-2021 doesn't have learning project templates

[weary crystal]

Huh, so no microgames?

[rich adder]

not for that version

[weary crystal]

So should I downgrade? I'm a beginner.

[rich adder]

its not degrading but it probably is better to use a version that closely matches the tutorials/videos learning

[swift crag]

downgrade, not degrade :p

[weary crystal]

Okay, damn should've known before installing it, thanks.

[weary crystal]

Oop, my bad.

[swift crag]

but yeah, the 2022 LTS is missing the project templates

i dunno what the deal is with that

the 2021 LTS will work just fine

[rich adder]

You can proabbly still open the projects if they are hosted on the website

but use 2021 as its less buggy anyway

I literally already made 3 bug reports on 2022

idk why it was so shotty

[swift crag]

well, we are (relatively) close to the LTS's release

[weary crystal]

Oh yeah, I reinstalled Unity just to get rid of the package manager problems, it just kept loading the packages, I couldn't use any assets.

[swift crag]

an LTS is just a version that's going to get patches for longer than usual

[weary crystal]

So the problem is with the version, imma just install the 2021 now.

[rich adder]

true but 3 patches already and they still havent fixed the pink fonts on my macos xD

[swift crag]

where's the "works on my machine" sticker

what version of macOS are you running?

i'm one update behind, I think
