What exactly do you not understand, and what have you tried looking up? Doing things on your own without a tutorial is good, but its also good to search online for resources and references

tardy scroll
#

What function do you usually use for rotation during/according to movement, Euler or another?

trim schooner
#

depends what's being moved and how

tardy scroll
#

I've set up movement for a player object but I also want it to rotate in the direction it is moving.

trim schooner
#

yes, but you can make things move in different ways.. mainly via physics or not

hexed pecan
#

Also is it 2D or 3D

trim schooner
rigid island
tardy scroll
#

Yeah, forgot to say it's 3D (first project) and I'm using Rigidbody

rigid island
tardy scroll
#

Thanks, I'll try MoveRotation, I had been using just Move for the rigidbody

rigid island
#

oh ya forgot Rigidbody.Move also exists, never used it but seems this also lets you rotate ?

#

Quaternion targetRotation = Quaternion.LookRotation(movementDirection);
(only do this if you have moveDirection inputs otherwise you get an error setting rotation to 0)

tardy scroll
#

yeah, Move also seems to rotate

hexed pecan
#

Wdym?

tardy scroll
#

but not in the correct direction, like in the opposite direction

hexed pecan
#

Pretty sure that rb.MovePosition/MoveRotation are meant for kinematic rigidbodies

rigid island
#

iirc MovePosition is

hexed pecan
#

Not sure if they detect collisions properly for non-kinematic ones

rigid island
#

never used it tho

hexed pecan
#

Oh right, forgot that exists

#

I was thinking of MovePosition

rigid island
#

ya movePosition is Kinematic only

#

moverotation both iirc

hexed pecan
#

I assume Move to just do MovePosition + MoveRotation

#

Why do none of those docs say anything about collision detection

#

Like does it respect collisions or no

rigid island
#

I think it should as long its not kinematic i suppose

#

MoveRotation only mentions interpolation 🥹

#

best thing is for op to tryitandsee

#

Does anyone happen to know why you cant assembly assembly like inventory -> item -> guid because you cant reference GUID in Inventory?

rigid island
#

can you explain a bit more 😅

karmic stone
# rigid island "cant assembly assembly" ?

i meant like you have to reference the GUID assembly in every single assembly you want it to be used in, rather then having the assembly already having access to it due to already having access to something that uses it.

#

if you try to use GUID in inventory with this reference path you get "Could not find definition for GUID"

#

if Inventory depends on item, and item depends on guid, shouldnt by transitive property, inventory depends on guid

rigid island
#

ahh assembly definition files?

karmic stone
#

yeah, for seperating code

rigid island
#

so do you need to add explicitly GUID assembly to Inventory ?

#

I've only used asmdef for some assets

karmic stone
#

yes, for it to work right now. feels like im having to reference like for item interaction, Item interaction -> GUID, Item -> GUID

rigid island
#

isn't that normal ?

karmic stone
#

I mean i would think that if i tell it hey, reference the item class, that means it should also reference the SerializableGUID, because thats what item references

#

but it doesnt work that way, i need to have 2 assembly references, GUID, and Item

rigid island
#

like inheritance ?

karmic stone
#

yes

rigid island
#

oh no idea I would assume would not be good the way asmdef are designed to be modular

#

It would have loads of bloated dependencies

karmic stone
#

unity docs show this picture as a reference, but its really confusing

image.png
rigid island
#

yeah one references only what it needs

karmic stone
#

yeah, but my interpretation is that main could see Library.dll, just that Stuff cannot see Main or Thirdparty, and library cant see any of it

rigid island
#

I suppose its no reason library should know about thirdparty and main

karmic stone
#

The reason i need it this way is that ALL my systems use GUID as a way to seperate A. Items, and B. Player instances.

naive swallow
#

Netwonsoft doesn't give two shits what my game does

#

it just exists and I use it

karmic stone
#

Yes, but in this case, why can Main.dll not see Library.dll?

rigid island
#

because main isnt using it

#

suppose you delete Stuff., we no longer use this code, now main has to error too for what reason

naive swallow
#

Well, if Main had a dependency on Library, you'd need another arrow. In this case, Main uses Stuff which uses Library. The point is that each assembly only cares about the things it, specifically, uses

#

This way, if you were maintaining Main, you wouldn't care what libraries Stuff uses, as long as Stuff has those dependencies properly set, all you'd need to do is add the dependency to Stuff

karmic stone
#

Ahhh, ok modular code is the main purpose, i was thinking about it more so for how unity recompiles things. thank you for the explaination digi, and thanks for the help nav

naive swallow
rigid island
#

yup one main stink about having everything in CSharp-Assembly

#

change 1 line, ALL scripts recompile

karmic stone
#

yeah, i ran into using assemblys to help speed up editor compile times, as quicksaving scripts hurt me, even for a small number of scripts

#

(also remember to try to code around disabling domain reload)

rigid island
#

the benefit of speedy recompiles and modular libraries, at cost of having to compartmentalize everything

rigid island
#

but thats huge

#

should've been default lol

karmic stone
#

better to annoy the people that have to change it, then to deal with the people who bring issues that are only due to domain reload being disabled

rigid island
#

yea true, cause of statics not resetting state and all that

karmic stone
#

yeah, tho for statics that are just databases, not resetting state actually helps XD

rigid island
#

gone are those days lol now its either SOs if I dont mind reset beginning exe or file for permanent

blazing tiger
#

Has anyone come up with a better world partitioning than chunks for games with large terrains and structures that span several chunks?

#

Cause it just feels messy

#

Sure you can calculate how many chunks a structure occupies during generation and generate all of them or defer the changes

#

And make chunks dependency so that the entire structure is loaded\unloaded but I can't help but wonder if there's just a better partitioning for this kind of game

You should probably not use System.Numerics in a Unity project

#

Unity's got their own versions of numbers for a reason

hot ledge

seems like they're intentionally avoiding UnityEngine in some scripts

yeah without editing any of the files, this is what it spits at me when I try to compile

fiery steeple
# hot ledge how do I avoid that when the code is from SQL4Unity?

I don't know what that is but usually it has to do with a setting related to suggestions and I guess when you typed Vector3 it suggested you multiple Vector3 from different library / namespace and the first one is System.Numerics and you accepted that one instead of the one made by Unity.

hot ledge
#

I should clarify maybe

hot ledge
hot ledge
# hot ledge ._.

this was from my attempts at fixing it by editing the asset directly

#

which I'm kinda hesitant to do because this asset is for doing SQL database queries in any version of unity

#

which sounds like something that shouldn't be messed with lol

white dew
#

Im trying out assemblies for the first time to try and get compile times down and maybe I'm doing it wrong but to test it out I made a folder with only one monobehaviour script in it and the assembly definition and it is still taking 30+ seconds to compile.

Compilation is usually the faster thing during assembly reload.

Hi everyone!

I’m working on a Unity project where I need to perform a Raycast, but I want it to only check for intersections with one specific Collider and ignore all others (with same layer). Essentially, I want to know if a Ray intersects a particular Collider without checking against every Collider in the scene.

Thanks!

Anyone know why the x axis is continous, but the y isn't?

public class Chunk : MonoBehaviour
{
private float NoiseHeight(float worldX, float worldY, int seed, float scale, int heightMultiplier)
{
    float xCoord = worldX * scale + seed;
    float yCoord = worldY * scale + seed;

    // Generate Perlin noise value (between 0 and 1)
    float noiseValue = Mathf.PerlinNoise(xCoord, yCoord);

    // Center around 0 and apply height multiplier
    return (noiseValue - 0.5f) * 2 * heightMultiplier;
}

private void GenerateVertices(int x, int y)
{
    int chunkX = (int)transform.position.x;
    int chunkY = (int)transform.position.y;
    float scale = 0.01f;
    int seed = 0;
    int heightMultiplier = 75;

    for (int i = 0, xi = 0; xi <= x; xi++)
    {
        for (int yi = 0; yi <= y; yi++, i++)
        {
            // float height = heightMap[xi, yi]; // Get height from the heightmap
            _vertices[i] = new Vector3(xi, NoiseHeight(xi + chunkX, yi + chunkY, seed, scale, heightMultiplier), yi);
            // _vertices[i] = new Vector3(xi, 0, yi);
        }
    }
}
}
leaden ice
#

oh wait I see where i is incremented

viscid plaza
#

yeah I should probably change that to make it more readable

leaden ice
#

So you're asking about the holes?

viscid plaza
#

It's almost as if the rows are exact clones of themselves.

#

The x is perfectly continuous, but the y isn't.

leaden ice
#

Yeah that cloning part is happning because you're sampling Mathf.PerlinNoise at integer intervals

#

I think

viscid plaza
#

Yeah there are a lot of duplicate xCoord and yCoords

image.png
#

So it's somehow just generating the same row a bunch of times.

viscid plaza
#

Turns out I am the dumbest guy. I was using the chunks height in the world (always 1) to determine it's y position (y as in y on a 2d plane).

How to I invoke a method only when the left mouse button is clicked, and only when it clicks anywhere on the screen except a UI button? Right now, I have an OnClick() event that shoots the gun, but the gun still shoots even if it was a UI button that was clicked.

cosmic rain
hushed laurel
#

Seems like a design oversight

cosmic rain

There might be cases where you want to click through the UI. And it's not even clear what you want to consider ui or not. Too many factors to consider that prevent making it a standard feature.

That's impossible

hushed laurel
#

I feel like what I'm asking for is an extremely basic feature though

#

I know how to get around it being missing of course, but I just didn't expect it to actually be missing

cosmic rain
#

It's not. But there are tools in unity to do that. It's just that you need to write some code to make use of it. As I mentioned in the first message.

cosmic rain
#

There's just to many factors.
Besides, you would usually have a sort of UI manager in any project.

#

I also don't think there are many engines with that feature.

#

Maybe some very specific narrow engines have.

This would return true on non ui objects too if physics raycaster is used afaik.

NaughtyAttributes is fantastic

hard estuary
#

@whole sorrel Btw, have you considered moving this from ScriptableObject to some sort of GameManager? ScriptableObjects are made mostly with persistent data in mind. They can be used to also store runtime data, but it might create some unexpected confusions (like the one where you tried to serialize a reference to a component inside of a scene).

Is there any specific reason why VS Code is not finding the namespace even though the package is installed?

I think using ScriptableObjects for runtime data could be handy for save data if someone wants to be able create asset presets and possibility of creating save files in runtime, that way both features could share the code.

I need to spawn a mesh that would be present in front of the player all the time ?
Would you do the spawning in Awake() or Start() ?
Like as a general rule, spawning things at the start would be done in Awake() or Start() ? Are there bugs that could happen if it was done in Awake() for instance ?

hard estuary
# fiery steeple I need to spawn a mesh that would be present in front of the player all the time...

Awake is called before Start. Start is called on the frame the script is enabled for the first time. Technically you can spawn a prefab with disabled scripts and Start won't run until you enable them. Another difference is that Awake is called as soon the script's instance is created, meaning you can't do much beforehand. Example:

void SpawnPlayer ()
{
  var player = GameObject.Instantiate(playerTemplate) as Player; // Awake will be called
  // Here you can do something before Start is being called
  // Start will be eventually called later
}
steady bobcat
#

as Player huh

fiery steeple
#

And the spawning is on a script that's on the player himself

hard estuary
# steady bobcat ``as Player`` huh

Can be useful if for any reason we're instantiating something with a generic reference. Rather rare occurrence. Most times it's better to use more specific references.

steady bobcat
#

just seems out of place in such an example. Also always prefer (T)v casts over as.

hard estuary
# fiery steeple And the spawning is on a script that's on the player himself

Then if you spawn Player and you spawn mesh in the Start method, the mesh won't be spawned if the player had its mesh-spawning script disabled. It's something rarely will happen, but you wanted a potential issues, so I listed this one. I usually spawn disabled objects when I'm optimizing UI, but it's a more advanced topic.

fiery steeple

steady bobcat

er what

fiery steeple
steady bobcat

hexed pecan
#

At some point, the object you want to preview could have more than 1 mesh too

fiery steeple
hexed pecan
#

So it might make sense to draw the preview object with one of the DrawMesh/Rendermesh methods

hexed pecan
#

So recycling a single meshfilter+meshrenderer for the preview would not be enough

hard estuary
# fiery steeple so where do I put it then ?

In 99% of cases it doesn't matter. In the other 1% cases you either want to do it in Awake (during the initialization, to make sure it's always spawned at the same time the player is being spawned) or in Start (to delay the object spawning until you actually need it). If you prefer reliability over optimization, pick Awake. If you want to make things more optimized and you know what are you doing, pick Start.

hey so I'm making something RTS/tower defency. I want to be able to research techs that boost stats of units, think HP + 10% etc. etc. I want a flexible system to be able to apply these buffs/debuffs to all units in an easy and performant way. Happy to go for an asset that does it for me 😛

It would be nice if the same system could also be used to apply temporary buffs/debuffs during gameplay also.

I was reading something about factory pattern scriptable objects, is that like a universally agreed upon route?

hard estuary

# fiery steeple And is Update() called after Start() ?

Yes. You can test it out by adding Debug.Log (Time.fameCount); to your methods - logs displayed in the console will appear in the same order methods were called, and you will also get information about the current frame number.

When it comes to removable buffs (including temporary ones), I would recommend always storing them as a list of buffs rather than modifying the actual value. I think ScriptableObjects are great for making up presets, e.g. you could create a preset for different buffs (constant values and percentage values), then store them in a list and use ScriptableObjects method to calculate the new value. It would be very flexible solution, but the downside would be bad optimization if you have dozens of buffs applied at once.

hard estuary
crisp flower
#

Thanks. " bad optimization if you have dozens of buffs applied at once." so this is something I'm concerned about. not only is it on android it's mobile VR, with potentially hundreds of units.... So the idea of having load of scripts and objects calculating stuff all the time is a bit scary vs. something ike keeping a database of values or something and just loading them all in on start/spawn (obvs wouldn't work for temporary effects). That said I'm GPU bound vs CPU so... And maybe there'd be eg. 3 techs for ++ health, 3 techs for ++ accuracy etc etc and can imagine them all piling up

does unity have some build-in methods for sanitizing filenames?

crisp flower
# hard estuary An optional solution would be to cache your stats every time a buff is applied/r...

do you think on a per unit level? So... in my game, there would be research that you can unlock outside of the tactical level, which wouldn't be recomputed during the tactical (gameplay) level. I was wondering if calculating the stacks of buffs at the beginning into some kinda manager, and then when units are spawned they query the manager... something like that.... although then I suppose that would lead to there needing ot be a separate system for temprary status effects etc etc etc

hard estuary
# crisp flower do you think on a per unit level? So... in my game, there would be research that...

If some bonuses are being applied outside of the game, then it would make sense to process them beforehand. But it might not work if your system has to be extremely flexible, for example, if you have +5 attack buff and +100% attack buff, then you can't "merge" these buffs without knowing the base stats of an unit. And even if you knew the base stats, then things could be complicated once a new buff is applied. Imagine that you want % buffs to be applied last, that way cached value would need to be split into constant bonus and % bonus. If you get a buff like "+1 attack per 10% of health lost", then you would need to recalculate this value every time health of your unit is changed. In conclusion, precomputed bonuses will work fine, but only if your stat system is relatively simple.

Pretty much replace those Vector3.down/left with -camera.transform.up and -camera.transform.right

transform.up/right/forward are in world space, but relative to the transform

For some reason the raycast doesn't detect my shelf

#

First take out the layer restriction, if it works after that the layers are wrong. If it still doesn't work, take out the distance restriction and if it works after that, the distance is too short. If it still doesn't work the object doesn't have a collider

fiery steeple

#

Note that layer and layermask are different things

fiery steeple
#

The distance I set it to 10 so I'm kinda confused on why it doesn't work knowing that 10 = 10 meters and the ray in the Scene Preview the ray looks long enough to intersect with the shelf

fiery steeple
mellow sigil
#

If it works without the layer restriction then obviously there's nothing wrong with the distance

You can just declare a LayerMask instead of an int layer and use that

Save data should be handled with DTO object. With some JSON library, you can embeded the type of the given object in the save if you need.

Alternatively, you can serialized in two step.

{
    "WorldState": [
        "id": "..."
        "data": "Other Json"
    ]
}
hard estuary
#

You can create automated class serialization with JsonUtility:
https://docs.unity3d.com/6000.0/Documentation/ScriptReference/JsonUtility.html
Keep in mind that automated serialization might try to serialize things you don't want to serialize. In the end, it's better to do things manually
Here is a Unity package that adds some JsonConverters that improves serialization for Unity classes:
https://github.com/applejag/Newtonsoft.Json-for-Unity.Converters
And here is an example of Vector3 converter:
https://github.com/applejag/Newtonsoft.Json-for-Unity.Converters/blob/master/Packages/Newtonsoft.Json-for-Unity.Converters/UnityConverters/Math/Vector3Converter.cs

steady moat
#

The idea behind using a DTO is to separate data that are not serializable from data that are.

#

can someone help me? when i double click on a script in my game and im wanting to edit it why does it ask media player or notepad

steady moat
#

You could have the following.

[System.Serializable]
class EnemySave
{
     public string ID;
     public string Data;
}
#

Obviously, it would assume that each enemies are already known in advance.

You can delay the deserialization to whenever you know the type. By example, in case of a door, the door could look to see if there is a save with the given ID. From there, you know what the serialization type is.

Also, you might want to use polymorphism with your class, you can with Json. Alternatively, you save multiple object, one per class parent.

hi there, i'm encountering an issue when loading a scene a second time during the execution of my game.
game objects are keeping old references to their children gameobject in serialize fields which result in a MissingReferenceException.
do you have a any idea how to deal with this behavior? i was expecting that my object will instiante his children and refresh his serialize fields

thanks!

somber nacelle
#

sounds like you may have a DDOL object that either shouldn't be DDOL, is doing too much and wouldn't need those references, or you need to update the references to those objects when the scene is loaded again so you are referring to the new, existing ones

Hello. I am having some trouble getting foot IK right. I can't find a way to set the target for the IK right after the animation frame. I don't think I have a full grasp on what happends when. I found a post theorizing that the animation update happends before the component lateupdate, but then I would think that this would work. Anybody that sees my mistake? (don't mind the foot normals)


    public Transform left_ray_from;
    public Transform left_ray_to;
    public Transform right_ray_from;
    public Transform right_ray_to;
    public Transform left_target;
    public Transform right_target;
    public float raycastDistance = 3f;
    public LayerMask cameraWallLayer;

    void LateUpdate()
    {
        AdjustFootTarget(left_ray_from, (left_ray_to.position - left_ray_from.position).normalized, left_target);
        AdjustFootTarget(right_ray_from, (right_ray_to.position - right_ray_from.position).normalized, right_target);

        // AdjustFootTargetVertical(left_ray_from, left_target);
        // AdjustFootTargetVertical(right_ray_from, right_target);
    }

    void AdjustFootTarget(Transform rayOrigin, Vector3 direction, Transform footTarget)
    {
        if (Physics.Raycast(rayOrigin.position, direction, out RaycastHit hit, raycastDistance, cameraWallLayer))
        {
            footTarget.GetComponent<TwoBoneIKConstraint>().weight = 1;
            footTarget.position = hit.point;
            footTarget.up = hit.normal;
        }
        else
        {
            footTarget.GetComponent<TwoBoneIKConstraint>().weight = 0;

i was kinda thinking about it before i asked my question but it also has its own issues but it is much more reliable because if players will get throught the triggers wall in an unexpected way then... i need to monitor those triggers all the time if anything changes in the world

Hi everyone, I'm playing around with loading and unloading scenes asynchronously using the SceneManager.LoadSceneAsync, and come across a bit of a problem.

I have a manager scene that controls which scenes to load additively and then which to remove. Ideally I would like the behaviour of seemlessly switching between the two scenes. This could be fine, however their is a chance that the scene can swap into instelf.

Since the Loading of scenes taxes either their path or the build index, this means their is no way to destinguish which scene I want to load and unload from the copies? How would I do this?

(Specifically, I have 2 versions of the same scene loaded, I want to unload 1 which is the older version, how would I go about removing specifically this one).

simple ridge
#

I have found that UnloaScenedAsync can take a scene itself as an arguement this solves half the issue, now the problem would be to get the loaded scene from the LoadSceneAsync function

rigid island
#

to get the scenes

simple ridge
#

These will return the same name would they not? If I have two scenes with the same name I cannot differentiate between them

rigid island
#

curious, why do they have the same name?

#

also aren't the index different anyway

simple ridge
#

The project is an example project for a class where they are making a WarioWare like game, once the "microgame" is completed it then calls another from the collection. This means their is a chance that it can call the same game again to play.

Meaning that I am then unloading scene "mini-game A" and loading "mini-game A" again, which causes a problem as then Unity gets confused between which scene I mean to be loading and which I mean to be unloading.

#

So I would need to use a way of differentiating scenes in runtime, without using the scene build index or its name

#

I do recognise that this "can be solved" by just not allowing the same mini-game to be played twice, however that isn't the purpose of this excercise and I would rather have the functionality to reload the same scene then locking myself out of it.

#

Is their a way to find the most recent scene, and then rename it?

somber nacelle
#

why not load into a load scene, unload the old scene, then load the new one? that way you can never end up with collisions like that

simple ridge
#

The scenes are meant to be very quick, so mini-games in around 5 - 10 seconds, so having loading scenes would be a bit much. Ideally I would load the "next" minigame while the current one is being played.

#

Then activate it once the current minigame is complete

#

This is the kind of thing I am trying to accomplish

#

The students would each work on their own scene, and then at the end given they add a call for Success or Failure, the minigame manager should automatically transition between the minigames.

#

But to do so, they need to be ready and waiting to be swapped in.

rigid island
simple ridge
#

xD

rigid island
simple ridge
#

Some of them, but others no

#

Some just trainsition imidiatly into the next mini-game

#

Though that said, the minigames dont repeat, so they arn't facing the same issue (not that I know if WarioWare was made in Unity or not or some bespoke engine)

#

But does what I need it for make sense now?

rigid island
#

I still assume SceneManager.GetSceneAt could get you the latest scene and pass that Scene object to the Unload

simple ridge
#

Is it always garanteed that the most recently loaded scene would be the final scene?

rigid island
#

tbh I havent messed with this too much though so take it with a grain of sault

simple ridge
#

If so then that would work perfectly

rigid island
#

you could test it

#

with a loop or something

simple ridge
#

Ah okay, well Ill give that a shot for now, and see how it works. It may work wonders!

#

Yeah

#

Thanks!

#

Ill give this a go now then ^-^

feral mango
# turbid pagoda If I have a cylinder, how could I find the point that has the lowest Y axis and ...

Not sure what you mean with the top edge, but I have an idea how you could solve it, it's probably not the best. So your cylinder is defined by certain rotation, which is a certain direction. This direction is the normal of the top circle. That normal and the middle point of the top circle define a plane. Also the y-axis and that normal define a plane. The intersection of those 2 planes forms a line, the intersection of that line and the circle gives you 2 points. The highest and the lowest, take the lowest

#

There is probably a simpler way, also depening on how your cylinders are defined.

guys is it a good way to code a ability system for a roguelike where alle the skills are 0 at the start and if he like choses a specific skill in the popup the skill index is 1 so the program knows that this skill is active since its not 0 or is there a better way to handle skills for a roguelike. Like how should i do a skill system ? thts the only plan i had

trim schooner
#

If you're just using 0/1 for active or not, you may as well use a bool.
If the value can increase higher than 1 with levelling up, then sure, use 0 as inactive state.

craggy veldt
#

sometimes, it makes sense representing 0 - 1 as false/true state
mainly for branchless stuff

west drum

yeah it can increase so is it a good way you would say?

so i thought it might be a good way to make the number increasable

well, if it's value types you're bound to boxing (due to object to T casting)

#

even if they're ref types, you must cast them whenever you want to get something from it

#

that said, no reason to use ArrayList at all unless for legacy reasons (supporting old apps)

#

also you can do this with arraylist

arrayList[0] = "something";
arrayList[1] = 1;
arrayList[2] = `c`;

that's just super bad

#

plucky inlet
#

Hello there, I am using awaitables right now and wondering, how to prevent it to be in a detached state. Simple example calling this from a delegate in another script will fire, that joiningTask is in a detached state. I am sure, its a simple fix but I was expecting the completed check to be enough to avoid it.

private async void JoinVivoxChannel(string userId, string channelName = "DefaultChannel")
        {
            if (joiningTask != null && !joiningTask.IsCompleted)
                joiningTask.Cancel();

            joiningTask = JoinVivoxChannelAsync(userId, channelName);
            await joiningTask;
        }
#

Or do I also have to work around the cancellation with a token?

#

There is also some example code in the docs to wrap it in a task, which would lead to token usage. But maybe there is some way for awaitables to do on their own?

thick terrace
#

not sure without being able to debug it but this might have something to do with Awaitables being pooled objects, i'm not sure it's safe to keep a reference to one after it's been completed because it could be reused for something unrelated

#

a cancellation token should solve it in that case yeah

at minimum even in FixedUpdate I would add Time.deltaTime in the horizontal eval

#

let me try the pivot point, out of curosity, what would that math look like for adjusting position?

slender bear
#

Yeah I’d think ray cast down as you change size to check where the ground is so you can correct the position.

#

But also just making the pivot at the bottom might make that unnecessary

rigid island
#

ya like everything in any solution there are pros and cons of each

#

the latter (position adjust) requires a bit of math
account for the bottom half from the center point and use something like ray to find the ground etc

slender bear
#

Yeah if just making the pivot at the bottom does it then I’d just stick with that

wide totem
#

for changing the pivot, i have to make it a child of a 'pivot' object right?

rigid island
#

but ideally you always want your grafix separate from your parent

Only thing is that might mess with other code that’s checking position

Those are different things. It's recommended to use the one you need

It's like comparing a wheel and a car

#

Transform is part of the gameobject

#

It's just another component, but it's special in the way that a gameobject always has a transform

fiery steeple
#

Yeah I know that but here I'm more talking in terms of recommendation of which one to use because alot of the times I do this :

  • When I use a Transform, sometimes I have to do this transform.gameObject
  • When I use a GameObject, sometimes I have to do this gameObject.transform

if it doesn't have any other components i generally use a [SerializeField] Transform

I skim through things and I understand their context

fiery steeple
#

Damn I wish I have a brain wired for 1x5 like you guys 🤣

rigid island
#

so usually I stick to transform when there is no components, and if you have a component use that eg [SerializeField] MyFancyScript

#

since all components can access both gameobject they're on and their transform

fiery steeple
#

Oh because if there are other components you will have to do something like this : transform.gameObject.GetComponent<T>().blabla instead of just gameObject.GetComponent<T>().blabla?

rigid island

You can get component from ANY component

that includes Transform

transform.GetComponent<T>().blabla

But gameObject doesn’t derive from Component does it? I actually don’t know

rigid island
#

GameObject is also a component

hexed pecan
#

It's not

#

It's UnityEngine.Object

rigid island
#

oh right its the root , brain aint brain today 🚶‍♂️

hexed pecan
#

Which is also the root class for scriptableobjects, components etc

fiery steeple

Someone made this statement, what do you think :

*The two types have two jobs. They have direct links to each other, but use the type that makes sense for what you're doing. If your primary need is about position or parent/child relationships, Transform makes sense. If your primary need is instantiation or activation or dealing with the object as a whole, GameObject makes sense.

And if your script really is only interested in a particular component like a CharacterController or something, use that type reference instead of either of the others.*

slender bear
#

That I think sums it up well

rigid island
#

reasonable

hexed pecan
#

That's again pretty much what we been saying

slender bear
rigid island
hexed pecan
#

AddComponent is for gameObject only. Maybe you are thinking of that

slender bear
hexed pecan
rigid island
#

seems reasonable yeah since thats the "container" of all components

#

I love how they say

ScriptableObject as a way to create scripts that do not attach to any GameObject.
poor Poco

slender bear
#

But yeah if you just keep “Don’t repeat yourself” in mind then reading your code will tell you whether you’re using the optimal type reference

Do we agree that declared variables inside methods (here Update), the next time that method is called it doesn't save the previous values in those variables anymore ?

#

Well, that. Finding the lowest point on the top face edge of a cylinder

feral mango
#

what is the further purpose of it?

#

if it's a cilindrical mesh and you need a vertex, I might suggest looping through the vertices and finding the one that you need

turbid pagoda
#

The point where a liquid would pour out of from a cylindrical container (ie. a cup)

turbid pagoda
feral mango
#

that's a bit tricky depending on the cilinder, but you could probably set a condition to find all top ones: vertices who are in the radius of the top circle. then you take the lowest one

#

or maybe you could define some points yourself? add them to the mesh, then take the lowest one

turbid pagoda
#

Yeah but then you cant get a exact point unless I made a lot of points

feral mango
#

@turbid pagoda if you want an arbitrary point I would suggest doing something like this:

image.png
#

calc the blue point

#

you can do it with the normal, and it has to be in the same plane as the y axis

#

and perpendicular to the normal of the cilinder

#

or actually, you just mirror the normal around the xz plane, then you scale it by the radius of your top circle and you should have it

my game currently involves lil robot guys that travel through space towards scrap which it then brings back to a storage object. Ive currently been doing this using just the lookAt feature then basically ramming the object forwards in the hopes it hits it, which worked well enough, but i kinda need it to not hit things on the way, which means i need pathfinding, which means nav mesh, but i dont have any clue how to get it to work on open space, or if it even does work

#

as you can see my lil green guys arent very good at reaching what theyre meant to due to terrible overshooting and lack of pathfinding from my current method

Need some help with a package I’ve made: It contains both runtime and editor components, AND uses OTHER packages I’ve made, so I created two assembly definition files, one for editor, and one for runtime. The editor asmdef is shown in the image below. In the unity project where I have this package defined, everything compiles without problem.
Problem: When I import the package into another project, I get the following compiler error:
Library\PackageCache\com.glurth.memberexposer@d01f2037f9\Editor\DataTypeToDisplayPrefabMappingEditor.cs(133,30): error CS0115: 'DataTypeToDisplayPrefabMappingEditor.SaveChanges()': no suitable method found to override
Which makes no sense because this class derives from the UnityEditor.Editor class,which DOES indeed have this override-able function:
https://docs.unity3d.com/6000.0/Documentation/ScriptReference/Editor.SaveChanges.html
Here is the class declaration.

    public class DataTypeToDisplayPrefabMappingEditor : UnityEditor.Editor```.

I SUSPECT it has to do with the asmdef, and resolving UnityEditor

Yooo, I got a problem with rigidbody2D which it doesn't detect collisions.
This is in Unity 2D and I have my character that jumps and I want to make him fly if I press "p" , making him "kinematic".

#

and to make him not fly I want to press "p" again while flying to cancel it but when I do that the collision doesn't work

I belive rigidbodies have an option for if they use gravity or not. suspectTHATis what you want to set instead. @night nebula lemme see ifI can find it.

kinematic ignores collisions when you move it

you should configure your IDE.
Rigidbody2D doesnt have a useGravity bool

OnCollisionEnter is not for 2D

the signature is wrong for that 3D one and it should say so in IDE

# fiery steeple Anyone please ? 🙂 ☝️

I'm not sure, looking at the code I dont see anything obvious, but I could just be missing it. Suggest adding lots of Debug.Log stuff. log the NAME of the raycast hit object, log the name of the objects in the placement list, log the layers of each' etc... This will help narrow down the issue- you'll be able to see at a glance it the raycast check is passing somthing unexpected.

tall scroll
#

so when you add the transforms to the list, try checking if the transform it's looped on is itself and if so continue

#

and instead of making it nullable personally I'd allow it to return an empty list and just see if it's empty instead of null, might just be preference though

mossy snow
#

no, that method is poorly named because it gets components on self and all children instead of just children like the name seems to imply

tall scroll
#

although I am now looking at that function and seeing another error

#

you check obj.transform.childcount but when you loop you loop on transform, should that instead be looping on obj.transform?

# fiery steeple you're the boss https://gyazo.com/dc77ae881e42cd2bd81b02ccb4193499.mp4 , Thanks ...

you're trying to loop over the children of a transform of a specific object, so you've done the right thing in specifying obj as a parameter. A couple lines later you then accurately check the child count of that object using obj.transform, which is the transform for that specific object. However, a few lines later you iterate over transform. transform is a transform so it's not going to cause an error, but it will be the transform of the object that monobehaviour is attached to, which is likely the player. By specifying obj.transform you change it to specifying the transform of that other object 🙂

I guess here ?

Hi there, I'm making a button remapping system for my uni project. I just want someone to tell me if my way of doing this is stupid and that there is a better way or that my way is okay. I don't trust my team to not randomly add new buttons so I'm making the buttons on the fly from the input actions script.

I'm making a button that gets added to a list for every item in the input actions asset that meets certain criteria to show up. And each button has a class on it that stores the button object itself, the InputActionReference and a sub reference for things such as WASD to make multiple buttons from the same action reference or if there are multiple buttons for the same thing.

Haven't done much else yet like actually changing the key binds but I want a sanity check as I've been doing ui stuff seemingly non stop for the past few days minus a 4 hour drive and sleep and what not. I'm just slow at getting work done

# civic folio Hi there, I'm making a button remapping system for my uni project. I just want s...

Games often have some restrictions regarding to the controls menu, such as removing the "change binding" input from the list or locking inputs related to UI navigation. It might be wise for some games to create each option manually. In the end you'll probably want to localize these inputs anyway. Automating the process can be helpful, but it's worth remembering that you may encounter cases where you would want to modify some entries yourself.

civic folio
#

hmm, makes sense. I can't lie I'm just struggling to get my head around the button rebinding stuff for some reason. I feel like I'm throwing stuff at the wall with little to no feedback on if what I'm doing is right or not because I wont be able to see if it works until its done

#

everything else I've done on this project I've had some small little progress bits here and there which makes me feel like I'm actually doing something. But this just isn't

#

its annoying

kind nymph
#

so right now I have to ensure only one of these components exists at a time in any given scene, and the way I'm thinking of doing that is giving the class a static 'instance' variable that's set in the Awake() method and will never set it if it's already been set. This exists so other scripts can get the instance of the script without having to do GetComponent<>(). My main worry is if this causes a circular dependency or not, to my knowledge it shouldn't be since the field is marked as static so it exists globally and not per-instance (which is what i want anyway) but I just wanted to check in case im being paranoid or if there's a better way to go about this

image.png
somber nacelle
#

what you've described is the typical way to implement the Singleton pattern in unity so it is perfectly fine. Just make sure to set the instance in Awake (and do your destruction of extras there too) and never access it before Start. i'd also recommend making that a property rather than a field just so you can make the setter private

#

also there is nothing wrong with a "circular dependency" in this context or most contexts since nothing bad will happen if an object references itself. usually the only issue with something like that would be with serialization but that's not going to be relevant here anyway

kind nymph
night harness
somber nacelle
#

what do you mean by "grab it in the getter"? as in assign to instance in the property's getter? because if so, that would require it to instantiate a copy manually in that code or use a terrible Find method, the first may not be ideal if they want to do any inspector setup, and the second is just unnecessarily slow.
So while yes, that would solve execution order issues it may not be ideal depending on their needs

uhhh, sup everyone, i am not really sure this should go here, but i have a somewhat design / math question?
Basically i have a list of rarities with 100% total, each rarity having their own percentage.
Inside those rarities there are objects with "weights" which are not %. When i pick an object i sum all the weights, do random and flip through the list to find the needed object.

Basically, i was wondering if it would work the same in terms of chance if i made a single list of objects and just made the weight like

int weight = Mathf.RoundToInt(rarityPercent * itemWeight / 100);

lean sail
dry yarrow
#

and i have a spawner object, which is a pain to operate with a bajillion different lists, tons of foreach loops and stuff like that, that in the inspector sets itself the correct mobs he can spawn through flag correlation.
and so i'm trying to optimize all this

lean sail
#

I think I can see what you were trying with that formula if you're summing up every single rarity in one list

dry yarrow
#

yeah, since its like rairty is a percent from 1 to 100

#

its just weighing percents

#

for each item

#

no?

lean sail
#

I'm not sure if you know what I'm asking you

dry yarrow
#

i am honestly confused by now

sick cove
#

i'm trying to access a self made script from a script which was included in a package in which i'm editing a method to change a bool in my own script. however for some reason i can't access my own script except from my own other scripts. I can access the scripts form the package through my own scripts, usually when using namespaces.

the package is 'code monkey toolkit' None of the scripts are accessible through newly created scripts. other way around works normally.

dry yarrow
#

but since its a spawner and it has 5 different lists, it feels very unnatural, clunky and very uneasy to use, so i'm trying to see if modifying the weight of the item with the rarity percent will produce the same random chance result

lean sail
dry yarrow
#

cause it feels right and wrong at the same time?

#

A #if UNITY_EDITOR method i devised:
0) Create a single availableItems list

  1. For each rarity in library we take each mob that has the required flags
  2. buffer the modifiedWeight with formula
  3. Put the mob in the single list, replace his weight inside the rarity with the modified list

This way i achieve a single list weight check without a bunch of checking rarity, then going into the rarity, checking every item for flags, summing needed weights, getting random index, returning to library and grabbing the item

lean sail
dry yarrow

sick cove

hello, i'm trying to make some panels on the sides of the screen that make your camera rotate (im making a stationary character), but every time i point over one of the panels it detects the left side one and rotates counter clockwise. I've made sure to have separate rotations for each of them and with a little debugging, i found that no matter which panel i hover on, it only detects the left one. I'm using ispointerovergameobject

lean sail
# dry yarrow pain in the ass how? 🤔 Like, to navigate you mean since its gonna be an undivi...

Im honestly not fully following what you intend to do, but the current setup you have is the most clear for developers to see in inspector and actually understand. Editing it would likely also be easier.
If you're going to just take the existing separate lists and combine it into a big list through code at runtime, then theres just no point in doing this. You already have it working in a clear way, having it work with a different formula and expecting the same result doesnt solve anything new

#

Plus it's also just more performant to not do that

dry yarrow
#

So im trying to get a smaller list in the spawner in editor that will allow me to lighten up the calculations on runtime

night harness
#

I'm not judging or anything but how accurate is that 1000 number because i feel like i've never seen any game have 100 entities share 1 spawn pool let alone 1000

dry yarrow
lean sail
#

How you described your current setup in the initial message is literally how you should do this.

dry yarrow
#

and adding only those to the spawner list

#

so it won't have to go through the whole library on runtime

night harness
#

you should just have some sort of spawn list scriptableobject that is given to the spawners

#

and filter them yourself?

lean sail
#

I feel like this whole "going through the whole library on runtime" thing was just randomly brought into context. The first message implied your spawners already had lists of what they could spawn

dry yarrow
lean sail
#

This seems like a separate problem from what you were first asking. In which case yea i think scriptable objects would be fine here to define a list that each spawner could use

dry yarrow
#

yeah, that's... exactly what im trying to do but the question is not in how i should do it, its in the math

#

will a weight modified by a %, result in the same chance than a separate check for them

night harness
#

the issue is your avoiding loops for assumed optimisation problems when ideal data handling should not create lists big enough to come close to being problematic

lean sail
#

I think you're really jumping all over the place here. The way you described you're doing the math in the first place is how you do it.

lean sail
#

Let them choose a rarity and only have objects of that rarity type

dry yarrow
#

i feel like im really just going insane by now ngl

night harness
#

could you give an example of those flags

dry yarrow
#

This is the structure of the main library: its a list of rarities, that have %, enum to navigate and the SO with items of said rarity

image.png
#

the item SO that has all the items

image.png
#

(and the flags)

lean sail
# dry yarrow i feel like im really just going insane by now ngl

Ok let's take a complete step back and I'll answer 2 things directly. First, the problem of these flags weren't well described but no matter what you do, at the end, each spawner should have lists of what they could spawn. Each small list is associated with a rarity
Now about the formula: a weighted random formula does not care what the scale of the numbers you use is. If you have weights of 1, 1, 1 it's the same as having weights of 2 2 2. But your initial formula doesnt guarantee a direct conversion because it uses percents and rounds to int. And the formula would imply you're putting everything in a big list for the spawner rather than multiple lists which is worse in terms of performance even.

dry yarrow
#

and if the editor will stop freezing at compilating scripts, i'll gladly show you the spawner preset-

#

and this is the preset

image.png
#

so the bugs have flags on which they can spawn, so does the spawner preset

dry yarrow
lean sail
#

Well I'd definitely try not to hardcode it like that, maybe have a class that stores an enum for the rarity and then list<bug>. Then you could make a list of this new class

dry yarrow
#

i mean, yeah lmao, this is just a very shitty example

lean sail
#

Or you could have a dictionary, but they arent serializable by default so youd need to look online for an implementation of that

dry yarrow
lean sail
#

If you're just searching for the list by its rarity, a dictionary makes more sense. Either way it could be in an SO

#

Still list of lists, or dictionary with <enum, list> is still better than 1 big list

dry yarrow
#

ok, got it

#

thank you i feel dumb 😭

#

i've been thwacking my head at the game design behind all this for past two days with a 3 dimensional system with time & weather conditions and rarities and when it came to code i guess i'm just completely exhausted and braindead

lean sail
#

This is also a pretty common thing for games where they will roll a rarity and then roll the actual item. Or they separate items into "tables" if rarity doesnt apply

lean sail
night harness
# dry yarrow the item SO that has all the items

One kind of thing that you don't have to act on at all and just might be worth thinking about is a lot of these spawn conditions could be defined just be the context of what the spawner is and/or where it is

#

eg. you don't necessarily need to know that a butterfly can't spawn at a river if you just don't ever have butterflies in a river spawn pool

dry yarrow
#

i mean, yeah, but its just more things to do by hand and i want it to eco my time in the future rather than doing every spawn list for every spawner by hand and all that... seems like a tech artists' hell

night harness
#

👍

dry yarrow
#

this way i just slap a preset, press a button and whapow it has all the right bugs

#

so yeah

Hey, I made a gameobject with a script and the Update method only run once at the start, any idea why? Here's the script:

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

[RequireComponent(typeof(Animator))]
public class FadeAnimationScript : MonoBehaviour
{
    [SerializeField] Animator animator;
    [SerializeField] CanvasGroup group;

    void Start(){

    }

    void Update(){
        Debug.Log("Script running");
        if (animator.GetCurrentAnimatorStateInfo(0).IsName("FadeOut"))
        {
            Debug.Log("Fade Out");
            if(group.alpha == 0) gameObject.SetActive(false);
        }
        else if (animator.GetCurrentAnimatorStateInfo(0).IsName("Idle"))
        {
            Debug.Log("Idle");
            if(group.alpha != 1){
                group.alpha = 1;
            }
        }
        else if (animator.GetCurrentAnimatorStateInfo(0).IsName("FadeIn"))
        {
            group.alpha = 1;
            Debug.Log("Fade In");
        }
    }
}

And here's what the inspector looks like:

image.png
#

I onky get "Script running" once in the console

#

And the GameObject is still active

#

Script too

tiny pendant
mossy oyster
#

Yeah sure

#

It also looks like there's some problem because resizing the game's window when in play mode doesn't update canvas element's positions unless I update something in the inspector

#

(switching off a component or switching the GameObject to inactive and then putting it back)

#

Wait no that's not the only problem

#

The game only run the first frame

#

It worked just fine yesterday

tiny pendant
mossy oyster
#

Update loops just don't run

#

For some reasons

tiny pendant
#

only thing i can think of is something is disable it right after it's run once
or it run once then stopped/ disabled it self

mossy oyster
tiny pendant
#

if(group.alpha == 0) gameObject.SetActive(false);

#

this one

#

this one causing the problem

mossy oyster
#

No it's not

tiny pendant
# 
 using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using UnityEngine.UI;

[RequireComponent(typeof(Animator))]
public class FadeAnimationScript : MonoBehaviour
{
    [SerializeField] Animator animator;
    [SerializeField] CanvasGroup group;

    void Start(){

    }

    void Update(){
        Debug.Log("Script running");
        if (animator.GetCurrentAnimatorStateInfo(0).IsName("FadeOut"))
        {
            Debug.Log("Fade Out");
            if(group.alpha == 0) //gameObject.SetActive(false);
        }
        else if (animator.GetCurrentAnimatorStateInfo(0).IsName("Idle"))
        {
            Debug.Log("Idle");
            if(group.alpha != 1){
                group.alpha = 1;
            }
        }
        else if (animator.GetCurrentAnimatorStateInfo(0).IsName("FadeIn"))
        {
            group.alpha = 1;
            Debug.Log("Fade In");
        }
    }
}

try this again the update should running and not stopping

mossy oyster
#

GameObject is still active + it's not running FadeOut animation at the start, it only run it when I click some buttons but those buttons just won't appear as they don't fade in at the start

ok anyways back to the issue

vestal arch
# mossy oyster

from this, make sure you have saved, recompiled, added the script to an active gameobject in the scene before hitting play

mossy oyster
#

I did

#

It only appears once in the log

#

Update() is called only once

vestal arch
#

ok so it does work

mossy oyster
#

And that's the same for every script

vestal arch
#

you have error pause on

the error is causing the game to pause

mossy oyster

Oh god

#

I'm dumb

#

I missclicked on that

#

Thanks a lot

it's more hard to know what actually cause it

hey, im trying to get unity for 3ds to work, it builds okay and i have a basic scene with some testing text, but when i run it on hardware or in citra it just crashes after a second or two.. any common issues i can check for?

#

sorry i know this is quite a niche unity build

#

is there a specific community for 3ds development? if anyone knows please share :)

Usually the game crashes when an endless loop occurs, because app is not responding or it runs out of resources. Endless loop usually happen when:
a) the exit condition of one of yours for or while loop never is fulfilled
b) one or more methods invoke each other
You can also try to narrow the problem down by checking out the game's log files:

Hello! not sure if this is the best channel for this, please let me know if I should go to beginner or advanced. this is my first time in this server!

anywho: I would really appreciate if i could get some help on this part of my project. I was following a tutorial which I will link here: https://www.youtube.com/watch?v=fApXEL0xsx4 I understand tutorials aren't the best way to learn, however this video uses the old input system and i wish to use the new system. so there is already a challenge for me to figure out. However I cannot replicate what is done in the video. I took 2 solid attempts at it, and the first time: my mesh was getting stretched when I picked it up. and the next time I tried it, it shot up into the air, and since the script disables gravity, it stays off for some reason and keeps flying upward lol. and after trying to fix that, it just kind of just jitters. I'll send a clip if I can.

The creator of the video kindly offered to help me, but YouTube understandably flagged my comment containing my code(but other comments have their code so its also odd). but YouTube seems to have shadow banned me from the channel for that. and I can no longer get in contact. They even removed my original comment:(

My goal at this point is to just get it to work with the old system before I even try adding the new system to it. which may be a strange approach but I don't really know a lot about what I'm doing. I feel like I have an understanding for some parts. but others I really just need the helping hand for. Which I understand, this is tricky to do alone. Any help is greatly appreciated. I have also provided my code here: https://paste.mod.gg/hkeredlddbpf/1

I have attempted other guides too, no luck, and at the end of the day: I really want to use this system, It appeals to me the most. So I would love to make this or something just like it functional.

Thank you all so much in advance! this means so much to me finding this community here. I felt so doomed lol!

guys what's the best way in terms of organization and practicality for autosaving a big amount of player data?

#

Multiple characters will be playable so I'll have general data that covers the whole save file and specific data for each character

Separating it into small pieces that are useful individually. E.g. instead of saving data about all characters in one place you can separate it, so you can save and load only data of characters that were selected to use. If the amount of total data is huge (e.g., multiplayer games with thousands of accounts) it's worth using a system that is optimized for it (e.g., databases). Keep in mind, that splitting data into too many files might backfire - there is an overhead for each file, such as checking access privileges.

It doesn't sound like a huge amount of data. For me small amount of data would take less than 200KB, a medium one up to 1MB, a big one up to 10 MB. The Android limit for save files is 3MB. Assuming you won't have a lot of missions and other types of data, then you will probably fit below 500KB. I wouldn't worry about it much unless you very often autosave the game or you keep a lot of saves at once. 1KB is 1K characters, so you can estimate how much data it will take. Technically you can optimize saves by creating your own binary serializer/deserializer, but it takes effort to update. Using Json format will be more comfortable (it's easier to automate, it's easy to read and edit, and it's less vulnerable to changes in code).

Btw, it's worth to mention that the most issues with save files relate to the version compatibility (e.g. when you add something new to the game, your old save files won't contain information about it). When adding new content, you should assume that your old save files may lack some information or have redundant information.

Also it's worth separating persistent data (e.g. settings) from the playthrough data (the first one shouldn't be affected by things like starting a new game or creating a new profile).

well, deepseek told me to save the stuff locally with json as u just said, and synchronize it in cloud to use the data for online features. Ty for the tips

Why is my object marker dysfunctional?

#

Oh god I didn't realise how big it was sorry for covering the screen

#

Looked a lot smaller in VS

#

To be more specific the world to screen point seems to mess up a bit. The markers either aren't visible or are moving to thin air

#

Ah I didn't know WorldToScreenPoint was in pixels

#

Still doesn't solve my issue unfortunately. Would this be more suitable in #📲┃ui-ux?

I have a prefab in a scroll rect with a content size fitter applied on the Content parent. I want to be able to drag the item from the scroll rect into another point in the scene. (See image 3)

However, I want the initial object in the scroll rect to stay in place as a form of infinite source (akin to Little Alchemy), so I want to instantiate another prefab with slightly different logic. I am using the onBeginDrag, onDrag and onEndDrag function to drag the object.

It all works well up to the point of instantiating the prefab. When I click on the prefab, it instantiates. However, it doesn't trigger the OnDrag event on the newly instantiated prefab. When I try to pass the EventData from the Scroll rect prefab to the newly instantiated prefab (see image 1), it still does not work. In other words, forcing it to activate OnBeginDrag does not work. I have been stuck with this problem for the whole week and I am wondering if any of you could help.

Note: DragDrop script (image2) Is only on the instantiated prefab. The OnEmotionInvClick (image1) is only on the scroll rect prefab.

It's because it's managed externally by BaseInputModule (or a class that derives from it). That script hasn't registered the new object as dragged. I wasn't investigating this script much, but it feels like it would take a lot of trouble to make it to work externally. I suggest you one of these:
a) Start Coroutine (or any other similar feature) in your OnBeginDrag method and every frame do whatever you would want to normally do in OnDrag method, then delete OnDragMethod. Also stop the Coroutine once you release the pointer.
b) Similar solution, but do it in Update instead of coroutines. Create a bool that stores the information about object being dragged, and check the value inside of Update method.
