2D cameras might just need to pan when a cursor hits an edge

rough orbit
#

yes

polar acorn
#

@tulip nimbus any chance you can get a video of what it's currently doing?

rough orbit
#

no, 748 times

buoyant knot
#

my point is that you can make good arguments for 2D cameras to just do them custom.

#

but writing your own camera from scratch for 3D? fuck that

i’d also search Time.TimeScale via IDE to know if you’re messing with it

tulip nimbus
#

Okay for a bit more context if you dont mind me still asking this:

There is a prefab which is called. The shown code is in its Awake() function. So everytime the prefab is created(like a bullet) it aims at the cursor once, and then the prefab travels towards the position it got at the moment it got Instantiated.

However, as stated, they all aim And only then at the Plane Camera when i give it the "Main Cam" tag

Again thanks for your help, patience and time

polar acorn
#

You can use unscaledDeltaTime instead, or find where you're setting it to 0 and just not do that

#

since it seems like you never intended to

just as a suggestion by the way, for stuff like "animating" volume over time there are good "tweening" libraries out there, they are convenient (BUT not always the best performance wise)

tulip nimbus
#

The Plane is in the "follow" space inside the Cinemachiene Virtual Camera component

rough orbit
#

Thanks digiholic and sidia. I'll find another way to prevent stuff from happening in the background.

#

Prob just disable enemy updates

I don't think the virtual camera needs the main camera tag but I also don't think that would affect anything since it doesn't have a camera component on it

tulip nimbus
#

oh yeah i also gave it the tag but it didnt change much :(

#

Maybe it is facing the mouse, but the wrong side of it?

tulip nimbus
#

do you mean movement? Because i didnt programm that yet

#

they just stand still atm

polar acorn
#

No, I mean the sprite you're using. You're angling the green arrow towards the mouse

#

Can you show the inspector of a bullet with the transform gizmo visible?

tulip nimbus
#

like this?

ddd.PNG
polar acorn
#

In the scene too, to see where the arrow is

steep rose
#

he may be using global gizmos

#

unless they are always local (i think it defaults to global)

polar acorn
#

Right, make sure you're on local.

im so sorry if this isnt right. ITs like this on local and global

i have an itch that the solution is really simple and im just not showig you guys the right things haha

#

so they're the same right now

tulip nimbus

#

oh, then your good

polar acorn
#

Let me try to construct a scene as close to what you have as I can and see

tulip nimbus
#

or parts of it

polar acorn
#

It'd probably be faster for me to just rebuild it

tulip nimbus
#

i dont want you to download anything but perhaps there is a function to share or smth

steep rose
#

then you cant

polar acorn
#

I have it mostly done, I just need to have the cinemachine camera follow something

tulip nimbus
#

yeah you guys are the pros here haha

patent imp
steep rose
rough orbit
polar acorn
#

Yeah, with the camera following an object, and the script you've shown put in Update on a sprite, orthographic camera, using cinemachine, I'm getting exactly what you'd expect, the arrow faces the mouse cursor even as the circle moves. There is definitely something else going on here. Can you share the full script for the bullet?

image.png
#

Ah, the screenshot didn't include the cursor, but it's pointing at the cursor and not the circle

tulip nimbus
# 
 void Update() 
 {

     FaceMouse();
 }

 void FaceMouse() 
 { 
     Vector2 mousePosition = Input.mousePosition;
     mousePosition = Camera.main.ScreenToWorldPoint(mousePosition);

     Vector2 direction = new Vector2(mousePosition.x - transform.position.x, mousePosition.y - transform.position.y);

     transform.up = direction;
 }

This is basically all the code, i replaced it to this again, before the big part was in the Update function since i wanted to put some other stuff there but it works the same ig

polar acorn
#

It looks like your bullets are facing the plane, rather than the mouse

What scripting (C#) tutorial do you guys reccomend? English isnt my first language so keep that in mind.

tulip nimbus

# tulip nimbus

Eh, let's see the !code for Plane Behaviour as well. Maybe it's doing some shenanigans to the prefab that's affecting all of the children of it? I'm not sure what but at this point all the things I've expected it to be have all been fine so I'm gonna just check everything

Yeah, a perspective camera has the mouse at the position of the camera. It won't actually be able to detect the mouse movement

queen adder
#

😭

polar acorn
#

it'll always be at the same spot, where the perspective converges

#

you'd need to manually offset the mouse position to use perspective, but for a 2D game you probably want orthographic anyway

# queen adder 😭

It was really really demotivating for me when i started. Im lucky because i have alot of time on my hands currently since i just graduated.

Even if you do a bit every day and if you dont give up it adds up.

The start was the hardest part. I also recommend learning by just doing. You get faster and better over this time even if its just a little. Plus it is productive. When it comes to coding you NEVER stop learning and you can always improve. The hard part is always starting. But even when you have little time you will thank youself that you started.

im still a beginner but i learned so much by just doing this current project and asking people that really know

# queen adder mongolian

Thats intresting and i see the problem that there are not many tutorials in mongolian (if any) on programming. Maybe just follow what the people in the tutorial are doing for now. Programming (in my opinion) is alot more about logic than english. So if you know what each code block does and you can learn to combine them

English also isnt my first language but i learned it by watching youtube and taking courses and i got better

Hello everyone, I have this class which holds some methods used by my player and my enemies. Each element holds a hurtbox and a hitbox.

#

The thing is that my enemies are controlled by a navmesh and their rigidbody is kinematic. And when trying to apply a knockback, it gets pretty buggy, even disabling the path following and making it dynamic.

#

Is there any efficient way to handle knockback with navmesh controlled elements?

Either a class member variable or at least replace this:cs if (rb.transform.GetComponent<NavMeshAgent>() != null) { rb.transform.GetComponent<NavMeshAgent>().isStopped = false; rb.transform.GetComponent<NavMeshAgent>().updatePosition = true; }
With this:cs if(rb.TryGetComponent(out NavMeshAgent agent)) { /* agent.thisAndThat */ }

        mouseY = Input.GetAxis("Mouse Y") * mouseSens * Time.deltaTime;

        transform.rotation *= Quaternion.Euler(0, mouseX, 0);

        camRotation -= mouseY;

        Mathf.Clamp(camRotation, -90f, 90f);
        mainCamera.transform.rotation = Quaternion.Euler(camRotation, 0, 0);

Hello good people, I'm having great troubles, and have been struggling with this issue for awhile in Unity. It seems that I cannot nail down getting smooth camera movement with player movement, specifically in fps. I got fed up of reading the docs trying to figure it out, and asked chatGPT, but it wasn't able to come up with a working solution for me.

wintry quarry
mighty compass
#

So all movement is smooth, but as soon as I attempt to rotate the player/camera by moving the mouse, everything looks jank, and as if it's lagging behind

#

I think the camera is updating its position too many times in relation to the RB, and this is causing it to jump around

wintry quarry
#

Isn't it just a child of the player?

mighty compass
#

I'm pretty good at Java, javascript, HTML, CSS, but I'm new to C# as hindsight

wintry quarry
#

Second - because you';re doing this:

playerObject.transform.Rotate(0, mouseX, 0); // Horizontal rotation on player.```
You are breaking your Rigidbody interpolation
#

so that will immediately lead to jitteriness

#

you should never touch the Transform of a Rigidbody directly

mighty compass
#

yes, I assumed I had to move the camera seperately from the RB in order to prevent x axis rotation of the RB

#

ah

wintry quarry
#

To fix the Rigidbody interpolation issue you can replace that rotation code with:

rb.rotation *= Quaternion.Euler(0, mouseX, 0);```
#

You'll also want to double check that interpolation is enabled on your Rigidbody

mighty compass
#

I also usually use notepad++ and I find visual studio really annoying because it keeps formatting my code and doing stuff for me lol, know how to disable it?

#

Thankyou

#

I just dont want my entire playermodel to rotate on the x axis, is the only thing, that's why im doing it to the camera only

wintry quarry
mighty compass
#

I have

short hazel
mighty compass
#

Ill try your fix

#

It's just basic stuff like this: private void UpdateCameraPosition() { cameraObject.transform.position = playerObject.transform.position + new Vector3(0, headAdjustmentMeasurement, 0); }

#

I would write this to look cleaner imo like: private void UpdateCameraPosition(){ cameraObject.transform.position = playerObject.transform.position + new Vector3(0, headAdjustmentMeasurement, 0); } xD

wintry quarry
mighty compass
#

Just how I'm used to it in Java

#

Thankyou, I actually spent a lot of time searching for it before, and couldn't find it xD

#

What's the option that automatically fills words for you, sometimes I will have a Class name with a keyword in it, and it tries to fill my code with my classname instead, when I'm trying to use the keyword.

mighty compass

is it "Word Based Suggestions in files handled by TextMate grammars"?

#

#

Intellisense code completion
As long as the name you type is cased roughly identically to the keyword, it'll prioritize the correct one

mighty compass
#

It seems to be broken for me xD

short hazel
#

If you have a class Int { } and type "Int", it's going to prioritize Int over int because it's closer

#

Don't name types the same as keywords or common identifiers

mighty compass
#

I don't, but sometimes I will have a keyword in a class name like for example IncrementPlayerInt or something, and it'll just keep suggesting it lol

short hazel
#

It also bases itself on usage, stuff you used before will appear more frequently. Not sure if there's a way to change that behavior

mighty compass
mighty compass
#

Because I'm quite new to programming, I've only been studying it for about a year, year and a half

#

So the extra reps of typing helps me consolidate it

Maybe if I interpolate the camera position update?

#

The ray that ScreenPointToRay gives is on the camera's near clipping plane, not (always) exactly on the camera

#

And the direction is not always the camera's forward, unless if it's an orthographic camera I guess

#

Have you confirmed that the raycast code is running?

#

Okay your issue stems from here:cs initialMousePosition = Input.mousePosition; // ... dragPlane = new Plane(targetObject.transform.up, initialMousePosition);
Input.mousePosition is in screen space but you are using it for a world space plane

https://gdl.space/rekupufowi.cs Okay, I interpolated my camera for smooth movement, and I can see it coming out of the player model, and the playermodel sortof glitching all over the place while moving, not sure why

Just getting the basics down, the movement is so jank, it looks like the player model bounces back and fourth

verbal dome
#

I don't see why you are lerping the camera position in UpdateCameraPosition

mighty compass
#

I don't need to, I know

verbal dome
mighty compass
#

xD

#

I wanted the camera stable so I could sortof see what's going on

#

And now I can, and I see the playermodel glitching back and fourth really quickly when moving in one direction (the shadow)

verbal dome
#

Is there a reason to have the camera and playercamera objects separately?

#

Also a video of the issue would help

mighty compass
#

playerCamera is the camera, player is the player object/model

#

kk

verbal dome
#

Ah, I just saw MainCamera and thought that's used here too

#

Btw this will break interpolation IIRC: ```cs
rb.rotation *= Quaternion.Euler(0, mouseX, 0); // Horizontal rotation on player.

mighty compass
verbal dome
#

rb.MoveRotation would respect interpolation

#

If you want to continuously rotate a rigidbody use MoveRotation instead, which takes interpolation into account.

mighty compass
#

eventually I'd like to make it multiplayer, so each player object is spawned in with their own cameras, I know I'm very new, but just for possibilities in the future

#

okay, thankyou

Try commenting out the whole rb.rotation = code for a moment, see if it still jitters when you walk

slender nymph
# devout flume Is it possible to have a `BaseMaterial`, whose color is `ffffff`, and then apply...

if you want to change the color on a single object then you will need to instantiate its material so it does not affect the other objects using the same material. getting its renderer.material will automatically instantiate the material. or you can do it manually using Object.Instantiate
(this information is assuming you want to do this at runtime, edit time requires separate material assets)

My main project is to make a creation game in which you would be able to position elements around, change a lot of properties I define. Color is one of them. I developed the project in ROBLOX to realize that the platform kind of sucks, specifically when it comes to the physics engine, and I'm not even talking about the overall way the platform treats developers. Trying to see if Unity is a good choice but it's definitely not the same ideology behind 😅

#

Thank you for your help

steep rose
#

or deltatime for other movement method other than RB

#

depending on what you are doing ofc

ember tangle
# verbal dome It also sounds a bit like your movement depends on framerate

fps is 200 - 400, the command itself is very simple ```public class MoveDirection : ICommand
{
Vector3 direction;
Entity entity;
public MoveDirection(Vector3 direction, Entity entity)
{
this.direction = direction;
this.entity = entity;
}
public void Execute()
{
entity.rigidbody2d.AddForce(direction);
}

}```

slow hollow
steep rose
#

deltatime isnt framerate dependant afaik

verbal dome
#

Well you'd normally only use deltaTime (fixedDeltaTime) with MovePosition or rb.position, not with forces or velocity

#

Since addforce already uses deltatime by default

steep rose
slow hollow

im not saying use deltatime for forces, im saying use it other than RB movements so like Move() or something along those lines

This is what the command invoker looks like: ```public class CommandInvoker : MonoBehaviour
{
private static Queue<ICommand> commandBuffer;

void Awake()
{
    commandBuffer = new Queue<ICommand>();
}

void Update()
{
    if (commandBuffer.Count > 0)
    {
        ICommand command = commandBuffer.Dequeue();
        command.Execute();
    }
}
public static void AddCommand(ICommand command)
{
    commandBuffer.Enqueue(command);
}

}```

devout flume
#

Yes for sure ! I ofc expect you to have lives, that's completely normal. You're kind enough to help people, that's already a huge thing

verbal dome
slender nymph
#

the only time AddForce should be called in Update is when it is a one-off Impulse force

steep rose
#

just look at quake for example and what framerate dependency does to games

verbal dome
#

It's a decent idea to keep your AI stuff in fixedupdate anyway, althought I've never seen anyone mention it except me

#

Or your own update loop but that's more complex

ember tangle
# verbal dome It's a decent idea to keep your AI stuff in fixedupdate anyway, althought I've n...

hmm. I do have the AI get the command through a fixed update: ```private void FixedUpdate()
{
foreach (var entity in entities)
{
//get cell where entity is at
Cell currentCell = flowField.GetCellFromWorldPosition(entity.transform.position);
//get move direction from flow field cell
Vector3 moveDirection = new Vector3(currentCell.bestDirection.direction.x, currentCell.bestDirection.direction.y, 0);

    ICommand command = new MoveDirection(moveDirection * 1000f * Time.deltaTime, entity);
    CommandInvoker.AddCommand(command);
}

}```

verbal dome
#

Yeah that doesn't help if you're executing it in Update

ember tangle
#

the thing is the movement works perfect when I apply the AddForce at the keypress

#

it just doesnt work as a command

verbal dome
#

Not directly related but worth mentioning that by default, AddForce will already be multiplied by fixedDeltaTime

#

So you have some redundant multiplications there

ember tangle
#

Do I need a seperate command invoker for player inputs? I dont want to do an anti-pattern with the commands.

verbal dome
#

Can't you execute the command from FixedUpdate instead?

#

Or if you need some commands to be executed in Update then you could have two different commandbuffers

#

Btw are you doing flowfield pathfinding or something? For an RTS?

ember tangle
#

I do have flowfield pathfinding in the project for now. its a roguelite that may have a lot of enemies / pathfinding projectiles etc

verbal dome
#

That's fine in FixedUpdate, because deltaTime actually returns fixedDeltaTime, which is constant, when in FixedUpdate

#

But in Update it will change with your framerate

#

I must say I have never seen the command pattern used for continuous movement 🤔

mighty compass
#

delta time so far has never seemed to fix a single one of my issues

#

It seems almost useless

silk night
verbal dome
mighty compass
#

I think just using the update functions correctly will eliminate the need for delta time. I also know nothing about this editor so far though lol

verbal dome
mighty compass
#

Can barely get smooth movement

verbal dome
#

Top 2 things you shouldn't use deltaTime with is mouse input and forces

mighty compass
#

Like what does it do

verbal dome
#

Want to add 1 to a float over 1 second? Add Time.deltaTime to it in each Update

mighty compass
#

Doesn’t just give you the time in seconds from the last frame?

#

I see

verbal dome
mighty compass
#

Ah

verbal dome
#

If the frame took longer to finish then deltaTime will be greater

#

So it will account for that

mighty compass
#

That’s pretty cool, but isn’t the update function supposed to do that anyways?

#

It occurs every frame?

verbal dome
#

Nope, it just runs each frame

mighty compass
#

Ohh I see now

#

So it keeps track of calculations regardless of the frame rate

#

So if there’s massive frame drops, there’s no lag in calculations or logic that would’ve occurred

verbal dome
#

Lets say you add 0.1f to your float each update
If you have 10 fps then it will take 1 second to reach 1
If you have 100 fps then it will take 0.1 seconds

mighty compass
#

Ah

#

So it’s useful for server side logic, or anything where your client has to keep track of things over realtime basically

#

Man there’s so much I don’t know about these engines xD

verbal dome
#

Not sure about that. Pretty sure that server side logic happens at fixed intervals

Hello, I'm using the code below on an enemy in a game I'm making so that it will walk to random points forever until it spots the player, but I was wondering if anyone had any ideas for making this a bit more realistic. It doesn't need to be anything crazy but right now there are many instances where it will just keep walking back and forth and I want it's path to be a bit more realistic than that

    {
        Vector3 randomPoint = center + Random.insideUnitSphere * range;
        NavMeshHit hit;

        if (NavMesh.SamplePosition(randomPoint, out hit, targetDistance, NavMesh.AllAreas))
        {
            result = hit.position;
            return true;
        }

        result = Vector3.zero;
        return false;
    }

    void Patrol()
    {
        if (agent.remainingDistance <= agent.stoppingDistance)
        {
            moveRange = Random.Range(2, 5);

            if (RandomPoint(transform.position, moveRange, out point))
            {
                targetPos = point;

                agent.SetDestination(point);
                Debug.DrawRay(point, Vector3.up, Color.blue, 1.0f);
            }
        }

define "realistic"

you mean you wait before you go to another point?

do you want the enemy movement slower when patrolling?

#

gaunt solstice
#

well realistic was a poor choice of words

rich adder

give your enemy some random times to pause and do something else instead of just hitting each point like a clock

teal viper

Make it go grab a coffee every now and a while to make it more realistic.

rich adder

one my enemy reaches a patrol point it usually looks around, picks a random look at target and IK turns its body or does something before going onto next point

verbal dome
#

I did that just recently

steep rose
#

i am in the making of a custom navigating enemy and what i do is it just to stay still for 5 seconds

#

then to go to another point

gaunt solstice
#

since the point where it will walk appears at a random point within a certain radius from the npc, sometimes those points will appear directly behind it and it'll do a full 180 and walk towards it, and then do it again so its just walking back and forth. so I mainly just want points to not appear directly behind it that much

verbal dome
#

Pauses do sell it quite well, but turning around constantly can still look a bit odd

rich adder
teal viper
verbal dome
steep rose
#

you could just make it so it cannot pick the previous point twice

#

i mean you could also increase resolution of points so it practically cannot create the same point twice 🤷‍♂️

rich adder

yeah since they're random and the enemy keeps moving it's already extremely rare it'll hit the same point twice

Theres a very small chance that it would pick the same point, its using insideUnitSphere

generate a point, check the dot if its within range add it to the possible points. If not keep iterating

Yeah compare the dot product of (playerPos - lastPos).normalized and (playerPos - randomPos).normalized

#

If it's too high (say, over 0.5) then generate another point

rich adder
#

sorry poor drawing skills lmao

verbal dome
#

You can also use Vector3.Angle instead of Vector3.Dot if that's more clear to you

gaunt solstice
#

thank you, i will try some of these out

rich adder
# gaunt solstice thank you, i will try some of these out

you see the blue is the number on the right, the dot product cs float dot; Vector3 dir; private void Update() { if (target == null) return; dir = (target.position - transform.position).normalized; var forward = transform.forward; dot = Vector3.Dot(forward, dir); }
closer to 1 = infront / closer to 0 = sides and anything below 0 is behind
replace the target.position for the generated point and do the rest based on dot or angle

Hitting on a (you got it) bit of snafu

#

I have a script that creates a virtual plane, and i should be able to drag an object along that plane

#

I want it to only be able to be dragged in one axis, so, in all of my wisdom, implemented Vector3.Project

#

However.

#

!code

eternal falconBOT
nocturne kayak
#

This is the script running on that

#

Thing is, if at line 54 i replace "Vector3.Project(hitPoint, transform.up);" with just hitPoint, it drags fine, just not on that axis

#

So, what am i not getting about the Vector3 Project?

teal viper
nocturne kayak
#

Huh

#

How should i proceed then?

teal viper
#

You could transform that point into the object local space, project it on the direction vector, then inverse transform it back into world space.

#

Or just assign it to transform.localPosition instead of the last step

#

Though, you might need the direction vector to be in local space as well🤔

#

Don't have much time to think about it.
You should do some math/ sketching on paper before actually writing the code.

nocturne kayak
#

Yeah

#

I'm trying to look into TransformPoint but no luck there

I'll try editing that tomorrow

        {
            //print("i" + i);
            line += "" + i + ":[";
            for (int j = 0; j < rooms * 2; j++)
            {
                //print("j" + j);
                line += layout[i, j] + ",";
            }
            line += "]\n";
        }
        line += "]";
        Debug.Log(line);
    }
#

trying to print the whole array into the debug console, only two lines show up

#

after i clicked on it you can see all the lines

#

Guys am having a strange issue with my code, basically my PlayerManager code calls the function Collisioni() from Tile.cs when it touces the tile and should return an array containing the object that that object is touching, but it only returns half of what is touching. I already tried debugging and the results are:
if i try to print the elements of the list at the end of OnTriggerEnter of Tile.cs it gives all the collisions ( is 4 object in this case), but when i print on Collisioni in Tile.cs it only gives me 2 of them.

sand snow
#

whenever i try to make a new script it cant open, and im pretty sure its because unity cant find my visual c++

astral falcon
sand snow
#

no it just says "check external application preferences"

#

and when i got to preferences i see the thing to change it to visual c++ but visual c++ isnt an option

#

the only option is "open by file extension"

astral falcon
kind rover
#

i thought of that and i tried to do a while statement in the Collisioni function while(hitCollider.count<2){ Debug.Log("waiting") }
but it just gives an infinite loop

sand snow
#

should i just delete unity and visual c++ and just reinstall? i feel like there has to be a better way to fix this

astral falcon
astral falcon
#

Did you install it with unity hub along with a unity version?

kind rover
#

isnt it what am doing? passing the collisions of the tile through Collisioni() ??

sand snow
kind rover
#

oooh you mean that

#

i did that before and gives the same issue i switched up to gameobject to see if it was a problem of collisions

astral falcon
# kind rover isnt it what am doing? passing the collisions of the tile through Collisioni() ...

Physics system is firing both ontriggerenter at no specific order, so you dont know, when the actual collision gets added. The tile should call the player, not the player ask the tile on its own collision detection. Lets say, player hits tile (collision 0 happens) and gets the collions of the tile, its 1, but then the tile progresses its own ontrigger check and adds to the list, but the list has already been fetched by your player.

#

Not sure its clear. The player got the current list before your tile was able to add and check its own collisions. shorter version 😄

languid spire
#

Also, the List is only created once and added to, so the count will increase with each Trigger

kind rover
#

yeah but by adding a while statement inside Collisioni() in Tile.cs shouldnt it wait until for example hitCollider.Count > 2 so for atleast this case should give me all 4 collision

#

but it just gives an infinite loop

astral falcon
kind rover
#

like this for example

#

in this case the collision are 4 so it shouldnt give an infinite loop

#

i did this and it shows me that it prints the results before it could even insert the collisions in the list

image.png image.png
#

so the issue is that

#

the first 2 logs in the console are the Debug.Logs of Player.Manager

#

is there a way to make the playerManager wait or should i approach it in an other way

what if i use a boolean in Player where it only call the function Collisioni when its true , and the bool its true only once all the collision of Tile are stored in the list?

#

but at this point i should use OnCollisionStay instead of OnTriggerEnter

#

it works now like this @astral falcon thanks for help ❤️

#

just asking but how do i know if an object registred all collisions, cause in this case i said if ontriggerenter has been executed 4 times its all of them but if the collision are 3 or even 5 what do i do

#

whats the condition

neon ivy
#

I'm getting stuck with vectors.
I have a vector which is (moveInput.x,0,moveInput.y).
I'm trying to rotate this vector based on which way the freelook camera is looking, ignoring the y direction.

I tried to do

Vector3 output = Quaternion.AngleAxis(Vector3.Angle(Vector3.forward, new Vector3(mainCam.transform.forward.x, 0, mainCam.transform.forward.z)), Vector3.up) * new Vector3(moveInput.x, 0, moveInput.y);
``` but this doesn't work and starts to mix up controls when the camera is rotated.

I think Vector3.Angle is messing with me but I have no clue how to fix it. anyone know?

#

you're adding additional force for each contact in the collision

#

the scenario where you're hanging half off the platform has fewer contacts

#

so less force is being applied

#

You can do Debug.Log($"Contact count: {other.contactCount}"); to check

#

There's also a couple of if statements in there

#

so even if the contact count is the same, sometimes not all the contacts will have a force based on this code

languid spire
#

Also the foreach will only ever run once

wintry quarry
#

Oh yeah true - that's wild

#

it should really just be:

var contact = other.GetContact(0);
// do stuff with it

And get rid of the loop entirely

#

so really what's happening is that the first contact in some of these is satisfying the condition, and in others it is not

int times = 0;

Then every time you add force
