Hi everyone,
I'm trying to setup my Unity project. I'm using VS code as external tools. My project has a multi-root setup. I saved a [project-name].code-workspace in the root directory of the project path. Now in the editor external tools arguments, I'm using "$(ProjectPath)/[project-name].code-workspace" -g "$(File)":$(Line):$(Column).
This works as expected when opening the project from unity : workspace is loaded, file script and line number are opening as well as it should.
Still this arguments in the external tools editor window is common for all the Unity project which use the same editor version, so it is fine only if I'm working on the correct project.
Do you know if there is an argument (like the $ProjectPath) which defines the project name ? Or anything like this I could use ?

Non-convex MeshCollider with non-kinematic Rigidbody is no longer supported since Unity 5.
does anyone know how to use MeshCollider with kinematic Rigidbody (because I AddForce to it) ?

Non-convex MeshCollider with non-kinematic Rigidbody is no longer supported ...
You need to use a convex mesh collider
If its not accurate enough to your shape, you can use multiple convex colliders, or preferably multiple primitive colliders (box, sphere, capsule) to approximate the shape

Why not just generate two.. at specific locations?

Hey, I have an inventory which has slots, and i have a hotbar (which is a different gameobject) which has 5 slots. I want to do a drag & drop system, like dragging an item frm the inventory to the hotbar. I tried to use the interfaces for that, but in my hotbar, i have the interface "IDropHandler", so the method OnDrop as well, but the variable "pointerEventData.pointerDrag" returns me the slot on the inventory where the item was before dragging... someone has an idea for that?
I just missed an information, it should fix the pb, thanks anyway ^^'

I'm trying to make the code generates only 2 obstacles, why is it generate 3??
int Genrated; isn't a static variable, so it's independent for each script instance. It means that one script can have a different value than the other one. In other words, incrementing it in one script won't affect the other scripts.
Oh wait, I think I misunderstood the scenario. 🤔

Well, when I'm looking at this code, it shouldn't spawn more than 2 objects, unless there are several instances of this script on the scene.

I've got a ball that follows the mouse on every Update().
debugBallPos = debugBall.position;
debugBall.position = Vector3.Lerp(debugBallPos, mousePos, 0.1f);
debugBallPos is a vector 2 version of the debugBall's position.
Line 2 just lerps it to the position of the mouse.
My question is, how do I constrain it to not go farther than a limit from the skeleton's torso
dusk apex
Acquire the distance between mouse and skeleton and set the target constraint of Lerp to skeleton position + mouse direction * Mathf.Min(distance, max).
Note: this would produce a circular max distance constraint.

Raycast hitting nothing isn't a problem in of itself, but if your code is trying to do stuff like "getComponent" on nothingness, then yeah it will freak out.
You probably just need a null check. Dunno if there's some other way.
ancient sail
Raycast hitting nothing isn't a problem in of itself, but if your code is trying...

You just put in an if statement that check that the thing you hit isn't null.

That way it won't do anything when it hits nothingness (returns null)
soft shard

i thought it just needed a collider
For collision to happen, 2D or 3D, at least one of the colliding objects do also need a rigidbody, since your using 2D colliders, you should also use a 2D rigidbody on whichever object youd (by default) want to be affected by gravity, and physics, though the gravity part is optional

Adding a single impulse force in update is fine

It is possible, though for the case you described, I think it would be better to treat your item class as just data, in a serialized class, then create an instance of it in your weapons, armor, potions, etc classes, either as a public or [SerializeField] to set it through the inspector (serialized field is a more cleaner approach), since it sounds like your weapons etc will want to use or depend on data set from your item, another approach could be inheriting from your item class (or using interfaces), if every item like weapons, potions etc may share functionality too

Might be worth moving it over to a class and controlling it's initialization with an initialize function

can unity detect collisions if im manually updating the positions?
i have one object manually moving left (position -=1) and another moving right (position +=1), will the oncollisionenter function detect the collision?
right now my code for whatever reason isnt detecting collisions and im not sure if its because im manually moving objects or something else
hexed pecan
MovePosition might work.
Transform.position does not
Or if it does, it is pure chance
somber nacelle
can unity detect collisions if im manually updating the positions?
you need a rigidbody on at least one of the objects for collision messages to work
and if you have a rigidbody you may as well move using that instead of teleporting it via the transform
hexed pecan
Yeah, sounds like you might as well use rigidbody.velocity to move them at a constant speed

Is there a difference between loading the scene the first and the second time?

i'm gonna guess you have a DDOL object that loses references because you change/reload the scene

When i load it aigan a object is not existant anymore which executes crucial code

a singleton?
ashen yoke
off to google whats a singleton
somber nacelle

Should be a singleton
somber nacelle
so are you expecting us to magically know your code to provide an answer or do you want to maybe share relevant code and errors so i can helpfully point out for a second time that when you reload a scene the DDOL object won't keep the same references to non-DDOL objects because they are different objects
ashen yoke
if it is a singleton most likely you are not properly cleaning up the static field
as a result the gameobject is destroyed but the wrapper is left in the field and doesnt equate to null
but yeah, all that is just fart in the wind until you show the code

heady iris
i'd suggest lerping a hue value
and then using that to compute colors
consider Color.HSVToRGB
it converts a hue, saturation, and value to a Color
hue is the kind of color it is, saturation is how strong the color is, and value is how bright the color is
solemn raven
i'd suggest lerping a **hue** value
please show me a simple code, im lost when it comes to shaders and colors, even the simplest thing dizzles me.

Color.HSVToRGB(0f, 1f, 1f) will spit out red

while (t < 1f) {

Any reason I shouldnt put rigidBody on the environment, instead of the player?
I've got Players, and Enemies - they don't need to collide, but both should collide with environment. So, I can have a RB on Player and Another on Enemy, -or- I could put 1 on the environment...
hexed pecan
It needs to be on the moving objects
somber nacelle
why would you want the environment to have physics?
hexed pecan
Simply put
heady iris
you COULD put a kinematic rigidbody on the environment, I guess
red scarab
why would you want the environment to have physics?
environment would be kinematic or static
hexed pecan
You could, still need a rb on the characters though
heady iris
but then you'd need a non-kinematic rigidbody on the player anyway
somber nacelle
well making it static means you'd still need a rigidbody on your characters for collision messages
red scarab
but then you'd need a non-kinematic rigidbody on the player anyway
source link?
rain minnow
If the environment isn't moving around being affected by everything, then static or kinematic (in certain instances) are fine . . .

since static was an option for the RB it sounds like this is probably for 2d. so this may help clear things up: https://unity.huh.how/programming/physics-messages/3-collision-matrix-2d
hexed pecan
Maybe for continuous collision detection you might wanna add a RB to some walls
somber nacelle
static rigidbody counts as static in that matrix

correct, 2d

you need to create an interface, then
deft cape
mfw when I asked my friend if interfaces were in unity and they told me no:
heady iris
well, interfaces aren't in "unity"
they're a C# thing
but I would agree that you can use interfaces when working in unity :p
deft cape
how hard you think interfaces are to setup cause im in game jam and im debating just manually hard coding in each reference cause of time
ancient cloak
literally trivial
heady iris
how hard you think interfaces are to setup cause im in game jam and im debating ...
very very easy
ancient cloak
the methods you want as part of the contract, define them in the interface, inherit from the interface, and you're off to the races
heady iris
indeed
you won't even have to change anything in the concrete classes
other than declaring that they implement the interface
then, you can use the interface type in place of that Component type in your code
ancient cloak
an interface is literally just that, like the plug/socket combo's in your house are interfaces
heady iris
as Stropheum said, it's a "contract"
ancient cloak
you don't need to be an electrician but you can arbitrarily and modularly wire any electrical device into your home because you just rely on the interface
heady iris
it's a promise that you can do X Y and Z
or, in this case, just a promise that you can do X
tropic quartz
I'm a nublet and even I find interfaces relatively easy to use, shouldn't be a problem.
deft cape
I came from UE5 so I knew what interfaces were, I just asked my friend if unity implemented them when we were setting up interaction system and he told me no so I just ran with it and now im like "ok surely there has to be an easier way thats at least similar" lmao
ancient cloak
in this case, it would be like
public interface IWallSocket
{
public void PlugIn();
public void Unplug();
public void SetActive(bool isActive);
}
every language has interfaces and they're all pretty much the same
only thing is in unity (and i hate this) you can only serialize concrete types to the inspector
which is fucking annoying
heady iris
[SerializeReference] correctly handles abstract classes
although you have to write your own property drawer
zoop
ancient cloak
abstract classes but not interfaces
which is kind of pedantic but it fucks with the coding by contract paradigm
deft cape
in this case, it would be like
```cs
public interface IWallSocket
{
public voi...
So you would write this on the class that would be calling the functions from the game objects ye?
ancient cloak
no you would tell your class to implement it
public class DishWasher : IWallSocket
{
public void Plugin()
{
//do things a dishwasher does when you plug it in
}
public void Unplug()
{
//do unplug things
}
public void SetActive(bool isActive)
{
//turn the dishwasher on or off
}
}
so then you can have like a house electrical controller that does something to the effect of
ancient cloak
public class HouseElectricalSystem : Monobehaviour
{
private List<IWallSocket> _homeAppliances;
public void OnPowerLoss()
{
_homeAppliances.ForEach(x => x.SetActive(false));
}
}
lmao
ancient cloak
so the house electrical system doesnt give a shit if it's a dishwasher, a vibrator, a stove, your phone. all it cares is that it's something you plug in
ancient cloak

is anything unclear on interfaces right now?
i started watching a tutorial ontop of the explanations and I think I get it now although the only thing im confused about is creating the interactable do I just make a C# script or somethin and then change it to be that
heady iris
yeah, if you create a new C# script in unity, it's pre-filled with some stuff
ancient cloak
my workaround is usually like some kind of composable attribute system for like-things
heady iris
throw that out and write an interface
ancient cloak
and then i can make scriptable object instances for each configuration
heady iris
i usually just create a new file from my code editor
ancient cloak
good luck on your game jam btw
rule of thumb is get it done. if you catch yourself trying to be clever in a game jam your game is gonna suck
i've been burned multiple times getting inspired to make a really elegant system
deft cape
throw that out and write an interface
so I do just make a C# script and chuck it all out ye?
and also I don't need to attach the interface like a component right I can just add it in the code to the script for the object in the class section ye?
heady iris
correct: the interface is not a component
ancient cloak
public interface IMyInterfaceThing
{
public void MyDeclaredMethod1();
public void MyDeclaredMethod2();
//and so on
}
convention is to previx interfaces as generally like I(Verb)
like ICompressable, or ILovable
those are adjectives
tropic quartz
Yeah, I think you actually can't attach an interface to an object even if you try.
rain minnow
The interface does not physically exist within Unity. You just implement it from a class . . .

I need to display a bunch of spheres with a predetermined size and color at a bunch of different places in the world, without collision. I'm aware of GameObject obj = GameObject.CreatePrimitive(PrimitiveType.Sphere);, but this creates colliders and instantiates a gameobject, when I just need the mesh since there are a lot of spheres. How can I achieve this?
tropic quartz
Would it be bad to just use the default unity sphere? And just set colors with material color value.
Wouldn't need colliders.
tulip mauve
how would I do that? GameObject.CreatePrimitive(PrimitiveType.Sphere); creates colliders by default and I feel like creating and immediatley destroying them is bad practice
tropic quartz
Just instantiate a regular gameObject prefab, with the meshrenderer using the sphere.
Oh. I guess you asked for pings. @tulip mauve

Hi, I was thinking of a problem, that I dont really know how to properly explain (because I dont really know how it works tbh), but it was about how unity deals with the registration of listenners to callbacks via interfaces (e.g. The input system Map class Callback interface with actions callbacks or the event system with Interfaces for each of the UI actions) where you just determines a contract via the interface and the class will listen for when something happens.
Is this someway achievable or, as I think it is, is more complicated and takes more "behind the scenes" work by unity for it to work properly?

Does anyone know how to make a certain input a holdable button?
I’m making a platformer and it’s kinda ruining the flow of the game because I have to time my jump button every time I land, if I click too early it doesn’t input and makes for a worse experience.
Some help would be great

Hi, I was thinking of a problem, that I dont really know how to properly explain...
public class Example : MonoBehaviour, IPointerDownHandler
{
//Detect current clicks on the GameObject (the one with the script attached)
public void OnPointerDown(PointerEventData pointerEventData)
{
//Output the name of the GameObject that is being clicked
Debug.Log(name + "Game Object Click in Progress");
}
}
Was thinking of something like this
somber nacelle
the event system uses either the Graphic Raycaster or Physics Raycaster to raycast from the mouse position and then it can just easily use TryGetComponent or something similar to call the interface methods
shrewd plume
In this case I think it makes sense, but event system has other events that don't necessarily use Graphic Raycaster (I think) like the IMoveHandler and the ISubmitHandler
somber nacelle
the EventSystem also has a reference to the currently selected object so it can easily call TryGetComponent to get the interfaces from the selected object and call the relevant methods
shrewd plume
Yeah, I would want to know some more about it though... its sad to don't really know if this kind of architecture has a name or somethin... 🫠
somber nacelle
there's literally nothing special about it other than what i've already described. the EventSystem uses the Physics Raycaster and/or Graphics Raycaster to get a reference to the object it should call the interface methods on
shrewd plume
I mean to make a system that uses Interfaces to register listenners, but I think this problem has other Middle mans other than just the interfaces. In the two examples that I mentioned there needs some other step for it to work properly, so I don't think it's a easy task
somber nacelle
you're implying that unity is doing something super special to call those methods on the components that implement the interfaces, but that isn't the case. the EventSystem has a reference to the object already so it's as simple as calling TryGetComponent on that reference to call the interface methods
you could use some sort of dependency injection and/or mediator pattern if you want to invoke events and have receivers react to the event without manually getting a reference to subscribe to the event

i dont understand
where am i wrong

does anyone know what the criteria for an object being droppable is? this is in relation to the IDropHandler interface.
like I have an inventory slot gameobject and want to fire the callback every time a UI object is dropped onto it but am unsure if this is correct use case (i think it is but im uncertain).
latent latch
Ah, actually it's this one
https://docs.unity3d.com/2019.1/Documentation/ScriptReference/EventSystems.IDropHandler.html
Haven't played with this stuff for a while
The IEndDrag is actually just fluff which you usually just use to reset displayables
Oh, huh I swear there was a ton more documentation here. Maybe need to revert to the previous version documentations, but the idea is you need both an IDragHandler and an IDropHandler at minimum; everything else is just fluff. I'm pretty sure you can put an IDropHandler without an IDragHandler on your scripts if you just want that gameobject to receive drops callbacks without enabling it to send drag callbacks.
Oh, and the object needs to be able to receive raycasts, so UI stuff needs their raycasts can be blocked box ticked

im using navmesh and when an agent gets close to the destination, it slows down. how do i make it move at the same speed until it hits the destination?
turbid surge
im using navmesh and when an agent gets close to the destination, it slows down....
You need to adjust the agent.StoppingDistance likely
deep willow
okay ill try that
also i want the agent to immediately change direction when the destination changes, because right now it slows, then slowly changes direction
turbid surge
By change direction slowly you mean rotates slowly, right?
turbid surge
try also adjusting the agent.angularSpeed
deep willow
okay
the stopppingDistance didnt change anything
i unticked AutoBraking too to see if that made it work
do i just set them in start method?

yes

you should have autoBraking off and you can set the agent velocity to keep the speed constant

im trying to make a grid, and im using a script, but its getting confused it keeps going back to the beginning after its created a somewhat grid
this is what it makes
heres my code
public class GridScript : MonoBehaviour
{
public float gridSize = 10f;
public float gridSpacing = 1f;
void Start()
{
LineRenderer lineRenderer = GetComponent<LineRenderer>();
int numLines = Mathf.FloorToInt(gridSize / gridSpacing) + 1;
lineRenderer.positionCount = numLines * 2;
float gridStart = -gridSize / 2f;
float gridEnd = gridSize / 2f;
int lineIndex = 0;
for (float i = gridStart; i <= gridEnd; i += gridSpacing)
{
// Add vertical line
lineRenderer.SetPosition(lineIndex, new Vector3(i, gridStart, 0f));
lineIndex++;
lineRenderer.SetPosition(lineIndex, new Vector3(i, gridEnd, 0f));
lineIndex++;
// Add horizontal line
lineRenderer.SetPosition(lineIndex, new Vector3(gridStart, i, 0f));
lineIndex++;
lineRenderer.SetPosition(lineIndex, new Vector3(gridEnd, i, 0f));
lineIndex++;
}
}
}
im assuming its the for loop logic
maybe use a for loop for each vertical and horizontal
quartz folio
You use one line renderer. Line renderers draw one continuous line
civic fern
seperately
so id need to use lets say 2 linerenderers for vertical and horizontal
that makes sense
let me try it rq

hi lads, do know how to wrap around a world map, as in go from one edge to the other seamlessly? In a 2D RPG with tile maps atm. Currently, I have it where you basically have a duplicate map and move it right next to the current one, and they leapfrog each other depending on which edge you go on. I was wondering if theres a better way

Ok on that trigger function, remove the switch because it is going to force the debug to only break when it hits lava from what I see. Have it print when it collides with anything other than the ground
Or when it collides with the box specifically
I assume the only reason it printed lava was because your character fell in there after it already died

Then it likely did. Maybe log the point of contact and use the overloaded second parameter in log to highlight the object in the hierarchy on single click of the log. cs Debug.Log($"...", other.gameObject);

Because your function is doing some switch statement and comparing it to lava

Debug.DrawLine(transform.position, other.transform.position, Color.green, 5.0f);```It's likely the line would be extremely small since the game object and other are touching
Would be the same thing as just following the game objects position every frame
hexed pecan
The line draws between origins, not contact points, so it should be visible
dusk apex
If anything, maybe you're looking at the wrong object - assuming the collider isn't on the skeleton.
lean sail
I believe he said its on an empty object on the skeleton somewhere above
dusk apex
I'm assuming that's where the fault lies.
lean sail
Yea that's why I'm saying to track the game object every frame, I'm thinking it's going flying around very often and falling down the tunnel into the lava very fast
Honestly now that I scrolled up I cant even find where he said that but regardless tracking it every frame will show the fault. It likely is just falling really fast

rather than encrypting it, you would sign it: the server would use a private key to create a digital signature
the game would then only accept your purchases as valid if the signature validates
asymmetric cryptography, rather than symmetric cryptography (the fun is increasing exponentially)
