[chrome wasp]

and then I drag in Gregg rb?

[polar acorn]

what

just drag the object into the variable you already made

[chrome wasp]

ohh the public Rigidbody rb;

[rich adder]

Rigidbody is the component, rbis the name you given it

[chrome wasp]

So I want to drag gregg into that?

[rich adder]

yes if it has a rigidbody

[pastel talon]

also, I tried this but it doesn't work

[rich adder]

first check your Trigger is working. Put Debug.Log in there

[chrome wasp]

I moved dragged Gregg from object into vs code and saved and it didnt do anything

[pastel talon]

The trigger is working because it's doing what it supposed to, except for the particle part

[polar acorn]

The Three Commandments of OnTriggerEnter:

1. Thou Shalt have a 3D Collider on each object
2. Thou Shalt tick isTrigger on at least one of them
3. Thou Shalt have a 3D Rigidbody on at least one of them

[polar acorn]

...what?

[rich adder]

any errors in the console ?

[chrome wasp]

well you said to drag gregg to my variable

OHHHH

WAIT

[rich adder]

in the INSPECTOR

field in the inspector

[chrome wasp]

YEAHHHH

[rich adder]

we've said it like 5 times

[chrome wasp]

ikikikik I just realized

but I do not see it even with public thing

[rich adder]

probably because you have compiler errors

[chrome wasp]

I SEE IT

great ok new issue :/

i have heard this is what programming is like

[warm sleet]

Hello, im programing in unity and I dont know if its possible to make by code that when a missile hits an object, the object break into pieces, I mean, the block is still there but it has less space

[pastel talon]

yeah but it is assigned??

[warm sleet]

An easy example are the bunkers from space invaders

[queen adder]

oof

im goin insane

[chrome wasp]

it still says rb is not assigned but now my gregg is just randomly moving diagonal

when I start the code

[polar acorn]

Whatever Blixtrar was, it no longer exists

[pastel talon]

Swedish lol

[polar acorn]

If it still says it is not assigned, then there exists at least one script where it is not assigned

[rich adder]

ofc its possible. make different sprite states per damage amount

[chrome wasp]

I only have one script

WAIT

thats what I did wrong isnt it

[pastel talon]

yeah for some reason it just unassigns itself when I hit play

[chrome wasp]

Because that script is for moving the character the collision needs its own script?

[polar acorn]

What did you drag into the slot? Is that object ever destroyed?

[rich adder]

no?

what

[chrome wasp]

oh idk

I only have one script tho

[rich adder]

why don't you start showing the current code

don't use screenshots and paste the link

https://hatebin.com

[pastel talon]

It was group and not a single particle system. That's probably the issue right? Because now when I dragged in one of the particle systems it works

[chrome wasp]

https://hatebin.com/gyfdksojrf

[polar acorn]

No idea what you were actually doing with Blixtrar so I can't answer that for sure

but if whatever you did fixed it that was probably the case

[rich adder]

you copied the code from example 10, 0, 10);

this moves it diagonal

[pastel talon]

yeah

thanls

thanks

[chrome wasp]

ohhhhhh

[rich adder]

you have to put back your old direction you had @chrome wasp

[chrome wasp]

with the variables?

[polar acorn]

Well, every frame you're setting the velocity to up-right, that would be why your character is moving up-right

[rich adder]

just replace transform.translate to rb.velocity

all you had to do

direction stayed the same

[chrome wasp]

ohhhhhhh

"The variable rb of Mover has not been assigned.
You probably need to assign the rb variable of the Mover script in the inspector"

So I assumer

I probably need to assign the rb variable of mover script

[rich adder]

bruh

[polar acorn]

You have a Mover that has no rb assigned

[chrome wasp]

in the inspector?

[rich adder]

search inside the hierarchy t:Mover

[warm sleet]

And i only need to program that by Code i Guess, but

[chrome wasp]

gregg came up

[rich adder]

if thats the only one, then greg has Mover with no rb assigned

[warm sleet]

If i need that the barrier breaks in a specific point, because the bullets wont hit always at the same place

[gilded sinew]

guys i could really use help, struggling with dictionary since morning and it doesnt work somehow

[rich adder]

you probably use masks ontop of the hitpoint of bullet and lay that over the sprite

[chrome wasp]

My boy Gregg has the component

[gilded sinew]

i created dictionary in scriptable object.
in game manager script i want to generate new dictionary with data in it

and when i want to print in textmeshpro data from that dictionary it doesnt work

could somebody help me out?

[rich adder]

is this the same object as Greg?

clear the console and hit play

are you sure that error is still there

[chrome wasp]

yeah Gregg is the object I am trying to rb

[chrome wasp]

if you're talking to me everytime I start the game I am flooded with more of that error

[rich adder]

"doesn't work"
this doesn't help.
Start Debugging and giving more info wht that even means

[polar acorn]

Then you have a Mover script that does not have an rb assigned

[chrome wasp]

so do I need to assign the script rb?

cause Gregg has it

and I'm trying to rb Gregg

[polar acorn]

For this Mover script, rb is Gregg's rigidbody

[warm sleet]

Its bad written , is it hammerSlag not hammreSlag?

[polar acorn]

You have another Mover script that has no rb assigned

[rich adder]

can you screenshot hierarchy when you do this

#💻┃code-beginner message

you must def have a copy

[chrome wasp]

is it samplescene? I thought that was just like

a title

[polar acorn]

That's the scene

[twin bolt]

How would i play a sound everytime the time changes, kind of like a clock tick?https://i.imgur.com/RnlYtTV.png

[chrome wasp]

cause it doesnt have an inspector or anything

[polar acorn]

Can you screenshot Gregg's entire inspector

[chrome wasp]

sure

like every drop down arrow expanded?

[polar acorn]

yes

(If they're expanded I can check multiple things at once @rich adder )

[rich adder]

yeah just realized

[polar acorn]

(we don't need them expanded for what I'm pretty sure we're both expecting but there could be a different problem)

[chrome wasp]

This will be several ss

[rich adder]

make sure we see all the components there

[rich adder]

thats fine

[rich adder]

what exactly you need because right now you're not extracting info , you're just printing the text

[chrome wasp]

its in backwards order but yeah

[polar acorn]

You have two Movers

and one of them has no rigidbody

You probably don't want two

[rich adder]

computer never lies 😦

[chrome wasp]

uh ohhh

how do i get rid of of second one

[rich adder]

right click delete ?

[chrome wasp]

iyeyee

[polar acorn]

delete it

[chrome wasp]

got ti

ok the errors are gone

and the posistions are changing on the inspector

but i am not moving

[rich adder]

and did you change the variables to direction

[chrome wasp]

direection?

[rich adder]

yeas

[chrome wasp]

like do I get rid of movespeed and replace w3ith direction??

[summer stump]

Show your current code

Direction was passed into velocity if I read that rollercoaster correctly

[summer stump]

No

[chrome wasp]

https://hatebin.com/ikmcsiurni

[summer stump]

Direction would be the vector giving you the direction of movement. MoveSpeed should be a float you multiply the vector by to modify speed

[rich adder]

ur move speed is 1

in the inspector

might wanna crank that up

[chrome wasp]

ahhhhh

it says my movespeed is 25 in the inspector

[rich adder]

which Mover script did you remove..

[chrome wasp]

that one

but then I put gregg into the other one

[rich adder]

show the gameobject selected, inside the scene

[chrome wasp]

I screenshot gregg in scene?

[rich adder]

ya

[summer stump]

Might wanna remove the deltaTime from your velocity movement
Do
float xValue = Input.GetAxis("Horizontal") * moveSpeed;

Same with zValue

[chrome wasp]

k

[rich adder]

I think Time.deltaTime is fine for consistent move speed

[chrome wasp]

o

[rich adder]

no?

[summer stump]

Velocity is meters per second, so it's already scaled by time. I thought you shouldn't do deltaTime with it

I dunno though

[rich adder]

could be

[chrome wasp]

should I try changing it?

ok i tried changing it

got this "Literal of type double cannot be implicitly converted to type 'float'; use an 'F' suffix to create a literal of this type"

changed it back

annd that is still there

[polar acorn]

decimal numbers need an f at the end to be floats

[rich adder]

you can't write 0.3 you need 0.3f for example in a float field

[chrome wasp]

fixed it

ye

OK SO GOOD NEWS

he moves

only diagonally

i am stupid

i fixed it

IT WORKS

OMG THANK YOU SO MUCH GUYS

EEEEEEE

[rich adder]

[chrome wasp]

I am very sorry I put you through that lol

[polar acorn]

🥳

[chrome wasp]

BUT YES IT WORKS SO WELL!!!!

[rich adder]

hmmweird iirc time.delta time is fine on inputs but it was just to low of a value, I have to use * 10 when I do it on inputs to get consistent speed.
But I don't do it on the rigidbody itself

23 * 0.05 (how much is time.delta time again?) s about 1.15
@summer stump

[summer stump]

One thing to keep in mind that people sometimes dislike:
GetAxis has smoothing.
It will go from 1 to 0 to -1 smoothly, with the decimals between. This can make the player feel "floaty"

If you don't want that "on ice" feeling, use GetAxisRaw, which ONLY return -1, 0, 1 for the values. It snaps to them immediately

But that is for you to test and feel

[chrome wasp]

ah yes I was just testing it and noticed that

hmmmm I think I like the smoothing a bit more

but one more thing

Whenever I manage to flip myself I like float back down

its like there is gravity but it is SO SLOW

[rich adder]

you're overriding gravity

because of .velocity

you need to add .y to the direction

this is a code question how?

[chrome wasp]

what where do i put .y

[rich adder]

inside the velocity

[summer stump]

Where you currently have a 0

[chrome wasp]

ohhhh

[summer stump]

Change that to rb.velocity.y

working much better is there any way to increase gravity

[rich adder]

or make a multiplier

[chrome wasp]

where in project settings?

after this I will give you peace

[rich adder]

its in Edit somewhere

[chrome wasp]

ohhh in physics

got it

[ruby python]

Okay, please don't shout at me but I'm very confused as to what's happening with this little script.

    [SerializeField] Transform referenceObject;
    [SerializeField] Transform solarPanels;

    // Update is called once per frame
    void Update()
    {
        transform.rotation = Quaternion.Euler(0, referenceObject.rotation.y, 0);
        solarPanels.rotation = Quaternion.Euler(referenceObject.rotation.x, 0, 0);
    }

I have an empty which is always pointing at the sun. I'm using that to grab the rotation values and applying them to my solar panel 'post' and the actual panels. I'm very confused, because the rotation on the post works great, but on the panels they don't move.

Does anyone know why when it's pretty much the exact same code please?

[chrome wasp]

ty

[amber spruce]

how do i increase the radius of the character controller

[modest dust]

transform.rotation is a Quaternion, these x and y values aren't euler angles

[short hazel]

.rotation does not contain angles in degrees. Use .eulerAngles

[modest dust]

^

[short hazel]

Quaternions store a rotation on 4 axes (x, y, z, w) with each value ranging from -1 to 1

[rich adder]

the prop that says radius

[amber spruce]

i tried this

characterController.radius += radiusIncreaseAmount;

[rich adder]

uhuh

[ruby python]

Yeah tbh I knew that about Quaternians. Was just very very confused as to why it worked for one, but not the other. lol.

[amber spruce]

public float radiusIncreaseAmount = 0.1f;
private CharacterController characterController;

and this for the variables

[rich adder]

so whats the problem?

[amber spruce]

it doesnt work

[rich adder]

where do you assign character controller @amber spruce

and how you know it doesn't work

[short hazel]

You're lucky it even works for one of the two here

[amber spruce]

would it show the value changing in the inspector

[ruby python]

Well just trying changing to EulerAngles, but VS started shouting at me to use Euler. lol.

[rich adder]

it would if you referenced the correct cc

[short hazel]

I mean referenceObject.eulerAngles.y

[ruby python]

No wait, my fault. lol.

Yeah sorry, brain is minced. lol.

[amber spruce]

i dont think i was assinging the right one lol since i made it private i never dragged in my character controller

[rich adder]

always use the inspector when possible

avoids these issues

[open edge]

Whats best way to learn basic scripts? Is it official Documentation? For example PauseGame standart scripts like stop time exit game or load level?

[rich adder]

https://learn.unity.com/project/beginner-gameplay-scripting

[amber spruce]

how do i get this to work

        radiusIncreaseAmount = Vector3.one * 0.1f;

Error    CS0029    Cannot implicitly convert type 'UnityEngine.Vector3' to 'float'    Assembly-CSharp    C:\Users\vinny\My first game\Assets\movement\CrushObjects.cs    84    Active```

thats what i get

[eternal needle]

A radius is a single number

[amber spruce]

radiusIncreaseAmount is a float btw

[eternal needle]

Multiplying a vector by a number gives you a vector, scaled by that number.

[rich adder]

yes thats why its giving u error

[amber spruce]

how do i set my players radius to Vector3.one * 0.1

cause thats what i set the players scale to

and right now the scale and radius arent the same

[rich adder]

why Vector3.one ?

[amber spruce]

because thats how i get my scale to work how i want it

i dont really remember why i did Vector3.one lol

[rich adder]

you're trying to squeeze 3 numbers in 1

[amber spruce]

did that over a week ago and i ahve a terrible memory

it works for the scale

transform.localScale += Vector3.one * 0.1f;

[rich adder]

thats because scale is not a single number

its a vector3

and you return a vector3

[amber spruce]

so how would i increase my radius by the same amount

because just increasing it by .1 doesnt work

[rich adder]

thats the same as doing 1 * 0.1 3 times (0.1, 0.1, 0.1)

[polar acorn]

why not

[amber spruce]

idk the collider is way to big

[rich adder]

so make the value smaller?

[amber spruce]

so can i just set it to .001

[amber spruce]

ik but to get it to the exact right number is gonna be hard

i want the collider to be the same size as the model thing

[rich adder]

so use the scale magnitude of the object or something

hard to say idk what ur situation looks like

[amber spruce]

well if i set it to the exact scale then its wrong

[rich adder]

scale.magnitude * sumnumber

hard to do it by scale alone but you're not giving much to on 🤷‍♂️ lol

[amber spruce]

i think i got it its a little big but it should work

[rich adder]

oh you wanted it bigger

[amber spruce]

yeah my game is about eating all the objects to get bigger

you eat them by colliding with them

[rich adder]

gotcha

think I remember this a few days ago

[amber spruce]

although it seems to already increase it with the size so not sure why its not working right

i wonder if its because its a circle

should i be using like a box collider or smth

because when you get big enough it gets really hard to eat small objects

[gray bough]

Does anyone mind helping me getting a button on my scene to work? I have read a lot of tutorial articles and watched a lot of videos and I'm not sure why it's not working. I'm working in a 2D setting

[wintry quarry]

#📲┃ui-ux if you mean a UI button

[silk night]

Do you have

• EventSystem in your scene?
• Graphic Raycaster on your canvas?

[gray bough]

eventSystem yes graphic raycaster no. What does the graphic raycaster do?

[silk night]

makes elements on the canvas clickable

[amber spruce]

how do i have the character controller use a box collider

You don't, character controllers are capsule-shaped

[amber spruce]

dang

[ruby python]

Okay, well I'm losing the will to live. lol.

Sorry, I know this should be really simple stuff but I just seriously don't understand what's going on.

    [SerializeField] Transform referenceObject;
    [SerializeField] Transform solarPanels;

    // Update is called once per frame
    void Update()
    {
        transform.localRotation = Quaternion.Euler(0, referenceObject.eulerAngles.y, 0);
        solarPanels.rotation = Quaternion.Euler(referenceObject.eulerAngles.x + 90f, 0, 0);
    }

Everything is pretty much working as it should be except for the Z axis on the Solar Panel Rotation, it should stay at its local 0, but it just doesn't. I've tried setting the solarPanels to localrotation, but if I do that, then nothing works. The 'pole' object works perfectly though.

Actually, scratch that, sorry, the pole item isn't working, it doesn't rotate on the y as it should when set to local

[silk night]

try the LookAt function

you want the items to look at a reference object or have the same rotation as the reference?

[wintry quarry]

what is this code supposed to be doing?

[ruby python]

Same rotation as the reference. The reference is using LookAt to look at the sun, the solar panels are split into two object, one that 'spins' around it's Y axis, and the actual panels that spin around their X axis.

[wintry quarry]

Also using isolated euler angles from a transform like that is usually not going to work well

[ruby python]

Trying to get these panels to always point at the sun object I have in the scene.

OH!!! I just figured it out. lol.

[SerializeField] Transform referenceObject;
    [SerializeField] Transform solarPanels;

    // Update is called once per frame
    void Update()
    {
        transform.localRotation = Quaternion.Euler(0f, referenceObject.localEulerAngles.y, 0f);
        solarPanels.localRotation = Quaternion.Euler(referenceObject.localEulerAngles.x + 90f, 0f, 0f);
    }

Needed to grab the localEulerAngles from the reference object.

[amber spruce]

so how would i fix collisions being messed up

when you get big enough the only way to colide with stuff is by the very bottom touching it which isnt very big of a area

[rich adder]

while you increase radius you have to increase height

[amber spruce]

that doesnt work because now i just fall through the map

[rich adder]

nvm then...probably because center needs to be moved when you mess with height..

[amber spruce]

and its still only that little bit that hits the ground

[rich adder]

oh so you don't want the capsule shape ?

[amber spruce]

no because it messes with collisions

[rich adder]

then don't use CC

[amber spruce]

dont i have to make a custom one for movement then

or no

does that deal with movement?

[rich adder]

do u want a box or sphere?

yes use a rigidbody with sphere / box w.e shape u want

[amber spruce]

ok thanks

[rich adder]

what does "mess with collision" mean just curious

[amber spruce]

like its hard to actually collide with smaller objects

if your big enough it becomes impossible

[rich adder]

you could potentially have two colliders

a box at the bottom or something

it wont sync up with cc tho

[silk night]

if you have the possiblity, make all objects you want to eat collider very high so it is easyily touched by the cylinder part

for your game you could even use 2d collision and just make the visuals 3d

[fluid crane]

Hello guys, anyone can help me with a question, i have a UI Image in my game and i want to make a glow effect behind it from a color that variate depending on the rarity.

What is the best practice to replicate that in unity?

Image as example attached.

[amber spruce]

yeah but then wont it mess with the position wont the player be on top of them

[silk night]

not if you destroy them on touch

[silk night]

Look for (2d) outline shaders

[azure zenith]

Is there a way to explode a throwable when it lands on the floor?

I am supposed to do it in a method with no parameters allowed

[polar acorn]

Yes

[silk night]

Destroy it on collision enter and play a particle effect

[amber spruce]

rn im using a mesh collider should i use smth else

[silk night]

Depending on the shape of the object box collider is the easiest

[amber spruce]

so i have trees and stuff

and houses

rocks etc

[amber spruce]

is there a way to have the box collider auto size to it

because i have tons of objects

[silk night]

depending on how detailed it needs to be just roughly estimate the shapes with cylinders, box colliders and so on

[fluid crane]

Like this u mean?

[silk night]

i think box colliders auto size to a mesh if you put it on them

[silk night]

I think theres some with better functionality online

[azure zenith]

That is what I wanted to do but I am supposed to do it in a method they have given me with no parameters so... Idk

[amber spruce]

yeah but now i cant change the size for them all at once sad

[silk night]

I dont get what you mean

[silk night]

If you change the object directly the colliders will scale with it

[amber spruce]

yeah but i cant do that to all of them at once

i have to do it for each one

[dreamy ingot]

Is it possible to pass in a script to another script without using the scripts name as its variable type?
Instead of doing "public jumpController playerJumpController" is it possible to have a generic script type or something like that?
I'm trying to build a framework for the generation of magic spells modeled after D&D 5e's spells via scriptable objects where you can simply drag in a
procreated spell functionality in a provided script or create your own script to use for its mechanics.

[silk night]

Create a parent interface for all scripts you want to assign

[polar acorn]

You should have a shared type that all the spells have in common and make the variable of that type

Hi im having a problem with null reference exceptions for some gameobjects that are reference in a list that are assigned in the inspector and it is only these object sand even if they arent in a list the same issue is happening the relevent code is ```cs private void RPMLightsMovement() //controlls which light should be on
{
rpm = controller.RPM;
float closest = GetRPMClosest(rpm);
RPMLightsDict[closest].On();
List<float> ramaingVals = new List<float>();
foreach (float val in RPMLightsVals)
{
if (val > closest)
{
ramaingVals.Add(val);
}
}
foreach (float val in ramaingVals)
{
RPMLightsDict[val].Off();
}
}

private void PopSliderVals(float mRPM) //uses maths to work out a value at which each light should be used and then adds that as a key and the game object as a value in a dictionary
{
float interval = (0 - mRPM) / (RPMLights.Count - 1);
for (int i = 0; i < RPMLights.Count; i++)
{
RPMLightsVals.Add(mRPM + (i * interval));
}
RPMLightsVals.Reverse();
for (int i = 0; i < RPMLights.Count; i++)
{
RPMLightsDict.Add(RPMLightsVals[i], RPMLights[i]);
}
}

Any help is apreciated

[polar acorn]

What line is the error

[uncut veldt]

line 5 RPMLightsDict[closest].On() and line 29 RPMLightsDict.Add(RPMLightsVals[i], RPMLights[i]) its whenever i access the gameobject or the script i have attatch to said gameobject to try and fix this error

[languid spire]

RPMLightsDict not initialised?

[polar acorn]

For the first: Either RPMLightsDict is null, or RPMLightsDict[closest] is null
Second: Either RPMLightsDict, RPMLightsVals, RPMLights, RPMLightsVals[i], or RPMLights[i] is null

Try logging some values to see which one it is

[uncut veldt]

so the error is first triggered with line 29 and then the line 5 error is triggered every frame after start as it is called every frame so it is not reading the objects even though they are assigned

[polar acorn]

So, if the line 29 one is first, let me ammend:

For the first: Either RPMLightsDict, RPMLightsVals, RPMLights, RPMLightsVals[i], or RPMLights[i] is null
Second: Either RPMLightsDict is null, or RPMLightsDict[closest] is null

[ivory bobcat]

Did you verify if they are null?

[uncut veldt]

so i know that the RPMLightsVals is not null as that work when i was using a slider and the RPMLights reading null causes the dict to be null

[polar acorn]

Instead of guessing, check

Log some values, find out which is null

[edgy prism]

Hello I am having a bit of trouble with my coroutine so, when I have choices canContinue is false I want to be able to select my choices then continue with the first bit of code

while(story.canContinue)
        {
            var currentLine = story.Continue();
            AudioManager.i.PlaySfx(AudioId.UISelect);
            yield return TypeDialog(currentLine);
            yield return new WaitUntil(() => Input.GetKeyDown(KeyCode.Z) || Input.touchCount > 0);
        }

        if (story.currentChoices.Count != 0)
        {
            yield return choiceBox.ShowDialogChoices(story, onChoiceSelected);
        }

[uncut veldt]

no i havent got verification currently as even if they are i have tried assigning them through code and it still doesnt work so i have no way to rectifiy it even if it does chatch it

[polar acorn]

Then you would probably need to start a new coroutine. Once canContinue is false, the while loop ends

[ivory bobcat]

You'd verify it at runtime. And if they are null, determine why or how to make them not null.

[polar acorn]

Before you attempt any sort of debugging or problem solving, find out what the problem is

[ivory bobcat]

I can't really debug for you because the project is in front of you and not me.

[polar acorn]

Either log the values or step through with the debugger to find out what is null

[edgy prism]

Ah thats frustrating I know the purpose of the coroutine is that it executes in order but is there no way for me to say oop go back?

[polar acorn]

Start another one

[edgy prism]

Ok thanks for your help ill do it like this then

Hey I've made a grappling hook in my game. So I can shoot it and it enables a SpringJoint2D between my player and the grapple head.
As you can see in the video it does really unnatural movements. It looks like the Spring tries to pull the player towards the right or the left of itself and not in the direction of the player.

so i have added this statement to debug Debug.Log(string.Concat("Light ", i, " reading ", RPMLights[i].gameObject.name)); which when i run it it shows that the light is there and the name is correct however after the first ittereation in the for loop the null reference error is thrown maybe the update function is called while the dict is getting populated so it cant find the light but if that is the case i didnt think update got called before start had finished

[ivory bobcat]

Doesn't look related to code. Try #💻┃unity-talk

[gilded sinew]

@rich adder u have nice tutorials

[polar acorn]

These are the things that can be null on your lines.
#💻┃code-beginner message

Log them, in that order, in separate logs, before the lines that throw the errors.

Find the one that is blank, or the last one before an error occurs

and see which variable is null

[ivory bobcat]

Just log before the error line to see what's null - simple as that. If there's some confusion about how to properly log, you may want to ask.

[uncut veldt]

okay will do

[gilded sinew]

guys for some reason i cant fill my dictionary from loop. i tried lots of stuff. only if i add pair manually it worked. can somebody help me out why code above doesnt work? the line that i highlited code somehow doesnt reach it otherwise i would get pairs created in dictionary

[ivory bobcat]

Log to see if it has reached it.

[gilded sinew]

how to do that 🙂

[rich adder]

use Debug.Log

[polar acorn]

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

[gilded sinew]

oh right i forgot about that

ty guys

ill test it now

since morning trying to figure out why it doesnt work

[ivory bobcat]

The assumption was that it doesn't reach that line of code. Verify it.

[gilded sinew]

yes, trying now

yep it doesnt reach it. not getting any messages when i run it

[ivory bobcat]

So maybe tile game object is always null

[gilded sinew]

i guess that means that tileGameObject is = null somehow

yeah not sure how tho

[ivory bobcat]

Or none of these statements are ever processed.

[uncut veldt]

So i figured out what it was so the lights werent null nore were the vals it was the dict as i had no instantiation only just decleration of the veriable so it was adding to a dict that didnt exist thanks for your help

[gilded sinew]

no some are bcs i used log thingy above to check if loops is running and it did

[ivory bobcat]

Well then https://docs.unity3d.com/ScriptReference/Tilemaps.Tilemap.GetInstantiatedObject.html we're to assume that there aren't any objects at said position.

[gilded sinew]

yeah but tilemap is filled with tiles

[ivory bobcat]

That wasn't what the line of code saw/thought/said.

[gilded sinew]

yep

[rich adder]

are you sure those are cells positions you're passing and not World Positions?

iirc might need https://docs.unity3d.com/ScriptReference/GridLayout.WorldToCell.html

[gilded sinew]

hmmm good point

but i tried for 0 0 0 and tile on that spot still didnt get result i wanted (when i open it some stuff should happen confirming that tile has data assigned to it via dictionary)

[rich adder]

wdym?

[gilded sinew]

i have a tile on map with coordinates 0 0 0 and even on that one dictionary hasnt created pair (data for it for that position)

i think that no mater what cell position i am passing at least that one should work since world position and cell position match there or i am thinking wrong

[rich adder]

what you see in the inspector is not neceserraily the 00 for tilemap

tilemap i think starts from bottom left of the screen

grid has its own system

[gilded sinew]

hmm idk i used TMP in canvas to display coordinates on clicked tile and 0 0 0 is in center of my tilemap

[rich adder]

how do you know u hit the tilemap ?

[gilded sinew]

using ray that detects tile i am touching

then extracting coordinates of that tile

[cobalt granite]

If I have multiple weapons how do I keep track of which kind I have equipped so I know which animations to play?

[wintry quarry]

with a variable

currentlyEquippedWeapon

[cobalt granite]

right but should I just be like constantly checking for what object I have equipped or is there a more efficient way to do that?

[rich adder]

are you using world to cell ?
Yellow is mouse click, Pink is WorldToCell yellow pos

 Gizmos.color = Color.yellow;
        Gizmos.DrawSphere(mouseClick, 0.23f);
        Gizmos.color = Color.magenta;
        Gizmos.DrawSphere(grid.WorldToCell(mouseClick), 0.13f);```

[gilded sinew]

i see what you mean and its possible solution but i dont know how to rewrite that line so i get gameobjects back instead of null

this is returning null somehow

tested with debug.log and that is the problem that line. just dont know how to fix it

[rich adder]

I think this only gets the GameObject that a tile might have spawned

[gilded sinew]

ok go on

[rich adder]

not 100% never used that function

[gilded sinew]

ok how to get game object from that position?

[rich adder]

I think its because tiles , technically arent gameobject

just a data representation of something there with a sprite

[gilded sinew]

hmm but when u make them on map they show as separate game objects

[rich adder]

i thought it was for this

[gilded sinew]

i see

[rich adder]

doc mentions only Scriptable Tiles 🤷‍♂️ i guess it has to do with that

[gilded sinew]

aight ty bud. trying different aproach now if that doesnt work then i have to think of something else.

good thing is we know what line is issue

[rich adder]

maybe try getting the tile and do .gameObject ?

or I think this is the same thing
https://docs.unity3d.com/ScriptReference/Tilemaps.Tile-gameObject.html

the doc doesn't clarify

[rich adder]

what do you need to do specifically with the tiles/gameobject

[gilded sinew]

i want to extract tile tag

thats the main and only purpose

tile tag/ game object tag

[rich adder]

the tile has no tag tho

not sure what u mean

[gilded sinew]

then i need game object tag

lemi show you

no wait

[rich adder]

so this isn't a tilemap object

[chrome wasp]

dammit im back again

[gilded sinew]

i meant

bellow

[rich adder]

I get it

[chrome wasp]

Jesus how long have you been helping

[gilded sinew]

tag Water

[rich adder]

but this isn't a Tile

this is a gameobject

nothing to do with tilemap

[gilded sinew]

then why does code above not work

[rich adder]

because its not part of the tilemap?

[gilded sinew]

shouldnt c# show error then

[rich adder]

bruh its literally null

hence ur if statement not hitting

there is no error if u dont try to use something null

[gilded sinew]

okay okay

i see

[rich adder]

just get it how you would get any other gameobject

[gilded sinew]

how do i fix that to get god damn tag bro

i cant think anymore been struggling with this since morning

[rich adder]

how do you want to get object? with a raycast ?

[gilded sinew]

yeah

[rich adder]

collider.gameObject.tag

[gilded sinew]

jesus i think i know what u mean

[chrome wasp]

my gravity is weird and idk how to fix it

[gilded sinew]

navarone u are boss

[chrome wasp]

its like no matter what I put it at I still fall slow

[chrome wasp]

fr navarone helped me so much earlier

[rich adder]

show current script

[rich adder]

did you fix ?

[gilded sinew]

i am speechless.

[gilded sinew]

working on it now but 99% sure i know what u mean

[chrome wasp]

I was editing it in project settings but I googled it and put in some code, I'll send the code

https://hatebin.com/dzbbjbnnqw

[rich adder]

what happen to the :OhNo emoji..

[chrome wasp]

Last two lines

[rich adder]

this is hella wrong

yValue

this is supposed to be your rigidbody.velocity.y

or a multiplied version f it

[chrome wasp]

I changed it cause jump

oh wait

i just realized

changing it back

[rich adder]

also gravity x ?

[chrome wasp]

now i cannot jump

[rich adder]

forgot how to do jump with .velocity but you have to add onto the current value

then pass that inside Y

[chrome wasp]

what where when am i adding onto w

"So firstly he’s already got a Y velocity that you are just overwriting 🙂 Hence the weirdness… You could add something to his velocity: rigidbody.velocity = rigidbody.velocity + Vector3.up * 2; Or you are probably better adding a force: rigidbody.AddForce(0,10,0); Bear in mind that rigidbodies…" found that in google

rigidbody.velocity = rigidbody.velocity + Vector3.up * 2;

Can I use that

[rich adder]

are you reading this https://gamedevbeginner.com/how-to-jump-in-unity-with-or-without-physics/

or is that unity answer

[chrome wasp]

its a unity answer

https://discussions.unity.com/t/getting-rigidbody-to-jump-by-changing-the-velocity/43363

[rich adder]

i usually use addforce but u can give it a try, since addforce wont work with .vel

[chrome wasp]

error

"'Component' does not contain a definition for 'velocity' and no accessible extension method 'velocity' accepting a first argument of type 'Component' could be found (are you missing a using directive or an assembly reference?)"

so my code

doesnt know what velocity is?

[heady nimbus]

your reference is rb based on your original post

[rich adder]

told you this error alone doesnt say anything

show the line u changed

[chrome wasp]

I added the if statement

[heady nimbus]

you want rb.velocity += Vector3.up * 2

[chrome wasp]

wowahahhh

[chrome wasp]

ok that did SOMETHING

my guy just kinda

flew

[rich adder]

because ur constantly adding

to itself

think you need to do in some sort of button press

[chrome wasp]

oh right

for the jump button press

[chrome wasp]

btw how do i do that

with the grey

[heady nimbus]

surround it with the backtick `

[chrome wasp]

(Input.GetButtonDown ("Jump"))

so I need that

[chrome wasp]

along with this

[heady nimbus]

Yes, and you'll also need a ground check so that you can't keep pressing jump while in the air. That part is a little bit more complicated

[chrome wasp]

that was going to be my next quetion but ima take this one step at a time

[upper spire]

how can i determine the material of the face a physics.checksphere hit?

[chrome wasp]

if (Input.GetButtonDown ("Jump")) { rb.velocity += Vector3.up * 2; }

I have added that code

and there are no errors but I cannot jump

[upper spire]

you could always try addforce

[chrome wasp]

would the code I wrote out work in theory? Like did I use an if statement right?

[chrome wasp]

where do i plonk it in

[heady nimbus]

I don't think it's the velocity assignment. Your button press looks wrong, but I'm not sure if you're doing a controller input or something that I"m not used to?

Mine usually looks like Input.GetKeyDown(KeyCode.Space)

[upper spire]

something like

rb.AddForce(Vector3.up * 2, ForceMode.Impulse);

you can also try swap out your getbuttondown for a getkey then use keycode.space or something just to test the input detection

[rich adder]

addforce doesnt work when u use.velocity

[chrome wasp]

hm ok

[rich adder]

show current script recent

[heady nimbus]

Yea, AddForce and velocity are different ways to move

[chrome wasp]

https://hatebin.com/sqhzgujiqv

[chrome wasp]

So for the alternate option I could just sawp getbuttondown for getkey? And then google how to use keycode space?

[upper spire]

it would just be

Input.GetKey(Keycode.Space)

[chrome wasp]

oh okay

[silver zenith]

you could consider adding in a debug.log to see if the button is even registering

[upper spire]

or input.getkeydown if you only want it to enable for 1 frame after clicking

[heady nimbus]

Well as far as I know, GetButton is usually for controllers

[upper spire]

[silver zenith]

Debug.log ("some message")

add it in the if statement

and then test jump to see if message prints

in console

[rich adder]

  if (Input.GetKeyDown(KeyCode.Space))
        {
            var vel = rb.velocity;
            vel.y += 10;
            rb.velocity = vel;
        }```

try this

[chrome wasp]

I THINK IT WORKS

[gilded sinew]

SOLVED

TYYYYYYYYYYY

[chrome wasp]

why is it that sometimes if i go high enough up I just fall through my plane?

[gilded sinew]

this fixed my problem

[rich adder]

nice

[gilded sinew]

ty bro, legit 8 hours sturggling with this stuff

[rich adder]

try turning the collision to continious mode

[gilded sinew]

[acoustic arch]

https://hatebin.com/dqolilyvmg and https://hatebin.com/eehnwiuzwv

i get an error

[gilded sinew]

dont want to experiment and lose another 8 hours

[acoustic arch]

saying instance on set to object on line 22

for the 1st code

[chrome wasp]

Fixed!!

Okay final issue

I can just double jump infinite times

[gilded sinew]

oh wait that was meant for lilith lol

@chrome wasp i guess its our lucky day

[chrome wasp]

lol

[rich adder]

you need a grounded check

[heady nimbus]

Suggestions on the best way to have an enemy ai detect the edge of a platform, reverse direction, collide with an opposite wall and reverse again? (Basically just like 3-4 different collision checks?)

[rich adder]

eg Physics.Raycast or Physics.Spherecasst etc.

[rich adder]

oh speaking of which

maybe raycasts

[heady nimbus]

BoxCast has been my go to way for ground checks recently

[chrome wasp]

and how do I...

box/ray/sphere cast

[rich adder]

any tutorial that shows grounded check will show

[chrome wasp]

k

[heady nimbus]

So I've got a raycast that I've set to originate from the front edge and point down, which seems to be handling the "edge of platform" scenario, but I'm having trouble getting the raycast to flip sides when the sprite flips. I don't know if I need to set up like 4 different ray casts to detect in every direction basically?

[heady nimbus]

Yea, this is definitely something you should do some google research on. Raycasts are super easy once you understand them and hugely useful. Worth learning for any project

[rich adder]

ohh you only flipsprites and not rotate player itself ? i suppose in that case u would need then ray for all directions

[heady nimbus]

Well I mean right now the sprite is just the default square that I reverse the localScale.x for

[rich adder]

topdown or side view?

[heady nimbus]

Side

[rich adder]

I tend to rotate object on the Y axis

[chrome wasp]

I'm gonna go learn c# then come back to this

or at least the basics

get an understanding of it

[heady nimbus]

That's a good start

[mild mortar]

I'm trying to learn how to use the new input system and so I was changing a bit of my code.

What's the ideal method for moving the player character?
I was using transform.Translate originally but the movement is odd since it just stops completely when I let go of a button, instead of slowing down in a more realistic way, but then somewhere I think someone mentioned to try using AddForce. But now my character just falls over on the spot when I press a key instead.

[heady nimbus]

yea, I think that was my next attempt

[acoustic arch]

hey how can i make 2 gameobjects the exact same, like to have the hotbar slots in my inventory change with the ones on the screen?

and what would it be called btw

[heady nimbus]

You need to check the constrains on your rigid body if it's falling over with force

This is for 2D obviously, but just check the appropriate freeze rotations and it shouldn't fall over

[mild mortar]

Yeah it's 3d that I'm working with. Now that I've frozen rotation, I can see that he doesn't actually move at all when I push a key, so just trying to figure out what's going on

[heady nimbus]

Modify your force values, 5 might not be enough if that's what you were using with translate? They're 2 very different systems

[rich adder]

Dont mulitply rigidbody with Time.delta time

[mild mortar]

Sure I'll give that a try

Just to check then, is AddForce actually the generally recommended way for having movement on a character?

And the other thing I was meaning to ask is, is locking the rotation not a proper fix for this? As I figured it is gonna cause a problem for me when I want the character to turn while running if holding W & D for instance

I'm brand new to Unity so sorry if it's a stupid questions

[heady nimbus]

Oh yup, I missed that. You don't want delta time when adding force or velocity

[silk night]

If you want very physics based movement - yes, otherwise you can use MovePosition

It generally behaves a bit different and you will have different problems with each of them that you need to solve, but its not a question about what should you do, but more about what you want to do

[eternal needle]

Theres 2 types of movement, rigidbody and just moving the transform. Rigidbody is useful if you want it to respect physics and react appropriately to getting hit for example. It is also extremely tedious to get one to move exactly how you want in comparison to moving the transform.
Moving the transform is much more tedious in getting it to not go through walls

MovePosition on a kinematic rb is also the same as just moving the transform position. It just does extra stuff like give it a velocity during the move

[heady nimbus]

You don't want to lock ALL the rotations. Just the axis that makes them fall over. Y axis should still be unlocked so you can rotate in place

[mild mortar]

Yeah it's definitely more useful physics wise as I just want to make a sort of platformer at the moment with large objects etc that swing and knock you off etc

[eternal needle]

You can still rotate it by locking all axis. That locking only stops it from rotating due to physics

But it can also cause somewhat weird interactions. You can see this by locking position and throwing an object at it

Instead of locking all rotations, you could constantly apply torque to get it towards the rotation you want

[wintry harbor]

Someone please help me. In my scene, I have an array of players gathered by using FindObjectsWithTag("Player"). I want each player in my scene to have a unique number (1-8). I've tried accomplishing this via lists and dictionaries, but whenever I do, I get the error "index is out of bounds". Is there a better way to go about doing this?

tl;dr I want to create a list of player objects each with a unique number attached to them (1-8).

[formal escarp]

I have a question about coding. I was told that the code is different for 2D projects and 3D. But how much different? Even the movement? Is there any place where i can read about code for 2D? (2D Similar to Enter the Gungeon, Dont starve or games like this?)

[eternal needle]

Add debugs like how large the array is. You are trying to access an element that doesnt exist.

[mild mortar]

Hmm I see

It's a lot to wrap my head around. I tried using the "Starter Assets - Third Person Character Controller" asset recently, that's actually exactly what I want as the character moves, rotates and such in a proper way.

My goal is to get to that point atm, but I want to try to do it myself and learn rather then import theirs

[heady nimbus]

I mean it's different in the sense that you're working mostly in Vector2 vs Vector3, and for physics and colliders most of the 2D stuff is appended as 2D, like BoxCollider2D

[polar acorn]

Physics is different in 2D and 3D, and that's basically it

[summer stump]

As bawsi said, and you were told yesterday, debug it.
The data structure you use is irrelevant to this issue.
Doesn't matter if it's an array, list, or whatever.

[wintry harbor]

Debug.Log?

[summer stump]

Yep

That is one way for sure

[heady nimbus]

Oops... Lol

[formal escarp]

Is just that? A physics thing? do you guys think 2D is easier than 3D? (Again .I mean games like Cult of the lamb, dont starve, etc) the only thing i can think of is when i used to use GameMaker or similar for 2D games and i would just put invisible blocks for not getting out of bounds.

[rich adder]

I find 2D harder because the assets are harder to work without an artist

[wintry harbor]

I have something like that. I have the number of players in the scene in an integer variable, and it displays in the log the number of players in the scene. But it doesn't keep track of each individual player, just the number of players.

[rich adder]

the code is exactly the same mostly @formal escarp

[formal escarp]

Do you guys have any link i can read talking about how to start stuff like a bullet hell? i hope i am not being annoying.

[rich adder]

the logic all that is the same

[polar acorn]

It really doesn't matter much

[heady nimbus]

I mean both are suitable for different things. It depends on what you want to do. Some ideas will be easier in 2D some harder

[formal escarp]

Well. I care about making it work. For example, for college we had to give today a 3D thingy where character should be able to jump, use raycast to kill enemies, make stuff move etc. but the visuals did not matter so eveything was a cube or spheres. Can you do the same tho right? For 2D.

[formal escarp]

Bullet hell game.

btw i failed my exam today. I spent all week coding but before we gave that to teacher we had to take a exam and i got 8/15. and you needed 9/15. so teacher wont even look at my prototype of game. 💀

[silk night]

If you really do not care if its 2 or 3d, a 2d game saves you a lot of trouble in different scenarios

[rich adder]

I suppose you can use placehooler srpites sure

3D is just easier to work with esp if you're not particularly good at drawing

[heady nimbus]

I don't reeally think it's the genre that matters, but what specifically you're trying to accomplish.

[formal escarp]

I mainly care about mechanics working.

[timber tide]

sculpt tool actually pretty easy to use in blender, but for the life of me I can't draw 2D

[summer stump]

Do you debug the data structure itself? Like the number of items in it, the length or count (are you using a list or array right now)?

[heady nimbus]

There's assets for everything. I'm a horrible artist, I use place holders for basically everything. I just like making mechanical projects. Lol

[formal escarp]

Just a prototype. like, being able to move enemies shooting stuff at you, etc. something simple so i can start from scratch.

[rich adder]

in 2D sucks, when you want to add sprites from asset pack they look completely different from another asset pack

3D more or less has 2 style

sylized/Lowpoly and Realisitic

[silk night]

No thats absolutely not true, different 3d packs can look horrible together even if in the same style

[heady nimbus]

That's going to happen if you're using assets from differnet packs in 3d too though.

[rich adder]

thats because the textures

but those are easier to change

[formal escarp]

btw im a bit sad i failed the exam man. i was 1 question away from going thru.

[timber tide]

wake up call to study more

[silk night]

Perspective, attention to detail, scale of details to each other, topography, all of them can ruin the look

[rich adder]

yeah I mean art direction is everything, but just saying 3D is easier to blend together than 2D

[eternal sage]

can anyone help me with an issue im having in unity?

[formal escarp]

im going to take my face off.

[heady nimbus]

Yea, like I said i"m not an artist, but I'd much rather work on 2D assets then 3d. Lol

[rich adder]

https://dontasktoask.com

[heady nimbus]

beat me to it

[formal escarp]

but at least now i know some of the basics. how to move, raycast and how it works, how to make jump and platafforms move, etc.

[rich adder]

take one thing at a time

[formal escarp]

i think its a great start. a month ago i did not know how to anything of this.

[eternal sage]

well i cant really explain the problem thats the issue

[formal escarp]

I know how to do that on 3D tho.

[heady nimbus]

We can't help if you can't tell us what's wrong. Lol

[formal escarp]

anyways. thanks guys. ill go and try to find anything that i can read that it tells me how to start bullet hell 2D.

[rich adder]

if you can't explain it you won't ever solve it 🙂

[gilded sinew]

i have small issue cant figure out why. Using function to convert cell to world position and one coordinate is converting properly but other isnt. z is converting good but x isnt.

[rich adder]

how can we help to something you cannot explain @eternal sage

[heady nimbus]

Too high level. Think of it in smaller pieces. Don't think "how to make a bullet hell" think about what are the core mechanics that make up a bullet hell and start learning each of them individually

[gilded sinew]

method that is converting cell to world position. not sure how one is converting properly but other isnt

[rich adder]

why are u still using tilemap function lol you dont have a tilemap

[formal escarp]

Like, how characters shoot at the CURRENT position of the player for example but to make the bullet not follow them? but rather detect "oh. player on X25 Y30 Z8 i shoot that position"? i think you are right. i learn mechanics.

[polar acorn]

You forgot a semicolon on line 17

[gilded sinew]

just to convert its position to world, because i need to pair cell position with object data and for object data and its access via ray i need world position

[formal escarp]

and how to move i guess. i am not even sure if the code of moving on 3D and 2D is the same but im guessing no because of the Vectors as previously said.

[heady nimbus]

Exactly, that's 1 small piece you can work on, but it is a big mechanic of a bullet hell. Figuring that out will help you with a lot of the other pieces as well

[polar acorn]

Tilemap.GetCellCenterWorld will get you the tile at that position of a tilemap. Do you have a tilemap you are trying to get the grid position of

[eternal sage]

well im new to programming and unity altogether, and im trying to make something duplicate. Im only trying to make it clone once but it does it untill my unity crashes.

[formal escarp]

okie dokie. i think i should start with the easier mechanics first so i can learn, test, learn, test, learn test. thanks

[gilded sinew]

yes bud @polar acorn and its x minimum is -14 cell position and world position of that tile is -14.something and when converting i am getting -11.something or -12.something

[heady nimbus]

Sounds like you've just got it in a loop with no way out (exit condition). I'm assuming you have it in the Update method then

[polar acorn]

Does the object you are cloning contain the code that clones the object

[swift crag]

I have a plain-old C# class that I want to be able to log an error from. I want to log something that helps me find the offending class (it's always going to be serialized on a component somewhere).

Any idea how I can do that? Obviously I can't just log this, 'cos this thing isn't a unity object.

Perhaps I should just hand it a reference to the component it's a part of.

[heady nimbus]

Ohhh, or that... I alwys forget that one. Haha

[polar acorn]

can you show the inspector of your tilemap

[polar acorn]

And it's populated, right? You've got tiles in all the positions you're expecting to get?

[gilded sinew]

yeah its populated but u did point me out one thing that could be issue for something else, tho it still doesnt explain why vallue is not matching for one axis but is for other

[tame mist]

hello, I'm struggling to figure out why my code is having an issue passing a gameObject reference from one script to the other.

The currentCar gameObject is initially set as the cars driver door but I assign it as the actual parent car gameObject with the transform.parent.parent... code.

the log statement shows it's the instantiated prefab gameObject, but for some reason my code is having an issue passing it to another script that needs the reference.

// CarRadialMenuManager Script
private void SendCarToMechanic()
{
    currentCar.GetComponent<DriveCar>().ExitVehicle();

    currentCar = currentCar.gameObject.transform.parent.parent.parent.parent.gameObject;

    Debug.Log("currentCar = " + currentCar);

    // this line below is giving the NullReferenceException
    mechanicController.AddCarToList(currentCar);
}

//MechanicController script
public void AddCarToList(GameObject car)
{
    carList.Add(car);
}

[polar acorn]

What is line 132 of CarRadialMenuManager.cs

[gilded sinew]

i figured the issue. ty for pointing some stuff out it indirectly helped

[tame mist]

mechanicController.AddCarToList(currentCar);

[polar acorn]

mechanicController is null

[tame mist]

oh wow, you're right I forgot to assign the reference in the inspector 🙃

[gilded sinew]

after 10 hours i completely fixed my problems

ty all that helped

[rich adder]

huh what was it ?

[cobalt granite]

https://gdl.space/hequxatoqa.cs

So I have this script that uses animation key events to run most of the methods and I'm planning on adding a bunch of other spells other than fireball, but I want to know if I'm doing something like super wrong and it'll bite me in the ass later on

[rich adder]

keep track of the weapon/spell type in script , then you could only ever need 1 method to call to fire

they can even be scriptable objects that have their own methods

just swap out the asset and run its Fire method

[cobalt granite]

Yeah I was going to make a simple GUI that with button presses 1 2 and 3 will select which spell it is using, but I just wanted to make sure it seemed like scalable I guess. Like I've never really gone too big with games so idk if adding like even 30 different kinds of spells would be a ton

[rich adder]

with SO it wouldn't be

with enum 30 is a lot

[cobalt granite]

SO?

[rich adder]

ScriptableObject

its a class as an asset

more or less

they just goated to create variations of something

[cobalt granite]

so having a list of a ton of spell strings wouldn't be good?

I'll look into all of that

[rich adder]

I mean you could do some type of dictionary look up or something

wouldn't be so horrible

kinda flimsy , not a big fan of strings unless I make const but then you're making a big ass const class

[cobalt granite]

 private void spellSelect() 
    {
        if (Input.GetButtonDown("Fire1") && firing == false && selectedWeapon.Equals("Staff")) 
        {
            Debug.Log("firing-true");
            firing = true;
            anim.SetBool("Firing", true);
            //Everyspell will have their own if statement
            if (selectedSpell.Equals("Fireball")) 
            {
                Debug.Log("FireBall");
                anim.SetTrigger("Fireball");
            }
        }
    }

Like in this the last if statement, each one will have it's own spell its checking and the selectedSpell will be chosen from like clicking a button on a GUI

and then I have a big state animator tree and each transition to each spell has a unique trigger

[rich adder]

imagine how big you have to make the if statement to check all possibilities?

even with a switch

[cobalt granite]

Yeah thats true, it would be like 30 different if statements

[sour fulcrum]

Whats the cleanest way to cast a Vector3 to Vector3Int? dealing with it often enough to where I’d rather not constantly do (int)x, (int)y,(int)z

[cobalt granite]

well I plan on having them in like classes, like fire ice electric, so I guess it could check what class its in then what spell exactly to shorten the amount of checks

[rich adder]

i usuaully store my specifc logic in the specific ability

my caster doesnt care what its casting, the cast takescare of it

it justcares about cooling times and speed

[sour fulcrum]

Na ScriptableObject’s are what you want here. They are the equivalent of prefabs but just for holding data.

[ivory bobcat]

https://docs.unity3d.com/ScriptReference/Vector3Int.FloorToInt.html

[sour fulcrum]

Tyty, dunno how i didnt find that

[cobalt granite]

so your saying have it be like a method called, castSpell(currentSpell) and then that currentSpell class would have all the script to it

[cobalt granite]

I'll definetly look into those too

[rich adder]

it depends on the game

your spell would probably have a child class to its specific type of spell

[sour fulcrum]

If you did it via ScriptableObjects you could just store a

string animationString

Then do animator.SetTrigger(currentSpell.animationString)

[rich adder]

whatever is mechanically the same would have the same SO/Class for behavior

only data type changes

[cobalt granite]

Okay, well thank you for all the info, hopefully it all turns out okay

[rich adder]

eg all weapons/rifles have the same thing going on mechanically. Fire projectile, only thing that changes is the rate of shooting etc.

[cobalt granite]

Ohh so have all the common data to each spell on the castSpell method and everything else in its seperate thing?

[rich adder]

the commonality would be the method that fires this and behaves according to the data

instead of CastingFire, you just Cast(fire)

then cast method knows what values to use from fire and how to handle the rest

[cobalt granite]

Okay, yeah that makes sense

thank you

[rich adder]

def give scriptable objects a look, they're pretty powerful for this stuff

[tame mist]

hello, I have cars that will become children of lifts in a mechanics garage. When the lift goes up by animation, the car is supposed to move up with it. but it doesn't seem to work when the cars rigidbody is attached to it.

I tried different combinations of setting the rigidbody of the car to isKinematic = true, detectCollisions = false, and useGravity = false
but with those options it seems like the car will raise up just a little bit, but not all the way up with the lift.
the only thing that has worked so far is completely removing the rigidbody on the car at runtime before it goes on the lift and then when it comes back down off the lift I put a rigidbody back on the car and give reference to the few places in scripts that need it.

the problem i'm having with that approach is that it seems to mess up the way the vehicle drives. like for example when turning it tilts way too much, yet all the same settings seem to be applied to what controls the car mechanics.
I really don't want to completely remove the rigidbody from the car as it seems to give me problems, but I don't know why the other approaches I took didn't work.
any ideas?

[acoustic arch]

https://hatebin.com/uaqcdyhvlb - Inventory Manager, grabs icon from the item data to be put in inventory slots
https://hatebin.com/eamjjznyko - Item Data Scriptable object
https://hatebin.com/ctccksuysr - Used to define the item data for each items prefab
https://hatebin.com/frwqjjvqri - Menu Manager, when opens inventory lists items inside of it

currently the items can go in the inventories list in the script

but it cant ever show up in the games inventory

[acoustic arch]

i get an error from the 1st script from line 48, object not set to instance of object

if i add an item, itll create another slot at the bottom

[teal viper]

Setting the rb to kinematic should work. If it doesn't, it must be some of your code interfering.

Make sure you don't run any of the car driving logic, when it's in the lift.

If it's using wheel colliders, might want to disable them too(I don't remember if they can be disabled though)

[teal viper]

var itemIcon = obj.transform.Find("icon").GetComponent<Image>()

There are 3 things that can be null here:
-obj
-the "icon" object
-the image component.

Check which is it to know how to deal with it.

In fact, the past thing is irrelevant, so only 2.

[acoustic arch]

so i changed obj to be set to itemContainer

now i get the error from line 47

which i think is an improvement

GameObject obj = itemContainer;
var itemIcon = obj.transform.Find("icon").GetComponent<Image>();

[teal viper]

What error, and what's on line 47 now?

[acoustic arch]

null

instance not found

[swift crag]

we have no idea what line 47 is

you posted several files and you've made changes since posting them

[acoustic arch]

https://hatebin.com/evyejkqkah

[swift crag]

you are not getting an error from line 47

that's impossible

GameObject obj = itemContainer;

itemContainer is a field, and reading a field cannot cause a NRE

[teal viper]

Probably the old code

[acoustic arch]

NullReferenceException: Object reference not set to an instance of an object
InventoryManager.ListItems () (at Assets/Scripts/Item Scripts/InventoryManager.cs:47)
MenuOpener.Update () (at Assets/Scripts/UI/MenuOpener.cs:21)

https://hatebin.com/qzgffalrhj - menu opener

[swift crag]

ensure that you've saved the file

[tame mist]

yeah idk, I pretty much disabled any scripts running on it beforehand so i don't think that's the issue, but maybe I should go through and look again.
also, the wheel colliders didn't seem to effect the car not lifting. I leave them on when I remove the rigidbody of the car it seems to work fine lifting.

[swift crag]

this would be consistent with deleting line 47 and then saving before adding GameObject obj = itemContainer; back in

[acoustic arch]

100% sure

[swift crag]

The line of code literally can't cause an exception. It's an instance method accessing a field on its own object.

[acoustic arch]

yeah weird

[acoustic arch]

still

oh

mb

[swift crag]

I presume itemContainer is a prefab. Grabbing the Image from the prefab would not make much sense.

[acoustic arch]

im slow

var itemIcon = obj.transform.Find("icon").GetComponent<Image>();

is the issue

the line is different on mine than hatebin and i said hatebins not mine

[teal viper]

Making an rb kinematic is the same as just removing it, unless there's something else that's moving it(like your code or wheel colliders).

[teal viper]

Well, then it's still the same issue that I mentioned originally.

And still the same way of dealing with it.

[acoustic arch]

.

[swift crag]

I would strongly suggest making a component for the "item container"

so that you can instead have

ItemContainer itemContainerPrefab;

[teal viper]

Also, yeah, what Fen mentioned about it being a prefab

[swift crag]

that component can have a field that references the container's Image.

public class ItemContainer : MonoBehaviour {
  public Image icon;
}

e.g.

I almost never store things as a GameObject

[acoustic arch]

like what i did here

public class Item : MonoBehaviour
{
public ItemData ItemData;
}

[swift crag]

the important idea is that it'll let you access its components without having to go digging around for them

using Find and GetComponent is very brittle

[acoustic arch]

yeah

[swift crag]

if you rearrange the prefab a little, it can suddenly stop working

[acoustic arch]

so make a new script like this

[swift crag]

I've been doing some messy UI work today, but I never had problems with components randomly not being found

[swift crag]

yes

[acoustic arch]

alrightr

[acoustic arch]

i still dont super understand what im doing with this

[swift crag]

the point is that you'll be able to do this

var holder = Instantiate(itemContainerPrefab);
holder.icon.sprite = whatever;

instead of

var holder = Instantiate(itemContainerPrefab);
holder.transform.Find("icon").GetComponent<Image>().sprite = whatever;

[acoustic arch]

do i put this script on my items prefabs?

[acoustic arch]

but it does look better

[swift crag]

You would attach it to whatever your item container prefab is, yes.

[acoustic arch]

ohhh so my slots

[swift crag]

You would then reference the prefab like this.

not as a GameObject

[acoustic arch]

yeah

[acoustic arch]

it cant be like a GameObject

[swift crag]

i don't understand what you mean

[acoustic arch]

just ignore that

i was just restating what you said

i got another error tho

ArgumentException: The Object you want to instantiate is null. UnityEngine.Object.Instantiate[T] (T original) (at <c2d036c16ca64e0eb93703a3b13e733a>:0) InventoryManager.ListItems () (at Assets/Scripts/Item Scripts/InventoryManager.cs:48) MenuOpener.Update () (at Assets/Scripts/UI/MenuOpener.cs:21)

[swift crag]

well, assign it

you didn't assign anything to the field

[swift crag]

I use GetComponent about a dozen times in total in the game I'm working on right now.

Eight are GetComponentsInChildren calls used so that I don't have to manually drag objects into a list (which are always parented below the caller).

The other few are all TryGetComponent calls in physics messages, like OnTriggerEnter

[upper spire]

bump 🙂

[acoustic arch]

to the image?

[swift crag]

No. You tried to pass a null reference to Instantiate.

I presume you passed itemContainer to it

That means itemContainer is null.

Assign the prefab to it.

[acoustic arch]

public class ItemContainer : MonoBehaviour {
public Image icon;
}

this image

[swift crag]

I said nothing about an Image.

[swift crag]

Show me your code again if this is not the case.

[swift crag]

It doesn't matter whether icon is assigned or not on your prefab if you don't have a reference to the prefab at all

[tame mist]

alright I'll look into it a little more

[teal viper]

I don't think there's a straight forward way, as the checksphere doesn't even return the hit info.

[acoustic arch]

i dont understand what im assigning this too

im being very dumb

[swift crag]

to reiterate:

• your "item container" prefab should now have an ItemContainer component on it
• your InventoryManager component should have a reference to this prefab. The reference should be in a field of type ItemContainer

[upper spire]

hmmm, i it possible i can use a checksphere to get if its hidding something then a ray to grab the info?

[swift crag]

This field should replace the GameObject field you originally had.

the itemContainer field should now be an ItemContainer.

[acoustic arch]

oh the script as the component

[swift crag]

I don't know what that means

[acoustic arch]

the component ItemContainer is the script

[swift crag]

I only use "script" to refer to the actual source code.

The thing you see in the inspector is a component.

[teal viper]

You don't know what it's overlapping with though. The only thing it tells you is that "something" is overlapping. Might want to use OverlapSphere instead. At least that way you know what object is overlapping.

[acoustic arch]

alright

[swift crag]

You can reference a prefab by any component on the prefab's root object

[upper spire]

alright

[swift crag]

When you instantiate it, you'll get a whole new object

(it doesn't just duplicate the component or something)

public ItemContainer itemContainerPrefab;

void Start() {
  ItemContainer myContainer = Instantiate(itemContainerPrefab);
  myContainer.icon.sprite = ...
}

[acoustic arch]

i had

var holder = Instantiate(itemPrefab);

[swift crag]

That will work, as long as itemPrefab's type is ItemContainer.

Is that the case?

[acoustic arch]

yes

ItemContainer myContainer = Instantiate(itemPrefab);

        myContainer.icon.sprite = item.icon;

[swift crag]

okay, good. and did you drag the prefab into the itemPrefab field in the inspector of the inventory manager?

[acoustic arch]

oh it wasnt public

i was confused for a second

or seralized

neither

[swift crag]

that will prevent it from showing up, yeah

[acoustic arch]

sorry you have to deal with me im trying to progress learning 💀

well

now the error is in line 50

NullReferenceException: Object reference not set to an instance of an object
InventoryManager.ListItems () (at Assets/Scripts/Item Scripts/InventoryManager.cs:50)
MenuOpener.Update () (at Assets/Scripts/UI/MenuOpener.cs:21)

[swift crag]

okay, so what's on line 50?

[acoustic arch]

myContainer.icon.sprite = item.icon;

is it from the myContainer or item.icon?

like what isnt being set

[swift crag]

use the thread, please

[acoustic arch]

thread?

[swift crag]

i started a thread here.

[acoustic arch]

mb

[mossy arrow]

How do i fix this, So when I hit the pipe it should be a scene and i can play more but it is not poping up, So hlow do i fix this?

[swift crag]

use Debug.Log statements to check if your code is running at all

[mossy arrow]

where do i use it?

in what code?

[summer stump]

In OnCollisionEnter for one

Also in GameOver

Does the LogicManager have the Logic tag?

[frozen mantle]

i know there's a way to simplify this but this is just to catch all edge cases for my enemy AI, lol
if((playerInSightRange && !playerInAttackRange && playerInLineOfSight) || aggroTime <= chaseTime && (!playerInAttackRange || playerInSightRange && playerInAttackRange && !playerInLineOfSight))

[frozen mantle]

wait actually thinking on this, this doesn't work because now my line of sight mechanic is moot

ugh

[upper spire]

how can i get the movement speed of a non rigidbody object?

[swift crag]

you would have to measure it over time

game objects don't have a velocity

[sour fulcrum]

My brain can't think of any ways to clean that up specifically but could maybe be worth having a property or two that contains that big check instead for better readability?

[frozen mantle]

true

[elfin eagle]

I have a question so I have a game object in scene one, and in scene two there is a prefab of that game object. My character has a script attached to it that the game object in scene 2 needs to access but it cant since it is from originally from scene 1 (Im using do not destroy on load). I need help to find a way that the gameobject in scene 2 can access it when the player enters the scene

[sour fulcrum]

I might understand it wrong since I don't have the full context but maybe worth seperating your bools into

hasValidTarget => playerInSightRange && playerInAttackRange && playerInLineOfSight
readyToAttack => aggroTime && chaseTime
hasValidAttack => readyToAttack && hasValidTarget

[mossy arrow]

I’m not sure

[summer stump]

Look at the inspector for it then. Tags are at the top
You are searching for it by that tag

[sour fulcrum]

also just a random guys opinion but playerInSightRange might be better named playerInRangeOfSight so it's consistent with playerInLineOfSight

[mossy arrow]

Wait I’m taking a really big shit rn

[mossy arrow]

The game over needs a tag?

[summer stump]

GameOver is a method.
The object with LogicScript attached needs the tag

Looks like you called that object Logic Manager

Tags go on objects

[mossy arrow]

last one?

[summer stump]

That's it, and you got it

[mossy arrow]

so uhm

does it work?

[summer stump]

Does what work? FindGameObjectWithTag("Logic") works

[mossy arrow]

nope it does not work

[summer stump]

Did you do the debugs to check the rest?

[mossy arrow]

so what do i do rn

how do i do that?

[mossy arrow]

act like ur talking to a 13 years old ok?

it makes things not hard for me

[summer stump]

I was doing stuff like this at 13, so 🤷‍♂️ (not unity, but light coding)
https://docs.unity3d.com/ScriptReference/Debug.Log.html

Read the docs, it has examples

[mossy arrow]

I am 13

[ashen ferry]

how could I place points on a sphere but each must be atleast x distance away from any other

[summer stump]

Ok 👍

[mossy arrow]

I dont get what u mean by use debug

[summer stump]

Did you look at the link?

It literally has example code

[mossy arrow]

yes but it says use debuh

[summer stump]

I mean... not really?

Just add code like the example to the places I said above. Anything. Then the stuff you write in Debug.Log() will show in your console

Debug.Log("words");

[mossy arrow]

so i write Debug.Log() or Debug.Log("words");

btw it has to look like this

[summer stump]

Bro, look at the link. Take a minute to think about it. Take a minute to think about how you can use it. If you need to, look up a tutorial on it.
You are trying to determine which functions are running, and using Debug logs will help with that, because you will only see the words in the console when the code runs

13 is MORE than old enough to figure this out

[mossy arrow]

well im dumb............. lol

[mossy arrow]

also i dont get what u want me to do ur saying to read all that but i dont know why im reading all of that

[summer stump]

Age old excuse a lot of people tell themselves

[summer stump]

You add the code to a function. If the function runs, you see the words in your console... so simple

[mossy arrow]

ok there

so know i will ask 1 more time at the end of what script do i put Debug.Log() or Debug.Log("words");?

[summer stump]

Neither... dang bro

[mossy arrow]

THEN WHAT!...

[summer stump]

You add text in the method call. Text that makes sense and is descriptive

[mossy arrow]

bro im so lost

"You add text in the method call."????????

[summer stump]

You may want to stop doing unity and do a beginner c# course then...

Do you know what a method is?
The things with these: ()

You call a method when you write that somewhere.

Except when you are declaring the method (when you see something like public void in front)

Debug.Log("any kind of thing I want to write here") calls a method that writes that text into your console

If you write Debug.Log("my oncollisionenter method successfully ran") inside your Oncollisionenter method, wouldn't that help determine things?

[mossy arrow]

so it talks to me when i use Debug.Log

ok so do i use Debug.Log

like this

[rich adder]

its underlined red

you're missing something

[mossy arrow]

OH

[rich adder]

Log is a function

[mossy arrow]

WAIT

this???

[rich adder]

it takes parameters

[wintry quarry]

Mouse over it

[rich adder]

read the errors
