yeah, foreach will mess you up if you do edit the ienumerable

@rich adder no I didn't mean that at all. I meant something close that I could look at and adapt to what I want, but everything I've seen is about creating a 'linear' level etc.

I Fixed the Dungeons In Minecraft!

Hate the classic box dungeons? I re-imagined the classic Minecraft Dungeons using jigsaw blocks to add custom structures to Minecraft with no mods using datapacks! And this video is a complete guide from the basic concepts to the technical details of how to make custom structures to Minecraft for yourself!

i figured it out thanks now my game has somewhat functional multiplayer

wintry quarry
#

or the alternative I mentioned

queen adder
#

so im trying to spawn prefabs in but its not showing but it is spawning?

topaz mortar
rich adder
wintry quarry
gaunt ice
#

take a look on the camera position, scale of prefabs

queen adder
#

maybe let me check

#

im new to unity

#

so mabey lol

rich adder
#

it must be smaller than the scene objects

queen adder
#

-10

rich adder
#

ok and how about spawned objects

queen adder
#

1370.9

ruby python
#

view dsitance?

rich adder
#

XY wise

polar acorn
queen adder
#

when i drag the prefab in i can see them but when they spawn in they dont show up

ruby python
#

look at your cameras view distance. it defaults to 1000

rich adder
polar acorn
rich adder
#

cause Z is already too far

#

but should stil appear

#

since Orthographic has no depth

ruby python
#

ah my bad, missed that

gaunt ice
#

maybe the camera is perspective, it is extremely small

rich adder
#

yeah maybe

polar acorn
rich adder
#

shite could be clipped

topaz mortar
#

works perfectly

rich adder
#

yeah wheels are weird man yu have to set them up in a certain axis

queen adder
#

ok so now its not even showing up in the scene view

rich adder
ruby python
#

What's your cameras far clipping plane?

queen adder
#

is there a vc i can join to show?

polar acorn
ruby python
queen adder
ruby python
#

Show the camera settings

polar acorn

whats that mean

yeah goodluck with that

queen adder

#

VS installer is shite

queen adder
rich adder
#

had to reboot my whole system one time cause it kept telling me couldn't install VSredC++
and another VS installer was in use
total shite show from Microsoft @modest barn

ruby python
polar acorn
ruby python
#

Change that 1000 to 2000 or something

polar acorn
queen adder
#

i did now my player wont show uo lol

polar acorn
#

it should not be that far from the camera

rich adder
queen adder
#

ok

rich adder
#

that aint the pipe you spawned. try again

polar acorn
queen adder
#

thats where the pipes spawn

polar acorn
rich adder
#

also You are configure things with Center pivot mode. guaranteed your Pivot is wayyyy further than you thought

queen adder
rich adder
#

hate that Unity defaults it to that..

polar acorn
modest barn
polar acorn
#

Why is it that far away

grim eagle
queen adder
#

so how do i change that

#

what do i put it to

rich adder
polar acorn
sonic remnant
#

Thankyou ā¤ļø

polar acorn
#

You define the position you spawn it at

ruby python
#

Your spawner is at z5, so that should be at z5 too imo

rich adder
#

I still think the pivot is probably not where thy think it is

#

Unity is putting it on Center which looks ok

#

but when yu spawn it it uses the Pivot point

queen adder
#

how do i change the pivot

rich adder
#

which is probably not where Center is showing

rich adder
polar acorn
rich adder
#

so we can see

queen adder
#

ok i clicked pivot

rich adder
#

drag pipe prefab in and press F

queen adder
#

ok i did'

rich adder
#

ss

queen adder
rich adder
#

oh well its that one is good then

polar acorn
#

that's fine

queen adder
#

it still not showing up and idk why lol

rich adder
#

so lets see the code that spawns it @queen adder

queen adder
#

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

public class PipeSpawnScript : MonoBehaviour
{
public GameObject pipe;

// Start is called before the first frame update
void Start()
{
    
}

// Update is called once per frame
void Update()
{
    Instantiate(pipe, transform.position, transform.rotation);
}

}

rich adder
#

also when you spawn it with code you could also Press F on it and see where it went

polar acorn
eternal falconBOT
rich adder
#

omg why is it in update

#

lol

queen adder
#

i followed a tut

rich adder
#

shouldnt this be like crashing at some point

wintry quarry
queen adder
#

first game lol

wintry quarry
#

also yes you're spawning a new pipe every single frame

#

which is defintiely not what the tutorial did lol

queen adder
#

yea i havent fixed it yet

polar acorn
#

This is spawning a pipe every frame so the reason you don't see anything it's probably because you're getting like, minutes per frame

queen adder
#

i wasent done yet i just needed to see rthem spawning

polar acorn
queen adder
#

ok

amber spruce
#

so im trying to make a double jump for my character how would i check for when they land to reset the jump counter

wintry quarry
queen adder

public class PipeSpawnScript : MonoBehaviour

    public GameObject pipe;
    public float spawnRate = 2;
    private float timer = 0;

    // Start is called before the first frame update
    void Start()
    {
        
    }

    // Update is called once per frame
    void Update()
    {
        if (timer < spawnRate)
        {
            timer =+ Time.deltaTime;
        }
        else

            timer = 0;
        }

        Instantiate(pipe, transform.position, transform.rotation);
    }
}
#

fixed

polar acorn

Could you answer the question?

queen adder
#

ohhh

#

one sec

amber spruce
queen adder
#

the z is 5

polar acorn
rich adder
#

its not that difficult

queen adder
#

its not even spawningthem at all

wintry quarry
rich adder
#

wdym isn't right? do you see you have to configure the vehicle with axis of wheels on Z

#

thats how wheels work

queen adder
#

yea its not doing anything

ok so they are spawning and i can hit them but i still cant see them @rich adder

amber spruce

WHY is the clipping plane like that

queen adder
#

someone said to change it to that

rich adder
#

no you put it back how it was

wintry quarry
#

no way did anyone say that

queen adder
#

what do i change it to

wintry quarry
#

the default, like 0.3 or whatever

craggy lava
queen adder
#

whats the defalt

rich adder
#

yes 0.3 - 1000

wintry quarry
polar acorn

so you did that and didnt tell us

#

wonderful

polar acorn

ok my bad

ok i fixed it

#

now what

how can i make my gameobject the be on top of the ui when hovering with the mouse over,

queen adder

rich adder
queen adder
#

same thign they are in scene view and i can hit them but cant see

polar acorn
queen adder
#

holy shit really far

#

ok lol

#

fixed it

#

thank you guys so much

quiet pasture
rich adder
#

put the gameobjects one higher

#

if they're not sprites then it gets more tricky

#

youd have to change the Plane distance and make sure it correct

quiet pasture
#

They are empty game objects that have sprites and text(a card)i've tryed sorting layer and it didnt work for me,also,the gameobjects are somehow seetru in scene but not in game

(Quick?) question: I'm using Resources.Load<X>("Something") to load a Prefab. At some later stage i want to check wheter a given GameObject is instantiated from the same Prefab (or is of the same type or whatever way is the best). Any ideas?

you're assigning this object's rotation to the bullet when you instantiate it

i thought it would adding to the object rotation

slender nymph
#

no, it assigns exactly the rotation you pass

hey so how would i go about making a grounded check

#

huh?

rich adder
#

Especially in a code channel, we'd have to see the code @tiny vault

#

we're not mind readers we don't know your exact setup

tiny vault
#

i have an idea i will give you the code if it doesnt work

amber spruce
# slender nymph huh?

i thought about it and reaslised for double jumps it would be better for just if they collide with anything because if you land on a enemy or smth then you still cant jump

tiny vault
#

okay it doesnt

slender nymph

would it matter if i just send a part of the code right here

# rich adder store it in a variable? not sure what youre asking exactly

Yeah, thanks. Not sure how to formulate. I'm filling a Dictionary<GameObject, int> using Resources.Load to get the GameObjects and incrementing the int for every Resource. Later I'll get a (random) GameObject and want to get the associated int from the Dictionary.

Lets say I have Prefab "Red" and Prefab "Green" => Dictonary([Red, 1], [Green, 2].

Now i get GameObject go which might have been instantiated from the Prefabs "Red" or "Green". I can't throw go at the Dictionary, because that specific GameObject won't be in the Dictionary.

i donā€™t understand how collision gets factored into this

tiny vault

i made a simple camera lerp script

[SerializeField] GameObject player;
    [SerializeField] Vector3 cameraOffset;
    [SerializeField] float cameraSpeed;

    void Start()
    {
        
    }

    // Update is called once per frame
    void LateUpdate()
    {
        Vector3 NewPosition = new Vector3(player.transform.position.x + cameraOffset.x,
            cameraOffset.y,
            player.transform.position.z + cameraOffset.z);

        transform.position = Vector3.Lerp(transform.position, NewPosition, Time.deltaTime * cameraSpeed);
    }

this smoothly follows the player in editor but when i make a build it sometimes feel jitery any idea why its happening

that should smooth everything out

The basic idea I have is that I have a 'starter/spawn' room (blue in the image) which has four doors, one on each 'face' which I'd like to iterate through and spawn new rooms onto each 'door' (this happens every time there's a new door that has a free spot next to it. I had a method that sort of worked, but it's wrong, so looking for another solution but I'm at a bit of a loss on how else to do it. All I need is the steps, I can work out the code myself. šŸ˜•

#

you mean you want a dictionary where you input a string, and it spits out the prefab gameobj associated with it?

#

i just donā€™t understand your goal here

quiet dune
#

Simplyfied rephrase:

GameObject prefab1 = Resources.Load<GameObject>("Test1");
GameObject prefab2 = Resources.Load<GameObject>"Test2");
GameObject instance = Instantiate(prefab1);

What comparison can i do to get a "true" out of prefab1 and instance, but a "false" out of prefab2 and instance?

buoyant knot
#

you mean you want to know you have a running instance of prefab1?

amber spruce
slender nymph
#

if you're going to ask for advice in here, why not actually take the advice instead of ignoring it and implementing your own (worse) thing?

buoyant knot
#

Give all the gameobjects a component to communicate with an entity-ledger system. This component can hold different types of info, and in this case holds a ref to the relevant prefab.
When this component has its Start(), it tells an EntityLedger singleton to log a new instance (itself) under prefab1. When it is destroyed, it tells entity ledger to delist itself.

amber spruce
rich adder
#

they advised something like raycast, this isn't even close to raycast lol

slender nymph
buoyant knot
#

then you can query entity ledger, to see how many of each instance you have, or even to control everything associated with a given prefab

amber spruce
slender nymph
#

you're also not even checking the tags correctly so whatever tutorial you followed is garbage

rich adder
buoyant knot
#

entity ledger can maintain a Dictionary<GameObject, HashSet<EntityDataHolder>>,
where the key is the prefab, and EntityDataHolder is whatever component weā€™re putting on the gameobject to keep tabs on it.

polar acorn
# ruby python The basic idea I have is that I have a 'starter/spawn' room (blue in the image) ...

Put a script on the room that has a list of doors on it. Give the doors a script that lets you know if a door has something on the other side of it. When you spawn a room, call a function on it that checks each door, if it's empty, spawn a room there (which will itself call this "door checking" function when it is spawned). If a room spawns and all of its doors are occupied, you can just return from the function without spawning anything else, which serves as your escape condition from the recursion

buoyant knot
#

i do this sort of pattern a lot, and itā€™s very helpful to just keep tabs on things

quiet dune
buoyant knot
#

prefabs are all of type gameobject

#

meaning you need to give the gameobejct a way to identify itself

ruby python
#

Thanks guys, looking at Wave Function Collaps atm. but will have a look at what you suggested @polar acorn šŸ™‚

buoyant knot
#

Tags can work, but that can break any other uses for tags that you have

#

like, I do a similar system for reference frames, entity ledger, and physics movers. All of these have singletons that need to keep track of ALL active instances

#

so I usually have the one Singleton class that holds a collection of all the individual instances. And the individual instances have a monobehaviour to communicate to it. To tell the singleton ā€œinclude me now.ā€ and ā€œiā€™m gone nowā€

#

otherwise, you need to do fancier things to make sure you keep perfect track of things that enter/leave your records

#

which is a giant pain in the ass

#

itā€™s better to have a monobehaviour just automatically take care of registering/deregistering itself from a common place.

#

if you donā€™t care if it has been destroyed, and just want to count ā€œtotal active ever made, including destroyedā€, then you donā€™t need the extra monobehaviour

#

itā€™s like a hotel, and making sure each guest signs in and checks out, so that the hotelā€™s ledger can tell you exactly who is in the hotel at any time

#

if you donā€™t ask for checkout, youā€™re more like a movie theater, who just wants to count total tickets sold ever

#

understand?

quiet dune
#

@buoyant knot Thanks for all the ideas! I think using the tags should work. They are already tagged differently anyway.

buoyant knot
#

sounds good. remember you only get ONE field for tags

#

so use it wisely

timber tide
#

Wave Function Collapse sounds like it would make a great band name

dense root
#

So I'm trying to make a Galaga style projectile spawner, how do I go about spawing the SpriteRenderer and any other components necessary?

// Projectile spawner
if (Input.GetButtonDown("Fire1"))
{
    // Instantiate projectile at the position and rotation
    Rigidbody clone;
    clone = Instantiate(projectile, transform.position, transform.rotation);

    // Give the cloned object an initial velocity along the current object's z-axis
    clone.velocity = transform.TransformDirection(Vector3.forward * 10);
}
polar acorn
quiet dune
#

@buoyant knot Jep, tags did the trick šŸ™‚ I've been using tags to identify the instances already anyway, so this is acutally a straigt forward solution to that problem. If I'm running into problems with the tags in gerenal at a later time, I'll have to find another solution to identifying them. Thanks again!

buoyant knot
#

sure. make sure to use a plugin to avoid using tags as plain strings

wintry quarry
#

you don't need to separately spawn different components

dense root
#

I see

buoyant knot
#

there are several. I have one that just autogenerates a static class with public constants. So I can use Tags.PLAYER, instead of ā€œPlayerā€ and misspelling it

dense root
#

Let me do some tinkering and I'll get back to you with any issues that might arise

quiet dune
buoyant knot
#

openupm has several different plugins

quiet dune
buoyant knot
#

you have to click on a menu, then it autogenerates the class

quiet dune
#

That sounds convenient enough

buoyant knot
#

the biggest time cost is setting up openupm, which youā€™ll probably want for other things anyway

How do I go about making my prefab originate from the player position?

timber tide
#

There's like 6 different overloads for instantiate go look em up

buoyant knot
#

is there an easy way to make coroutines that just execute at a specific time within a given frame?
I find myself wanting to do things like: yield return new WaitForEndOfThisFrame() or WaitForEarlyFixedUpdate()

polar acorn
buoyant knot
#

so, for things like pausing, I want to be able to receive a pause command at any point of a frame, then basically wait for everything going on in the frame to resolve, then execute the pause

polar acorn
summer stump
buoyant knot
#

doesnā€™t that wait until next frame?

polar acorn
#

Yes

#

That's what you'd want, right?

buoyant knot
#

meaning i could have a fixedupdate frame in the middle sometimes

polar acorn
#

The current frame ends

#

then you do the pause

rich adder
rich adder
summer stump
buoyant knot
#

early fixed update is a bigger deal imo, because WaitForFixedUpdate executes after collision callbacks

rich adder
buoyant knot
#

so if I try to move something in coroutine that does WaitForFixedUpdate, then there are potentially many normal Update frames where things can change before we get to the FixedUpdate that actually plans to evaluate that call

#

but I wanted to issue the move command on the same fixed update frame where I know it plans to go off (before physics sim)

#

does this all make sense for why I want that level of control?

dense root
amber spruce
buoyant knot
#

i think my pausing affects how that coroutine interacts with my physics system because pausing happens in Update loop, and stops everything.

mostly use Cast in 2D

rich adder
#

reference it

#

pass it as a variable , it's a property inside the Transform player.transform.position

buoyant knot
#

for simple shapes, I ran some benchmarks, and it is almost as fast as a raycast, but it has obviously a lot more accuracy to the shape

#

like, Physics2D.Raycast and BoxCollider2D.Cast are similar speed

rich adder
#

mindblowing that They have an overlap for 3D in phyx for Mesh Collider but not in unity

buoyant knot
#

spamming a fan of raycasts is a lot more expensive and innaccurate than .Cast for a shape

rich adder
#

PxScene::overlap() query searches a region enclosed by a specified shape for any overlapping objects in the scene. The region is specified as a transformed box, sphere, capsule or convex geometry.

Physics.OverlapConvex

buoyant knot
#

ouch

rich adder
#

would be neat

buoyant knot
#

they are losing a ton of market share now to Godot, so weā€™ll see how that changes the stream of new toys

rich adder
#

its weird cause doesn't OnTriggerEnter use that?

#

You can technically make a convex shape and mark it as isTrigger

#

and use OnTriggerEnter and it works

buoyant knot
#

unity does a lot of black box things, where they get to use a tool, but we donā€™t

#

one really annoying part is how classes get sealed. so you canā€™t easily make wrappers to add fields etc

rich adder
#

closed source nonesense this would've been added ages ago, its literally in the script somewhere surely we can turn it into a Physics. class method

buoyant knot
#

thatā€™s why I think Godot will flourish, once it gets its shit together

#

it is obnoxious to code and not be able to change basic things

rich adder
#

they have lot of YEARS of R&D to catchup to

#

they are friendly with other things that are nice (newer .net) but still their game engine tech is very primitive

amber spruce
buoyant knot
#

you know CustomCollider2D? no reason that should be a sealed class. It is literally perfectly designed to allow you to make your own parametrized collider classes

#

instead, I need to do awkward dictionary bullshit to couple a wrapper class to it

#

which leads to a lot of issues in Awake and Start

queen adder
#

is it possible to make a thing move towards shadows
like if its in light it will go towards dark areas

rich adder
#

ofc anything is possible

#

you'd have to determine some way , what shadow area would be

#

light probes maybe

rich adder

#

so basically the instant you make the first jump the counter gets reset

rich adder
#

how do you call OnLanding

amber spruce
amber spruce
# 
public void OnLanding()
{
    if (IsGrounded())
    {
        animator.SetTrigger("Land");
        jumpcounter = 0;
    }
}

but it has the if to make sure it only happens when your touching the ground

rich adder
#

above if()

#

jump and try again

wraith wadi
#

is there a way to delay part of the function by 10 seconds or 20 seconds without using coroutine and invoke.
the part i want to delay is within multiple if statements so if i use script method it doesn't work.
time += Time.deltaTime. it doesn't work either

rich adder
amber spruce
rich adder
#

it doesnt change any functionality

amber spruce
#

idk

rich adder
#

you have to observe the log when you jump

wraith wadi
rich adder
rich adder
#

idk what that means in this context

#

very least share the code you currently have

wraith wadi
# rich adder whats "not working"

when i use
timer += Time.deltaTime
then it should increase the timer value by 1 every second but instead it increases its value by 0.01 something

amber spruce
rich adder
#

in jump code

amber spruce
#

so the problem seems to be it adds to your jump counter before you even have a chance to move

#

because it ends with true

rich adder

rich adder
amber spruce
#

no but i increase jumpcounter the instant i hit space

How do I convert the transform to a Vector3?

rich adder
amber spruce
polar acorn
rich adder
#

transform contains more than just a vector3

amber spruce
# 
 public void OnLanding()
 {
     Debug.Log(IsGrounded());
     if (IsGrounded())
     {
         animator.SetTrigger("Land");
         jumpcounter = 0;
     }
 }

this is called via the Update()

charred spoke
dense root
rich adder
charred spoke
#

But keep in mind that is not converting it simply using the position property of the transform

dense root
#

Hmm this bit of code still puts the projectile dead center in the screen

// Projectile spawner
if (Input.GetButtonDown("Fire1"))
{
    // Instantiate projectile at the position and rotation
    Instantiate(m_projectile, m_paddle.transform.position, Quaternion.identity);
}
rich adder
#

which makes sense since you're only doing animation

# 
if (jumpcounter == 0 && IsGrounded())
        {
            animator.SetTrigger("Jump");
        }
        if (jumpcounter == 1)
        {
            animator.SetTrigger("DoubleJump");
        }```
#

nothing here is actually moving the transorm maybe the animation? even so then its too slow for update

Oookay, more adventures in Map Generation.

Playing around with Wave Function Collapse, and I understand a good chunk of it (followed a simple tutorial). Now the issue is that I need to 'convert it' from using X,Y in 2D space to using X,Z in 3d Space, and I'm struggling to understand what I need to change etc.

This is the entire thing (3 seperate scripts, Tile, Cell and WaveFunction.

The only place that I can see with my novice eyes that would change from 2d to 3d space is the Instantiate command, so I changed that but then I get an error. Would anyone more knowledgable be able to poke the right places please? šŸ™‚

Well here is my script first of all https://paste.ofcode.org/VSjU6M5YZDTp9s3i8b9vLz
I have a player and this player can pick up blocks and place them on the ground again. This mechanic works perfectly, but i also have some block plates where when a block is touching it and its being held by a player it will be dropped on the position of the block plate. I can also pick up the block from the block plate. The problem is me being able to place more than 1 block one 1 plate, and when i have more than 1 plates in the scene it also gets weird. Can someone help me? i use prefabs for the blocks and for the plates fyi.

i think i say in the video

#

first I would clean your script a bit, also those white blocks should be their own script

#

name.Equals("BlockPlace") using name is a big no

modest stag
#

oh

#

ok

#

it worked for the player so i thought id use it for the blockplace as well

rich adder
#

there is only 1 player so it is acceptable (still bad practice to use strings/names)

#

but for multiple cubes not ideal

#

You make a script a nd make them a component

#

so you only check component

modest stag
#

for the player or the blockplates?

rich adder
#

all of them

modest stag
#

so i dont check if the object im touching has the name Player, but i check if the gameObject has a component that is the movement script or something else?

dry tendon
#

does someone knows why do i get this both logs when i try to use google firebase I'm just doing it for android and it say something about IOS

image.png
rich adder
#

for example

modest stag
#

what does the (out Grabbable grabable do?

rich adder
#

same as doing GetComponent with null check

modest stag
#

so if the script has been found it outputs the grabable as true

rich adder
#

grabbable is just the particular component you found yes from that object

#

this way your Whitesquares can have their own slot for Grabbable lets say

#

and you can check if that slot is alreaady occupied, you can't place one again

modest stag
#

so should i now make a script for the white squares and make it so if it collides with a block it grabs it, and if its already holding one it wont.

rich adder
#

or you can manually placre it from your hand

modest stag
#

but i still want to pick them back up from the white squares

If I completely remove HandleRotation it works perfectly.

Btw, the rotation seems messed up a bit. I redid the code in my testing, and this is what I came up with:

I'm facing a challenging issue in Unity where my constructable objects are incorrectly allowed to be placed through 'Tree' tagged objects, despite having collision detection logic in place. Here's a brief overview:

I have a script attached to my constructable objects to control their placement in the game world.
The script includes an OnTriggerEnter method intended to prevent these objects from being placed through other objects, particularly those tagged as "Tree" or "pickable".
Despite the logic, the constructable objects are still being placed through the 'Tree' objects. I'm using tags to differentiate between 'Ground', 'Tree', 'pickable', and 'ghost' objects.

i have a problem with the object going through the ground and is set to valid to build aswell.

added a detection logic to my constructable script.

the ones you had for left and right I put as up and down (and vice versa)

Mouse X not MouseX

novel shoal
#

mb

#

and may as well put those directly in the Rotate call if you don't use them anywhere else

rocky canyon
#

ya, that'll work (may need modified a little to get the outcome u expect)

Will do. Thanks again

novel shoal
summer stump
novel shoal
#

but you asked me if that was the order i wanted to use

#

so i used first the x axis to rotate it vertically, then the y axis to rotate it horizontally

summer stump
novel shoal
#

i have to invert the value for the y axis, but why?

novel shoal
rocky canyon
#

iono.. why tho

novel shoal
#

but why do i have to inver those values?

rocky canyon
#

idk, for sure.. debug the values that those variables return.. and compare that to ur logic

#

im sure u'll figure out why

novel shoal
#

it's just odd that i have to inver the value for the x axis

rocky canyon
#

well in math, moving right would be Positive and moving left would be Negative (as far the x axis goes)
this also depends on where the origin is.. is it on the bottom left corner? is it in the middle? is it dependent on where the movement starts? not totally sure, but thats why i said to debug the values.. visual confirmation always helps understanding

#

could also be dependent on the thing ur moving.. does the object start upside down perhaps?

#

lots of variables

novel shoal
novel shoal
summer stump
rocky canyon
#

you should look at examples / tutorials / etc and see how they do Mouse Look movement..
usually ur rotating a child object one way and the parent another way.. so 1 object only moves in 1 dimension..
this helps prevent odd movements, and gimbal lock etc

#

in this example the camera is parented to the capsule.. the camera only moves up and down... it's the character (capsule) that moves on the X (horizontal)

novel shoal
rocky canyon
#

left and right (yes)

novel shoal
#

yeah mb

rocky canyon
#

the camera up and down moves the child (inside the capsule)

#

"Mouse Look" is the terminology if u wanna look up some tutorials or something

novel shoal
#

i am gonna make a bad example, but when i used to play fortnite i remember i could use the camera and the movement in 2 different ways

austere monolith
#

would i make multiple gun containers for multiple guns?

image.png
novel shoal
rocky canyon
#

and in ur example make sure ur moving the correct way, theres local movement and global movement.. say u rotate ur camera to the left.. and then up and down.. if ur moving it (globaly) the axis never changes.. up is always towards the sky.. so if it rotates to the left or right first (like roll on an airplane) and then you rotate it upwards.. the side of the camera facing the sky would get rotated upwards.. (not the camera's original up)

#

if that makes sense

#

it does

lol

good good šŸ€

austere monolith
#

would i make multiple gun containers for multiple guns?

image.png
rocky canyon
#

you can

#

but i'd use 1 container for all the guns

dusk hornet
rocky canyon
#

then disable and enable the child object that represents the gun

#

then u only need to move around the parent object

novel shoal
#

is there the camera movement in the junior programmer pathway in learn.unity? i am currently at unit 3 and it would help to have it there

rocky canyon
#

or u can even get more complex and instantiate and destroy the guns, but its cheaper to enable/disable than to spawn and destroy

dusk hornet
#

i have script to turn on light when im near lightswitch and press e but idk why i can switch the light whereever i want and it only works normal after my first contact with the lightswitch

okk ty

rocky canyon

rocky canyon
#

not sure.. it could

#

but even if it doesn't its better for triggers like that

#

if u have an exit might as well use a Enter.. rather than a Stay

#

stay runs every frame..

dusk hornet
rocky canyon
#

u only need the boolean flipped that 1 time

#

so enter makes more sense

dusk hornet
#

thank you

#

but im still wondering

novel shoal
#

@rocky canyon how did you learn unity?

dusk hornet
#

why i can switch the light from anywhere

#

till my first contact

rocky canyon
#

i don't have unity open so i can't test but i'll fire it up in a min

rocky canyon
rocky canyon
#

it should be off Until you enter teh trigger.. if it starts as on or w/e state is needed to enable the light, you'll be able to flip the light on until u enter and exit the trigger

#

(my guess w/o looking into it too deeply)

dusk hornet
#

thats the probleeem

#

i fixed it

#

thaank you

rocky canyon
#

no prob šŸ‘

dusk hornet
#

i ticked interactable

#

by mistake

rocky canyon
#

yup, thats a common mistake. the inspector will override the values u have in the script

dusk hornet
#

for him interactble was tru so pressing e activtes the light

rocky canyon

so im trying to export my model from Maya to Unity using FBX but the model always lacks textures despite exporting with "embed media". How do i fix this?

Hey guys, if I create an IEnumerator like that it should make it true and 1sec later false right? because it is not working

    private IEnumerator loadSuccessText(float wait){
        loadSuccess.gameObject.SetActive(true);
        yield return new WaitForSeconds(wait);
        loadSuccess.gameObject.SetActive(false);
    } ```
#

it turns into true but never false

AHHHH yes omg Timescale is 0

#

#

haha thank you

rocky canyon
# austere monolith ok i did the thing you said for the containers, how can i make it so it doesnt f...

umm, if its a child it will always follow around the parent (container)
to not make that happen you could

  • set its position manually every frame.. transform.position = (place you want it) and then you'd have to have logic to set it to the parent's position and then stop manually changing its position
    or
  • you can set its parent to null in the code (that will unattach it from the parent) - it will no longer follow it around
    then when you need to
  • you can set its parent to be the player or gun holder or w/e (set its position to the place you want it)
    then it'd follow it around as a child normally would
#

not exactly sure why you wouldn't just keep it where it is.. (if you have no guns you can just disable all the guns)
when you DO have a gun you just enable it.. and it will already be parented and where it neeeds to be

#

the weapons you pickup should not be the same as the weapons your character has..
(that'd be the only reason i can think of as to why u wouldnt want them just to be attached all the time)

#

the pickup gets destroyed.. then ur script just does some logic to let the player have the weapon (be able to enable it)

What are all the ways I could use to repeat a certain part of code a certain amount of times?

for context, I am making a spawn point for enemies, where the game repeats the same line of code multiple times via calling the same private void in the script multiple times.

my problem is that I don't know the proper way of doing it, since using a while loop often freezes Unity itself when it gets called via the player touching an object that tells the enemy spawnpoint to activate the spawning code lines (unless I get rid of the enemy-counting code which is in Update).

Yep just a for loop

why my CC .isGrounded is returning true and false rapidly? How this check works, why when CC is on ground it returns false

I am already refactoring it and that's why I noticed that my cc isGrounded returns true and false

    private void FixedUpdate()
    {
        if (!IsOwner) return;
        
        isSlopeTooStep = CheckTooStepSlope(); // This should be in GroundMove or something...

        if (WantToCrouch())
            CrouchMove();

        print(_controller.isGrounded);

        if (_controller.isGrounded)
            GroundMove();
        else
            AirMove();

            if (CheckCeilingHit())
            {
                Debug.Log("HItted Ceiling!");
                playerVelocity.y = -0.5f;
                AddGravity();
            }
        

        /* Calculate top velocity */
        Vector3 udp = playerVelocity;
        udp.y = 0.0f;
        if (udp.magnitude > playerTopVelocity)
            playerTopVelocity = udp.magnitude;



        playerVelocity += baseVelocity;
        _controller.Move(playerVelocity * Time.fixedDeltaTime);
        playerVelocity -= baseVelocity;

#

In GroundMove, you set the player's Y velocity to 0 if they're grounded. This means your next call to .Move doesn't touch the ground, and thus sets isGrounded to false. Instead of setting it to 0, set it to a small negative number so it touches the ground

i got an prefab object and i want to intantiate a gun object as child of this prefab so i get the gun to move with the prefab but got this error

#

u got to set its transform to the Instantiated prefab in the world..

#

not the actual prefab

amber spruce
polar acorn
woven crater
#

instance of the prefab rather than the prefab itself?

polar acorn
#

yes

#

Making a prefab a child of an object in the scene doesn't really make sense

rich adder
woven crater
polar acorn
#

That also doesn't make sense

#

that's a scene object being a child object of a file on disc

woven crater
#

to have follow movement?

polar acorn
#

A prefab doesn't move

#

because it doesn't exist

#

Having a scene object be a child of a prefab makes no sense

woven crater
#

ahhh i see what you mean now

#

lol

https://youtu.be/v1UGTTeQzbo?t=28 hey friends, im having a gander at this vid and in it, the person is giving his enemies each thier own canvas so they can display thier own health bars. I was under the impression giving individual objects their own canvas was poor practise? can someone please advise

Actually, the bad practice is putting everything on the same canvas

rocky canyon
#

i believe it is. (UIs being updated and redrew all the time is why it would be taxing)
also I believe games recycle UI panels for in world characters and stuff like a pooling system where it only uses what it needs

#

i haven't seen many games with a huge amount of healthbars.. altho one game comes to mind specifically and its a simple 2d game with a huge amount of enemies and stuff going on.. and theres tons of healthbars

#

its a top down point and click battle shooter type game

zealous oxide
#

I'm guessing this only becomes a problem when you have hundreds/thousands of canvas' and elements on at the same time?

rocky canyon
#

id guess lower but ya, and ur logic..

#

how ur updating them

#

plays a role also

#

instantiate 100s of ur prefab with an empty canvas and see what the performance does.. go from there, same with a smaller number

My personal advice, after getting familiar with the basics and maybe making some of the Unity Learn projects or your own small projects, you could look into programming patterns and S.O.L.I.D architecture - its a bit more of an advanced topic, but I found just getting familiar with a few patterns helped bridge the abstract "I wanna make this cool thing" and "where do I begin in making this cool thing?", then maybe try to apply that to something like pong, breakout, small projects like that, though through trial and error you may find an approach that works well for your understanding and workflow

Is there a good reason why this math isn't working?
The code being print to console is this:
print("ammoInClip: " + ammoInClip + "\nclipCapacity: " + clipCapacity);
print(ammoInClip / clipCapacity);

so convert the ints into floats beforehand?

So I'm trying to reference my Paddle position to this Projectile script so I can get it's position... where am I going wrong?

image.png
#

I'm getting a null reference to the m_paddle but m_paddle does in fact exist

wintry quarry
dense root
#

How do I assign it?

#

Or what do I assign it to?

wintry quarry
#

to the paddle I would assume

#

make it public, not readonly, and drag+|drop

#

you know this by now

dense root
#

awesome, thanks

galaga1.gif
#

how do I "shoot" the projectiles?

#

Like grant them movement shooting up

teal viper
#

Set velocity or apply forcešŸ¤·ā€ā™‚ļø

polar acorn
#

Put a script on them that moves it

dense root
#

So I'm trying to apply force however I'm getting that null reference error again despite having a RigidBody2D attached to it. Oddly enough it disappears during play. What am I doing wrong here?

image.png image.png
#

Oh I think I need to give my prefab a rigidbody not the spawner

# 
if (Input.GetButtonDown("Fire1"))
{
    // Instantiate projectile at the position and rotation
    Instantiate(m_projectile, m_paddle.transform.position, Quaternion.identity);

    rb2D.AddForce(transform.up * thrust);
}

So I'm trying to apply force upwards but what's happening is that it's dropping down, any ideas?

modern oxide
#

If you didnā€™t do it you need a public rigid body save it in your script and drag that rigid body onto your script

dense root
#

Gravity is set to zero

image.png
modern oxide
#

Or [seralizefeild] if no other script is

#

Going to need it

dense root
#

I'm having trouble with AddForce now

summer stump
dense root
#

What's impulse mode? And thrust is set to 1, but I tried 10 with the same result of it just dropping down

teal viper
dense root
#

Yes

teal viper
#

Are you sure about that? Why are you spawning a projectile in the projectile script then?

dense root
#

Well this is the projectile spawner

#

It just generates projectiles upon click

#

Then I want to apply a force to it

teal viper
dense root
summer stump
#

Oh yeah, you aren't adding the force to the projectile

teal viper
summer stump
#

Instantiate returns a reference. Get the rigidbody from that

abstract finch
# 
        while (true)
        {
            transform.LookAt(target.position);
            transform.position += transform.forward * _followSpeedCurve.Evaluate(followSpeed / timeElapsed);
            timeElapsed += Time.deltaTime;
            yield return null;

        }```
How would I be able to get the followspeed to ramp up based on the curve of this coroutien?
wintry quarry
abstract finch
wintry quarry
#

it should be timeElapsed / duration

abstract finch
#

the thing is I dont have a duration in this case

wintry quarry
#

it would be the duration over which you want the acceleration to happen

abstract finch
#

I just want there to be a set speed rather than reach a destination wihtin x speed

wintry quarry
#

otherwise the curve makes no sense

#

it's not aboput reaching the destination

abstract finch
#

what about this? _followSpeed * _followSpeedCurve.Evaluate(timeElapsed)

wintry quarry
#

it's about reaching the top speed

#

no

#

timeElapsed / duration

wintry quarry
abstract finch
#

ahhh ok

#

alright ill try it again

wintry quarry
#

it's also unclear what the followSpeed variable is in that example

abstract finch
#

thats the speed of which the transform will move, well the base speed.

#

it gets modified based on the animationcurve

wintry quarry
#

so the curve is supposed to be a speed multiplier?

abstract finch
#

yes

#

oh i forgot to mention as to why i didnt use duration here but i see what it means, duration is the max value. I want the coroutine to keep going.

# 
        float maxCurveValue = 1;
        while (true)
        {
            transform.LookAt(target.position);
            transform.position += transform.forward * (followSpeed * _followSpeedCurve.Evaluate(timeElapsed / maxCurveValue));
            timeElapsed += Time.deltaTime;
            yield return null;
        }```
#

seems to be working, i want it to keep following until it collides to the target

wintry quarry
#

the coroutine is going to keep going forever because you have while(true)

abstract finch
#

yea i want it to keep going until it collides

wintry quarry
#

the duration in my example does nothing besides decide how long it takes to accelerate

#

that's what the duration is for

#

it's the time it takes to go from followSpeed to whatever the max at the end of the curve is

abstract finch
#

ahh i see

bright nexus
#

Hi, I had this issue yesterday, and I thought I could fix it by clamping the fall speed, although it is persisting. I would appreciate any help or information as to why this is occurting. Please ask if you need more information. Here is my current code https://paste.myst.rs/hi3j0h3a Thank you.

put the Instantiate call on the right side of an assignment operator

#

i think its like GetContent something

#

oh yeah that spawns it

#

into the world

ivory bobcat
# 
var instance = Instantiate(prefab);```
normal slate
#

how would you get the rigidbody from that

#

you do the getcontent method?

summer stump
wintry quarry
normal slate
#

Oh yeah component

summer stump
#

or spawn based on the rigidbody

# 
public Rigidbody prefab;
Rigidbody newRB = Instantiate(prefab);
wintry quarry
#

unless of course prefab IS a Rigidbody reference already

instance.GetComponent<Rigidbody>();

right?

Hmm no dice...

GameObject i think

#

GameObject instance = ...

summer stump
normal slate
#

oh okay

summer stump
dense root
summer stump
slender nymph
#

is the rigidbody kinematic

dense root
#

transform.up * thrust, no?

#

RB is dynamic

summer stump
normal slate
#

doesnt kinematic just make it not detect collisions?

summer stump
slender nymph
polar acorn
normal slate
#

oh so like it self will exert force on the object but wont be effecte by them?

summer stump
dense root
#

It might have something to do with it spawning directly on top of my player object

slender nymph
#

put it on a layer that does not collide with the player object

dense root
#

Thrust is 10f

slender nymph
#

also you probably want to use ForceMode2D.Impulse

summer stump
#

I was gonna say, you didn't do that yet

normal slate
#

what does that do?

#

oh i see

summer stump
normal slate
#

so adds the force instantly

summer stump
#

Oh ok, good good

dense root
#

Turned off my RB and my collider no dice

#

On the player object

summer stump
dense root
#

No no, on the player object.

normal slate
#

do both objects have colliders?

dense root
#

In case it was colliding with the projectile to test

summer stump
dense root
#

Yeah

normal slate
#

if its falling then just set gravity to 0 no?

dense root
#

I haven't tried impulse mode yet

#

Gravity is 0

normal slate
#

weird

#

are younot using deltatime?

#

time.deltatime*

slender nymph
#

do not multiply your forces by deltaTime

summer stump
normal slate
#

if its falling down... then it might be because thurst.up?

#

isnt that on y axis?

#

could thrust be making it negative somehow?

#

if you are working on 2d it would be forward i think right? but on 3d it would go up and down

#

sorry if i am making this worse lol i am trying to learn as well.

dense root
#

All good we're trying

summer stump
#

That actually is a good point about direction.
@dense root
Try this just in case:
instance.GetComponent<Rigidbody2D>().AddForce(Vector2.up * thrust);

#

That uses the world coordinates and wont be affected by any transform rotation

normal slate
#

might as well do Input.GetAxis("Vertical")?

summer stump
#

They are shooting a projectile

normal slate
#

Ohh i see

#

but then vector2.up wouldnt help no? isnt that just (0,1,0)?

#

i mean 0,1

dense root
#

It might help if I shoot a video of it all

summer stump
#

This is a galaga game. They hit a button and it shoots a projectile up from wherever they are

normal slate
#

hmm so it just goes up

#

ah okay

#

then yeah that should work weird

dense root
normal slate
#

wait no

#

you need to grab the ridgid body of the instantiated object no?

#

line 23

#

on start you are setting it to the original object

wintry quarry
normal slate
#

wait i am so confused

wintry quarry
#

and what ahppened to your instance variable?

summer stump
# dense root

What happened to the code we've been working on? This is not what you want at all

wintry quarry
#

And everything that was discussed above lol

normal slate
#

yeah lol

dense root
#

This?

if (Input.GetButtonDown("Fire1"))
{
    // Instantiate projectile at the position and rotation
    var instance = Instantiate(m_projectile, m_paddle.transform.position, Quaternion.identity);
    instance.GetComponent<Rigidbody2D>().AddForce(transform.up * thrust);
}
normal slate
#

yes

#

lmao

summer stump
wintry quarry
#

it should be an Impulse force too
