i hope you understand my english is not so good

[viral plank]

Okay, before assigning him any random position, why not, take it's current position and add x+5/x-5 etc?

I thought, you already have defined a random positions all over the map, or do you want them to be generated on a runtime basis?

[green anchor]

actually thats what i dont want . i dont want to generate random positions all over the map. as you said i want him to move x+5 and x-5

[viral plank]

I am sorry, I am not following it here, so where are you stuck at? At what point?

[green anchor]

okay i want my enemy to move x+5 and stop then flip and move x-10 from current position

[viral plank]

Okay. So, pseudo code would go something like this.

//Defining the target Position
Vector2 TargetPosition;

//At the start of the code initialize the TargetPosition(I would recommand inside the start method)
TargetPosition = new Vector2(this.transform.position.x + 5f, this.transform.position.y);

//Now inside update/fixedupdate/lateupdate whatever that you are using, simply check for it's position
if (Vector2.Distance(this.gameObject.transform.position, TargetPosition) > 0.2f)
        {
            has_Reached = false;
        }
        else
        {
            //Stop
            has_Reached = true;
        }

where has_Reached would be a local boolean to determine if it's reached or not.

Then perform your logic after that depending on to has_Reached == true or has_Reached == false/!has_Reached

[green anchor]

when distance is almost 0.2f has_Reached switches between true and false so fast

[viral plank]

Then try toggling the value a bit

since I don't know what exact scenario of your game is, I won't be able to give the pin-point figures.

Anyone wanna try to crack this nut?

• unity 2d
• i have function that makes the player dash by setting the velocity of the player to the unit vector pointing towards the mouse. The problem is that this dash does not have a consistent travel distance and im unsure why.
• i have tried a lot of simple fixes like moving lines around and making it to where you cannot change the player velocity with wasd during the dash time
  Ive also posted an image of the player’s rigidbody and script settings in case anybody wants to try to recreate the problem.
  Much appreciated!

[flint hollow]

Hey guys can someone lend a hand?

[flint hollow]

Maybe you could implement a distance feature

or something

like you can make the dash go a certain amount

[meager moat]

so more like a teleport?

[flint hollow]

kinda yea

its just an idea tho

[meager moat]

i thought about that but i was unsure of how to handle things like hitting walls i know i can use raycasting to figure out if you hit a wall early but not sure how to keep momentum if you hit it

[flint hollow]

hmmm

i think you should use "AddForce" rather then new vector2

[meager moat]

i was thinking that maybe the getmousebuttonup was bugging because i press it in between a frame and it does the dash for an extra frame?

[flint hollow]

also

use fixed update rather then just update

since your using physics

[meager moat]

i thought fixed update was janky with input

any way to mitigate that?

[flint hollow]

hmm

how so is it janky i never experienced that

like give an example

[knotty barn]

Some input relies on frame updates for their state

[meager moat]

ive heard about it not recording inputs because it was recorded in between update intervals and whatnot

[flint hollow]

hmm i see

[meager moat]

so interesting

[knotty barn]

Generally the ones that are along the lines of returns true if started holding on this frame

[meager moat]

fixed update DOES make the dash length consistent

but

it completely breaks any input

🤔

[flint hollow]

maybe unity new input system maybe a work around?

[knotty barn]

Getting input values should be fine

[flint hollow]

if you do experience the jankyness

[meager moat]

well its just that when i release the mouse button it doesnt do the dash half the time

more than half actually

[flint hollow]

maybe its how your getting the input

like instead of getkeydown

just put input.getkey

[meager moat]

well im using getMouseButtonUp(0)

[flint hollow]

wait wait

[meager moat]

well that will just execute the command every frame it sees the button being pressed which i dont want

[flint hollow]

ohh i see

[knotty barn]

Yea that input relies on frames for the "Up" state

[flint hollow]

yea

[knotty barn]

You can get the input in Update and consume it in FixedUpdate

[flint hollow]

would looking for a left click work?

[knotty barn]

Save the value in Update and reset it in FixedUpdate

[meager moat]

so like, scan for the values and then set the dashing boolean to true so that the command executes in fixedupdate?

[knotty barn]

Not if it's expressing a frame dependant state

[knotty barn]

Yes

[meager moat]

i was hoping to just move all of this to 2 void functions called dashStart() and dash()

but ill see what i can do

[flint hollow]

Good luck bro!

[meager moat]

that sounds really clunky though 🤔

[flint hollow]

i say take a break and just think about it

thats what i do

and the answer just hits me

[meager moat]

i slept on it, been at this problem about 2 days now

[flint hollow]

oh geez

yea just follow what danny said

and see if that helps

[meager moat]

im figuring a way to see how to do that

okay so like

it works

[flint hollow]

yea?

[meager moat]

it looks janky as hell in code but the dash is still responsive and consistent in length now

so screw it

thanks @knotty barn @flint hollow

[flint hollow]

glad it works!!!!

[meager moat]

hell yeah

[flint hollow]

im just struggling on why my cube suddenly jumps

i want it to be smooth

😭

im practicing a simple platformer

type game

[meager moat]

er

define suddenly

[flint hollow]

hmmm

like

when the player clicks w

the cube just shoots up into the air

then slowly goes back down

[meager moat]

increase the gravity of the rigid body on the player object

[flint hollow]

alright

[meager moat]

try like 3 instead of 1

[flint hollow]

alright

[timber bramble]

im trying to move an object from 1 place to another, but it just instantly teleport ther everytime

[turbid heart]

That’s because you’re immediately setting the position of the object

[turbid heart]

If this isnt physics based, look at MoveTowards
https://docs.unity3d.com/ScriptReference/Vector3.MoveTowards.html

[timber bramble]

@turbid heart thanks

[meager moat]

so im making a camera system for a 2d game that sets the camera position to the point in between the position of the mouse and the player, which this works.
im trying to smooth the movement so it doesnt feel so jerky. ive tried the lerp function and the SmoothDamp function but both result in the player object being jittery whenever i move.
https://paste.ofcode.org/VMsLXYKPGEJKsWJHLrRdGD - heres the script.
any ways to make the player object not jittery?

[turbid heart]

have you looked at this?
https://answers.unity.com/questions/353132/smoothdamp-causes-jitters.html

[meager moat]

er, no

ill look at it tho

thanks

[meager moat]

im not sure how to impliment this code in this solution

it says "Cannot implicitly convert type 'UnityEngine.RigidbodyInterpolation' to 'UnityEngine.RigidbodyInterpolation2D'. "

oh wait i read it closer

me dumb i think

[turbid heart]

I think they just put body.interpolation = RigidbodyInterpolation.Interpolate; after they get the reference to their rigidbody. body would be their rigidbody

[meager moat]

its because RigidbodyInterpolation and RigidbodyInterpolation2D are different

i think

i did that and it removed my error code

[turbid heart]

uh.. you did what? if you're using Rigidbody2D, then just change it to 2D

[meager moat]

yeah

i fixed it

[turbid heart]

does it jitter still?

[meager moat]

no

its smooth now

[turbid heart]

awesome

[meager moat]

good good!

thanks again bruv

[turbid heart]

glad I could help you solve something this time, haha

[meager moat]

i found the issue with the previous problem tho

[turbid heart]

oh, nice, what was it?

[meager moat]

and it had a solution that made me mad

i just had to put the function that actually handled the physics into FixedUpdate() instead of Update()

[turbid heart]

eh, what? I can't believe I missed that

[meager moat]

which makes me mad because it looks and feels really janky

[turbid heart]

which function was it?

[meager moat]

so i slapped the dash start and the dash into 2 functions, and whenever update detects the proper input, it runs dash start, which sets a boolean to true which allows fixedupdate to run the actual dash calculations

im bad at explaining

https://paste.ofcode.org/q7qB3XxabEaea6BeC5Y72i

heres what it looks like tho

[vagrant hatch]

how do I change the opacity of tiles in a tilemap at runtime?

[turbid heart]

seems like it's just SetColor
https://answers.unity.com/questions/1489692/how-can-i-change-the-alpha-of-a-tile-sprite.html

[vagrant hatch]

setcolor doesn't exist

on both the tiledata nor the tilemap

[turbid heart]

oh, so.. because you're setting velocity, that's why it needs to be in FixedUpdate? Okay 😮 I'm not sure because i dont use physics much. Honestly it scares me, haha, but good to know

[turbid heart]

odd, there's a doc here
https://docs.unity3d.com/ScriptReference/Tilemaps.Tilemap.SetColor.html

[vagrant hatch]

i tried tileData.color = color but that doesn't update for some reason

[turbid heart]

can you show me how you're trying to use tilemap's SetColor? Full disclosure, i've never used tilemap stuff in Unity

[meager moat]

i think it's because fixedupdate is used for physics calculations and stuff so yeah. it looks janky but it works so whatever!

[vagrant hatch]

oh figured out why it didn't exist: The GetTileData method gets a ITilemap rather than a Tilemap

and that interface doesn't have a SetColor method apparently

[turbid heart]

yeah it is, but didnt think "setting" a velocity wouldnt be "physics calculations" but I guess I was wrong 😄

[vagrant hatch]

but that still doesn't explain why this doesn't work

[meager moat]

it may be because of some janky timing things probably idk

[turbid heart]

it might be a "get only" thing. Sorry, no clue

[meager moat]

so im making a better pointer for my dash function

i want it to give the precise position the player object will end up, even getting shorter if it collides with a wall

i want to do this by tiling a " - " visual, so the the visual would look like " O - - - - - __ "

hard to explain that any better in my brain

but is there a way to do this? like adding a visual effect to a physics raycast?

[turbid heart]

line renderer perhaps
https://answers.unity.com/questions/1142318/making-raycast-line-visibld.html

[vagrant hatch]

no problem ill just continue trying things haha. the unity docs suck

[still tendon]

dude how did you change your color theme to that, mine looks like this and i hate it

[meager moat]

so is it improper to use body velocity when trying to make a proper momentum based aerial movement? whenever i try something it just ends up setting my speed very high

[snow willow]

If you want it to be realistic - control it via adding forces and torques only

[meager moat]

i see, so something like body.velocity += new Vector2(horizontalInput * speed, 0); for the base movement would look fine on the face value but that is actually a linear increase in speed with no limit, so im not exactly sure how to handle this 🤔

[snow willow]

You need to be a bit less... Mindless

Add your acceleration forces

But also add drag forces

Etc

What is the acceleration coming from?

Your player's Input obviously but in the lore of the game?

Is it a jetpack?

Basically add the force that whatever the propulsion system would add when it would add it

[meager moat]

legs :^)

[snow willow]

In the air?

[meager moat]

er good point, but for the sake of fluid controls i wanted to just get an aerial movement that was a smooth transition from left to right, think something like how minecraft aerial movement feels

[snow willow]

Creative mode Minecraft?

[meager moat]

i havent gotten anywhere design wise to think about how movement in air would work from any sort of game lore standpoint

[snow willow]

Creative mode Minecraft is essentially just god mode flying. Wouldn't bother with forces for that but you could just add force/velocity and clamp the magnitude afterwards

[meager moat]

all i need to figure out is, when the player object is in the air, they will have partial control over their direction, essentially adding a force in a specific direction until they reach their cap

so id need a hard limit on the aerial velocity if im using addforce?

[snow willow]

If you want a hard limit then yes

Alternative is to use a drag function that adds force opposite to the current velocity in a realistic way

That will lead to a natural soft speed limit

[meager moat]

i see i see

[meager moat]

im trying to do something like this for the ground so i can allow the player object to slide if they hit the ground at a high velocity

but im left with a problem of like, when the object goes from stationary to moving, there is a delay

[vagrant hatch]

haha i made the theme myself

here's the link :) https://marketplace.visualstudio.com/items?itemName=Al3xCubed.theme-cubed

[still tendon]

thanks, definitely got another download

[vagrant hatch]

hmm, so OverlapCircle doesn't seem to work when I add a layer mask. Any ideas why?

wtf?

oooh

figured out why

had to do 1 << deathLayer since deathLayer is the index of layer, not the mask

[green anchor]

how do i declare (my starting position + 5). (i want to move my enemy to + 5 or -5 from his starting position)

[viral plank]

Declare Vector2 startPostion at the top of your code, where all of your variables are situated.

Now in the start method(assuming this script is attached to enemy gameobject)
startPostion = this.gameObject.transform.position;

now change the startPosition as per your wish. where startPostion.x is horizontal position and startPosition.Y is vertical

so if you want it to move to right, startPosition.x = startPosition.x + 5f this.gameObject.transform.position = (Vector3)startPosition

Kindly check for any compiling error, since I am not on unity/VS at the moment. I just wrote that code in a notepad.

[still tendon]

hey there

can someone help me?

i am trying to create gravity in my game and this error shows up

[turbid heart]

gravity doesn’t exist in your script. Are you just trying to change the entire physics gravity, or is it meant to be a variable you declare?

[still tendon]

varible

[turbid heart]

Then declare it in the correct scope

Where are you declaring gravity right now?

Ooops i just realised that was velocity

But yeah, where are you declaring velocity?

[frozen moat]

is the variable in other script?

[turbid heart]

Ignore that question. Their issue has been resolved and this was a crosspost 😒

[marsh oar]

hello, is there any way to make this code jump only when the player is on the ground, maybe a ground check? if you have any answers, please tell me cause im getting desperate

also, i tried mathf.clamp, it doesn't work

[elder minnow]

Check on YouTube how to raycast in Unity, the idea is that you use it to check how close you are to the ground. If you are within a certain range, it means you are grounded, thus, allowing you to skip the jump logic.

Box/circle casting works too

[marsh oar]

ok, i'll check it out, thx

[mossy canyon]

I've set the pivot point for a sprite in the Sprite Editor. I drag the sprite into my scene, but the the pivot seems to be dead center. What am I doing wrong? (The gameobject also behaves as if the pivot is in the center.. i.e my character goes "behind" a tree as soon as the center reaches)

[ebon flare]

Is there a 2D equivalent to Transform.forward? Any way to get a vector representing the direction the GameObject is facing in world space? Or am I better off just using the eulerAngles.z?

[calm wyvern]

Transform.forward is just the direction of the objects Z axis
there is Transform.right for the x axis
and Transform.up for the y axis
you will have to see what axis fits for your 2D case

[timber bramble]

i have a situation where my character/player is slow/delay to respond on jump as i press space bar, is there a way to improve this?

[modest marsh]

collect your input state inside Update, and apply non-instant forces inside FixedUpdate

[scenic hatch]

Hello! I have a question, if I have a character who is burrowing in the ground and I want them to ricochet off of the wall surrounding the sand, How might I go about doing that?

just for clarity, I am talking about something like this

[delicate path]

Is anyone good with maths? I'm trying to create a "StairZone" that gets an angle /_ from a polygoncollider2d[0] and [1] points, then figures out how much Y to add or subtract as the player moves thru it..but thats beyond my maths

Or... just a better way to do this lol

i wanna be able to slap this on any stairs, setup the collider and have it work for different steepness

[sudden knot]

Im new but for the math part, im pretty sure you can use height of stair / horizontal length of the stair

Then u can add/subtract the y postion of the player with that value

Oh wait you are trying to figure it out using an angle

[delicate path]

i don't need to use angle i suppose

just however

basically just what i should add to my y -- however i get there doesn't matter to me

[sudden knot]

Math wise, i think this is the simplest. I cant say much bout programming side cuz im pretty new

[delicate path]

height divided by horizontal length?

i'll try it, thanks

[sudden knot]

Just use (point1.y - point0.y)/(point1.x-point0.x)

[delicate path]

i had to use (point1.y - point0.y)/(point1.x-point0.x) and then divide the total by 5 (why?) but it works! thanks @sudden knot

[sudden knot]

I dont think you need to divide it by 5, maybe its something related to worldspace or local position, im not too sure bout it. But glad to hear that it works

[mossy canyon]

I have an "action bar" with a grid layout group, where I have added 5 2d sprites. When I drag an image into the sprite, it appears tiny. When I start the game, it's not even visible. How can I make the image/sprite stretch to the boundaries given by the grid group?

[fleet pasture]

Hey guys! im looking for a word processor for unity. Is there something out there or should I do it myself from scratch? thank you in advance!
I'm creating a note-taking app in case the reason for my question is needed.

I have started creating my own one using TMP but i feel that there should be something out there maybe.

[green anchor]

do you guys have any idea how can i exit from if statement. i tried to add my position 0.1f but still cant get out of if statement

[late viper]

use > instead of >=

[plush geyser]

Hello, I have a problem with my tic tac toe Game. When I press a field, X and O (the pictures) are invisible but it shows that this field has a value. Can someone help me, please? (dm for more information iguess)

[green anchor]

nothing changes

[late viper]

even if you do that on both if statements?

[humble obsidian]

wdym by exit it

is this all in a while loop?

[green anchor]

i did but imagine like this. my transform.position.x = 10 and my startposition.x = 15

no

[humble obsidian]

also if you want to handle something like this I suggest handling it differently

[green anchor]

let me tell you what i really want to do

[humble obsidian]

you dont want to check if the position is the same, you want to check if the distance is > 0

[green anchor]

i want to make my enemy move his starting position + 5 to right

[humble obsidian]

so run that code as long as the distance between the 2 positions is > 0.05f or something

[green anchor]

when he went + 5 stop and go - 5 from his starting position to left

[humble obsidian]

so you want it to patrol an area?

[green anchor]

yes

[humble obsidian]

couldve just said that lol

and whats the prob

its just infinitely going in some direction?

[green anchor]

no. never get out of first if statement

never checks else if

i cant get out from if statement when my enemy reaches startingposition

that statement is always true

[late viper]

well yeah, because you never change the position beyond that

you need to rethink the logic a bit

[humble obsidian]

do what i said earlier

patrol the area based on the distance from the starting point

then when the distance is greater than some number you can flip directions

you dont need Vector2.MoveTowards in this case at all if youre just moving left and right

[late viper]

if you want to stick to move towards you can do:

1. move towards start position + 5
2. check if position >= start position + 5
3. move towards start position - 5
4. check if position <= start position - 5
5. repeat from step 1

[green anchor]

i think i found the problem. i exit that if but when i start to move left first if becomes true

[late viper]

yes, thats why we're telling you to rework it 🙂

[green anchor]

this works very well!

[wide remnant]

I'm going to try to recreate https://www.nitrome.com/html5-games/badicecream/
I can probably create most of it myself, but I have no idea where to start when creating player movement that's restricted to a grid.

Ping me when you answer, i'm going to bed

[burnt badge]

im getting a wierd issue where niether tranform.position, nor localPosition are showing the same numbers as the the ones in the inspector

[late viper]

the position the rectTransform shows is based on the anchor, its not the position of the Gameobject itself

[burnt badge]

Ok, well since the anchor is controlled by the group layout, what syntax do i use if i want to get its starting position?

Or do i just have to do the calculations manually?

[late viper]

it'll just be transform.position

oh wait did you mean the anchored position? then its anchoredPosition3D

or anchoredPosition (gives you the Vector2)

[burnt badge]

Gotcha, thanks reo

[mossy canyon]

The blue lightning in this image is an animation. My game is currently paused. When the game plays, this animation is invisible. What could be causing that?

[burnt badge]

Hey, sorry for the late reply, but anchoredPosition still doesnt give me the same position as the inspector

[late viper]

https://docs.unity3d.com/ScriptReference/RectTransform-anchoredPosition.html
Note: The Inspector changes which properties are exposed based on which anchor preset is in use.

[burnt badge]

ok, well is it possible to access that exposed property through code?

[late viper]

my impression was that anchoredPosition would update it accordingly but I guess that's not true

you may have to just calculate it based on the offset/pivot

[burnt badge]

in the start() function ive printed the position, localposition, and anchroed position, and none of them match up with the inspector

im just trying to make a ui object go up when you hover your mouse over it, and then back down when its off of it. to do this, i need to save its starting position to go back to once the mouse is off of it. but for some reason unity is making it difficult to access that information

[late viper]

could you just ignore the values in the inspector then? if you just want to move it up you can just use any of the positions and add to the y component

[burnt badge]

well i want it to be a smooth transition so im using lerp. but the inspector is saying its at 250, -150, but since unity thinks its transform.position is at 0,0, its gonna lerp to 0,0. I dont see how i could lerp it up without using its transform.position.y

[sudden knot]

^ You can do this.You can have a variable called targetPos and set it to the transform of the gameobject you want to move and add it by the amount you want it to move up

[late viper]

yeah, if you just offset it using the position you grab in code, it shouldn't matter what the inspector values are because unity will still lerp it by the same amount

[burnt badge]

i dont think i understand. you mean literally like, targetPos = transform, targetPos+=7?

[sudden knot]

Yea the logic is correct but you can do it like this. Im new so i might not get the names right. But you can do this

Vector2 targetPos = transform + Vector2.up * [amount you want it to go up by]

[burnt badge]

ok, but the problem is i want it to be a smooth transition using the Vector2.Lerp function
right now im testing it by doing this:
startPosition = transform.position
transform.position = Vector2.Lerp(transform.position, startPosition, raiseSpeed*Time.deltaTime);
as you can see, in this situation im Lerping it from its position, to its position, and thats making it move for some reason.

[sudden knot]

i guess its the worldspace value and the local position value problem, this is just a newbie guess tho

Vector2 targetPos = transform.position + Vector2.up * [amount you want it to go up by]
transform.position = Vector2.Lerp(transform.position, targetPos, raiseSpeed*Time.deltaTime);

just use this

[burnt badge]

it considers its transform.position as a vector3, so i cant add a vector3 and a vector2

[sudden knot]

oh change it to Vector3 then lol

there should be a vector3.up

[burnt badge]

ok, implimented that, it does not go up

it goes up and to the left

waaaay away

[still tendon]

와 한국인 없냐

겁나 홀로 있는 기분이야

[sudden knot]

i have no idea why it goes left

[late viper]

one reason might be because you're not using lerp quite correctly

A quick guide to Lerp~✨

Lerp is used to blend between two things!

It has three inputs: ( a, b, t )
a = start value
b = end value
t = how far we should go from start to end, as a percentage

Here it is in action!⚡blending a value, position, color and an angle! https://t.co/LdA69fLI8N

[burnt badge]

thats how ive been using lerp this whole time

to move an object smoothly between itself and another point

[burnt badge]

thats where the difference between what unity thinks its poition is, and what the inspector shows its position as, i believe

because unity thinks its at 3,0, so if the inspector says its at 200,150, its gonna go to the left

[sudden knot]

that shouldnt happen since it is just the offset

[late viper]

yes, the inspector values should not matter

[sudden knot]

the only thing that i think could go wrong is that you typed something else instead of Vector3.up

[late viper]

try doing it using the anchoredPosition instead

[burnt badge]

trying now

[late viper]

also the "proper" way to use lerp

//declare a float t somewhere at the start of the class
Vector3 startPos = transform.position;
Vector3 targetPos = transform.position + [offset]
transform.position = Vector2.Lerp(startPos, targetPos, t);
t += Time.deltaTime;

ah fuck I don't remember how to format code lmao

[burnt badge]

uhhh its not letting me send messages

[sudden knot]

your message/code is probably too long

[late viper]

yeah i figured it out, its just not highlighting anything because none of it is native c# stuff

[burnt badge]

oh hey, it unmuted me. ill send my code blocks using pastebin from now on

anyways, heres the code im currently running:
https://pastebin.com/yi0nkvU7

[late viper]

you should do it in Update() since its not physics

also why are you changing the localPosition?

[burnt badge]

oh right, lemme do that real quick

and just testing, ive tried it with both position and localposition, both result in going up and to the left

[late viper]

what happens when you use anchoredPosition?

[burnt badge]

still up and to the left, but faster

same thing that happens if i use localposition

[late viper]

could you post the whole script? use https://paste.ofcode.org/ for highlighting

[burnt badge]

https://paste.ofcode.org/39AsemmzffDNu2Uvd3ix6aW

forgot to change it to fixedUpdate, did that jus tnow

[late viper]

when I said use anchoredPosition, I mean change all instances of transform.position to anchoredPosition

otherwise its not going to work

[burnt badge]

i see, implimenting that hnow

[late viper]

im surprised your lerp works btw, you're giving a vector2 lerp vector3s

[burnt badge]

yeah, this is my first project with unity, its real silly how it handles that

[late viper]

don't use GetComponent in update, save it to a local variable first

[burnt badge]

gotcha

I printed the targetPos, and its set to (0,10). and the position in the inspector seems to be moving towards 0,10

ok, so the inspector shows the position to be (400, -150), so i tried setting the targetPos to (400, -100), and it started moving directly up

so then, if we could just figure out how to get the position that the inspector is showing, i can just add my raise height to its y component, and set that as the targetPos

but, thats the original problem, position, localPosition, nor anchoredPosition give the same position that is shown on the inspector

[late viper]

is your object parented to something?

[burnt badge]

a text object

[late viper]

whats its position?

[burnt badge]

of the text object? 0,-40

[late viper]

gtg for a bit but I'll be back, this is quite the head scratcher

[burnt badge]

sure thing, i appreciate your time man. hopefully i can figure this out in the meantime

this is suuuuuuuuper wierd

i tried printing the RectTransform.anchoredPosition as it lerped

when printing its RectTransform.anchoredPosition from the Start(), it reads 0,0
but, on the first update frame, after lerping once, it goes to 0.4, -0.1
then in the next frame, it shoots to 400, -150,, which is where the ihnspector showed its position originally

from then on, its y position goes up like it normally would through lerping

i gotta admit, i think this ones on unity. ive been doing more testing, and it seems like its only getting its TRUE RectTransform.anchoredPosition in Update()

for instance, this code makes it go up and to the left: https://paste.ofcode.org/nqzG5VYyEhz3sE37wuSiWb
but THIS code makes it go DIRECTLY up, no x movement: https://paste.ofcode.org/3wAhpEuA4AyePtGZsyicqb

another test. i tried making the first 2 frames of Update() a sort of psuedo Start(): https://paste.ofcode.org/Sg8Rn3brGhjjtYxkkHmcDG

and heres the two prints that came from it:

so i dont know wtf is going on man, this is the wierdest thing ive seen so far using unity

[meager moat]

so im using addforce to make my player object move from left to right, adding force in whatever direction the player is.
this has an unintended side effect of the controls feeling incredibly unresponsive due to the player having to accelerate to speed.
i tried to fix this by setting the velocity to the player's soft capped speed whenever they pressed one of the direction buttons, but for some reason this part is not working at all, any reason why?

 if (grounded())
        {
            if (Input.GetKeyDown(KeyCode.A) || Input.GetKeyDown(KeyCode.D))
            {
                body.velocity = new Vector2(horizontalInput * speed, body.velocity.y);
            }
            body.AddForce(new Vector2(horizontalInput * (speed), 0));
            if (body.velocity.x > speed)
            {
                Vector3 dragVel = body.velocity;
                dragVel.x = dragVel.x / (groundDrag*2 + 1f); // zero = no drag. Start with a small value like 0.05
                body.velocity = dragVel;
            }
            if (body.velocity.x < -speed) 
            {
                Vector3 dragVel = body.velocity;
                dragVel.x = dragVel.x / (groundDrag*2 + 1f); // zero = no drag. Start with a small value like 0.05
                body.velocity = dragVel;
            }
            dashAir = false;
        }```

[late viper]

Wow that is dumb. Are you doing anything to the object before you run this script? If not I guess it's a unity bug

[burnt badge]

i do have it already in play before runtime. having it be in a viewport might be screwing with the position before it fully initializes. other than that tho idk

thats just for testing pourposes, ingame, the object will be added proceduraly, so that might fix the error before it becomes a problem

[hollow crown]

the canvas scaler (and/or canvas) probably just hasn't run before that point

if you made your script execute late it may work. There are also some callbacks to look into. UGUI is painful to work with

[burnt badge]

execute late is in using LastUpdate, or is there anohter method to achieve that?

[hollow crown]

as in script execution order

it may not help at all in this case though. I've spent many an hour fighting with UGUI

[burnt badge]

How do i make some scripts execute last in order?

[hollow crown]

https://docs.unity3d.com/Manual/class-MonoManager.html

use it sparingly

Noted, thank you for the info.

[subtle geyser]

Trying to implement some basic pathfinding using 2D tilemaps and came across this github example: https://github.com/pixelfac/2D-Astar-Pathfinding-in-Unity

This seems straightforward enough but the way he's trying to access components seems a bit unweildy..

"object_name".GetComponent<Pathfinding2D>()."gridowner_name".GetComponent<Grid2D>().path[0].worldPosition;

seeker.transform.position = seeker.GetComponent<Pathfinding2D>().GridOwner.GetComponent<Grid2D>().path[0].worldPosition;

Could someone suggest a more efficient way of doing this? Been struggling to find a good implementation of something like this and I feel like this will do what I need it to but can't seem to get this working..

Open to other suggestions as I'm looking for just a basic 2d tilemap pathfinding where enemies move one tile at a time towards the player.

[meager moat]

so i have this in my update function

    private void Update()
    {
        // gets a 1 or -1 based on if a or d is pressed
        horizontalInput = Input.GetAxis("Horizontal");
        // gets a 1 or -1 based on if w or s is pressed
        verticalInput = Input.GetAxis("Vertical");
    }```
and im not sure why but ``FixedUpdate`` does not see this change when i try to use these values

am i missing something

[turbid heart]

you mean code that runs in FixedUpdate that use horizontalInput/verticalInput dont seem to react to those variables?

[meager moat]

yeah,

    private void FixedUpdate()
    {
        if (grounded())
        {
            body.AddForce(new Vector2(horizontalInput * (speed), 0));
        }
    }

i tried using debug to see what the value of horizontalInput was and it only returned 0

[turbid heart]

can you try Debug.Logging horiontalInput inside that if statement and see if the values are actually changing?

oof

does it change inside Update?

[meager moat]

yes

maybe fixedupdate isnt calling because there are no physics calculations starting yet?

[turbid heart]

if it isnt calling, you wouldnt see it print 0 😮

horizontalInput and verticalInput are declared outside of Update, right?

[meager moat]

yes

[abstract olive]

This probably has nothing to do with any of this, and instead the fact your grounded check is just false.

Debug log inside that statement to see if it's even true at any point.

[turbid heart]

yeah.. where exactly did you try to print horizontalInput in FixedUpdate?

[meager moat]

the line of code right after the addforce command

something even weirder

my jump key works and when im in the air this function does in fact work fine

if (!grounded())
        {
            body.AddForce(new Vector2(horizontalInput * (speed), 0));

wait ill try to put the debug there too

[meager moat]

it records the change when the player object is not grounded

[turbid heart]

is your input detection inside any sort of if statement that stops it from assigning your input variables?

[meager moat]

no

so i just replaced body.addforce

with body.velocity

and it works perfectly fine

[turbid heart]

um.. okay XD your issues always confuse me, haha. glad you got it figured out

[meager moat]

yeah my issues are really weird

i havent figured it out yet though

body.addforce not working is still. not good

bro im giga confused this is weird as heck

i think it's a mass thing

[meager moat]

it was

now i need to figure out how to properly slow down the player quickly and smoothly

So im following a tutorial but it wont let me place the tile infront of the background can anyone help?

the arrow points at where it will let me place but when i hover over a tile on the background the object disapears

Is it possible that the tiles are below the background?
Try moving its position

[remote moth]

i get a nullreference error by set a interger

a.GetComponent<Slot>().ID = i;

public int ID;

for (int i = 0; i < size; i++)

[snow willow]

a doesn't have a Slot component on it

so GetComponent is returning null

and you're trying to set ID of null to something

[remote moth]

wait

GameObject a = Instantiate(Slot) as GameObject;

oh right

[snow willow]

that's different

[remote moth]

ik

[snow willow]

There's the Slot component type, and then there's your Slot variable 🙂

[remote moth]

but bevor has it worked

[snow willow]

a doesn't have a Slot component on it. Up to you to figure out why that is ¯_(ツ)_/¯

[remote moth]

i has deleted the prefabs on the right sideline, and then was all prefabs diselected

[remote moth]

ik, i fix it

[sand wing]

How would I go about locking a camera horizontally, but have it follow something vertically?

[snow willow]

Just set the y position of the camera to equal the y position of the target

and ignore the x

Or follow a proxy object that does that

[sand wing]

ah... thats really simple why didnt i think of that. ok, ty!

[ruby wadi]

My enemy facing the wrong direction

[teal lily]

private void OnCollisionEnter2D(Collision2D collision)
    {
        if(collision.collider.tag == "Player")
        {
            Physics2D.IgnoreCollision(GetComponent<Collider2D>(), collision.collider);
            Instantiate(grasseffect, transform.position, Quaternion.identity);
        }
    }

so basically i always want to spawn grasseffect when the player walks into the collider of the grass, the problem is that it only works on the first ever collision but not on the next ones why is that? is it because of the ignorecollision line?

i still want the player to be able to be in the grass

[sand wing]

i think it's because it only occurs when you enter the collision, and not on the frames after that initial collision. i had a similar bug where if the player jumped but did not stop colliding (because the jump did not cause the player to go up any) with the floor, then they did not get their jump back.

[teal lily]

so ontriggerenter is the right method for this?

ooooohh

How to make a simple animation when I press a button?
Basically when I press "K" on my keyboard, my player will make a shoot animation.

[turbid heart]

first you need to know how to detect when the K key is pressed. the you need to have an animation already created and an animator set up. then you find out how to play the animation

        directionToTarget.x = startPos.x == targetPos.x ? 0 : targetPos.x > startPos.x ? 1 : -1;
        directionToTarget.y = startPos.y == targetPos.y ? 0 : targetPos.y > startPos.y ? 1 : -1;

        return directionToTarget;

Trying to move objects along cardinal directions in a 2D grid but my current code is causing some weird behavior...

Two things I'm hoping to achieve:

1. Prevent diagonal movement (ideally I'd love to be able to toggle to allow either cardinal only or diagonal only but if I can only easily have one it would be cardinal)

2. If there is an obstacle between the enemy and the player, rather than having the enemy keep trying to move into the obstacle, to pick a new direction at random on it's opposing orientation (i.e. if it moves down and hits an obstacle, randomly choose between left and right)

I realize A* would probably solve the latter issue but that seems overkill for what I'm trying achieve as I really only need basic cardinal movement for objects.

[rough yarrow]

You are changing both directionToTarget.x and .y at the same time, meaning that sometimes it will actually move diagonally. You'll need to check if you've moved in either direction, and not apply the other direction if you have. This would probably make it biast to moving either horizontal or vertical first, but you could alternate each position update as an example.

[timber bramble]

im trying to make an option move according to set distance, then back

but upon running the code

it just shake violently when it reached its max range

as if code are fighting to move < and >

[turbid heart]

you can confirm this with Debug Logs in your if statements. but see if this is relevant
#💻┃code-beginner message

also in the future please use a paste site. see the pinned messages in #💻┃code-beginner on how to post code here

[timber bramble]

eh

is there an operator to flip a value from positive to negative

or negative to position?

[turbid heart]

multiply it by -1

[leaden sky]

How do I fix the bullet "jumping" over the wall? The bullet has rigidbody2d and capsule collider. It gets a velocity at the start. Theoreticaly I could do the walls thicker but I want this to work against moving ships as well.

[lean estuary]

If the bullet travels in one frame faster than the width of the collider it will end up outside. Continuous collision might not handle some cases as well. In that case you want to raycast each frame and cache information, so if your bullet ends up outside, you can use information from previous frame to correct its position and travel direction.

[leaden sky]

cache what is in front and what is behind the bullet? Will that work for the enemiesi as well?

[lean estuary]

cache the previous raycast, it will have a collision location (and previous bullet position)

[knotty barn]

Would continuous collision not be able to deal with this case 🤔

Does it ever hit the wall?

[lean estuary]

Long time ago working on breakout type game I think I've had cases it going so fast continuous wasn't working properly too

[leaden sky]

I thought continous would do it. And yes,most of them do hit the wall

[leaden sky]

dont understand. Ok so I cache what was in front. Do I just compare that and if it is behind the bullet now its a missed collission?

[lean estuary]

Once bullet is outside of the game space, you use last raycast point to place the object there instead. And use raycast vector with hit angle to calculate proper ricochet, I think there's a bult in method for that as well

(and use resulting ricochet angle to set new velocity direction)

[leaden sky]

yeah so the bullit is suppose to be destroyed on impact. But should work on more than just the walls. Ideally you awnt to hit an enemy 🙂

[lean estuary]

even simpler, just register when it is outside

[leaden sky]

for the walls yes, but not for enemies

[lean estuary]

raycast should be the length of velocity so you can tell if it hit something, in this case hit something next frame when raycast says you are about to hit it

[leaden sky]

what if an enemy moves at the same time. So raycast sees the enemy but the next frame the enemy has move and didn't actually get hit?

[lean estuary]

Default frame is 1/50 of a second

[leaden sky]

so just ignore that very small possibility?

[lean estuary]

If you want more detailed calculation you can easily calculate it with object and bullet speed at that frame as well

[leaden sky]

but with a raycast that looks at the range of the speed, do I even need collission detection/OnTriggerEnter ?

[leaden sky]

Something like this then. It seem to work at least

[lean estuary]

You are not caching raycast, bullet will be destroyed just closing in to the wall. You can also use Debug.DrawRay or line to visualize raycasts, travel path. Also you should use velocity as raycast direction.

[leaden sky]

sorry don't understand why I need to cache it. If it is going to hit in this fixedupdateframe (I suppose the move is done later in the frame) then it should die this frame? I dont want it to bypass the wall and get destroyed on the other side of the wall /enemy

[lean estuary]

When you raycast it, it hasn't hit yet. When you hit and go past then you need to use information

(previously cached)

[leaden sky]

so if the backwardraycast hits withing velocity range and the frame before the same object was hit with teh forward raycast+

[lean estuary]

if you raycast back you may get another object entirely

[leaden sky]

?

but the raycast hit is limited by the velocity so won't it hit this frame?

and if I raycast forward next frame, I might have skipped it? and raycast will return empty?

[lean estuary]

velocity is per second so should be cut by 50 to be per frame

it will also ensure that you are looking at actual data, if you have gravity or drag affecting it

[leaden sky]

gravity and drag is set to 0

and it seem to be able to skip the wall

the ray is drawn from the transform.position which shows this

[cerulean lily]

hi, why the code lice StartCourotine or SerializedField doesnt light up in my vs? do i need to install some sort of module or something?

and heres the errors

[leaden sky]

its misspelled

StartCoroutine

[cerulean lily]

oh ok, but still, it didnt light up even when i started writing start

or just corrected me

[lean estuary]

@cerulean lily You need to setup VS to work with Unity. Configuration guide pinned in #💻┃code-beginner

[cerulean lily]

oh sorry

ill do that

[leaden sky]

am I doing it wrong or is a drawing problem. My debug draw shown the wrong way (or it's just last frames debug arrow)

should point up left

the bullet can still go through my wall

[lean estuary]

You need to use Rigidbody position instead

Transform is not part of physics

[leaden sky]

ohh I see. and apparently I am colliding with myself as well 🙂

I just did only find example of raycast using transform.position

[leaden sky]

so didn't quite get it but can I get my bullet to actually move to the colliding position instead of overshoot?

[lean estuary]

Like I said previously, once you overshoot you move it back to collision position yourself using cached raycast hitpoint.

It will be almost the same as if physics caught collision correctly

[leaden sky]

and I know if it overshoots when the forward raycast different from the wall?

[lean estuary]

you know it overshot when cashed raycast says there was a collision when it didn't happen

[leaden sky]

OnTriggerEnter2D is after fixedupdate right?

[lean estuary]

https://docs.unity3d.com/Manual/ExecutionOrder.html

[leaden sky]

so frame 1 I find a raycast collission.
on frame 2. we have now overshot the target and no raycast is detected so we think no detection is made because it will be found later in the execution order

[lean estuary]

At this point you don't need collision even really, just check cashed raycast every frame. Or you can use coroutine to yield until FixedUpdate finishes and check then if collision happened.

[leaden sky]

yeah, my thought exactly. As soon as a cached one existing. Move it back and destroy it.
Thank you very much.

[leaden sky]

Sorry another small question. I try to reset the position so the graphic will update correctly. Atm it will be rendered (very briefly) on the wrong side of the wall. I try to force it back.

[lean estuary]

It shouldn't be rendered inside the wall, as it should be moved on the same frame right away, then rendered

[leaden sky]

wrong side of the wall

[lean estuary]

you should be yielding to end of frame

[thorn echo]

is there something i can to reduce the delay between sound play and the object being destroyed?

[lean estuary]

Check that you are moving to the correct point

[leaden sky]

was directed towards me

and yes the point is correct

[thorn echo]

This is how the code is working rn

[leaden sky]

I have tried by just disabling fixedupdate as soon as the object dies instead of destroy

[lean estuary]

Print out the positions

[leaden sky]

these are the positions I set them to. So for a split of a second its on the other side and then reversed back to lock onto these positions which looks good

[lean estuary]

Use step forward on pause in editor, printing out position to see what's happening

Maybe previous hit raycast is too short

it should show anomalies step by step

[leaden sky]

I havent used that before

[lean estuary]

You are running a loop waiting for the sound to finish playing, you don't need to do that.

[lean estuary]

For simplicity start shooting on play, press pause, then play, then go step by step

[leaden sky]

so this is 1 frame after collission was warned by the raycast. So the cache is set

[thorn echo]

so should i remove the while function is that it

[lean estuary]

yes

Removing that you don't need it to be a couroutine as well, so replace IEnumerator with void to return nothing

[thorn echo]

ohk

Error - audiosource.isplaying can not be used like a method

[turbid heart]

dont use it like a method then. that means dont put () after it

[lean estuary]

Inspect values raycast has, if it points to correct position at this point

[thorn echo]

already did that, or should i remove semi colon too

[turbid heart]

it's a bool type https://docs.unity3d.com/ScriptReference/AudioSource-isPlaying.html

[lean estuary]

You need to remove entire thing, not just only while

all that is contains

[thorn echo]

ohk

but if i remove the loop the sounds won't play it destroys as soon as player collides with the object which any sound

[leaden sky]

yeah this has not yet found anything from the raycast.

[lean estuary]

This looks like a correct case

[lean estuary]

don't put stuff you need to play on things you are destroying.

Use a sound manager and make it play on event

[thorn echo]

ohk i just found sound manager a little hassle 😅
Thanks for the help

[lean estuary]

Alternatively you can make it just invisible, and then collect to the pool. But having central manager would be better in any case.

[thorn echo]

i get it now, Thanks

[leaden sky]

@lean estuary I put the raycasting WaitForFixed update and it looks great

it was raycasting because having its physics position updated I believe. So the raycast was from previous tick position

[rocky temple]

heya I'm trying to make a collider a trigger from inside a script I've tried a couple of things but they don't seem to be working any tips?

[abstract olive]

Yeah, show your code. 😛

[abstract olive]

It's adding the SpriteRenderer, but not the Collider?

[rocky temple]

it added the collider perfectly fine I just don't know how to make it a trigger

[abstract olive]

Any property you see in the inspector can by changed like how you were doing it with the .sprite

In this case, you would use .isTrigger = true;

ohh I got it now

tyvm 😄

[worldly reef]

I am working on a topdown game right now where the player can recall a projectile and then launch it around the map. I'm running into an issue where at high speed, the projectile gets stuck in walls. I am manually adjusting transform.position because I don't feel like messing with physics and I think it gives the result I want better. I have detections sent to continous and have decreased fixed timestep. That's all helped it happen less, but it's still a problem. I also write a OnColissionStay2D that bumps the projectile out when it gets stuck, but it's does not really fix the problem and doesn't look great. Anyone have any other ideas for fixing this and keeping my existing movement?

[remote moth]

whats the best way to save and load GameObjects and data?

[worldly reef]

There's lot of different ways to go about it. The simplest way to store some data would be PlayerPrefs

[worldly cove]

I'm having trouble destroying an instantiated game object. When I pause the playback, I can see that the cloned object still exists in the hierarchy tab.

[remote moth]

and whats the best way to save a "chunk" (a object with a lot childs sorted by x value)?

[worldly reef]

I'm going to admit that's a bit beyond me, haha, but this should get you moving in the right direction: https://www.youtube.com/watch?v=XOjd_qU2Ido

[remote moth]

can i save the object in script as prefab, and to save override the prefab?

[worldly reef]

I don't know if that's possible, I've never tried. But doing some research, I just stumbled across this: https://docs.unity3d.com/ScriptReference/PrefabUtility.SaveAsPrefabAsset.html

Might be worth looking into

[remote moth]

and were can i load it?

So i can save, but loading

string localPath = "Assets/saves/chunks/" + save.name + ".prefab";
localPath = AssetDatabase.GenerateUniqueAssetPath(localPath);
PrefabUtility.SaveAsPrefabAssetAndConnect(save, localPath, InteractionMode.UserAction);

[worldly reef]

Can you save in the Resources folder and then use Resources.Load?

[remote moth]

yes i can, but i don't want to make it in the resource folder

i try LoadPrefabContents

when not i use Resources.Load

it exist only one problem

when it save, the game freeze a half second

can i do it in a thread?

[vast plume]

Hi i just made a 2d player controler and now i want to make a cameramovement thing it works but i dont know how i can do it so it stops moving at an certan point
How can i do this?

[remote moth]

why is "LoadChunk" everytime null?

private void SaveChunk(GameObject save){
  string localPath = "Assets/saves/chunks/" + save.name + ".prefab";
  localPath = AssetDatabase.GenerateUniqueAssetPath(localPath);
  PrefabUtility.SaveAsPrefabAssetAndConnect(save, localPath, InteractionMode.UserAction);
}

private GameObject LoadChunk(int num){
  string localPath = "Assets/saves/chunks/chunk " + num +".prefab";
  localPath = AssetDatabase.GenerateUniqueAssetPath(localPath);
  GameObject o = Selection.activeObject as GameObject; 
  if(o == null){
    return null;
  }
  return PrefabUtility.LoadPrefabContents(localPath);
}

[snow willow]

debug it.

maybe o is null or is not a GameObject

maybe LoadPrefabContents is returning null

maybe both at different times

[remote moth]

exist so any in unity?

[snow willow]

you can save your game in a thread but you have to be really careful about it. Background threads cannot access most Unity Engine objects/data

If you can succesfully isolate the data you need to save from referencing any of that, you can definitely do your saving in a background thread.

[remote moth]

and where is thenn the best way to save objects without lags

as prefarb

can i give the thread a paramenter

Thread thread = new Thread(
() =>{
  SaveChunk(d);
  Destroy(d);
  }
);

[remote moth]

but a lot things can i only do in the main thread?

[remote moth]

can i anything do becaus the error, or can't i do any with new threads to save the object

[deep urchin]

If I use OnCollisionEnter2D do both objects need to have a collider2D and a Rigidbody2D?

Or does just the object with the script need a Rigidbody?

[turbid heart]

Not sure, but you can easily test that with a Debug Log

[deep urchin]

ok

[remote moth]

if i do it with a ThreadPool exist no errors, but it not saved the object as Prefab (he don't execute the methode SaveChunk();

ThreadPool.QueueUserWorkItem(
  o => {   
    SaveChunk(c);
    Destroy(c);
  }
);

[rocky temple]

is there a way to find all objects with a certain tag and then set them all to not active?

[sudden wasp]

can someone here join a VC with me and explain the way to use layers in unity i am very confused, all the Youtube videos don't help

2d

Oh wrong chnneæ

channel

sry

[rocky temple]

figured out the answer to this (if someone looking at this has a similar problem DM me for what I used)

[snow willow]

just beware if you're using FindGameObjectsWithTag - that it will not work on the deactivated objects if you try to use the same thing to reactivate them

[rocky temple]

for what I'm doing I am using Destroy instead, I just wanna get rid of all of a certain game object when the game over screen activates

[deep urchin]

I am trying to get an object to face towards the mouse. Yesterday this script was working, but then I saved everything, re-opened it today and I got an error.
The error is NullReferenceException: Object reference not set to an instance of an object Here is the code:

Vector2 direction = (mouseScreenPosition - (Vector2)transform.position).normalized;
transform.up = direction;```What is the problem?

[late viper]

which line exactly do you get the error?

[snow willow]

DO you have an enabled camera in the scene with the tag "MainCamera"?

[deep urchin]

The error is on the first line Vector2 mouseScreenPosition...

[deep urchin]

No I didn't, I tagged it now and it works, thanks!

[deep urchin]

Completely different question, does OnCollisionEnter2D require a dynamic body type? Because If I set it to Kinematic it doesn't work, but I want it to be Kinematic so it isn't effected by physics.

[snow willow]

A kinematic rigidbody collider (kinematic RB with a collider) will only cause OnCollisionEnter with dynamic rigidbody colliders (dynamic rigidbody with a collider)

It won't collide with static colliders or other kinematic rigidbodies

(a static collider is an object that has a collider and no Rigidbody at all)

I got this chart from the bottom of this documentation page: https://docs.unity3d.com/Manual/CollidersOverview.html

[deep urchin]

Ok thanks

[snow willow]

The trigger matrix is a bit more forgiving

kinematic rigidbodies will cause trigger messages with any trigger collider

[deep urchin]

Doesn't that mean kinematic wont detect collision if it hits another kinematic?

[snow willow]

It won't cause a "Trigger" message if neither of them is a trigger collider

It will work if one of the two objects has a trigger collider

[deep urchin]

Do you mean this thing?

[snow willow]

yessir

that makes the collider intoa trigger collider

note that if you want to detect that in code it's a little different:

void OnTriggerEnter2D(Collider2D other) {

}```

[deep urchin]

Just get rid of private at the beginning?

Oh wait Its OnTriggerEnter instead of OnCollisionEnter

[snow willow]

yes and a different parameter type

Collider2D instead of Collision2D

[deep urchin]

Ok thx

[deep urchin]

Another completely different question, I tried using this script

{
        Destroy(gameObject);
        Destroy(collider);
}```to destroy both this object and the object it collides with, but it doesn't do that, It just destroys the object with the script. Is there anyway to destroy the object I collided into in the same script?

[forest hamlet]

Because you're destroying the gameobject that has the script before the object it's colliding with, thus it never reaches the second destroy call @deep urchin

It's like if someone said they were going to shoot themselves, then shoot someone else, they would never get to the second part because they were dead lol

[worldly reef]

On mobile so formatting going to be bad, but I think you want Destroy(collider.gameObject); Destroy(this.gameObject);

[forest hamlet]

oh yeah that too

[snow willow]

doesn't work this way. Destroy is delayed until the end of the frame

It's what Wrimor said

[deep urchin]

Yes, I did what Wirmor said and it works now

[snow willow]

the difference is destroying the whole other GameObject vs just destroying its Collider component

[deep urchin]

Yes

[split edge]

why does my 4k sprite look so bad on Unity?

it looks like an upscaled sprite

this is the original resolution

why would the game make it look like this

like I am completely blown away at why would Unity destroy this visually

[snow willow]

try disabling compression in the import settings

[split edge]

yeah, set to none

that was bilinear filtering btw, this is how it looks like in point

like

how

[late viper]

few things

[split edge]

mipmaps enabled, sprites arent a power of 2, I dont think i can meet that requirement

[late viper]

https://www.reddit.com/r/Unity3D/comments/9f86e1/downscaling_sprites_in_unity_gives_different/ from this post

[split edge]

Everyday I am more surprised at how shitty Unity is

[late viper]

it doesn't surprise me at this point 😄

[split edge]

like this isnt a crazy requirement

I am not even downscaling them

Love to wake up to see unity doesnt have a functional sprite renderer

[late viper]

i mean you're effectively downscaling them when you render them at that resolution

[snow willow]

I'm trying to figure out what you're expecting this to look lioke

is it the lack of antialiasing that's the issue?

[split edge]

it doesnt look like a 650x200 sprite scaled down, it looks like a 60x20 sprite scaled up

I guess this is better but thats trilinear filtering with a 16x anisotropic factor

for comparison, this is what a downscaled version should resemble

Is not like I am doing something crazy, my viewport target is 4k , these sprites should look as they are

[late viper]

unity's downscaling algo just isn't as good as gimp, according to the unity forum post https://forum.unity.com/threads/downscaling-sprites-in-unity-vs-image-editing-software.553807/#post-3669721

[hearty tiger]

I'm making a 2d sidescroller (orthographic camera), and have been using Z coordinates for sorting, however this is affecting sprite size and all collisions to an extent

How am I meant to sort objects?

[turbid heart]

Sorting layers. You’re meant to use that instead of relying on z

[hearty tiger]

ok thanks

should the higher numbered layers appear above the lower numbered layers?

does layerering depend on z position whatsoever if objects are on different layers?

[turbid heart]

Layering takes precedence over z sorting

[turbid heart]

Why dont you test? 🙂

[hearty tiger]

it wasnt working so i asked

but turns out i was looking at the layer of the gameobject

not the sprite renderer

[still tendon]

#Hello Everyone. I don't know what happened on this code line:

anim.SetFloat("speed", Mathf.Abs(movePlayerVector));

#It show the error result like this:

Help me!

[vocal condor]

anim is null?

[still tendon]

No, It's not.

[still tendon]

This problem was solved.

[thin prism]

Can somebody help me figure out how the heck I'm supposed to color a tile in a tilemap? There are so many things online for it but nothing is working.
Here's what I'm currently working with:

                Color color;
                // Logic to select a color - will always have a non-white color
                
                Tilemap.SetTileFlags(pos, TileFlags.None);
                Tilemap.SetColor(pos, color);
                Tilemap.RefreshTile(pos);
                // After all this, all tiles are still white (the sprites color)

[velvet moon]

hey guys
I am having trouble in unity 2D with Post processing
I followed a postprocessing tutorial but it wouldn't work
i am using the Light (URP)

[sweet nest]

Is there a way to only get touches that dosen't touch a canvas element?

[woeful sentinel]

You can use RectTransformUtility for that then check for mouse position

[sweet nest]

i dont want to use mouse position im making a mobile game

[woeful sentinel]

its the same as input position

meaning your touch input

[sweet nest]

i just want to know how to make something like this

if (Input.GetTouch(0) is not touching a Ui element)
{

}

i found a solution:

[worldly reef]

What's a good practice to get Cinemachine to always keep some object in frame (the player for example) but example to a limit to keep some other object in frame? I correctly have it setup to follow a target group of the player and the square and look at player, but that doesn't do what I want.

https://gyazo.com/527c89c66e5f54732390d600889ce477

Do I need to write some code that adjusts the camera if the square gets too far away or that available already in cinemachine?

[snow willow]

What you have is fine it's just that your maximum ortho size is not big enough when those objects get too far apart from each other

you can also play with the weights of thje items in the target group, and maybe create a script that will remove an object from the target group if it goes too far away from the player

[worldly reef]

Oh thanks, that's helpful.

[worldly reef]

Found a solution I'm pretty happy with. I setup two virtual cameras. One focuses on the target group and one focuses on the player. When the square gets too far away I transition to the player one. When the square gets closer, I move it back to target group.

[snow willow]

cool

[worldly reef]

Thanks for the help. Wouldn't have gotten there without you!

[fickle kiln]

hi, basic question, but how do I initialise prefabs at runtime? So I have 9 'number tiles' as prefabs and I want to have 7 of them chosen at random displayed at the beginning of a scene on a canvas in certain positions. I think I should probably use a list as they are mutable

I found this which just initialises a prefab and you attach it to a game object. If I have 7 prefabs to initialise, do I need 7 game objects, each with this script?

using UnityEngine;
public class InstantiationExample : MonoBehaviour 
{
    // Reference to the Prefab. Drag a Prefab into this field in the Inspector.
    public GameObject myPrefab;

    // This script will simply instantiate the Prefab when the game starts.
    void Start()
    {
        // Instantiate at position (0, 0, 0) and zero rotation.
        Instantiate(myPrefab, new Vector3(0, 0, 0), Quaternion.identity);
    }
}```

[snow willow]

You could put the prefabs in an array and instantiate each element of the array with a loop

so instead of public GameObject myPrefab you would use public GameObject[] prefabsArray;

then look up how to do a for loop over an array

[fickle kiln]

ok, how about how to choose 7 random prefabs to add to the array from the 9 I have available?

[snow willow]

shuffle the array of 9 and pick the first 7 from the shuffled array

https://www.dotnetperls.com/fisher-yates-shuffle

[woeful sentinel]

You can use Random.Range for this...

e.g: prefabsArray[Random.Range(0, prefabsArray.Length)];

It would get random index number in your array

[snow willow]

yes you can do that but if you want to pick 7 out of the 9 that code will lead to duplicates if called repeatedly

which is why I suggested the shuffle method

[woeful sentinel]

Or just add them to a List and eliminate each index number of the successful instantiated object

[snow willow]

that's much slower though

but for 9 elements it's not going to matter either way

[woeful sentinel]

man... 9... just 9 🤦

[fickle kiln]

for context, I'm trying to adapt a real life puzzle board game to unity...this is the 'pool' of number tiles the player can pick from...this was taken from an older python file so excuse the syntax - it's just 5 number 1 tiles, 7 number 2 tiles etc

numberTiles = {1:5, 2:7, 3:8, 4:8, 5:8, 6:7, 7:7, 8:7, 9:6 10:4, 11:3, 12:4,}

so yeh the player can have duplicates as long as there's enough in the pool of available tiles

[snow willow]

I mean think about how you would literally do this in a real life board or card game

you would shuffle the pile or the deck

and then take the top 7 items

I suggest doing the same thing in your code

[vast plume]

Hi, there are some bugs in my 2D game i cant really explain it
can i talk to someone in a call to show it?

[turbid heart]

Do your best to describe it. With a video if you must. Knowing how to describe your issue is essential for learning to debug

[turbid heart]

One way to start is to describe what you’re trying to achieve, and what is happening instead

[fickle kiln]

I have a problem that I asked last week but never got resolved...I have an orthographic camera that when I change it's size in the editor, doesn't actually change size in game

[orchid nest]

So I came here yesterday with my unity 2d isometric snapping system

but I am still having trouble

[turbid heart]

I remember this issue. You might want to try #💻┃unity-talk

[vast plume]

So my issue is that i have a 2d platformer game with moving and non movingplatforms and coins that do nothing jet you just can colekt them
when i go on the moving platform and go back to the ground after a while the player starts changing his size

[snow willow]

I think I know exactly what's wrong

Two things are happening:

• Your player is being set as a child of the moving platform when your player jumps on the platform
• Your platform has non-uniform scaling.

[vast plume]

Thats the issue

[snow willow]

so since your player is a child of the platform which has non uniform scaling, the player gets warped

you should rearrange the hierarchy of the platform so that it has uniform scaling (1, 1, 1)

the actual rectangle bit should be a child object of the platform parent object. That child object can have the scaling as necessary

then when your player lands on the platform, you just make it a child of the main platform parent object

Then you won't have to worry about rescaling the player or anything

[vast plume]

ok thanks

It worked don't had the problem again jet thanks

could you say me how i can make it so that the player can't rotate?

[turbid heart]

Like tilt itself when it lands?

[vast plume]

yes kind da but thats normal because of gravati but i dont want the player rotating at all

[turbid heart]

If it’s a rigidbody, look at the constraints on the rigidbody component

[vast plume]

nice thx

[orchid nest]

Ok this is the last time im getting to ask before just going to reddit. I need help implementing a 2d isometric grid system, as it can now only move left/right and up/down correctly, but going sideways doesnt work as you would need to halve the value for both, and I dont know when to make the code find out you are going sideways, and thats what I need help with

also

how do I paste code

It just gets deleted

[turbid heart]

See #💻┃code-beginner pinned

[orchid nest]

ok thanks

var currentPos = transform.position;
        transform.position = new Vector3(Mathf.Round(currentPos.x / gridSize) * gridSize,
                                         Mathf.Round(currentPos.y / gridSize) * gridSize / 2);

This is my code

btw

[shut geyser]

How do I put the background in the background (I don't know how to explain it)

[fickle kiln]

hi again, I'm using this script to try and instantiate my prefabs on the canvas but although they are being created, I can't actually see them on the screen (see screenshot)

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

public class StartupScript : MonoBehaviour
{
    public List <RectTransform> prefabList = new List<RectTransform>();
    private int n;
    private System.Tuple<float, float> startPositions = new System.Tuple<float, float>(-567, -538.4f);


    void Start()
    {
        int offset = 0;
        for(int i = 0; i < 7; i++)
        {
            n = Random.Range(1, 8);
            Instantiate(prefabList[n], new Vector3(startPositions.Item1 + offset, 0, 0), Quaternion.identity);
            offset += 100; 
        }

    }

    // Update is called once per frame
    void Update()
    {
        
    }
}```

[snow willow]

a few things:

• Your objects are not visible probably because they are simply behind your UI background image. Basically your UI is blocking everything. ALso if your objects are ui elements then you need to be instantiating them under the canvas.
• Why are you using a System.Tuple<float, float> instead of just Vector2?
• Your Random.Range call is starting at 1 (it should start at 0) and using hardcoded values. You should do it like this Random.Range(0, prefabList.Length). This will always give you a valid index into the array, and won't skip the first element like with 1 as the starting number.
• Your console window is not even visible in your screenshot so if you're getting any errors you won't see them

[fickle kiln]

changed it to this

    void Start()
    {
        int offset = 0;
        for(int i = 0; i < 7; i++)
        {
            n = Random.Range(1, 8);
            var newObj = Instantiate(prefabList[n], new Vector3(startPositions.Item1 + offset, 0, 0), Quaternion.identity);
            newObj.transform.SetParent(GameObject.Find("Canvas").transform);

            offset += 100; 
        }

    }

but it's now weirdly zooming right in...

[dusty maple]

Hi, I have this issue with rotating an object based on where my mouse position is.

This is my code:

        mousePos = (Vector2)Camera.main.ScreenToWorldPoint(Input.mousePosition);
        currentPos = transform.position;
        aimDir = (mousePos - currentPos).normalized;

        if (equipped)
        {
            if (rb != null)
            {
                lineRender.SetPosition(0, ballSprite.position);
                Vector2 clampedEndPos = Vector2.MoveTowards(ballTarget.transform.GetChild(0).transform.position, mousePos, 3.5f);
                lineRender.SetPosition(1, clampedEndPos);
            }

            float angle = Mathf.Atan2(aimDir.y, aimDir.x) * Mathf.Rad2Deg - 90f;
            ballTarget.transform.eulerAngles = new Vector3(0,0,angle);
        }

Any ideas what's causing this?

[snow willow]

Is your LineRenderer using world space or local space

Also what is ballTarget.transform.Getchild(0)

Why not just the player's position for that

[dusty maple]

World Space, and the ballTarget.transform.GetChild(0) is this:

ballTarget is here:

[snow willow]

Would really expect to use the player's position for that instead

Or ballTarget position

And the LineRenderer? World or Local?

[dusty maple]

I just tried it with the player's position, and it still has that offset (can't see it on this image, but the red mark is where the mouse actually was)

[dusty maple]

Line Renderer is set to World

BTW I'm using a Cinemachine Virtual camera if that makes a difference

[snow willow]

It does not, unless you have other "real" cameras besides the MainCamera

[dusty maple]

Nope

I tested with a Draw Gizmo to see where the system was registering the mouse position to be, and it seems to be consistent with where the end of the line renderer is, and it's lined up properly with the rotation of the aiming reticle. So what I ended up doing was making the mouse invisible on startup and then just having another gameobject with a sprite renderer be where the system is registering the mouse position to be.

It's lining up properly now

[white cedar]

I have this two scripts, the left one is the to the camera follow the player, and the right one it's to sweep between the camera follow the player or not. But is not working D:

[sharp lichen]

You can simplify the left one

if (collision.CompareTag(“Player”))
{
   cameraFollowPlayer = !cameraFollowPlayer;
}```

It’s also not working because the left one doesn’t tell the camera anything, it just updates its own bool

[white cedar]

thank you, thank you

[deep urchin]

Hello. I'm trying to get a script to rotate a object by a certain amount when I click space. I tried 2 scripts but neither one works, here are the scripts:if (Input.GetKeyDown(KeyCode.Space)) { transform.rotation = Quaternion.Euler(0, 0, 5); }andif (Input.GetKeyDown(KeyCode.Space)) { transform.rotation = Quaternion.Euler(0, 0, transform.rotation.z + 5); }What is the correct way to rotate it?

[late viper]

try using Transform.Rotate() https://docs.unity3d.com/ScriptReference/Transform.Rotate.html

[deep urchin]

Ok thank you, it works now

[storm coral]

can someone help me turn my chunk generation infinite, so it just expands then the player can see further?

[storm coral]

nevermind

[marsh oar]

hello, im following a brackeys tutourial, the play game one, when i drag in the script to the button, for the function, it only says monoscript, this is happening with every script that im dragging in.

here is my script

[turbid heart]

did you attach the script to the button?

[marsh oar]

yes

[turbid heart]

can you show us the inspector so we can see what you mean by it only says monoscript?

[turbid heart]

and can you show where the script is attached to the button?

[marsh oar]

here

[turbid heart]

do you have any errors in your console that might be stopping your code from compiling?

[marsh oar]

no, i don't have any errors in my console

[turbid heart]

let me open up Unity and test on my side 🙂

[marsh oar]

k, thx

[hollow crown]

https://help.vertx.xyz/?page=Interface/Unity Events/Incorrect Assignment

[turbid heart]

so the issue is usually people drag the script itself into the field instead of the object with the script?

[hollow crown]

Yes

[turbid heart]

will keep that in mind, thanks vertx!(I hope that's your cat, it's so cute)

[marsh oar]

thank you so much, it works now!!

[bronze anvil]

'm making a runtime level editor with isometric tilemap support.

The level editor has layers that can be added, duplicated, deleted, and reordered.
As I'm using Isometric Z As Y, every time the layer is reordered, I need to remove tiles and set tiles for all affected layers. This usually results in hundreds of actions.

If I had two tilemaps instead, I would just have to switch their positions.
But for every tilemap, I also have additional tilemaps for preview, grid, etc. so this means there would be actually 5 tilemaps per layer. The user can create any number of layers he wants, but this could be limited if needed.

What's your opinion about this issue? If I use a tilemap per layer instead of 1 big tilemap with z-axis, are there any other issues related to the draw order or performance?

[potent phoenix]

how do i make a countdown that only loads the first time a scene is loaded, before doing the updates

[turbid heart]

Start a coroutine in start? Or do a good old timer based countdown in Update that starts with a bool set in Start

[upper rune]

Is there a way I can use the camera width as a maxX to say an object shouldnt be able to move outside of maxX?

[turbid heart]

Look into ViewportToWorldPoint. Or vice versa

[upper rune]

thanks!

It seems that either I can't see the full camera view or the values are slightly off

[turbid heart]

dont forget to account for half of your object's width, if the pivot's at its center. and that viewport is from values of 0 to 1

[upper rune]

ohh okay, I think thats actually what the problem is

[potent phoenix]

what does this mean?

using UnityEngine;
using System.Collections;
using UnityEngine.UI; //Need this for calling UI scripts
using UnityEngine.SceneManagement;

public class Manager : MonoBehaviour {

[SerializeField]
Transform UIPanel; //Will assign our panel to this variable so we can enable/disable it
Transform deadPanel;
bool isPaused; //Used to determine paused state
public Eel eel;
void Start ()
{
    UIPanel.gameObject.SetActive(false); //make sure our pause menu is disabled when scene starts
    isPaused = false; //make sure isPaused is always false when our scene opens
}

void Update ()
{
    //If player presses escape and game is not paused. Pause game. If game is paused and player presses escape, unpause.
    if(Input.GetKeyDown(KeyCode.Escape) && !isPaused)
        Pause();
    else if(Input.GetKeyDown(KeyCode.Escape) && isPaused)
        UnPause();

    bool isDead = eel.isDead;
}

public void Pause()
{
    isPaused = true;
    UIPanel.gameObject.SetActive(true); //turn on the pause menu
    Time.timeScale = 0f; //pause the game
}

public void UnPause()
{
    isPaused = false;
    UIPanel.gameObject.SetActive(false); //turn off pause menu
    Time.timeScale = 1f; //resume game
}

public void QuitGame()
{
    Application.Quit();
}

public void Restart()
{
SceneManager.LoadScene(0);
}
}

with this code

[wide ginkgo]

It means you didn't assign something to UIPanel on your GameObject that has the script attached.

Will assign our panel to this variable so we can enable/disable it

[abstract olive]

It tells you that on line 13 you're referencing something that is null.

[turbid heart]

double click the error, it'll take you to the line with the error. it means you're using something that's null

[potent phoenix]

that line is just the void Start()

[potent phoenix]

everything is already in

[turbid heart]

really? it takes you to Start when you double click the error?

[abstract olive]

Show your inspector where you've assigned UIPanel.

[potent phoenix]

yep

line 13 is the Start

[abstract olive]

Then you probably have another one in your scene.

Type t: Manager in the search bar at the top of the hierarchy panel.

[potent phoenix]

_GM is the name of the object that has the Manager script

[abstract olive]

Do you have any other console errors?

[potent phoenix]

nop

[abstract olive]

Can you search while the game is running?

[uneven rune]

Hi, just saw Pause and Unpause, and it looks like you could simplify that.

void Update ()
{
    //If player presses escape and game is not paused. Pause game. If game is paused and player presses escape, unpause.
    if(Input.GetKeyDown(KeyCode.Escape))
    {
        isPaused = !isPaused; // inverts the isPaused bool
        UIPanel.gameObject.SetActive(isPaused); // sets the UIPannel to be active if it is paused, or not if it't not
        Time.timeScale = someBool ? 1 : 0; // Sets the timescale to 1 is someBool is true, or 0 if it is not
    }
    bool isDead = eel.isDead;
}```

[potent phoenix]

same thing

[potent phoenix]

yeah i had a feeling, thanks!

[uneven rune]

No problem.

Also, the original script sometimes checks if the button is pressed twice, so when doing things like that you should check if the button is down, and then inside that do if() and else. The script I gave doesn't have that minor issue tho.

[upper rune]

@turbid heart it seems to be still offset slightly

[potent phoenix]

yeah

[turbid heart]

yeah I can't tell you why unless you show me your code and your game screen?

I used this box collider x value / 2

https://gyazo.com/c5da5f3b0eb3e4a9868946ab837b8d5a

    private float maxX;
    private float minX;
    public float speed = 2/1000f;
    // Start is called before the first frame update
    void Start()    
    {
        Vector2 bottomCorner = Camera.main.ViewportToWorldPoint(new Vector3(0, 0, 0));
        Vector2 topCorner = Camera.main.ViewportToWorldPoint(new Vector3(1, 1, 0));

        

        maxX = (float)(topCorner.x - 5.514648 / 2);
        minX = (float)(bottomCorner.x + 5.514648 / 2);
        Debug.Log(maxX);
        Debug.Log(minX);
    }

    // Update is called once per frame
    void Update()
    {
        var enemyX = transform.position.x + speed;

        transform.position = new Vector2(enemyX, transform.position.y);

        if (transform.position.x > maxX)
        {
            moveDown();

        }
        else if (transform.position.x < minX)
        {
            moveDown();
        }
    }

[uneven rune]

If you use reply, rather than pinging them, it will make it easier to follow the conversation, and I can more easily help and figure out what is going on.

[turbid heart]

so your issue is it slightly exits the screen before bouncing back?

[upper rune]

oh yeah good tip

[upper rune]

yeah exactly

[turbid heart]

why do you hardcode your value? and you're using your collider's size, which you can see if larger than your actual sprite

[upper rune]

just hardcoded it as a test

[upper rune]

it is larger but its larger by such a small amount that it wouldnt really matter

im very zoomed in, on that first picture

[potent phoenix]

wait a second

how did htat work lmao

[turbid heart]

could be because you use > instead of >=

[potent phoenix]

pizza your code fixed that error

[upper rune]

Okay I tried it, seems to look the same

[turbid heart]

look at the answer in this thread to see how to get the actual size of your sprite
https://answers.unity.com/questions/1489211/getting-sprite-heightwidth-in-local-space.html

[upper rune]

oh nice

uh

I have no renderer on the prefab

the sprite is composed of many cubes

thats why I thought box collider bounds would work best

I think I know the issue

if (transform.position.x >= maxX)
        {
            moveDown();

        }

this is checking if the x position of the entire row of enemies has hit maxX

which is the center of the row

now I fixed it

[turbid heart]

great!

[upper rune]

thanks for the help!

[potent phoenix]

it doesn't even tell me what the error is anymore

atleast, where the error is

[snow willow]

this looks like a bug in Unity itself

[potent phoenix]

fun

[upper rune]

wait I thought it fixed it

but it didnt

it only works if I have 6 enemies in the row, if I have less than that its offset again

[upper rune]

if (transform.position.x + (transform.position.x / 2) >= GameManager.screenMaxX)

I thought this would solve it

cause this made sense in my head ^

but its apparently wrong somehow

[turbid heart]

it's transform.position.x + (half the width of your grid)

[upper rune]

hmm that doesnt seem to work either

https://gyazo.com/7f5b4d993e2c693e9074c1f8be4cdeea

unless you meant grid as in the grid of enemies

in which case would be the transform.position.x/2

[turbid heart]

no, transform.position.x /2 is half your position,

i'm talking half your grid of enemies

so 3 of your enemies + half of the center gap

[upper rune]

riight

do I have to use bounds for that again?

cause the row is just an empty object with a bunch of enemies as children

[turbid heart]

then use the prefab or something use the bounds of it to get the width

[upper rune]

i have no idea how to get the bounds of the group

it seems very complicated

[faint sparrow]

If you want all your object positioning relative ti center, You need to get total width required / 2 so that is fartest position, and you also need relative position of each object and i think substract it, not to remember you also need an offset for it

[upper rune]

Yeah I managed to figure out how to get the total width / 2 now but I think it doesnt recalculate the center

Its weirdd

[faint sparrow]

That where is relative pos take place

[upper rune]

Right

[faint sparrow]

Wait i think i stored on my phone

[upper rune]

Would be super useful!

otherwise I have a bounds.center to work with

cause when I tried drawing a gizmo to debug, the gizmo worked perfect because I could use bounds.center + bounds.size

[faint sparrow]

Couldnt find it sorry...im scroll up 5mnt with and cant find it

But i think i missed what you want, if you need fartest screen you can go, simply screenwidth / 2 will give you that

[upper rune]

yeah that works until one enemy dies

this is when using this : ```csharp
if (transform.position.x + enemyRowWidth/2>= GameManager.screenMaxX)

[faint sparrow]

Isnt that because you didnt update enemyrowwidth after some dies?

[upper rune]

right now its updating every frame

[faint sparrow]

What updating evrry frame?

[upper rune]

enemyrowwidth

[faint sparrow]

You dont need that, only if any dies you update the value

[upper rune]

yeah true, about to change it rn

[honest python]

how do I get the collision to be more precise

[rocky temple]

polygon collider I would assume

instead of box

[honest python]

nono

I meant

there's a small gap between the top 2 colliders

[rocky temple]

oh

[honest python]

but it still doesn't see it as if it exited eachother

[turbid heart]

Why not just shrink the collider

[honest python]

what?

cuz I don't want to

if u look at the collision boxes

the green ones

there is a small gap between them

that is what I want gone

so that they're all equally spaced

[signal crystal]

Im sorry Im new in this discord, which room do i have to post if i have a question about unity?

[honest python]

depends on what in unity it's related to

[turbid heart]

So then reposition them according to their height

[turbid heart]

Just ask in a channel most relevant to your question

[signal crystal]

I have a problem when I want to build and run

[turbid heart]

Then maybe #💻┃unity-talk

[honest python]

what do u mean?

[turbid heart]

Get their height using SpriteRenderer.bounds and use that as the offset between them

[honest python]

well I can't

it just doesn';t rlly work for my project

[wooden ruin]

Is there a way to easily disable and re-enable an object from a script on it?

or just making it invisible works too

[rocky temple]

gameObject.SetActive(false);

and then gameObject.SetActive(true); to reenable

[wooden ruin]

I have that, but it disables the script too

[rocky temple]

yes it disables the entire object

[wooden ruin]

So how do I have that not happen

If the script is disabled, it can't re-enable itself

[rocky temple]

public Color invisible; then in the inspector set this colour's alpha to 0

gameObject.GetComponent<SpriteRenderer>().color = invisible;

[wooden ruin]

Ok, I'll try that

[rocky temple]

and to reenable just make another public color and set it to max alpha
