i know why i couldnt jump

#

i mean sometimes i was jumping higher and lower

#

it was only happening when i was standing still

teal viper
#

I really think the concept of counter movement is not great

tender stag
#

yeah that was just quickly scrapped so the player would slow quicker

#

im gonna do it properly later

#

for now i increased friction

teal viper
tender stag
#

i did this for now

#

works alright

#

i mean it works and feels smooth

I have a script I made in an attempt to try to move the eyes of a character move according to a bone.
The script detects for a white vertex color (the eyes) so it finds the UV of those, when I use this script what happens in the first image happens. It only goes to the color where the UV would be at a very small scale, so it's like a base color. The second image is what it should appear like.

Uh, duh, thanks LOL, totally didnt think about that

quaint crystal
#

is EventSystem a good place to put your scripts? whats the common gameobject to use?

#

scripts that will always be used i should say

shell sorrel
#

normally would just make a new GO for them

#

with a appropriate name for whats on it

I want to keep object in front of player (first person game).

transforming with this code:
//Statistics.MovedObject.transform.position = CameraTransform.transform.position + CameraTransform.transform.forward * distance;
isnt doing it smoothly (but fully working)

someone said, if i use rigidbody i should use rb.MovePosition. So ok, i tried some ways but cant figure out how should it looks.
Actual code:


    public float distance = 2;
    public Rigidbody rb;

    public float m_Speed = 5f;


rb = Statistics.MovedObject.GetComponent<Rigidbody>();

rb.MovePosition(CameraTransform.transform.position * Time.deltaTime * m_Speed);
rb.MovePosition(CameraTransform.transform.forward * distance * Time.deltaTime * m_Speed);```

And object is destroying (i think object is  "crashing") or isnt moving how should (somewhere far).
frigid sequoia
#

I think you don't really need to move anything with code just, some parenting

gleaming nymph
#

So only

            Statistics.MovedObject.transform.parent = Player.transform;
            Statistics.IsMovingObject = true;
            rb.isKinematic = true;
            rb.detectCollisions = false;```
Will works?
frigid sequoia
#

To place something in front of the camera, just parent it to an empty object with the offset you want which is parented to the camera

gleaming nymph
#

Can i parent it to player?

frigid sequoia
frigid sequoia
gleaming nymph
#

bcs its water bottle lol

frigid sequoia
#

Probrally can do that

gleaming nymph
#

no its not working'

#

its moving too slow

frigid sequoia
#

If it is parented to the player it is for sure moving at the same speed as the player

gleaming nymph
#

i send u code and im telling you its not moving at the same speed as the playerr

#

its really slow i think bcs of rigidbody

frigid sequoia
fathom mist
#

So I have a pickup that is only supposed to be allowed to be interacted with once a tracker hits 4 which then triggers a scene change but the interaction isn't working and I'm not sure what I'm doing wrong? I can send screenshots of the code in a moment

frigid sequoia
#

But it depends of what you are actually doing

gleaming nymph
#

lmao

fathom mist
#

This scipt is assigned to the player character

gleaming nymph
#

bottle is now parented to player, and was attached in cursor position. I moved some and its not on cursor

sly wasp
frigid sequoia
# fathom mist

Start by adding a Debug.Log to make sure the stuff is being called

gleaming nymph
#

bro its moving but very slow so its parented

frigid sequoia
#

If you do want to have physics still, just increase the force been applied lol

barren wing
#

personas

#

question

gleaming nymph
fathom mist
#

like this? I forgot how to properly add a debug log aaa

image.png
#

If it is then it isnt calling it

barren wing
#

if i want to ignore a function in a inheritance, do i use Virtual and Override in the inherited file?

gleaming nymph
barren wing
#

ill pass photos xd

#

i want to ignore this function, what do i do?

image.png
gleaming nymph
#

and unity wiki and someone said if i want rigidbody i should use MovePosition

frigid sequoia
gleaming nymph
#

i just parented object to player

#

Statistics.MovedObject.transform.parent = Player.transform;

#

maybe i should parent it to camera?

#

but it will not work too

frigid sequoia
gleaming nymph
#

when i will move player it will move (even slow) but when i will stand, water will be not moving if its not parented to camera

#

i think

fathom mist
#

I'm not getting any errors which is the strange thing

gleaming nymph
#

bad idea daleo with parenting

#

i think i should use MovePosition or transform but i want to transform it smoothly, with transform its tremble

fathom mist
#

Yeah it's giving me nothin

teal viper
frigid sequoia
# gleaming nymph i just parented object to player

I though you wanted somethig to stay in front of the player like a gun or something like that, if you want a drag and drop feature, yeah, just get the point at which the cursor is pointing and apply force to the object towards that direction every frame

#

Just mess with the values

barren wing
#

im using the same script for an enemy that has health, but also a shield

#

i cant change the first script, because every enemy will now have a shield

frigid sequoia
barren wing
#

so, i want to redo the function, but in another script

#

using inheritance

frigid sequoia
gleaming nymph
teal viper
barren wing
#

like this?

#

this ios the other class xd

#

i only copy pasted

gleaming nymph
#

no

#

i tried update and fixedupdate

teal viper
fathom mist
#

which im not sure why? Is the tracker getting deleted?

image.png image.png
barren wing
#

oka, ill try

#

muchas gracias

frigid sequoia
gleaming nymph
#

i can use transform now

#

everything working

#

lol thanks

fathom mist
#

can I get the tracker to carry through into this scene?

frigid sequoia
frigid sequoia
fathom mist
#

No not really

#

Because I dont want the actual objects to remain in this scene

#

I want the tracker to stay the same

frigid sequoia
fathom mist
#

But the pickups need to dissapear ;^;

frigid sequoia
#

Then how the hell are you counting up to 4 if the counter is on the pcikup that you are destroying? XD

#

Doesn't the player or some other game manager component that is permanent store that data?

barren wing
#

another question @teal viper, sorry 2 annoy you xd

since the script im trying to do inherits from the script "Enemigos", if i use this line to send a number, it will work?, o i have to change the name of the getcomponent to the new script?

detections[i].collider.GetComponent<Enemigos>().RestarVida(3);

eternal needle
fathom mist
#

like i pickup stuff outside in the previous scene and then move inside to pickup the mask but I dont want the sprites of the pickups to remain loaded in and made visible on this scene if they werent grabbed by the player qwq

summer stump
frigid sequoia
fathom mist
frigid sequoia

#

yeah

frigid sequoia

Like the same object, not another prefab of the player

it should?

# fathom mist it should?

If you want the score to remain between scenes the player object should not be destroyed on load and should keep the score count if that's the case

fathom mist
#

I dont 100% understand the scripting behind it

#

this is my player controller if it helps

"move the eyes of a character move according to a bone" doesnt really make sense

ty dawsi for inspiring me to try it and see

#

that's what the professor had us do

frigid sequoia

Why is not just an int on the player script?

so ,, idk

the uv of the eyes must track the bone

Ah, I think EpikFishy meant to respond to Bawsi (right above that comment Regular)

this is the soundd controller script

#

The code that detects for white on the mesh works, and it knows where to target the UV at, the only problem I am having is tracking it

#

Converting the bone's position to UV x and y

fathom mist

#

yeah idk I just want the cutscene to play so i can be done witht this assignment im so tired and i still have a midterm to do

barren wing
eternal needle
barren wing
#

i already tested it, ty anyway uwu

teal viper
sly wasp
teal viper
#

And the issue is still the same as what I mentioned yesterday: bone position doesn't map to uv positions one to one. You'll need some kind of remapping function for it to work as you intentend.

frigid sequoia
#

Should be enough to keep the score

fathom mist
#

alright

#

isnt that what this is?

image.png
teal viper
eternal needle
#

all of this could just be done with transform.LookAt(whatever); (or by setting the rotation directly)

sly wasp
sly wasp
teal viper
#

No, that's for the whole eye object. You don't need a bone if you do it correctly.

#

And don't need to mess with uvs.

sly wasp
#

The eyes are attached to the head and are not fully modeled

#

I need to move the UVs so the eyes look around

teal viper
#

That's exactly the problem that you should be focusing on: making the eyes into a separate model.

timber tide
#

most 2D eye stuff ive seen usually has multiple different frames

#

dynamically animating them seems like a pain but I guess you can offset the texture uvs

teal viper
#

That's what they're trying to do. The problem is that they just map bone local position to uvs directly. Obviously that's not gonna work.
Not to mention, that it's probably gonna be slow - modifying the whole character l mesh data every frame just to move the eyes.

timber tide
#

vr chat peeps probably got some ideas

sly wasp
sly wasp
#

And without separating them

rocky canyon
#

shader

#

do u just need the eyes to follow something?

timber tide
#

if they're using transform values I wouldnt use shader

sly wasp
rocky canyon
#

why not cut the eyes out, add two spheres and actually rotate em (like ur own eyeballs)

sly wasp
#

I just said I'd like not to

rocky canyon
#

instead of doing all this UV stuff

#

its gonna be super difficult

sly wasp
#

I'm ok with that

timber tide
#

that's basically what dilch was suggesting

rocky canyon
#

alrighty then.. keep trying. unfortunately i can't help out with that

teal viper
sly wasp
#

Okay, suppose I do that, how would I make it follow the eye bone?

shell sorrel
#

so whats the issue, like wanting to adjust the uv's to nudge towards a certain direction

teal viper
sly wasp
#

Yes

#

How do I make the shader follow the eye bone

shell sorrel
#

would have to feed its position back into the shader as a vector

#

then do the math in there

teal viper
#

You'll calculate the uv offset in C# and pass it into the shader.

#

Or calculate in the shader I guess.

shell sorrel
#

yeah i would pass it as a directinal vector

teal viper
#

I think calculating on the C# side would be better, as you probably would need to have most of the logic in the fragment shader.

shell sorrel
#

well uvs i would do in the vertex shader anyways

teal viper
#

They only need to adjust the uvs for the eyes part though. The wouldn't be able to do that in the vertex shader

shell sorrel
#

but yeah would create a vector in C# first, for the look at direction, and use it to offset uvs in the vertex shader

teal viper
#

My suggestion was a mask for the eyes, sample it in the fragment shader and runt the adjustment logic there.

sly wasp
#

Is there a way to make an instance copy of the material just for the eyes in the script, and then adjust the material offset?

whole idol
#

why does my vsc have no autocomplete?

shell sorrel
#

can mask them via vertex color

#

A mask sounds good

#

You can mask parts based on the vertex color?

queen adder
#

I can’t find the fly in GoGoLoco Beyond by Frandera 1.8.3

shell sorrel
teal viper
shell sorrel
#

its just a matter of having the data on the verts

teal viper
#

But it would be simpler indeed if eyes were a submesh.

shell sorrel
#

but yeah like jut make the eyes be a submesh with its own material slot

sly wasp
#

A submesh?

#

I am unsure of what that is

shell sorrel
#

what you want is one of those things that has no indvidual hard part to it. but does mean you need to understand a little about alot

#

on both the dcc and engine side of things

timber tide
#

usually people use shrinkwrap for 2D eyes in blender

#

easier to change the UVs when it's just a quad

rocky canyon
sly wasp
#

Ohh

rocky canyon
#

multiple pieces

sly wasp
#

Ik what you mean

shell sorrel
#

yeah i was kinda assuming the eyes where like a quad sphere

#

with a good projection

sly wasp
#

but that means the eyes would be a separate object..

rocky canyon
#

i also think thats the better approach

#

to alteast seperate the eyes

timber tide
#

who cares if it's a seperate object

sly wasp
#

Me

shell sorrel
#

also why would you care if eyes are a seperate object

timber tide
#

just reference it

rocky canyon
#

why?

teal viper
#

Submesh is when a part of the mesh is using a different material. You need to define that part in your modeling software.

rocky canyon
#

do u have any logical reason to have it all one piece?

shell sorrel
#

its very common for a character to be multiple transforms and meshes

sly wasp
#

Ohhh

rocky canyon
#

Oooo

sly wasp
#

I think I understand

#

Yes

#

Yes

teal viper
#

That wouldn't fix your issue if you keep on using the current code though

#

The issue is fundamentally you not mapping position to uvs correctly.

sly wasp
#

So in blender (my software I use) I will assign a material called eyes and I will put the same texture on it and in the script I will reference the material to move the offset of the UV based on the bone's position?

#

The eyes will have the eyes material of course

timber tide
#

dont need to assign it in blender, but you need to separate the model in it for the eyes

sly wasp
#

I am fine having another material ig

sly wasp
#

This material method seems to be a great approach

teal viper
#

As it's gonna make a separate draw call.

shell sorrel
#

yeah but would not worry about draw calls at this point

sly wasp
#

Thanks for the idea

shell sorrel
#

its common for a character to need a few for features like this

teal viper
#

I just assumed they do it this way mainly for performance reasons. Which is a misunderstanding

sly wasp
#

I see that modifying the UV on a mesh every frame may not be so good 😅

shell sorrel
#

like if its a rts character yeah i want that ultra cheap

#

but like a first or 3rd person rpg character can afford more on it

teal viper
#

The point is, why do it harder if you can make it simpler. And more performant.

summer stump
#

iirc, this is an endless runner
Unless it's a different project now

shell sorrel
#

but yeah eyes are rigid anyways

#

so i also see no reason not to just have them rotate, could even do it via a ik target

#

or simply do it in engine wiht logic

timber tide
#

Im not a fan of doing materials in blender as I run into more problems with that

sly wasp
#

I am just big on the little details like eyes moving and facial expressions etc

rocky canyon
#

is that wht ur talkin about

shell sorrel
#

yeah its just about getting slots on the right faces

rocky canyon
#

^ 👍

#

gosh, i wish i could move blender materials over to unity 🤤

#

i have sooo many procedural materials that are awesome

timber tide
#

beyond being stuck to basic specular shaders and such, you can't really edit the matieral further once it's in unity

sly wasp
shell sorrel
rocky canyon
#

youd think they'd have a plugin by now that converted blender materials over to shadergraph

shell sorrel

was really nice

You can only move just materiasls tho

and can u tell me why its rotating in only one axis?
I want to rotate it in face of player (its parented to player)

wintry quarry
#

"rotate it in face of player" is very vague

gleaming nymph
#

i will show u wait

shell sorrel
#

rotate to face player would just get a directianl vector and make a look rotation from it

gleaming nymph
#

player is holding water bottle

playerwater.PNG
#

and i want to rotate it with scroll

wintry quarry
#

well it depends on what its local rotation starts as

#

If you want to rotate around some specific axis the easiest thing might be to use world space rotation and use Quaternion.AngleAxis to generate the relative rotation

rocky canyon
# 
        float scrollDelta = Input.mouseScrollDelta.y;

        if (scrollDelta != 0)
        {
            // Rotate the object based on the scroll wheel input using local rotation
            transform.localRotation *= Quaternion.Euler(Vector3.up * (rotationSpeed * scrollDelta));
        }```
#

this is how id do it.. i have a similar mechanic

lusty flax
#

I've been trying to make a program that makes a 2D platformer character squash and stretch based on its velocity, but have had no luck. Can someone help?
This is my current code:

float xSize = 1 + Mathf.Abs(rb.velocity.x * 0.05f);
float ySize = 1 + Mathf.Abs(rb.velocity.y * 0.05f);
if (xSize > ySize)
{
    ySize = 1 / xSize;
}
xSize = 1 / ySize;
spriteParent.transform.localScale = new Vector2(xSize, ySize);

spriteParent refers to the GameObject which holds the sprite for the character.

rocky canyon
lusty flax
rocky canyon
#

does it have to be fine tuned?

#

i feel animation could work if its just jump / ground

wintry quarry
#

what's going wrong here

rocky canyon
#

shit wont work 😅

lusty flax
lusty flax
rocky canyon
#

u can use a blend tree in the animator...

#

could blend between full squish/ moderate squish

shell sorrel
#

i would be tempted to use blend trees as well

rocky canyon
#

pass in the y velocity of the rigidbody for example

shell sorrel
#

since you dont want to do it per direction on velocity since it will look wrong not maintaining volume

#

like if you strech vertically you always want to squash horzontally for example

lusty flax
gleaming nymph
gleaming nymph
wintry quarry
lusty flax
#

does this channel have embed perms (i want to upload the video of what's gone wrong as an embed link)

#

it's that when it shifts between squashing and stretching, it's too violent and instant

#

nevermind

#

also dont mind the terrible animations which are not done

#

it shifts too instantly between squashing and stretching and looks unnatural

shell sorrel
#

so to make it not instant, you want to set a stretch target and move towards it over time

#

or like smoothDamp towards it

swift crag
#

for squash and stretch, maybe you want something like...

shell sorrel
#

so instead of applying it directly each update calculate the ratio you want, save it to a field then over time move towards those values

swift crag
#

I use something that's stolen adapted from the code shown in this video

shell sorrel
#

also yeah t3ssel8r knows there stuff, watch that video

swift crag
#

it's great for making wiggly motions

#

i use it to animate UI elements

#

unfortunately, fun, bouncy buttons are not tonally consistent with a horror game

#

but hey..buttons..

lusty flax
#

ok

#

thanks for all the help, guys!

swift crag
shell sorrel
#

the idea of having a target you move to over time you will hit alot

swift crag
#

if you need a Vector2 you can just copy-paste SecondOrderDyanmicsVector3

#

I had to do that because the version of C# that unity supports doesn't have numeric interfaces yet

#

so I can't just say "any type that you can add and multiply"

#

Serialize a SecondOrderDyanmicsFloat and set it up in the inspector, then call Update on it every frame (in your own Update function)

#

and call Setup on it before you use it

rocky canyon
swift crag
# 
        sizeDynamics.Update(Time.unscaledDeltaTime, sizeGoal);
        transform.localScale = sizeDynamics.Position * Vector3.one;
#

e.g.

lusty flax
swift crag
#

i need to go re-learn differential equations so that i fully understand the theory here, lol

#

(and implement the cool preview that the video has, so you can see what the impulse response looks like)

lusty flax
#

there is actually no way a smooth damp just fixed the entire problem

#

i refuse to believe

smooth damp is pretty cool (:

If you declared a class named PlayerMovement, then you can't refer to it as Player_Movement.

that is one of the issues yes.. bc ur script is player_movement

not sure I understand what you're saying, are you implying that perhaps the way my public class is defined is wrong ?

ur filename and class have to match

player_movement is not the same as Player_Movement

not to the compiler, but will to unity when referencing

It's confusing to suggest that the compile error is caused by the file name.

you'll need to keep two floats for the velocities

well, actually...

#

can you pass a struct field by reference?

I haven't actually thought about that

#

you can

swift crag

foo.x = Mathf.SmoothDamp(foo.x, target.x, ref vel.x, 1f);
#

that's what I'm thinking of

shell sorrel
#

though its on the lines i of needing to test to be confidient

slender nymph
#

just tested on dotnetfiddle and it does seem to work

swift crag
#

yep, the compiler is happy

shell sorrel
#

well knew the compiler would be happy

#

more about did it reference a coppied value

#

thus not writing back to the same one

swift crag
#

You wouldn't be able to.

#

A property doesn't give you an lvalue

#

an lvalue being a thing you can assign to, basically

Hello, I have a theoritical doubt- should I not use Navmesh agent with Colliders? When my Navmesh agent collides with a gameobject, it becomes jittery. Its position and rotation keeps on changing 0.0x values. Both gameobjects have colliders and rigibbody set.Should I handle this somehow or not use colliders here ?

swift crag

(unless x is a property, in which case you've run a function that returned a value)

# gleaming nymph ye but i want to scroll to player axis

I tried function transform.LookAt(Player)
And in editor i see, that when im moving camera bottle is every time in front of player,
X axis is changing when moving, Y axis is always -180 and Z axis is 0.

How it works then, i thougth that X axis is up and down, now left/right.
How can i face bottle to player and rotate with scroll? @rocky canyon

Whats up guys just found this discord on google and im about to lose my mind on my game if anyone can help

Possible silly question

Im using a material for something and trying to set the offset

I have face.material.SetTextureOffset

That works but how do I get the material for element 1?

dusky dirge
#

update: just had to update my Unity version LOL

shell sorrel
ivory bobcat
shell sorrel
#

or even better figure out which material it is and directly reference it

sly wasp
#

i just access the material directly

#

(materialName).SetTextureOffset

shell sorrel
#

keep in mind, you might want to instance the material first then assign it back

#

that way your changes to it only effect the one character

sly wasp
#

Ahh ok

#

How would I do that?

#

wait..

ivory bobcat
#

If you modify the material from a renderer reference, it would automatically create a new instance for that object.

shell sorrel
#

yeah that or via a constructor

ivory bobcat
#

Make sure to free the material though...

Returns the first instantiated Material assigned to the renderer.
Modifying material will change the material for this object only.
If the material is used by any other renderers, this will clone the shared material and start using it from now on.
Note:
This function automatically instantiates the materials and makes them unique to this renderer. It is your responsibility to destroy the materials when the game object is being destroyed. Resources.UnloadUnusedAssets also destroys the materials but it is usually only called when loading a new level.

you probably have a duplicate script

whole idol
#

these are all the scripts

image.png
slender nymph
#

oh my mistake. of course. then your error is resolved

#

but seriously, you have a duplicate class called player_movement (also bad name, c# uses PascalCase for types not snake_case)

#

use the search feature in your configured IDE to find the duplicate

ivory bobcat
#

Or did a bad move and the meta files are all screwed up

rocky canyon
whole idol
slender nymph
#

have you used the search feature in your IDE to find duplicates in the project?

ivory bobcat
#

Did you move the script recently?

whole idol

no

also I just noticed all my files are named with a .cs at the end. Not sure if they should be named as .c# or not but this looks sus

slender nymph

cs stands for c sharp

Or is the class defined else where - in another script

its not ( I just checked )

It's one of the above.

again, have you used the search feature in your code editor

but its a small block of code

you mean the ctrl+f thingy?

yes, obviously

you can use that to search the entire project

you do not need to keep posting this block of code

it does not prove anything

The block of code isn't the issue

slender nymph

You've either got a duplicate script, class in another script or the meta file was corrupted

I got nothing

slender nymph

i'm gonna go ahead and bet that the IDE isn't configured so it isn't showing them errors or including all of the files in the project which is why they are so adamant that there is no duplicate

Can someone help me, how can i rotate object up and down with scroll, but object will facing to player?
Statistics.MovedObject.transform.localRotation *= Quaternion.Euler(30, 0, 0);
Actually im using this ^ but its rotating only one way, not checking player angle

slender nymph
#

but its rotating only one way, not checking player angle
what do you mean by this

cosmic dagger
rocky canyon
#

i mentioned it earlier.. (unless u wanna do math and add subtract rotations and stuff) it'd be nice to have 1 container that faces the player.. and then spin the thing in a child container

#

point the root at the player.. rotate the child on a certain axis (locally)

gleaming nymph
whole idol
gleaming nymph
rocky canyon
#

the second one should only rotate on a local axis of ur choice..

#

the outer container would face towards ur player

rocky canyon
#

no matter where u rotate the Main parent.. the child would only rotate on its local axis like so

#

im having trouble myself with the Root looking at the camera.. gimbal lock stuff.. (weird rotations) its always trial and error for me when working with quaternions and rotations 😅

gleaming nymph
#

look

rocky canyon
gleaming nymph
#

fast paint

#

i need to face object everytime to player and unable it to spin left or right with scroll, only up and down

#

i have water always in center of screen, i need it to be always facing player, and when i scroll it will rotate up or down

water2.PNG
#

And it cant be in one axis, because in this case it can rotate left or right (will not be facing player)

rocky canyon
#

if its attached to the player.. i dont understand why it isnt always facing the player 🤔

slender nymph
#

seems like the problem is they are rotating the object around its own local X axis when in reality they want to rotate it around the X axis for the containing object (assuming they are using some parent object to keep it in relation to the player)

rocky canyon
#

ya, thats how im thinking about it.. but im confused tbh. when he said no earlier.. thats not what he wants.. and every time he explains it I think of hte same thing

#

maybe a video of what he has.. and then some context w/ that may be helpful

#

no offense but ur drawing did me no good 😅

gleaming nymph
#

When i turn around (im not moving, in screens i just turned right) object need to be faced still to player.
And when im scrolling, object is turning up or down.

that is why i like it

#

i like to think

#

i like code heavy work

#

its so satisfieing when you solve tough problems

timber tide
#

it's not so much just the pathfinding, it's how to make it so your units correctly path together (preventing deadlock)

thick jetty
#

yea. we had to do that in the reesearch group we are apart of, we had to make a drone AI engine to run drills with drones so we could plug them into actual embedded systems. it was tricky took like 5 of us to solve the issues of keeping them close together and not dragging off wierdly

Your assets have a resolution and that's what they will look like, and if you want to make them pixelated or something use a shader

remote path
#

Hello, I have a question. What is the best way to hide/use API keys from for example openAi from your project since if I push to a private repo on git, openAi immediatly blocks the api key

teal viper
remote path
#

How would other people on the project use the key if it is ignored/ not on the repo?

teal viper
#

Although, I feel like the fact that you're sharing it with other people is what makes them block it.

#

There's no way they can tell that you uploaded it to a private repo, unless someone else used it.

burnt vapor
#

That's what I did when I deployed my application, and using a compiler directive I pointed it to the environment variable rather than looking into configuration like is possible during development.

#

There are libraries that allow you to store these more secure, if you want.

ruby python
#

!code

eternal falconBOT
remote path
#

I never used environment variables before, how do they work?

burnt vapor
#

It just stores key-value pairs on the user's pc

#

By default you always have one in your application that determines if you are in development or production. I would guess Unity has a lot more

remote path
#

I figured, but the key-value need to be in the project then. Wouldnt that trigger the block again?

burnt vapor
#

It's not in the project, it's on your pc

remote path
#

So each person needs to add the variable to their system variables to be able to work?

burnt vapor
#

Yes, that's why you really only need to enable it for production

#

I'm assuming you guys don't develop on production

remote path
#

It is test project/ proof of concept

burnt vapor
#

But if you do it's as easy as calling a single command on the CLI

remote path

Mornin' all,

So, I'm having a really weird issue with driving my Animation Controller.

moveMax is set to 1.

In my actual movement code, the 'speedMultiplier' variable affects the speed that the character moves so I know that works (even though I know it's not the most elegant solution), but I can't figure out why the 'blendTreeValue' never goes above 1, and therefore doesn't play the 'sprint' animation

Would anyone be able to take a look and see if you can point me in the right direction as to where I'm going wrong please? 😕

        if (Input.GetKey(sprintKey))
        {
            speedMultiplier = Mathf.Lerp(speedMultiplier, 2, Time.deltaTime * animationTransitionSpeed);
        }
        else
        {
            speedMultiplier = Mathf.Lerp(speedMultiplier, 1, Time.deltaTime * animationTransitionSpeed);
        }

        if (Input.GetKey(forwardKey))
        {
            playerAnimator.SetBool("isMoving", true);
            isMovingForward = true;
            if (currentVValue < moveMax)
            {
                currentVValue = Mathf.Lerp(currentVValue, moveMax, Time.deltaTime * animationTransitionSpeed);
                blendTreeValue = currentVValue * speedMultiplier;
                playerAnimator.SetFloat("Vertical", blendTreeValue);
            }
        }

So I just want to avoid that and not have to constatnly create new keys

You can also remove whatever behaviour requires the key in development but it will make developing this harder is my guess

#

I might just use JSON for now and send them the file. Cross the production / enviro bridge when I get to it

#

Thanks for the help

burnt vapor
#

Why would you use JSON when environment keys are way easier?

#

It's also like, the whole point of environment keys to store private API keys and things like that

#

Its easyer than JSON? I will look into it. Never used them, that is why I just automatically went for json xD

I'd like to select CaseCliquée() on the second screenshot, but i can't, is it because it is a Button parameter ?7

image.png image.png
burnt vapor
#

So you will either have to call a parameterless method and then call that method, or find a different way altogether.

frigid flume
#

but i can't convert a string to a button name so i don't know how i could do

burnt vapor
#

You can also use .onClick.AddListener() on the button component to bind it directly rather than using the editor

#

Then you can pass parameters and you will also know what button is clicked

How can i destroy the clones that i instatiated from a prefab

modest dust
#

Destroy(the_clone_gameobject);

carmine elm
#

and the_clone_gameobject is what?

#

the clones are not instatiated when the game starts

icy junco
#

could someone please help me this is a small snippet of my code for aiming if(!aiming && Input.GetMouseButton(1) && canAim && !characterScript.isSprinting) { aimObject.GetComponent<Animation>().Play(AimAnimName); aiming = true; } if(aiming && Input.GetMouseButton(1) && canAim) { aimObject.GetComponent<Animation>().Play(AimReturnAnimName); aiming = false; }

the animation plays but the bool of aiming doesnt turn to true when aiming anyone knows why?

        {
            aimObject.GetComponent<Animation>().Play(AimAnimName);
            aiming = true;
        }
        if(aiming && Input.GetMouseButton(1) && canAim)
        {
            aimObject.GetComponent<Animation>().Play(AimReturnAnimName);
        }``` try this
modest dust
carmine elm
#

and how do i do this

modest dust
#

What exactly are you trying to do?

carmine elm
#

so i have a gun that shoots bullet and when the bullet hits an enemy it should destroy.

modest dust
#

destroy the enemy or the bullet

#

or both

carmine elm
#

the bullet

modest dust
#

What detects the collision, the bullet or the enemy?

#

Or both

carmine elm
#

sorry

#

just the bullet

modest dust
#

So the bullet does receive a OnTriggerEnter/OnCollisionEnter call, right?

carmine elm
#

yes

modest dust
# 
private void OnCollisionEnter(Collision collision)
{
  // Do stuff regarding collision
  Destroy(gameObject);
}
carmine elm
#

i understand that

#

but for example if i write : public GameObject bullet

#

i have to associate it with something in the editor

modest dust
#

Prefab?

carmine elm
#

yes

modest dust
#

Yeah, so what's the issue then

carmine elm
#

i should mentioned

#

i want to destroy the prefab clone

#

that will spawn

languid spire
#

that is what gameObject is

modest dust
#

Yes, Destroy(gameObject) will destroy the clone

#

gameObject refers to the GameObject instance the monobehaviour script instance is currently on

carmine elm
#

ok

vale cradle
#

i don't know why i am getting this error

image.png
#

this the the code where it is showing error on line 23

languid spire
#

not an error, a warning, read it

vale cradle
#

and this code is linked with another script i'll share that wait

vale cradle
#

this one

languid spire
#

so read it, it tells you exactly what the problem is and how to fix it

vale cradle
#

so i have to change it to private from protected

modest dust
#

If you want to call base.OnTriggerEnter2D(collision); you need to make the base method virtual and override it in the deriving class

vale cradle
#

on the other script i have set it like this : protected void OnTriggerEnter2D(Collider2D collision)

modest dust
# 
class Base : MonoBehaviour
{
  protected virtual void OnTriggerEnter2D(Collider2D other)
  {
    // Base stuff
  }
}

class Derived : Base 
{
  protected override void OnTriggerEnter2D(Collider2D other)
  {
    base.OnTriggerEnter2D(other);
    // Derived stuff
  }
}```
vale cradle
#

Okay i'll try doing this

#

it's working now thankyou @modest dust

Currently in a bit of a pickle. I've got an object here with a collider, and another larger one set to a trigger which is just used to get the colliders in proximity to the object. Initially I had set it in project settings so that raycasts do not hit trigger colliders, since I only want this onMouseDown to fire when the actual object is clicked. Here is a sort of gizmo I created that should be used to move this object around. Clicking on the object should spawn it in, then dragging the mover object should then move the object its attached to. However this mover collider is a trigger, so that the actual collider doesn't move objects around it shouldn't. But of course, I just set it so that I can't click on triggers.

The capsule object has a script that makes it so that when it is clicked, it will create this move and bind itself to it's position. Given I have two conflicting rules, what could I potentially do so that I can properly click on the mover and drag it, but the trigger on the capsule doesn't stop me from clicking on the capsule's actual collider?```cs
private void OnMouseDown()
{
if (hasPositionMover == false)
{
var obj = Instantiate(posMoverXZPrefab, new Vector3(transform.position.x, transform.position.y + 1, transform.position.z), Quaternion.identity);
posMoverXZ = obj;
hasPositionMover = true;
body.isKinematic = true;
var obj2 = Instantiate(posMoverYPrefab, new Vector3(transform.position.x, transform.position.y + 1, transform.position.z), Quaternion.identity);
posMoverY = obj2;
hasPositionMover = true;
body.isKinematic = true;
cameraMovementToggler.EnableRotation(false);

}
else
{
        Destroy(posMoverXZ);
        Destroy(posMoverY);
        hasPositionMover = false;
    body.isKinematic = false;
    cameraMovementToggler.EnableRotation(true);
}

}

void Update()
{
if (hasPositionMover)
{
if (prioritisedMover == MoverAxis.XZ)
{
transform.position = posMoverXZ.transform.position;
posMoverY.transform.position = posMoverXZ.transform.position;
}
else if (prioritisedMover == MoverAxis.Y)
{
transform.position = posMoverY.transform.position;
posMoverXZ.transform.position = posMoverY.transform.position;
}

    transform.position = posMoverY.transform.position;
}

}

#

why do you spawn in a separate "mouse mover" object?

#

ok i see, you click on the object, and then the point is you use the mover object to move it after that?

hidden sleet
#

Since I wanted to have movement in more directions than just paralel to the camera's current forward angle. I'd like movement in the XZ plane, and Y plane perpendicular to the floor.

#

Yeah yeah, so I click, they appear around the object, and those are used to move the object around more precisely

#

but the combination of triggers and colliders stopping OnMouseDown means that I either cannot move the mover at all, or clicking on the mover then thinks I'm clicking the capsule, which destroys the movers

low path
#

so the reason you set the ray cast doesn't hit on triggers is becauase you wanted the ray cast to hit your collider?

#

i mean your main object?

hidden sleet
#

The larger circle here is a trigger, the collider on the capsule is just one used for physics. I want clicking on the capsule to be what activates and deactivates the movers, but that trigger overlaps the collider of the mover so that you can only drag the edges, or else the trigger takes over the click response and destroys the movers. So yes, I wanted the click to occur only when I click that central collider, but implementing that seems to have made it impossible for the mover to be a trigger collider.

image.png image.png
#

thought I had an idea there but didn't work out

low path
#

well... my 2 cents is... try to do mouse clicks a bit differently -- do a ray cast from camera through mouse position. screentoworld(). you can specify in that call whether it will hit triggers. you can also use raycastall to get all hits and select the one you want.

https://t-machine.org/index.php/2015/03/14/fix-unity3ds-broken-onmousedown/ this post from a while ago indicates it might not be the best idea to use onmousedown for what you want to do, but i'm honestly not sure

hidden sleet
#

sounds good, was just thinking that but stopped half way through the sentence

#

I did see a couple folks here mentioning onMouseDown as being pretty bad, and it seems I've run into the exact situation that explains why X/

low path
#

yeah... i don't really do 3d but in 2d, i kind of do this stuff manually. and i'm sort of familiar with oni code from modding and they basically do a raycast to get all objects and cycle through them as you keep clicking so i think it might be a common solution to do a manual raycast.

#

i think you can also limit the distance of raycast all in 3d so that you don't get a whole bunch of objects in the distance... if that's what you want. again, not that familiar though

hidden sleet
#

I'll see if I can brainstorm some solutions

low path
#

You can make a mouse manager and give it a state machine. So it could have states like object selected, object not selected, etc. then your click handler will do what it needs to do based on that.

#

So if nothing is selected, you can for example get all non trigger objects that are selectable and maybe select the closest one.

#

This is how I do mouse stuff and more or less how oni does it. They have mouse “tools” that implement certain behaviors based on what tool is selected (e.g., dig, build, etc).

#

That’s a bit complicated for what you are doing but I think the idea of searching through a list of hits in a way that differs based on whether your object is selected could work.

hidden sleet
#

So I think I've got it now so it can do soething when the right trigger is clicked, but how could I implement the movement while dragging without the click then destrying the mover?

low path
#

Hard to say without seeing your code. What makes it destroy the mover?

hidden sleet
# 
private void OnMouseDown()
{
    if (hasPositionMover == false)
    {
        var obj = Instantiate(posMoverXZPrefab, new Vector3(transform.position.x, transform.position.y + 1, transform.position.z), Quaternion.identity);
        posMoverXZ = obj;
        hasPositionMover = true;
        body.isKinematic = true;
        var obj2 = Instantiate(posMoverYPrefab, new Vector3(transform.position.x, transform.position.y + 1, transform.position.z), Quaternion.identity);
        posMoverY = obj2;
        hasPositionMover = true;
        body.isKinematic = true;
        cameraMovementToggler.EnableRotation(false);
    }
    else
    {
        Destroy(posMoverXZ);
        Destroy(posMoverY);
        hasPositionMover = false;
        body.isKinematic = false;
        cameraMovementToggler.EnableRotation(true);

    }
}```
#

actually hold up, this shouldn't be an issue

#

unless it will continuously cast the ray while being held

#

okay, clicking it works with that. but now the movers don't move the thing X/

icy sluice
hidden sleet
#

it's not really a mouse cursor, more like two hovering UI elements that move the object on a flat plane and a vertical plane

icy sluice
hidden sleet
#

okay, for some strange reason clicking on one now activates both...

#

oh wait I see why, when I click on one, that'll fire the ray on the other object too, and since I clicked on this object, it spawns it in on the other one

Just do something like this: ModificationCase(yourButtonComponentHere, yourBool)

You probably don't need to pass in the button as a reference, it should be

  • a class level variable
  • cached in Awake with GetComponent<Button>()

Turns out after implementing this, it creates the movers on both objects instead of just the one. I assume that's because of the update and mouse button down stuff working on both at the same time. What would I have to do for it to just run this method on the object I actually click?```cs
void Update()
{

if (Input.GetMouseButtonDown(0))
{
    Ray mouseRay = Camera.main.ScreenPointToRay(Input.mousePosition);
    List<RaycastHit> hits = new List<RaycastHit>(Physics.RaycastAll(mouseRay));
    bool hasBeenConsumed = false;
    foreach (RaycastHit hit in hits)
    {
        if (hasBeenConsumed)
        {
            break;
        }

        if (hit.collider.isTrigger == false && hit.collider.CompareTag("Snappable"))
        {
            if (hasPositionMover == false)
            {
                Debug.Log("Mover Created");
                CreatePositionMover();
                hasBeenConsumed = true;
            }
            else
            {
                Debug.Log("Mover Destroyed");
                DestroyPositionMover();
                hasBeenConsumed = true;
            }


        }
    }
}

if (hasPositionMover)
{
    if (prioritisedMover == MoverAxis.XZ)
    {
        transform.position = posMoverXZ.transform.position;
        posMoverY.transform.position = posMoverXZ.transform.position;
    }
    else if (prioritisedMover == MoverAxis.Y)
    {
        transform.position = posMoverY.transform.position;
        posMoverXZ.transform.position = posMoverY.transform.position;
    }

    transform.position = posMoverY.transform.position;

A null reference means you've declared a var but not assigned it and you're trying to use it. Look at the console to find out which line this happens on , you can work out from that what hasn't been assigned

You can pass one parameter into a method from the button. If that's not good enough, you'll need to reference stuff that you want to pass to the method in the script.
