Weird camera movement in 2d, flickering maybe? Not sure.

[lost socket]

Hi, I'm new to godot coming from unity, I'm following a tutorial but I didn't want to go the pixel perfect route and I tried to make my camera smooth and not have neither the camera nor the player/enemies toggled to snap to pixels which I think might be where my problem comes from.

I can't exactly put my finger on what is wrong, but I'm feeling the camera feels weird when I'm moving around, as if things are flickering, maybe sort of bad antialiasing.

I thought it was fps issues at first but I put a counter on the timer at the top and it seems to be holding at 60 just fine... Any ideas on what it could be? Or shouldl I just give up on my smooth camera and snap everything to pixel and hope for the best?

Thanks,
Dan.

Also this is a "build" version

[naive topaz]

camera settings - smoothing.
By default the smooth speed is about 5 pixels per second i think. double or triple that
sorry its an long time since i was working on my project. AND
Turn on pixel snap in project settings

[lost socket]

It is 5 indeed, will try your suggestion thank you ^^

[naive topaz]

no problem

[lost socket]

So... it fixed the flickering issue, but now the movement specially when I go diagonally is very jaggedy, not sure what word to use hahahha

[lost socket]

ohhhhh thank you!!

I'll test that out later but I'll change it to solved, thank you ^^

[naive topaz]

i am bad at coding but good at research

no prob

When moving a CharacterBody2D, you should not set its position property directly. Instead, you use the move_and_collide() or move_and_slide() methods. These methods move the body along a given vector and detect collisions.

[lost socket]

Oh yeah the tutorial I'm following has me using move_and_slide

[naive topaz]

👍

[lost socket]

extends CharacterBody2D

@onready var animation_player: AnimatedSprite2D = $AnimatedSprite2D
@export var max_speed: float = 100
@export var acceleration_speed: float = 25

# Called when the node enters the scene tree for the first time.
func _ready():
    animation_player.play("Idle_Down")

var moving_animation: bool
var looking_up: bool

# Called every frame. 'delta' is the elapsed time since the previous frame.
func _physics_process(delta):
    var target_velocity: Vector2 =  get_movement_vector().normalized() * max_speed
    velocity = velocity.lerp(target_velocity,1.0 - exp(-delta * acceleration_speed))
    
    looking_up = true if velocity.y < -0.2 else false
        
    if (velocity.x > 0.1 and not animation_player.flip_h):
        animation_player.flip_h = true
    if (velocity.x < -0.1 and animation_player.flip_h):
        animation_player.flip_h = false
        
    var is_moving: bool = abs(velocity.length_squared()) > 0.05
    if (is_moving):
        moving_animation = true
        animation_player.play("Walk_Up" if looking_up else "Walk_Down")
    elif (moving_animation):
        animation_player.play("Idle_Down")
        
    move_and_slide()

func get_movement_vector():
    var x_movement: float = Input.get_action_strength("move_right") - Input.get_action_strength("move_left")
    var y_movement: float = Input.get_action_strength("move_down") - Input.get_action_strength("move_up")
    return Vector2(x_movement,y_movement)

Got this at the moment, will implement the solution on the reddit thread

[naive topaz]

do you test out how fast the player is moving in diagonal directions ?

https://www.youtube.com/watch?v=0cYjreg7dpg

and i found an secound solution when you scroll down here he talks about Camera Jitter in Godot http://saint11.org/blog/consistency/

thats all i found

ah and someone said

Limit the player character to a set of directions, specifically 8, some diagonals will just look chunky if not a perfect diagonal or straight.

Create another vector, when you go to apply input apply it to the accumulator, when the accumulator on either axis is >= 1.0 add the integer to the players velocity or position without the fraction. And then subtract the integer from the accumulator.

On changing directions or stopping set the accumulator to 0. This will ensure the player only moves to exact pixel positions (be wary of diagonal walls that aren’t aligned to a pixel grid)

When wanting to move at a sub pixel speed apply it to the accumulator NOT directly to the player.

and here dont know you can see it or not https://discord.com/channels/212250894228652034/1152036368248221799

[lost socket]

Ohhh that makes sense, I definitely didn’t do that

Also didn’t see that, yay ^^ thanks

I had to run out of the house for something, excited to try these things later ^^ thanks again, super appreciated. Loving that the community here is super supportive

[naive topaz]

someone make it and showed everyone that was from unity

no problem

i am not an coder

more an problem solver and game designer

i am afk now and watch twitch and play holocure

when you need something just ask

[lost socket]

I feel now the pixels are staying crisp and sharp with no flickering, I feel that now the camera feels weird for a whole different set of reasons, but I feel I can live with that actually. 😂

I think it's good xD

thanks again \o

[naive topaz]

ok when you make an game with masses of enemies it would be an good idea to center the camera on the the player but when the player moves in any direction the camera should be a little ahead of the position of the player so he can see where he is going. and when he stops the camera should center again , so i am afk at work

[naive topaz]

so i am back

finally i have weekend

ah also i found an thread with the diagonal movement looks laggy thematic https://www.reddit.com/r/godot/comments/15kof9c/how_to_fix_jitter_when_moving_diagonally_while/

[naive topaz]

by the way when you have FPS problems, just deactivate VSync this can push the FPS by 500% or even more........ i dont know why

and that it dont fuck up your fps you can set your own limit Check in project settings -> debug -> settings -> force fps (0 is uncapped, any other number is the max fps)

here is an other good tipp: https://www.reddit.com/r/godot/comments/yzsq08/tip_got_a_stutterdropping_frames_in_your_game/

[naive topaz]

i also just ask here an another game dev with an pixelart 8 x game #1150384015854030969 message

[naive topaz]

@lost socket

[lost socket]

I got it working perfectly already, this is a more recent gif ^^ thanks though

[lost socket]

Oh that’s good to know, makes sense: limiting fps is good though to keep gpu/cpu usage down

[lost socket]

Ah!! That’s great so I can say how much fps I want, perfect ^^

[naive topaz]

always aim for 120

[lost socket]

Thanks!! ^^ appreciated

[naive topaz]

because when you game gets more complex

you can get minim 60

[lost socket]

Yep makes sense ^^

I’m pretty excited, gonna try doing a grid inventory today

[naive topaz]

and have you seen what i wrote about camera aim ?

[lost socket]

Kind of a zero siervet one

Yeah I have

It makes sense

Will probably do that later

[naive topaz]

not only it helps player see visually where the small player character is looking it also gives you an better aim at distend enemys

do you use godot 4.x or 3.x ?

@lost socket

[lost socket]

4.1

[naive topaz]

https://www.youtube.com/watch?v=qLrj_HWA9CI

[lost socket]

Ohh perfect!!! That will sure be helpful ^^

Thanks ^^

[naive topaz]

problem is there are so much good tutorials in different forms but because there are not so much godot games that are aaa you didnt find godot specific thing in the top 10 of gamedev search

do you want an single box inventory where every item uses the same space or an loot-tetris like inventory like in diablo or path of exile ?

[lost socket]

Loot-Tetris like but I already planned how I’m achieving it, the tutorial you linked is perfect, shows me what I need to know about Godot so I can achieve my plan

[naive topaz]

https://www.youtube.com/watch?v=WN40PrPRDXs

[lost socket]

I’ve already made the inventory in Unity, I’m going to remake it in Godot essentially the same way, just needed to know how to setup the UI and get the right signals out of it xD

[lost socket]

Nice ^^

[naive topaz]

as i said there are solutions for nearly everything in godot but they are bad archived

[lost socket]

Hahahah makes sense

They’re all over the place xD

[naive topaz]

yes what it makes hard for totally new beginners in gamedev field

i made never an game only hundred of concepts on the other hand i am good in problem solving so i help gamedevs

i know you an person with alot of knowlage of the gamedev field

but no one knows everything so i help anyway

so dont misunderstand my help efforts that i assume you dont know an specific thing

[lost socket]

I appreciate it ^^

No worries, it’s appreciated xD

[naive topaz]

same gamedevs get angry fast and write something like "you think i dont know that ? do you even made something like XYZ before ?"

ok

some gamedevs are in an buggle where they dont play anymore and miss some new trends and even advances that would help thier game

so i think the angry attitude comes a little by this situation

[lost socket]

I think it’s a big ego

[naive topaz]

and this is not an add when you work on an complex project maybe with more people use something like an shared mindmap or trello https://trello.com

[naive topaz]

maybe

[lost socket]

I try my best to be humble and aknowledge there’s a ton I don’t know, I feel I don’t have a big ego 😂

[naive topaz]

dude no problem i mostly work at high logic ......... i cant do what you have done in the last 7 days

[lost socket]

I believe I have undiagnosed adhd, I can’t live without tasklists hahahahha everything I need to do/remember goes on a task list, I use Todoist https://todoist.com/

I’ve tried trello and other solutions before, this is the one I love the most ^^

[naive topaz]

i save every pearl from the internet in specific folders in my browser favorites......... so i can use them in the future i guess ?

[lost socket]

My favourites are a big mess 😂 I tried using pocket to organize things a bit better but also became a mess

I end up making a little note on my phone with the link when I really want to remember a link, that way I can at least search in notes

[naive topaz]

i always also have over 50 tabs open in installed an side tab tree extention so i see all of them at the left and not on the top

this goes nice with an wide screen monitor

[lost socket]

That’s interesting 😮

I always have a ton of tabs open, drives my girlfriend crazy for some reason 😂

[naive topaz]

i use firefox since the last 20 years i think

extension is called "tree style tab"

https://github.com/DanielSnd/godot-gspreadsheet-importer/
Working on my inventory I converted my old google spreadsheets importer I made for unity to use with godot, decided to make it available for free on github to give back to the community ^^

[naive topaz]

looking good

do you make something like diablo,zelda,binding of isaac or vampire survivor ?

@lost socket

[lost socket]

The plan is to make something like zero siervet xD

But it started following a vampire survivor course on udemy hahahaha

[naive topaz]

i like project zomboid and zero sievert

the whole genere is lacking arcarde gameplay and friendly look

i think this can work

[lost socket]

Exactly! ^^

[naive topaz]

so will it have an story or is it mission like where you keep the loot when you survive ?

@lost socket

[lost socket]

Good question, at first it's mission like where you keep the loot when you survive.

Have to get to a place and stay within an area for X time to be extracted alive.

And you go building up a "base" with the stuff you're looting in the dangerous levels.

Unlocking stuff as you progress and, unlocking more levels to go to

Won't have time to work too much on it for the next couple months though, but I'm excited ^^

[naive topaz]

you need to see the axolotl game an steam i think its an mix of zelda and vampire survivor (not sure) but people have mixed feelings about it becauser rough like players want more vampire survivor and zelda player want mod adventure and less stress.

i search for it

most people find it and water down version of Gungeon

soundtrack and visuals are great

but most people dont know what the game want to be

[lost socket]

It does look pretty cool will have to check it out ^^

On the private Nintendo developers forum got access to a repository with a version of Godot that builds for the switch ^^ pretty excited, I was worried about console porting with Godot

[naive topaz]

godot itsself can be changed

the whole engine can be modded

[lost socket]

Yeah that’s nice ^^

[naive topaz]

so an good programmer that can use c# can fix everything an dev team needs or find themself, that the biggest advantage this engine has.

[lost socket]

Not C#, C++

C# is limited to the mono version, and even so doesn’t work on consoles/mobile/web, very limited

To edit the engine and make literally anything you’d need to use C++

Which unfortunately I do not know 😂 but I’m now thinking of learning

[naive topaz]

sorry i mean c++

@lost socket

when you need help with item/skill ideas and the balancing of them just ask

[naive topaz]

i dont have time at the moment to make one of my game concepts reality but i can help with yours.

afk

[lost socket]

I got a game designer working with me but thank you for the offer ^^ I appreciate it

I’m working on a multiplayer experiment now, making a little node js web sockets server with “rooms” so players can join rooms and play together kind of mimicking the experience of using “Unity Relay” but on Godot.

Just slowly building up the things I need to fully transition hahahah

[naive topaz]

how much can join an "team" ?

i mean 4 player coop strugle because statisticly mopst people only have 2 very close friends

@lost socket

[lost socket]

I'm thinking up to 4

[naive topaz]

hmmm i would make 4 optional and 2 minimum

so an team of 3 dont get unbalanced

[lost socket]

Nah, singleplayer minimum, up to 4.

[naive topaz]

wait the singleplayer is also the multiplayer setting ?

[lost socket]

Yeah

[naive topaz]

ok i search for an golden rule you dont break when scale the SP to MP

i search for it wait

ah "never scale HP of enemy's and don't let them heal" "let spawn more enemy's,let them make new moves,let them hit harder and reduce good loot chances"

many coop games just make enemys harder to kill and some can self heal but its getting boring real fast.

@lost socket

[lost socket]

fair xD

[naive topaz]

Gunfire Reborn Coop was also fucked up because they ignored the rule

do you need an financial overview over 90% of the steam games and what kind of game they are ?

town there are tabs have fun

and yes everyone can make thier own copy

@lost socket

[lost socket]

Oh that's cool 😮 thanks

[naive topaz]

no problem

as i said i collect things that are helpfull

Ember Knights, is one of the best coop rough like out there but it had two flaws that let the wave of new players stop....... the price-contend ratio.
Most players have seen all and mastered it after 10 hours.Nearly all player discribed it as well balanced and really fun but lack of new players(paywall) and lack of new contend(to early released) I hope they get their momentum back with some updates.

[lost socket]

Ember knights looks so good ;o

I haven't played it yet

Haven't been playing much lately at all actually 😭
