Yeah

Pip

nice

Hjorthenify

9:01 PM

Yo dawg how do I use System.Print to write "Hello world" in that black box?

hasherr

It's kind of a gimmick how they call themselves Fiverr, because Five isn't what you make, it's what you spend

@Hjorthenify That'll be $5 first

Hjorthenify

But .. but..

hasherr

NO BUTS

SUBMIT A GIG REQUEST

Grey

hash is gonna be the first one to reach the pizza fund challenge

Hjorthenify

You already made enough for a pizza! Can't this one be on the house? :(

hasherr

9:02 PM

@Grey I already did

Grey

shame

hasherr

@Grey Dat's right tho

@Hjorthenify Alright. Sell me your soul and I'll give you a dollar off

Grey

@Grey Shipping and Handling

What

Grey

Charge for him to ship his soul

Hjorthenify

9:04 PM

@hasherr I have already sold my soul for a pizza once...

Grey

and you need a special vase to store it

to keep his soul in your possession

you must chant: golmerificus totalis 5 times a day in the vases presence

Very high maintenance souls are.

My partner hasn't got on yet

Bagofsheep

Hey guys, anyone in here experienced with 2d player movement, maybe some basic physics?

Grey

I'm getting worried

Pip

some

hasherr

Pretty much everybody here, yeah

Pip

9:05 PM

@Grey who is your partner?

hasherr

what

Grey

@hasherr gtfo

hasherr

???

Didn't even say anything, brah

Grey

THE HISTORY

Pip

yeah, Hash is correct. Most of us are fairly experienced in 2D physics and player movement

hasherr

9:07 PM

wait what

Pip

stobbit

Bagofsheep

Haha alright. Well in my top-down game I'm implementing more natural movement for the player with acceleration and drag. It works well except for one small thing. If I don't comment out the two bottom if statements the player instantly stops when releasing the keys (though he accelerate fines) but if I do comment them out I get weird behavior where it is near impossible to change direction sometimes:

if (oldKeys.IsKeyDown(Keys.A))
velocity.X = -1;
if (oldKeys.IsKeyDown(Keys.D))
velocity.X = 1;

Serial

It isnt letting me push?

@Pip

Bagofsheep

Velocity is simply the direction the player is moving since in the move() method is gets normalized.

I know my way of handling it is primitive.

Pip

what do you need nao? um... do you have the remote repository set up, locally?

Serial

9:09 PM

git remote add origin ChristianCareaga@bitbucket.org/ChristianCareaga/…

Pip

@Bagofsheep I have some reference for you

gamemechanicexplorer.com/#

that should work

Serial

tried that and get fatal: remote origin already exists

Pip

oh......

alright

Bagofsheep

I saw that link the other day. The problem with that is in the code he uses some sort of phaser physics engine or something.

So all of the code isn't being shown I think.

For physics anyways.

Pip

not for the concept

but the physics is all there

Bagofsheep

9:10 PM

Alright.

Pip

do git remote add PygameGUIs (link here) @Serial

then use that instead of origin when pushing

did it work?

wait @Serial

don't do that

do:

Bagofsheep

I see. He is directly modifying the velocity direction with the acceleration but the way my move method is setup does not allow for that since objects can move in 360 degrees.

public virtual void move(GameTime gameTime)
{
setOldPos(position.X, position.Y);

if (velocity.Length() > 0)
velocity.Normalize();

velocity = Vector2.Multiply(velocity, CurrentSpeed);
position += Vector2.Multiply(velocity, (float)gameTime.ElapsedGameTime.TotalSeconds);
}

Serial

It worked

Pip

git remote rename origin oldorigin

then git remote add origin (link)

Serial

It did two first commits though haha

Pip

9:14 PM

lol

is it a private repo?

Yeah

add me pls

whats your username

same as everywhere else :P

Serial

nevermind

Pip

9:16 PM

lol

Serial

There

Grey

@Pip stop teh cyber bully

Pip

thanks

@Grey ?

Grey

(talking abot hsh)

Pip

ah

Jon

9:22 PM

ok, later

cya man

Later.

@Grey i am not cyber

@Serial that looks..... really good already

hasherr

@Jon Wait did you die?

Grey

9:23 PM

@hasherr ur cybr buli

hasherr

@Grey NO I NOT

Grey

ok

Serial

Thanks! I can add comments

Pip

a request: when you continue working on this, can you inform me when there is a new version? Also, tell me if it will break my game, I will have to fix my game if that happens

@Serial :)

Serial

It should work for your game

Pip

9:25 PM

not what I meant :P

I mean, if the new versions would break my game, if using an older version

Serial

huh

Pip

like, if you change the values required to instantiate the GUI item

or change their orders, etc

Serial

All you have to do is create a class that inherits my Frame class, then create widget instances and tell them what to do using methods

there is a Test class in Example.py

Pip

again, not what I meant :P

say I am using your GUI

and that version requires x, y, and z to make a new instance

if a new version requires z, y, x (or x, y, z, and a), that would break the current implementation

Icy Defiance

programmer vocabulary of the day: breaking change.
http://en.wiktionary.org/wiki/breaking_change

Pip

9:29 PM

there we go

that is what I meant @Serial

Icy Defiance

from the link, see also: backward compatibility. make that the second vocabulary of the day.

Pip

that one I knew

Serial

Oh No I understand, I was just explaining how to use it

I get exactly what you mean

SpartanDonut

Also its worth note that if you are collaborating, don't commit anything that doesn't build. If you aren't collaborating, don't upgrade the version you are using if you don't want to risk something breaking

3

Pip

alright

Serial

9:30 PM

ill tell you when I update it

Pip

kk

Icy Defiance

@SpartanDonut isn't that what branches are for?

Serial

Its not very pretty right now but its just for testing, Images can be used

Icy Defiance

just don't merge to master until you know it's working and it passes all your tests

MickLH

@IcyDefiance yes.

Pip

9:32 PM

@Serial nice. I may just use the button class, etc, you already made

SpartanDonut

Yeah but when the merge happens if you break the main branch you are breaking the rule I was talking about. It doesn't really change anything

Icy Defiance

mhm

Serial

@Pip well they kinda go with the Frame but you can alter them

Pip

:)

hasherr

Man, this is the most fun I've had programming since Ghostly.

Working on a fun project with a team and doing Fiverr gigs on the side

Pip

9:33 PM

do is all I do instantiate a button class, after import? Does it require pre-initiating, like pygame.init() does?

hasherr

And Pizza!

Pip

@hasherr which project? MT? or something else?

hasherr

My other project

Pip

ah

we have to have a meeting sometime

Serial

@Pip well all the widget's first parameter are Frame, and thats what they are blitted to

but you could make a frame as big as the screen and just make it transparent

or change the widget code

hasherr

9:41 PM

Hey guys

Guess

What

I get my CPU this week! :D

Hopefully either Wednesday or Thursday

Lasse

"this week"

I keep forgetting your week starts from sunday

that's weird man

hasherr

When does your week* start?

Lasse

how can a week start from sunday

monday

Seth Battin

when i hear "this" in the future sense, I always assume the meaning is the week about to come

hasherr

Oh

Hjorthenify

9:43 PM

Does that mean hasherr actually enjoy monday when the rest of us hates it?

Lasse

probably

hasherr

No, I hate mondays

My schoolweek/workweek starts mondays

But I've always seen Sunday as the beginning of the week

Hjorthenify

O_O Thats... Different!

erebel55

lo

Pip

@Serial so, could I pass it one of my "screen's" surfaces? My game has several screens, and the dominant one (controlled by the Game() class) is the one shown on screen. Could I pass the screen surface based on which screen it is on, then?

hasherr

9:44 PM

SU->M->TU->W->TH->F->SA

Pip

@hasherr same here

that is the US way

hasherr

Huh, must be an American thing

erebel55

if i add a like me on facebook or follow me on twitter button to my game do i have to follow any kind of standard for the button image?

Pip

just use their logo, or the like symbol, or etc

Seth Battin

9:46 PM

@erebel55 they have pretty strict rules about it, actually

Lasse

@hasherr the difference is, your calendar has sunday on the first column, while ours has monday there

Icy Defiance

@erebel55 that's...actually a good question. but I don't think so. give me a minute, I'll try to find something about that.

oh Seth might know

Seth Battin

I do

must use their assets

must not deface their assets

erebel55

i've see a lot of different variants for it.

Seth Battin

must not alter the implication of clicking on the button

erebel55

9:46 PM

a lot of people are doing it wrong than

Hjorthenify

Any advice on optimizing particle collision? Right now when I render ~200 particles my FPS drops by 30 (to 50fps) :/

Lasse

@Hjorthenify use a grid

Seth Battin

you MAY change the appear to match the style of the site, but only insofar as it matches all other social media icons

Lasse

or quadtree

hasherr

@Lasse That's dumb

Do it right

Seth Battin

9:47 PM

most of these are also true for google's buttons

Hjorthenify

@Lasse My world is too small for a quadtree :P

@Hesherr How is it done right?

Lasse

@hasherr no, it makes perfect sense, that's when the week starts and you go back to work

erebel55

"but only insofar as it matches all other social media icons"

what does that mean?

Seth Battin

in both cases, there are ways to add the like, et. al without actually coding any of it

it means, say you make the like button really small

you can't have, right next to it, a giant reddit button

erebel55

gotcha

Seth Battin

9:48 PM

but if you search for the rules, you'll find them. i might be comflating facebook and google anyway

erebel55

for example, if i had a facebook and twitter buttons like the one at the top of this page in my game i would be fine?

monkeycoder.co.nz/Community/_index_.php

Seth Battin

that is ok, yes

erebel55

okay cool, it makes sense than

thanks guys :)

Pip

mhm

Icy Defiance

@erebel55 if you actually want to read the details, I believe this is the relevant page: developers.facebook.com/policy

Pip

9:49 PM

I saw your question there from 11 mins ago @erebel55

:P

Seth Battin

like Icy said

read the rules to be sure

erebel55

thanks Icy

Seth Battin

if you can, just use a pre-built widget to acocmplish whatever you can

customizing is usually unecessary, and lots of work

for example, this silly page i built for byte56's game...lots of effort to make the social icons where i needed them and identical itsobviously.com/newkorbly

totally not worth it :)

hasherr

@Lasse You wrong.

Serial

@Pip the Frame is a class and it updates the widgets and everything so not but you could change the code to make it so that the button can go straight onto the screen

Icy Defiance

9:56 PM

@SethBattin and then Ghostery just blocks the buttons entirely. :D

I love Ghostery

Serial

@hasherr what's that fivver thing?

Seth Battin

@IcyDefiance yeah, it's too bad there isn't an oauth service that people trust without worrying about losing their lives to it

cause they're really, really convenient to use

and safer than passwords for everything

Icy Defiance

I just don't like Facebook knowing every site I visit

Seth Battin

ha, true

the trick is to log out :)

Icy Defiance

log out and change your IP address after logging out

Seth Battin

9:59 PM

perhaps so

Pip

@Serial I would rather not change the code, if I don't have to. Should I just make a Frame for each screen, then?

Lasse

yay got my raycasting working

Serial

You can make multiple frames

look at the example class

Lasse

turns out my original version had nothing wrong

Pip

kk

Icy Defiance

10:00 PM

google's no better though. and there are a few other trackers that seem to light up on freaking everything.

Ghostery and Disconnect just block them all

Lasse

but thanks to @MickLH the new version is a bit faster

Icy Defiance

Gravatar is another one. I can't see 1/2 the avatars in this chat because Gravatar logs the IP address of anyone who accesses an image from their servers.

so Ghostery blocks all Gravatar images

interesting

that's kind of silly

can you see mine?

10:01 PM

yes I can

Seth Battin

by definition, a server logs ip addresses

Icy Defiance

not quite the same

Seth Battin

it's what they do

yeah...

Icy Defiance

Gravatar apparently keeps them around and tracks what you do on the internet. It's mentioned in their privacy policy if I remember right, but it's not like the policy is shown to you before you load a picture.

actually I'm a little surprised that Imgur doesn't do that. or at least it's not known that they do.

Lasse

but you can read it when you start using gravatar

or does it actually log the non-users ips too?

Icy Defiance

10:04 PM

it does

or so the claim goes

I haven't looked too deeply into it

Serial

wait how do i make multiple lines show up as code in chat?

Lasse

@Serial click on the fixed font button next to send before you hit enter

Pip

yep

Serial

nope

Lasse

you didn't click the fixed font button before you hit enter

Serial

10:05 PM

class Test(Frame):
    def __init__(self, screen):
        ''' An example class to show how to creat custom GUI frames'''
        Frame.__init__(self, screen, (250, 250), (0,0))

        self.b1 = Button(self, "Button1", self.command)
        self.b2 = Button(self, "Button2", self.command2, position=(10, 100))
        self.b3 = Button(self, "Button3", self.command3, position=(10, 190))

        #do something

    def command2(self):

there

@Pip that's an example of how to make a frame

Pip

kk

@Serial I made a branch called "pip_dev"

going to work on that a bit later, if I have time

Lasse

is there a spoiler tag or something like that on SE post? So that I can hide some text if I don't want it to be shown without user interaction, for example when posting spoilers, or in this case I want to edit my project highlights post and leave old text hidden, to allow readers to focus more on the new text

Pip

I don't think so :/

feature-request mode activated

:P

Hjorthenify

Holy shit sin and cos are slow in C++ o_O

Lasse

@Hjorthenify are they really?

Seth Battin

10:16 PM

depends on the proc

they can be fast

Hjorthenify

@Lasse Very! Remember how I asked how to optimize a particle system? I rewrote my particle class to use use a vector instead of cos(angle) and sin(angle) Now my FPS only drops by 4 when rendering 200 particles...

Lasse

I haven't noticed any slowdowns with C# when using them

but I have never used them like you described

Icy Defiance

using them in a particle system could do it

Lasse

I have always had a vector based movement

Hjorthenify

I didn't either. I used them for unit movement since they change direction often, so the code was pretty much just copy-pasted...

Now that it uses vectors it is much more effecient!

Icy Defiance

10:24 PM

I think my particle system gives a start location, direction vector, "force" vector (gravity, wind, etc), and current time to the shader, then each particle is a vertex with a position and spawn time. the shader does all the rest of the work.

been a while since I looked at that project

Lasse

sounds like it's hard to implement something dynamic there, like what happens when some force source is slapped on the scene after couple of seconds

it would change every particle's path

Icy Defiance

yeah it wouldn't support changing wind speeds

it did support moving emitters, with a boolean deciding whether the particles would inherit the emitter's velocity at the point they were emitted

oh and the shader got a rotate speed too, which also wasn't dynamic

Lasse

anyway, that must have been fast :)

Icy Defiance

could draw 1.2m particles at 60+ fps on my Radeon HD 7870 XT

on school computers it was more like 90k at 60 fps XD

Lasse

yeah

lol

hmm now how do I re-enable the chunk compression in memory, my current raycasting implementation needed to break that

Pip

10:33 PM

@Serial problem

what is pygame._view?

It throws a 'not found' error

Grey

    if(CS.Input.IsButtonDown("MouseScrollwheelUp")) then
        fov = fov - 1
        end

    if(CS.Input.IsButtonDown("MouseScrollwheelDown")) then
        fov = fov + 1

        end


    if(CS.Input.IsButtonDown("Mouse3")) then



        end
      fov = math.clamp(fov,44,60)

      local tempfov = lerp(self.gameObject.camera:GetFOV(),fov ,self.timer*2)
      self.gameObject.camera:SetFOV(tempfov)

hasherr

@Serial Fiverr*

Grey

This is causing my fov to warp in and out p bad. not sure how to fix it. Lerp is correct... is it my clamping?

hasherr

@Serial It's a website where you post a 'job' and then people can request your job and they pay $5

I've been facing some minor success from it lately

fiverr.com

Icy Defiance

@Grey what is fov before what you pasted here?

is it defined inside that function?

Grey

10:40 PM

yes fov is initalized to the current fov of the camera on "awake" which is 45

what i posted is in "update"

and craft studio does not have delta time so it's creator told me to calculate delta like so since the frame runs at 1/60

Icy Defiance

oh okay, so if you had scrolled up, then fov would equal 44 when it gets to the clamp function?

right before the clamp function, that is

Grey

self.time = self.time + 1/60

@icy

actually

I think clamp should be before all the "input" handling

Icy Defiance

@Grey check for int division errors with that

1.0/60 != 1/60

I dunno. the fov variable is the only thing that really looks suspicious to me. that's all I got.

Grey

(not sure why its choppy) but

I zoom in and it basically "zooms in and out really fast" before MonoGame(which is what CS is built on top of) throws ArgumentOutOfRange exceptioon

Icy Defiance

oh I bet I know

the time parameter for lerp

it's supposed to be between 0 and 1

Serial

10:46 PM

@Pip oops just delete that line in all the files my bad

Pip

lol

Icy Defiance

oh and self.timer != self.time. check that too, just because your messages are inconsistent there.

Pip

what does it do @Serial?

Grey

@IcyDefiance it's timer :P

@IcyDefiance I am sure I tried this but no dice. I'll try again

Serial

It does nothing I just copy and pasted it from an old project, It was originally for making a game into an exe but it isnt needed @Pip

Grey

10:48 PM

It's the clamp!

I think that's the jitter problem

Icy Defiance

quits

Grey

This one should be more representative

It make no sense

such fail

Icy Defiance

Oo

oh wait

you're scrolling up and down a bunch of times in that gif, right?

and each time the impact gets bigger and bigger

Grey

No

Same direction

Icy Defiance

Oo

can I see the whole function?

your bug has pissed me off

Grey

10:52 PM

function Behavior:Update()
    self.timer = self.timer + (1.0/60)
    TargetPos = Target.transform:GetPosition()
    Pos = self.gameObject.transform:GetPosition()
    Position = Vector3.Lerp(Pos, TargetPos, 0.2)
    PadPosition()
    self.gameObject.transform:SetPosition(Position)
    self.gameObject.transform:LookAt(TargetPos)
    Rot= self.gameObject.transform:GetEulerAngles()
    self.gameObject.transform:SetEulerAngles(Vector3:New(Rot.x,0,0))


    if(CS.Input.IsButtonDown("MouseScrollwheelUp")) then

@Icy thanks for helping. I'm guessing it's something simple, because I've run into a lot of bugs like that the past 2 days

Icy Defiance

wait you said fov was defined in the same function

Grey

nonono

Icy Defiance

oh you didn't say that

Grey

yes fov is initalized to the current fov of the camera on "awake" which is 45

It's in awake

Icy Defiance

okay
