Game Development

and pls don't get on my case for trashing black ops, I was ready to love it but they increased the movement speed to where you outrun all zombies comfortably at a walk

jgallant

There are so many versions I have no idea what game you are talking about

It's the same version as you will find in this scientific sample

That's what you should buy

Also take note that in that purely scientific sample (which thankfully is rendered harmless without the "CoD5 v1.7 LANFix" patch) , they have unlocked nazi zombies minigame already. I think you have to beat the campaign or use a cheat code on a fresh install

@jgallant I trust you enough to ask, aren't there new games out? Isn't there some new better virtual place to shoot each other in by now?

Or cooperatively shoot at things in?

jgallant

Ugh I can't buy a game now

Just dropped 90 on Zelda

MickLH

... but

I tried. not my fault anymore

Don't come crying to me when you're all not virtually shooting realistic guns at realistic friends and stuff!

because I'll just be there, like pick up a gun, friend

I think I botched the emotional appeal

Chris McFarland

Zelda - waiting to see if the Wii U version is gimped or not
not sure if I wanna buy a Switch right away

Stephane Hockenhull

same

Twilight princess was fine on both

jgallant

2:36 AM

Supposed to be exactly the same except for 720p vs 900p

And switch has better SfX too apparently

Stephane Hockenhull

why would the switch have better sound effects?

Chris McFarland

dat audio processing

probably just has more sfx in the world

playing at once

jgallant

2:51 AM

Or they derped the sounds on purpose

there is also some footage of the 900p docked version, playing alongside the 720p undocked

and the 900p has some slight framedrops

but anyways from what I have seen the game looks amazing.

im' hyped

@Riva Probably the new Zelda

user92578

I had a more productive week than I remembered! Weekly write-up #48! blog.gunherogame.com/2017/02/26/…

#48, dayum

user92578

Looks like I started on Feb 28 last year

user92578

So I've only missed, what, 4 weeks or something

Chris McFarland

good stuff

André Marques

11:12 AM

hello guys, im new to game dev and im making an game for android whats the best way for me to save data in the device, data like what levels did he passed and what levels are unlocked, coins and other stuff

user92578

PlayerPrefs? IDK

Hjorthenify

Using Unity?

André Marques

yes im using unity

Hjorthenify

You can use PlayerPrefs, but that will cause some issues if you ever plan on shipping the game on steam

André Marques

i found something about player prefs but people say that can be easly edited by other people

user92578

11:14 AM

is your game single player?

André Marques

yes

user92578

then who cares?

André Marques

but it has the coins part and other stuff

that i dont want that can be editable

user92578

again, if the player wants to cheat and get those, why disallow him?

Hjorthenify

^

user92578

11:16 AM

if someone wants to, they'll break anything you come up with

Hjorthenify

There is no way to prevent cheating in SP

André Marques

hmm k thanks

Oliver Schöning

Do you guys ever draw stuff out on paper? I noticed it helps me a ton

user92578

like what stuff?

Oliver Schöning

To figure out gameplay, pathfinding and stuff

user92578

11:25 AM

well occasionally I draw something in GIMP but not very often

user92578

that might be because I have a level editor that allows for very quick iteration

user92578

so I can just open it up and test

Oliver Schöning

Thats great! I havent gotten to the point yet because I still need to figure out if my """""art style""""" is working for the game.

user92578

that character looks awesome though

Oliver Schöning

You think so? :D I really like that style haha

user92578

11:27 AM

lol yeah, kinda reminds me of castle crashers

Oliver Schöning

Yeah I was thinking that too after I made him haha! I had an old drawing I have been trying to re-do into something that I would be capable of animating

user92578

are you gonna go for bone animations or just draw frames?

Oliver Schöning

Frames I think. Because performance / ease. This is a one person project and I really gotta cut corners where I know I don't excel. For now at least

user92578

sounds reasonable

Oliver Schöning

I picked this style also because I then only have to draw left / right sides. Instead of 4 or 8 versions

I am gonna flip him but I want the arms to be on the correct side

user92578

11:32 AM

right

Oliver Schöning

So right now I am testing it out on paper, just to see if it would look horrible if I attack diagonally or upwards

I think he needs to do a short movement in that direction while attacking.

Hello

yahoo5000

is it something wrong with my tint function or i understand tinting in wrong way ?

tint by 255,0,0

Hjorthenify

What is tint

user92578

how are you tinting?

yahoo5000

tinting

user92578

there are multiple ways of shading

yahoo5000

12:12 PM

Surface Graphics::TintSurface(const Surface & surf, Color tint, bool alfa)
{
	Surface result(surf.GetWidth(), surf.GetHeight());
	result.Copy(surf);
	int yend = result.GetHeight();
	int xend = result.GetWidth();
	if (!alfa)
	{
		for (int y = 0; y < yend; y++)
		{
			for (int x = 0; x < xend; x++)
			{
				Color cl = result.GetPixel(x, y);
				cl.SetR(std::min(255, cl.GetR() + (255 - cl.GetR()) * tint.GetR()));
				cl.SetG(std::min(255, cl.GetG() + (255 - cl.GetG()) * tint.GetG()));
				cl.SetB(std::min(255, cl.GetB() + (255 - cl.GetB()) * tint.GetB()));

user92578

I think what you're looking for is just multiply shading

yahoo5000

yea i was hoping if i am tinting by pure red it would be red not a pink

also one thing i made this function with alfa and was calling without and still it tint only visible pixel not a transparent once so i guess i should not care about alfa right ?

user92578

you want Color = (A * B) / 255

yahoo5000

ok lets try this , what about alpha do i need to add to counting ? or just forget it ?

i mean those pixels who are fully transparent if i tint them it will still be fully transparent so there is no point to worry about alpha i guess

user92578

yeah, in image editors alpha affects the result though

Hjorthenify

12:28 PM

What are you all up to?

user92578

I'll probably continue working on my content "obfuscation" system

Chris McFarland

Awesome!

user92578

damn I'm sure I had something to ask you Chris

Chris McFarland

got lobby client and lobby server connections going at least today too

Hjorthenify

12:30 PM

Niiiiiice

Chris McFarland

hrmm

user92578

wtf was it

Hjorthenify

Hey Chris how do you move your entities?

user92578

this wasn't it but did you add Steam DRM to TM?

Chris McFarland

@Hjorthenify like creatures?

Hjorthenify

12:30 PM

Yeah, using force or what?

Chris McFarland

@Tyyppi_77 nah. I added a check that, if the game isn't connected to Steam for some reason, just displays a warning message that leaderboards and achievements won't be triggered

@Hjorthenify I generally alter transform.position directly

yahoo5000

Tyyppi tnx works just fine :D

user92578

So you weren't "worried" about people just copying the executable around?

user92578

np, happy to help

Hjorthenify

@ChrisMcFarland Aha.. I've been doing that as well, but this is a space game so direct force manipulation might be better..

yahoo5000

12:32 PM

what about  this is more for shading ? or what i found this formula on google

cl.SetR(std::min(255, cl.GetR() + (255 - cl.GetR()) * tint.GetR()));

Chris McFarland

@Tyyppi_77 for a $5 singleplayer game... meh lol

just go buy the DRM-free copy anyway

@Hjorthenify mmm yeah depends on the movement you're trying to achieve

Hjorthenify

Yeah.. I like that you have to "accelerate" first, but then again force is hard for very precise movements(which I need)

I guess acceleration can be achieved using lerp as well

user92578

hmm all right yeah I don't think I'll bother either then

cool!

yahoo5000

now need to marge with database

Hjorthenify

Why does it change colors like that

yahoo5000

1:29 PM

its based on population

user92578

I added a navbar to my website and threw the old awful social icons out

Hjorthenify

Ahh

yahoo5000

i made player to be able to know how many people of specific country are playing on each of regions so they would be able to play with they own country players

and of its low then just will be green if avarage will be blue and if alot red

Hjorthenify

Oliver Schöning

2:09 PM

Have you guys checked out the Crystal programming language? Worth a peek.

jgallant

2:28 PM

You should interpolate the color change

Stephane Hockenhull

Cristal. Yet another language ...

Oliver Schöning

No one said it's a standard tho. Just a neat language.

Stephane Hockenhull

cat xkcd | sed s/standard/language/g

Stephane Hockenhull

3:32 PM

It's getting ridiculous the number of languages out there that are invented almost exclusively for creating web services.

And most of them with horrible language designs.

user92578

3:44 PM

All right it seems like I have all my content loading from a zip file all nice and clean

Stephane Hockenhull

nice.

user92578

That was way easier than I anticipated, all though part of that is definitely the fact that I already did most of it earlier and now I just had to fix some issues

Stephane Hockenhull

I both look forward and dread reaching that stage :P

user92578

This is something that I probably wouldn't have known how to do like a year ago, but for slightly more mature Tyyppi this wasn't extremely difficult :)

Stephane Hockenhull

LOL

user92578

3:48 PM

heavy emphasis on "slightly"

Stephane Hockenhull

vec3 points[4];
points[1] = points[0] = selection_points[0];
points[3] = points[2] = selection_points[1];
Swap(points[3][0], points[1][0]);

I am not proud but neither am I ashamed :D

lazy way of turning 2 points into a rect poly :P

user92578

that's actually pretty cool but it does require some thinking

user92578

Just put it into a neatly named method and then it's something that you should be proud of

Stephane Hockenhull

I should probably make a template, or make a DebugRect function instead of using DebugPoly ...

or both

...
later

WHY WAIT WHEN YOU CAN PROCRASTINATE TODAY!!!

START PUTTING OFF THINGS FOR LATER NOW!!!

user92578

lol

user92578

3:54 PM

a dude was asking how to implement a cache for a facebook profile pic that can be used in his game

Stephane Hockenhull

furk I forgot DebugPoly works in UI space and I'm dragging in world space.

user92578

I commented "what's preventing you from just loading the image like you are right now and sticking it into something that is accessible from everywhere that needs the image"

user92578

he replied "haha I guess nothing" and deleted the question

Stephane Hockenhull

globals are fine if they're actually for global concepts.

I had a global array of gamepad input structs so player AIs could read each player's input and one for the local gamepad.
Worked fine for 3 years until some dude fresh out of school was all "Globals are bad mkay?" and decided to replace it all with callbacks that had to be registered for each buttons with separate callbacks for press and release.

user92578

ouch

user92578

4:00 PM

my input system is a global mapping thingy and sometimes it's really nice and sometimes a huge pain

Stephane Hockenhull

So rather than just check a bitfield every AI that wanted to read inputs had to register 2 callbacks PER BUTTON and not forget to unregister them.

And all they did in their callbacks was to update/reconstructing their own private bitfield

And the old system had automatic key repeats, and double taps, and time since last tap, and key logging for exact replay during debug session, and secret code/fireball processing.
New system had none of that.

But the new system didn't have a publicly accessible global! Progress!

it just took about 100x the amount of memory (on a Nintendo DS mind you), and had none of the features of the old one.

Good luck debugging a networked game when you can't run it in offline replay mode anymore.

Hjorthenify

Why is this vector reflection thing giving me so many problems..

Stephane Hockenhull

Because it hates you.

You shouldn't have hooked up with vector reflection's sister.

3D vector-plane reflection?

Hjorthenify

2D

I "fixed" it, problem were whenever my reflection vector were pointing opposite the normal vecetor

Which I still haven't fixed, but made kindof a workaround which is fine imo

Hjorthenify

4:29 PM

FIXED

After lots of trial and error I figured out that I need to reflect the vector twice :P

Stephane Hockenhull

wut? Isn't that just negating the direction?

Hjorthenify

Yes it is, which is exactly was I was doing by my "fix"

So now that I've come to this conclusion I will go back to my "fix"

SE used to be my favorite site on the internet, but now that Politics.SE has opened it's also the most disgusting site, surpassing even 4chan by a large margin.

See with regular shitposting sites, it's just kinda funny... but when the people making shitposts are actually just regular people thinking they are making useful contributions, it's a really scary and depressing commentary on society.

Stephane Hockenhull

And a waste of time. Politicians don't care about politics.SE. It doesn't line their pockets.

MickLH

I personally consider it another pure clickbait SE site. The only utility of it is to host flamewars and circlejerks, and help people procrastinate from actual useful tasks so they can do themselves minor emotional trauma instead.

Stephane Hockenhull

LOL

yeah

yahoo5000

Question: I have 5 regions and 5 columns with maximum height 200px how to calculate height of each of them so they wont extend the limit of 200 like if total population of whole 5 regions is 50k

each of region have different ammount of population but i think i need to calculate from total

MickLH

@yahoo5000 By definition something with maximum height 200 will not extend past the limit of 200. You're welcome.

Stephane Hockenhull

6:02 PM

divide each regions by the total, put that into a float (0.0f .. 1.0f) and use that float to scale to your 200px

yahoo5000

if i have 5 regions with : 10k 8k 6k 15k 12k , dividing them from 200 wont give me right result ? or i got u wrong

MickLH

are you only trying to show relative levels? or absolute?

yahoo5000

relative

MickLH

Then take the largest one as x, now multiply all of them by 200, and divide all of them by x

If x is zero then skip the divide step

The most populated bar will always be 100%

(The rest will scale with it relatively)

yahoo5000

yea i think thats what i want would be good enough i guess

Stephane Hockenhull

6:07 PM

float height[5];
float max = 0;
float regions[5] = { ...};
for(int i=0; i < 5; ++i){
max = max > regions[i] ? max : regions[i];
}
if(max == 0) max = 1;
for(int i=0; i < 5; ++i){
height[i] = regions[i] / max * 200;
}

find the max, divide everything by that max and multiply by your max height (200).

MickLH

^ and if you have a good guess at how much population you need for any of them to get "full" then you can pre-load the max with that value

yahoo5000

hmm its oposide then Mick told or its the same result ?

MickLH

It's the same

yahoo5000

ah yea sorr :D

ok guys tnx will do this

Stephane Hockenhull

Note that I'm forcing max to 1 if it is zero, that means all regions are zero so it doesn't matter that we're dividing by 1 it'll still give zero.

MickLH

6:09 PM

I should explain that last part better, I mean that if you want them to require 1k population before any of them get full, then you can inject 1k into the max calculation.

If the max is "too high" it's fine, it'll just mean that no bars are 100%

yahoo5000

ok tnx a lot

You can rocket jump and fly in the air and throw rockets and blow stuff

Also you can fly in the air somewhat like no-clip for 5 seconds, 12 seconds cooldown.

I worked somewhat extensively on movement control. It feels good.

MickLH

if it has netcode I will 1v1 you right now

coming soon~~~~ (does have net code but not ready for 1vs 1 test :( )

I'm not judging if I should run it in a debugger :P

I have vs on win7 and gdb on linux / mac but the mac has a shitty gpu

Dang mick, your enthusiasm to help me test my game is so moving. U know what? I will get it ready for 1 vs 1 by... next week!!!!!!! yes!!

I'm glad lol, though you don't have to change your whole schedule if you were working on something else first

but still... catch me in game tho

Blue Bug

8:27 PM

I am godlike when it comes to FPS games. adds cheat button shhh...

MickLH

lol it's fair if you also tell me the cheat buttons

though I consider map-knowledge based one-way damage flow scenarios that are grossly beyond the nominal advantage factor over the playable map surface as essentially equivalent to "cheat buttons" also

Blue Bug

That sounds more like good map awareness or something more like "defense vs offense maps" where defense team has spacial advantage.

MickLH

In that case I'd assume the map design that sets a large advantage over a path to a defense area, will also leave another path that eventually compromises the advantage of the first path
