alwasy talk about your game

every chance you get

►

2:23 AM

wow, I haven't written hardly any code today.

I just keep staring at it and hoping for...inspiration, or something...

that is horrible

good morning

@IcyDefiance play some heroes of the storm

I could...

you could

:)

2:37 AM

sure why not. I'm not getting anything done anyway.

ok

how do I find you on battlenet

you can add me by email

if you want

that or battletag (at the top of your friends list, the thing with the number after your name)

almo2001@yahoo.com

3:37 AM

color blindness test

4:35 AM

@Almo game crashed -.-

:(

try to reconnect?

working on it

5:47 AM

people are friendlier in hots than in league

yeah

the play mechanics are freindlier, and there's no allchat

you can't even steal regen globes

you can take them too early so someone isn't close enough, but that's about it

eh, I seldom see any toxicity in all chat. it's mostly jokes there. toxicity always comes from my own team (and me >.>)

but there's no "I have 17 kills as talon but the rest of you can't do shit"

if one person does well it takes the rest of the team up with him

"takes the rest of the team up with him" true

9:09 AM

@KevinvanderVelden what about Jon Skeet??

Q: Jon Skeet Facts

I'm looking for Chuck Norris Facts style answers. In case anyone is curious, this question was inspired by Jon's own comment to this question. EDIT: If you're into cryptography, you may enjoy these facts. Now with official sanction from the powers that be!

user92578

9:35 AM

@Sword Jon Skeet is a C# guy I think

he does Java as well.

And C++, by chance??

user92578

So how's it going? Making progress with Java?

his daily work is in Java (80% of his work time) for Google.

yo

user92578

hey

9:42 AM

tyyppi how is your poject going ?

project*

user92578

quite good, I did some menu work yesterday and even though I'm not perfectly happy with it yet I now have a lot cleaner way to add menu functionality

user92578

Currently I'm designing the area for my boss battle

user92578

Then I'll get to programming the boss AI

Sounds good. When do you think it's going to be finished?

user92578

No idea... it needs a lot of content, as I currently only have one level

user92578

9:45 AM

but in a simple state it depends a lot of how much I'm going to get done

user92578

the gameplay itself is quite complete

user92578

but I have exam week starting on wednesday which means I need to use most of my time to reading school books

user92578

This is pretty much what I did yesterday:

user92578

user92578

Not quite happy with the header label color

9:49 AM

@Tyyppi_77 will this be out for android and ios?

user92578

No

user92578

*probably not, as the controls are not simple enough to be usable on mobile devices

@Sword he knows all of C#, not all of C++

is C# comparatively smaller to C++ ?

user92578

Yeah

9:51 AM

the hard part with c++ is to learn all the small details on when something is allowed

user92578

and all the optimizing tips, like "you should pass all boolean pointers as references to const pointers to ints, as that makes the program run a lot faster"

the actual features and the library can be learnt in a few years of usage

@Sword C++ has 32 years of development in it, plus all of C

not even sure if that's a good optimization, it feels like it could be done by the compiler but it's the first time I'm hearing about it so I will take your word for it. Most optimizations usually come by utilizing copy/move semantics and cache friendly techniques.

user92578

lol, that's not a real thing

user92578

but like const references are

If the answer to a question is "you (currently) can't", is it better to accept it or to leave it unaccepted? While the "you can't" may be the correct answer now, it might easily change in future: if the asker leaves the question unattended it will be better not to have an accepted one, rather th...

user92578

Hmm I lost all my motivation

'sup ?

user92578

I'll just play a bit and look for some dev blogs to gain the lost motivation back

Chris

have you added sound effects?

user92578

no

user92578

10:38 AM

that's actually something I could look into

Chris

try it, they help make things feel better

Yeah, I can blit images again

Now to clean my house and then if there's time left make rendering of tiles :D

11:02 AM

I am trying to slide my car to the right linearly ; and it should look continuous.. But my approach instantaneously places my car at the desired point without the visible transition.

a sample:

public void slide(float deltaTime){
        mainPosition.x = main_sprite.getX();
        while(mainPosition.x>100){
            mainPosition.x-=0.0005;
            main_sprite.rotate(20);
            main_sprite.setPosition(mainPosition.x,100);

only the x matters.. y coord remains constant..

the inbuilt function "translateX" also dint seem to work.. Any suggestions would be awesome for me.. :)

Uhm

Don't do it in a while loop that won't let a new frame be rendered until the loop is complete?

The inbuilt function works just fine, you're just calling them many many times

translateX also works the same.. the sprite disappears from its position and appears at x=100. I want to make it smooth.. So should his method be called inside a while loop?

No

None of it should be called in a while loop

The while loop is "Do this, do not render a frame, do not handle input, until this condition is met"

ohhh..

so ...

So, yes, it is moving it in steps of 0.0005, it's just not rendering it because you told it not to

11:10 AM

an if statement?

Yes, an if statement would work

right.. I tried different denominations of the -= and it dint work.. I was after the wrong thing the entire time

thanks.. :)

Np

user92578

11:36 AM

So currently my camera system finds the center point between the players and centers the camera on that

user92578

This results to that all the players disappear off the screen at the same time if they get too far from each other

user92578

But I don't think that's a good think

user92578

so what should I do on those cases? pick a player, and follow him instead of all the players?

user92578

something else?

Invisible wall is what most games use

Just don't let the players go that far away from eachother

user92578

11:38 AM

Sounds good

user92578

I wonder how I can implement that

Uuh, if abs( player.x - center.x ) > *magicnumber*: player.velX += *magicnumber*

user92578

are the magic numbers the same?

(And take care of people being on the other side of the screen and the Y axis)

No no

You don't suddenly want to add a few 100 to the velocity =p

That's a bad idea

user92578

Shouldn't I just stop the movement if the player is at the border instead of moving it to somewhere?

11:50 AM

You could

But I generally think that it's more fun to be pushed back than to just be stopped

user92578

right

You could also make it so that the farther away from the limit you are the more you're pushed back

user92578

hmm my velocity isn't reset every frame so it just keeps on sliding

It feels more, fluid

@Tyyppi_77 there's no drag?

user92578

?

11:53 AM

Hmm well that's tricky, plan B! Stop them when they reach the border

Drag (physics)

In fluid dynamics, drag (sometimes called air resistance, a type of friction, or fluid resistance, another type of friction or fluid friction) refers to forces acting opposite to the relative motion of any object moving with respect to a surrounding fluid. This can exist between two fluid layers (or surfaces) or a fluid and a solid surface. Unlike other resistive forces, such as dry friction, which are nearly independent of velocity, drag forces depend on velocity. Drag force is proportional to the velocity for a laminar flow and the squared velocity for a turbulent flow. Even though the ultimate...

user92578

ah, fancy stuff

player.vel *= 0.9 also workd

But you'd have to redo pretty much your entire movement so probably a bad idea at this point

user92578

aight it works now... kinda

user92578

as I lerp the camera value, the players can go offscreen for a few frames before the camera reaches the limit position

Is that really a problem?

I like that kind of thing

user92578

11:57 AM

oh, then it isn't

Also. NO: BAD KEVIN, CLEAN THE HOUSE, THEN GAMEDEV

Afk again :)

BAD KEVIN

user92578

I'm supposed to vah-coom the house too

user92578

user92578

12:00 PM

How about on the Y? I can't just limit that as it'd look weird if the player was limited from dropping in mid fall

Lasse

I'm supposed to vah-coom too but I'm too hungover to do that :(

damn friday parties

user92578

lol

user92578

but you're an adult, if you don't want to vah-coom, you don't have to

user92578

hmm my internet is having problems with tigsource images again

@Tyyppi_77 you do if you have visitors coming =p

user92578

that's true

That's such an excuse.

12:14 PM

@Jon hello :)

sup sword

better than that day :)

that day

the day he pooped his pants

i ate.. .now i'm logging into work for some OT

No idea what kind of game I should make.

12:24 PM

@William'MindWorX'Mariager yes, that fudging day..

Kenney at it again

I think your username should be shorter.. :\

@Jon is it a spritesheet?

yah

kenney.nl

looks like spyhunter

12:28 PM

added screen wrap today as well.. Just need to fix the part of sliding..

yeah.. Spyhunter will be the next game.. First one without any shooting..

why not ?

David Blaine Street Magic: YouTube Edition!

its pretty good stuff

12:41 PM

@Jon nice...

12:55 PM

what could be an alternative to the while loop? I am using the if condition but that just checks it once ..

something like keep doing it until this.object reaches this point...

user92578

just put that do the check every frame

user92578

void Update() { if (xPos != targetPos) xPos += velToTarget; }

sounds like you may be looking to create an event

I tried using a boolean flag

@Tyyppi_77 looks cool. but what if it misses the targetPos , for example if targetPos is 100 and xPos transits from 105 to 95..

and it will perform the action once

it will check whether it is equal or not , perform it once and out...

I'll try a for loop here

user92578

if (abs(xPos - targetPos) < closeEnough)

1:10 PM

for loop did not work as well. It rendered the entire stuff in a single frame and it looked as if the car teleported..

user92578

You didn't get the point I think Kevin already pointed to you

user92578

Do you have an update method, that gets called every frame?

yes.

user92578

so place the code I gave you there and it'll do the thing every frame

user92578

move the car a bit by bit

1:12 PM

so I shouldn't use the slide method inside update?

2 hours ago, by Sword

public void slide(float deltaTime){
        mainPosition.x = main_sprite.getX();
        while(mainPosition.x>100){
            mainPosition.x-=0.0005;
            main_sprite.rotate(20);
            main_sprite.setPosition(mainPosition.x,100);

user92578

Don't put loops in update

user92578

@Sword The while loop will perform the action during one frame

yes ; im not using it anymore after kevin pointed it out

user92578

replace the while with if, and call the slide from Update, and you should be fine

the slide method is called in the update method

user92578

1:13 PM

show me your code

this comes in the update method

if(mainRect.overlaps((collideRect))) {
                stopflag=false;
                stability = false;
                isColliding = true;
                enemyGroup.get(i).stop();
                mainCar.decelerate(deltaTime);
                mainCar.slide(deltaTime);

the last line invokes slide

user92578

and is this not currently working?

user92578

what does your slide look like?

wait let me update that and check

public void slide(float deltaTime){

        for(;main_sprite.getX()>=100;){
            mainPosition.x = main_sprite.getX();
            mainPosition.x-=15;
            main_sprite.rotate(20);
            main_sprite.setPosition(mainPosition.x,100);
        }

this is the same as while..

user92578

IF

1:16 PM

so I'll just put in your changes

user92578

NO FOR, NO WHILE

user92578

IF

cannot resolve method "abs" and Intellij isn't prompting me to import anything for "abs"

user92578

that was pseudo code

ohhh

user92578

1:18 PM

just replace the "for" in your code with "if"

user92578

and try that

it executes only once

and it moves by 15..

if ((main_sprite.getX() - 100) > 2){
            mainPosition.x = main_sprite.getX();
            mainPosition.x-=15;
            main_sprite.rotate(20);
            main_sprite.setPosition(mainPosition.x,100);
        }

it satisfies ; executes once and out of the method..

user92578

and this is called from your update method every frame?

yes

user92578

how about instead of 15 use 1?

1:20 PM

maybe the problem is with : if(mainRect.overlaps((collideRect)))

because when it collides ; that sprite is removed and the flag changes..

user92578

yeah

@Tyyppi_77 that is just the step size.. wont make a difference

I guess I'll need a boolean flag to sort this one out..

user92578

visually, yes it will

user92578

no you probably dont

user92578

just call the slide() every frame, not depending on collisions and such

1:23 PM

lol, its doing a moonwalk now..

:D

the slide is ok.. The problem is that if(overlaps) thing lasts for a short duration only..

So i'll trigger a flag and the flag will reset once the car slides to the intended position..

user92578

sounds good

yeah.. last resort.. otherwise will ask it on the site.. I guess the problem is obvious now

Thanks @Tyyppi_77; you deserve a medal

user92578

Why ask on the site? We should be able to solve the problem really easily here

user92578

@Sword thanks :)

got to run.. afk..

me too, cya

TheMuffinCoder

1:42 PM

lol Icy

That was so true, i had to fix my CSS xD

user92578

2:23 PM

So how should I handle the Y difference in my camera?

user92578

I can't do the same as I did for X (players hitting an invisible wall, can not walk out of the camera view)

user92578

as that would result in weird mid-fall stops

Here for 10 seconds

@Tyyppi_77: Your problem is that the players are to far away from eachother right? Well, don't allow them to go higher than 3/4 of the screen, and just let them go offscreen

They'll find their own way back

(Maybe point an arrow if they're off scren)

And now, groceries!

@Tyyppi_77, I haven't been reading the conversation so sorry if this is a stupid answer, but what about clamping the position within the camera?

user92578

What do you mean?

2:38 PM

will your game have deep pits?

where the players can fall into?

user92578

Yeah, the height of the level will vary

user92578

Players can have large differences between Y values

and I guess zooming out isn't an option

user92578

No, that isn't something I want to do

the only things i can think of are pointing the arrow at the player that's not visible, like Kevin said, or you could split the screen when they become too far apart

user92578

2:40 PM

Yeah, I'll probably do the arrow thing

user92578

I just need to think about what to actually show

why don't you split the screen?

user92578

It'll make the screen estate too small

user92578

also I will have different amounts of players

oh

user92578

2:41 PM

I just need to probably focus on one player when the players get too far from each other

user92578

Because showing the center point that possibly doesn't show a single player on the screen is not beneficial

wait, how many players could you possibly have in a hotseat context?

user92578

and then display arrows for rest of the players

i doubt there'll be like 20

user92578

@toby 4 at max currently

2:43 PM

and the resolution the game will be running ont?

on*

user92578

well depends on the window size/monitor resolution

user92578

currently at 1920x1080

i'd go for something that tiling window managers do

have the 'main' player take most screen

and the players that are too far take sections of the rest

this way, at least they can see where they are

not just arrows

user92578

not a bad idea

user92578

I'll see what I can implement and what will work the best

user92578

2:46 PM

I'll try out the arrow thing first

that looks better realtime than early pixar movies.

yep it still does look awesome

the only thing that made me believe it's real time is the fact that you can (some times) see the mesh LOD changing

that's why steam is harmful

where were you when steam is kill

3:55 PM

@Tyyppi_77 so gun hero multiplayer is ready?

user92578

Well you can currently have two players locally playing the same game

user92578

Now I'm trying what split screen would look like

user92578

and more players can be added once I get key binding stuff working

i love coop games

believe it or not

user92578

4:00 PM

damn I was gonna try to have some silly fun but my mind keeps hitting me with the real this morning... I need to expand my company, put all the handshake clients on contracts, and hire a few people

i just want to work on my own projects... I'm spending so much time dealing with relationships that I basically don't even get to code anymore

kinda wish there was an SE for how to work less but keep the life you want

user92578

Okay I quickly hacked the split screen together (and don't look at the non-centered HUD panels), and it looks okayish:

user92578

The movement isn't smooth etc, but it works quite well

user92578

Of course when the players fit to the same screen I'll use only one camera

I am taking a break today and tomorrow from working on my game

there's a bug with the local notification (cosmetic) and I'm NOT working on it :)

user92578

4:16 PM

So what do you guys think? Split screen or invisible walls when players try to walk too far from each other?

if you do invisible walls, you really have to get the camera and display of that situation right

depends on gamepplay implications

it's tricky as hell to do well

even Dead Nation had a difficult solution, but it worked reasonably well

camera seems to look at the center point between you, and a circle appears when you get near the limits of how far apart you can get.

@Tyyppi_77 Not bad

Seems like the kind of game where I would want ants to hold the invisible walls

user92578

ant?

Look again :P
