@Pip glad you started the topic

Icy Defiance

okay, so I have a Mesh class, which just contains a list of vertices
and a Model class, which contains a Mesh and a Position
I want to add a Texture. should the Texture belong to Mesh or Model?
(in the future, Model might contain multiple Meshes, and multiple Textures may be mapped to each Mesh, if that makes any difference)

wait, nvm, answered my own question. if a mesh is drawn in two locations with different textures, I don't want two different mesh objects, I'd rather have two different models

Icy Defiance

00:49

textures now working

Almo

cool :)

I'm trying to ask a question about modding Garry's Mod with Lua. For example, this one I have posted. I am stuck between this site and Stack Overflow, because Stack Overflow has a garrys-mod tag, whereas this site does not, but this site is more for modding and developing games. Can someone tell me where these questions belong?

Icy Defiance

uhh, could go on either site tbh, though I'm not sure it'll get an answer on either site

you should narrow down the actual problem a bit more, because right now it looks like you're asking us to solve the whole project for you

if you do narrow it down more, the site it belongs on might become more clear

user146722

@ASCIIThenANSI when I played with SourceMod the idea would have been hook the object's collision, when it collides with something get the position and then weld it to what it collided to

ASCIIThenANSI

@SelflessPsychopath So what I'm looking for is to detect collisions, then call a function when it detects something?

user146722

@ASCIIThenANSI SDKHook_ShouldCollide

user146722

that was not Lua though

ASCIIThenANSI

01:18

@SelflessPsychopath Doesn't matter, I was looking at the problem wrong. ENT:PhysicsCollide( Table :CollisionData data, Physobj physobj ) is a built-in function for GMod Lua that controls what the object does when it hits something. Thanks for the help!

user146722

You're welcome

Hey guys whats the name of that program you guys use to make quick gif's of your games?

nvm found it :D blog.bahraniapps.com/gifcam

Scaling method is perfect and I can now use AA on it :D

Other scaling methods fully disabled AA

Almo

01:59

@IcyDefiance speccing you, in for next game

user92578

06:34

Morning

Lasse

very good morning

Hjorthenify

07:04

Morning

user92578

I feel like I was treated unfairly yesterday

Hjorthenify

How so?

user92578

Selfless attacks against my game ("not a real game", "this must be a learning project" etc.), and I bite back and get suspended

Chris

:(

Hjorthenify

Oh wow

user92578

07:11

But I decided that my future conversations will be Selflessless

Hjorthenify

:P

Chris

I muted him

cuz yeah

user92578

Me too

Hjorthenify

@Chris I've tested your game on 4 devices

Chris

ah yes

Hjorthenify

07:12

Worked like a charm :)

Chris

excellent, thanks

I'm going to try seeing about getting it as a free DLC for the Steam version

no guarantees but that's my plan atm

Hjorthenify

That would be awesome

Chris

Apple's just approved my v319 version for iOS, so I'm in go mode to get this launched

Hjorthenify

@Tyyppi_77 I think your game looks amazing. It really seem like a game I would enjoy to play once finished. He was most likely just jealous :)

Nice!

user92578

@Hjorthenify Thanks for the lift-up :)

Chris

07:15

yeah Tyyppi, your game is looking good man

don't let the haters bring you down

Hjorthenify

Did I mention I've nearly finished my inventory system? :)

Got organizing items, moving from one container to another and load/save to work yesterday

Chris

awesome

Hjorthenify

Yeah, but Unity is behaving weird and resize my GUI when I launch the game

Chris

cuz the resolution changes?

Hjorthenify

Probably.

Chris

07:28

does your Canvas have a CanvasScaler? if it's not set to Constant Pixel Size it's gonna change

or you can try the other scaling modes

Hjorthenify

Hmm

That did something :P

Right now my GUI is larger than my canvas until I run the game.. Then it's all good

Chris

I've got two canvases (canvi?)
one for text mainly with constant pixel size, and another canvas for my weapon wheel that stretches with the screen height
the wheel's text at the top doesn't always fit very well but meh

Hjorthenify

I see. Mine are not really required to scale with the screen size, but I have two canvas as well one for HUD and another for just GUI elements

user92578

08:24

I need some help with my slipping logic

user92578

I implemented raycasting yesterday to figure out what is underneath the player

Hjorthenify

Yes?

user92578

So I think that I'll need three rays? One from each bottom corner of the player and one from the center

user92578

The corner rays will figure out what is the player standing on top of

user92578

And the middle one will indicate if the player is on a ledge

user92578

08:25

Does this seem like a good approach?

Hjorthenify

Does your ray calculate the collision normal?

Chris

yeah that's similar to how I do it

feet, and just in front of the character to see if there's floor or not

Hjorthenify

If not then yes it's a good idea.

user92578

No it doesn't

user92578

I was also wondering (because I've never done rays before) what kind of results do I want from a raycast? A list of all the boxes that were checked with the distance (0 meaning no collision), or perhaps just a list with the boxes that had a ray collide to them? Something else?

Hjorthenify

08:28

The latter

user92578

My current method takes in a ray and an area to check against, and returns all the boxes that were checked against the ray

user92578

Okay

Hjorthenify

You should only return a list of objects which the ray collided with. You could care less about the other stuff as the player wont collide with them.

user92578

Right

Hjorthenify

Might want to add some kind of bit flag system for the collisions as well

user92578

08:56

Problem narrowed to the intersection code

user92578

I wonder if I should start debugging that or just pick another algorithm

Hjorthenify

09:15

What's your current algo?

user92578

Something Mindy gave me

user92578

Now I tried to get the slab method working but it's giving me false intersections

Hjorthenify

Mindy?

user92578

William "MindWorX" Mariager

Hjorthenify

Ah

Ask him then :P

user92578

09:19

Well I think his algorithm should work

user92578

I doubt he'd give me a broken one

user92578

I think it works now

user92578

Yeah it does

user92578

It's nice and really subtle, you don't really even notice it

user92578

Except for the fact that you can't hang on a ledge with one pixel on the ground

user92578

09:24

Which I think makes the game more polished

user92578

Maybe I could even add a small delay and an animation to warn the player from slipping

user92578

But the coolest thing is that I now have working ray casting!

Jesus Christ

@OMGtechy Yes? Why did you call me?

Hjorthenify

@Tyyppi_77 It's the little things that counts :)

user92578

Yeah, the little things that the user will never see :D

Hjorthenify

09:33

:D

Math assignments are... Boring.

Chris

lots of little things the user never sees, but really there are so many things

Hjorthenify

@Chris Anything in Tallowmere?

Chris

I guess really it's every component just doing its thing to make the game happen

floor checks, wall checks, line of sight checks, velocity things

Hjorthenify

Ah yes

Chris

a tiny line of code can have a big effect

user92578

09:38

@Hjorthenify yup

Hjorthenify

@Chris

if(player.HasDied);
Anim.Start("Died");

Get it? :P

Chris

that's how bug happens eh
miss one little thing lol

Hjorthenify

Yeah haha

I did that in a loop once when I was new to C++... Spend about half an hour tracking it down :D

Kinda silly it's a valid statement though

Chris

those are the worst bugs, when they still execute
but the effect is incorrect or missing

silent horrors

Hjorthenify

Yes. Also the bugs where you remove some code and suddently you got a bracket wrong..

Chris

09:42

haha yeah, I am paranoid when deleting

I often just comment things out and then only delete the comments in later versions once I'm sure I don't need it again

but even just accidentally highlighting a line too far

Hjorthenify

Haha me too! One of them slipped for me yesterday though so my items wouldn't get deleted if no other items had been changed (looped through an item and depricated list)

Chris

fun

user92578

@Hjorthenify Is this like a Unity thing? I don't get it

user92578

Or is HasDied() a method?

Hjorthenify

Spot the error, Tyyppi.. :P

user92578

09:45

oh the semicolon

Hjorthenify

Yup

Typpi are you making all the art yourself?

Chris

time for me to record and make a gameplay trailer to complement this bad boy

user92578

Your game looks so awesome

user92578

std::vector<TLevelRayCollision> GetRayCollisions(const CLevelRay* ray, const CBounding* area, std::vector<TLevelRayCollision>& result = std::vector<TLevelRayCollision>()) const;

Hjorthenify

drolls

user92578

09:48

This is illegal

user92578

How would I create a default argument for that?

Hjorthenify

Looks a bit photoshopped though, Chris :P

Around the borders

user92578

I want a reference because I like to optimize code by re-using class member vectors

Chris

@Tyyppi_77 :D

It's Google's Android promo art maker thingy

Hjorthenify

@Tyyppi_77 emplace_back ?

Not really sure what you're trying to make

Chris

09:49

developer.android.com/distribute/tools/promote/device-art.html

Hjorthenify

Ahh

It won't be noticed :P It's just me looking at it from a critic's perspective

user92578

Like I would call that by defining a std::vector<...> in the caller, and passing that as a reference to the method

user92578

But there might be a case where I wouldn't want to do that

user92578

Then I would like the method to just create a vector for me and return that

user92578

So, sometimes: GetRayCollisions(ray, area, placeResultsHere);

user92578

09:51

And sometimes: auto results = GetRayCollisions(ray, area);

Hjorthenify

Just stick with one way

user92578

Okay

Hjorthenify

If you go for speed do the first one

user92578

Yeah

Hjorthenify

and pass a reference

You can't return a reference if the object was created in the caller

user92578

09:53

Right

Hjorthenify

@Chris The more I look at that picture the more I want to buy it :D

Also great choice of screenshots!

Chris

hehehe

Hjorthenify

@Chris How did you implement the movement of the stun nades?

Just made them turn lazy? I've done this before, but I am really asking if there's an easy way to do it in Unity :)

Chris

I think it's just a velocity force at the start, then gradually they move towards the hero faster and faster

Hjorthenify

Well.. That was easy.
I thought they worked differently :P

.. But that would explain why they can't be dodged :)

Chris

10:24

yeah

Blue Bug

11:01

@Chris There are "review videos" of your game on Youtube. I am so jellyous.

Chris

it's cool :D

Pip

:D

Hjorthenify

Wow.. @Chris
Youtube stats: Tallo makes tallowmere the first seach option,
773 results come up and more than 2.000 combined views of the let's plays

William 'MindWorX' Mariager

11:18

@Hjorthenify, Don't be a stalker you weird Dane ...

Hjorthenify

Dont make me reveal what i have on you, Dane

user92578

@William'MindWorX'Mariager Thanks one more time for your ray code, it made the ray casting implementation painless and a lot quickier!

William 'MindWorX' Mariager

@Hjorthenify gasps

@Tyyppi_77 You're welcome. :D

But you should really be thanking SlimMath: code.google.com/p/slimmath/source/browse/trunk/SlimMath/…

user92578

right

William 'MindWorX' Mariager

The two methods are modified 2d versions of their 3d methods.

user92578

11:23

yea

user92578

I didn't actually (yet) include the latter method

user92578

Just the first one, as I yet have no need for finding the intersection point

William 'MindWorX' Mariager

Fair enough.

Intersection point is nice for stuff like lasers though. ;)

user92578

Sure

William 'MindWorX' Mariager

I used it for line of sight lines.

user92578

11:30

That's a good use that I'll probably end up using too

user92578

uh there's a bug in the circle vs box collision code

user92578

I added a derpy force that will throw the character from a saw blade

William 'MindWorX' Mariager

lol :P

user92578

hmm not sure what to do next

user92578

everything seems so big

William 'MindWorX' Mariager

11:39

Do you have a list?

user92578

yeah

William 'MindWorX' Mariager

Lists are important. I have a general goal for HDN and then a milestone with the things I consider important for a beta version

user92578

This one is not very well organized in terms of priority, it's just stuff that I'd like to add and stuff that really really has to be added

William 'MindWorX' Mariager

The beta milestone has a lot of trivial things, like game state for menu/game transition, menu for starting, settings, etc.

I would definitely sort things in beta and release, and then keep the beta list short with only essentials needed to call it a game.

user92578

I've been thinking about doing this: gamasutra.com/blogs/YoannPignole/20150427/241995/…

user92578

11:44

But I'm not sure if I can follow that one as my collisions aren't tile based

William 'MindWorX' Mariager

You should be able to

Since your game is static, you could just manually add the points. :)

user92578

Nah that's too much work I think

William 'MindWorX' Mariager

I'd just add a few different pathing AI's.

Ones that don't go over the edge and ones that does.

user92578

But those would still require a path-map of somesorts right?

William 'MindWorX' Mariager

Not really.

Since you already have ledge detection, they would just change direction when one of the rays didn't hit ground.

user92578

11:54

ah right

William 'MindWorX' Mariager

Yeah

It's easy to create some interesting pathing AI's without actual pathfinding.

Ali.S

@William'MindWorX'Mariager what kind of paths? in what kinds of mazes?

William 'MindWorX' Mariager

@Ali.S This is just a platformer.

So basically look at Mario for inspiration and extend upon that :P

Ali.S

platformers usually don't have any paths to be found :|

Pip

not true

the shells, all of the enemies

bosses

etc

William 'MindWorX' Mariager

12:04

@Ali.S Terraria is a good example of a platformer that needs better pathfinding. :P

Enemies just wander aimlessly.

user92578

This a great blog that I just discovered: joostdevblog.blogspot.fi

Jon

guize

channel9.msdn.com/Events/Build/2015/2-631

This is awesome.

Blue Bug

it seems Unity slows DOWN if you try to render 3d objects with orthogonal camera model.

weird..

Jon

doesn't sound right

Blue Bug

I have really shitty cpu. When I add 3d objects into 2d camera view, my fps drops from 60 to 40~50

Jon

13:04

that sucks

Blue Bug

no.. it.s ok. It forces me to make things more efficient.

Jon

heh, fair enough

Blue Bug

though... I would prefer a new computer lol

Ali.S

13:26

@William'MindWorX'Mariager terraria is not the first platformer game that comes to my mind...

when I here platformer, I usually thing of actually some platforms with some enemies that wander aimlessly (like mario)

Pip

@BlueBug lol

@Ali.S technically they aren't actually aimless :)

Ali.S

they usually don't care about you, that's aimless enough for me :D

Pip

@BlueBug liking the new patch?

Blue Bug

@Pip 6.84? heck yeah. Luv all these new support items.

Pip

:D

My favorite items have to be Octarine and Silver Edge

Blue Bug

13:39

mine is the invisible cape!

(saved allies with that shiny dust countless times, it's sorta like oracle's ult)

Pip

The glimmer cape?

Oh man it is sooo amazing for Witch Doctor

he can use it while channeling his ult

perfection

Blue Bug

it got nurfed though...

Pip

oh already

Blue Bug

150 mana cost RIT glimmer cape.

Pip

link to patch notes?

Blue Bug

13:43

it just got patched a few hours ago

Pip

ah I see

along with the new Immortal treasures from the Compendium?

Ali.S

I love ocrtarine

Blue Bug

#Pip dota2.gamepedia.com/Glimmer_Cape 130 mana

Pip

it's great

Ali.S

the rest well, they are good to be there

Pip

13:44

thanks

Hjorthenify

"Glimmer cape"
How original!

Blue Bug

how about some mangos? is anyone having delicious fruits?

Ali.S

also new refresher receipt is nice..

mangos are great, but not for every hero... Is still have to find the suitable hero to use them

man, I want compendium

Blue Bug

I am a bit tentative with new receipt. Refresher Orb costs 375 mana to ~~cost~~ cast. Though regenartion seems to be fitting theme but it needs some mana boost as part of receipt( I think )

Ali.S

it didn't boost your mana that much before either

Pip

13:48

@Ali.S Techies!!!!

2 mangos and a bunch of clarities

omw it is amazing

Ali.S

doesn't soul ring fit him better?

Blue Bug

true...

Pip

You can't buy soul ring right away

Ali.S

you almost can

Pip

yeah but there is no point then

Ali.S

13:49

you just have to wait for a mere 2 minutes before you can buy soul ring

Pip

The biggest part about Techies is getting to lane and placing a shit ton of mines to get first blood (so you need a TON of mana regen right away)

Blue Bug

why not soulring + mangos

Ali.S

even if you don't get FB

and you buy 4 clarities

Blue Bug

@Pip That's a greedy and risky build.

Pip

That's what Techies is for

Blue Bug

13:52

3 clarities == 1 mango, 3 Clar = 170 * 3 = 510, 1 Mango = 150 mana

Pip

> .NET Core has reached a major cross-platform milestone with a preview of the .NET Core runtime distribution available for Linux and Mac.

@Jon !!!!!!!!!!!!!!!!!!!!!!!!

@BlueBug Mangos are instant. You get both though

Ali.S

@Pip techies mines have very long cd

Blue Bug

true. hmmmm 3 clarity == 45 *3 = 135 seconds, you save about 135 seconds but lose about 360 mana

Ali.S

so then being instant almost doesn't benefit at all

each mine at level 1 has about 20s cd

you can land the first mine, and use your first clarity right away

Pip

Yeah

but after the second mine you waste time waiting for mana

Pretty sure the timing works out right there

so you use a mango as well

Ali.S

13:56

well, with techies mana pool you can put 3 mines right away, without any mana regen

with clarity you can put 4-5 (I don't really remember this one) back to back

Pip

Yep

Ali.S

but then you've got to wait...

note that with mangos you can put one extra mine per mango (150gp)

Pip

With mangos you can put 7-8 (maybe 9 if you work the math a bit, I think)

would take a lot of gold though

you could use a clarity while using mangos

I might work the math later

Blue Bug

u have a mango hype man. Mango is alllllright.

Pip

lol

@Jon oh man I just had an idea. M$ is releasing the .NET Core runtime for Linux, right? I bet we could port it to Android :D

Would take some work

We would probably have to write some Java to boot the runtime

Ali.S

14:28

ok, now there's only $3.84 remaining to get my compendium ...

$3.54...

just put most of my items on sale....

Pip

lol why would you do that

it's like 10 bucks

Hjorthenify

Compendium?

Pip

Thing for Dota

basically gives you ingame shit and the majority of the money Valve makes from it goes towards the prize pool at The International.

Hjorthenify

14:54

Ah nice.

Blue Bug

as I am playing the game, I am often seeing many people who have paid over 100 bucks for it. (you can pay more than 10$ )

you get unique cool particle effects for your character in game for over 100 bucks. The scary thing is I too want to get them and seriously considering spending 100 bucks.

Pip

lol

Blue Bug

I am too deep into the virtual hats and cloth at this moment. OTL

Pip

I was considering it until I realized it wasn't worth

Blue Bug

hey

Hjorthenify

15:01

Like CS:GO knives which costs 500$?

Blue Bug

you get THE GOLDEDN BLACK HOLE

Pip

lol

Hjorthenify

A guy at my dorm got a knife in CS:GO he sold it for a month's worth of rent

Pip

nice

Blue Bug

@Hjorthenify Something like that... Valve is so good with making virtual stuff worth so much a lot more.

Hjorthenify

15:02

Yeah :P

Pip

15:30

@Jon so, I have a solution for compiling the CoreCLR I THINK

kandroid.org/ndk/docs/STANDALONE-TOOLCHAIN.html

I am going to try to get this started, but it may require linux for now since I don't understand how some of the CoreCLR Windows stuff works

we shall see

Hjorthenify

15:58

@Pip What are you trying to achieve?

Pip

Monogame on Android

Need a C# runtime for that, which the CoreCLR is
