stupid unity with its lowercase public variables and K&R braces

SpartanDonut

use VS

solves the bracing problem

Icy Defiance

not for the initial template it doesn't

gotta fix it for every new script

so much work :'(

SpartanDonut

Like... 3 key presses? :P

4...

Lokkij

Ctrl-K, Ctrl-D. Done.

SpartanDonut

3 if you don't lift your finger off Ctrl

Icy Defiance

23:10

ooh, I forgot about that one

OMGtechy

@IcyDefiance the bracing really burns.

Icy Defiance

also, stringly typed things

Input.GetAxis("Vertical");

Lokkij

Definitely not perfect, but I'm getting closer...

SpartanDonut

@IcyDefiance the reasoning there is customizability. There are better ways they could handle it but take a look at Edit -> Project Settings -> Input

You can rename "Vertical" to whatever makes sense for you

And bind whatever keys make sense for you

I've not investigated better input managers for Unity but the basic functionality there is pretty nice with no effort basically

Icy Defiance

okay that does make sense

being stringly typed is more of an unfortunate side effect, I guess

SpartanDonut

23:20

Pretty much

OMGtechy

yeah

you get used to it

SpartanDonut

I'd have liked to have seen some interface where you could bind scripts to the input manager, much like linking objects together with monobehaviors but like I said, out of the box with no effort what they've offered is pretty nice

OMGtechy

Just don't go making 30 calls to GameObject.Find("Foo") per update aha

SpartanDonut

or Debug.Log() 500 times per update :P

OMGtechy

ahahah

@SpartanDonut what do you mean about binding scripts? You can do that

For one of my jobs, I made a game state machine thingy that just took scripts in the inspector

SpartanDonut

23:22

For input manager specifically

Instead of just the GUI where I create a command "Jump" and assign buttons to it I'd like to be able to create a more flexible coded system

OMGtechy

One thing I wish Unity would make work out of the box is containers of interfaces

SpartanDonut

Though I think you can access and update those values from scripts...

but yeah

Almo

@AttackingHobo just showed it to my pal who loves hardcore games. he said it was great, and "why can't I think of this simple shit?"

AttackingHobo

:D

OMGtechy

@Almo What's better is I've already played a game exactly the same as that, but I never thought to put it in a browser...

SpartanDonut

23:24

The only other game I played like that was one of his initial prototypes from like a year or so ago

But I don't play much

OMGtechy

Really? They're really common over here. You go to the cinema and there's usually an arcade style machine for it.

RhysW

exactly what i first thought of

SpartanDonut

@OMGtechy oh ya. totally forgot about that

Ok so other than that arcade machine I've not seen it :P

OMGtechy

@SpartanDonut with this new GUI system, do I still have to create a script to load the next scene? There's this event thing I feel like I should be using...

SpartanDonut

uhhh

I think so?

I don't see how loading a scene has to do with gui so I've not looked into it

The event system is more for input events

mouse over, mouse click, etc.

OMGtechy

23:29

Yeah, but you have OnClick etc

that calls a function right?

So what if I wanted it to call Application.LoadLevel?

Just seems silly if they haven't added that

SpartanDonut

I really have no clue what you're saying

OMGtechy

oo it seems I'm not the only person that asked this

answers.unity3d.com/questions/780359/button-on-click.html

short answer is no

SpartanDonut

Ah

You want to call just a single function on click is what you're saying

why didn't you say so? :P

OMGtechy

2 mins ago, by OMGtechy

So what if I wanted it to call Application.LoadLevel?

:P

Lokkij

@OMGtechy In my testing I used this function to add callbacks to OnClick from scripts:

public static void AddCallback(string buttonName, Action callback)
{
    FindUIElement<Button>(buttonName).onClick.AddListener(delegate { callback(); });
}

OMGtechy

23:32

Whaaa

SpartanDonut

@Lokkij requires a script. He wants to be lazy and not use a script

OMGtechy

^

Lokkij

Oh.

SpartanDonut

Which is tough titties

OMGtechy

Guess I'll have to just make a script :(

Lokkij

23:32

I misinterpreted your question then.

SpartanDonut

You can go hang out with the folks who want C# functions outside of classes

OMGtechy

Thanks anyway @Lokkij :)

RhysW

@SpartanDonut ew

SpartanDonut

@Lokkij that's because despite what he thinks he wasn't being clear lol

OMGtechy

@SpartanDonut I also want this

I think static classes should be outright banned

stupid things

SpartanDonut

23:33

The older I've gotten the more stubborn my brain has become to making assumptions about pronouns. If it's not obvious my brain gives up and freaks out

OMGtechy

ahaha

SpartanDonut

Static classes are great

OMGtechy

They're namespaces with a contructor

and singletons

SpartanDonut

If you choose to use them like that sure

OMGtechy

the singleton thing makes sense, but the namespaces with a constructor doesn't

it's called a class, but it isn't a class

that's why I don't like it

Icy Defiance

23:34

6 lines of code written in unity, and I've already hit my first "wtf this makes no sense" moment

void Update()
{
    thrust = ThrustPower * Input.GetAxis("Vertical");
    rotation = RotationSpeed * Input.GetAxis("Horizontal");
}

right there, rotation works fine, but thrust is always 0

OMGtechy

@IcyDefiance DELTA TIMEEE

oops

Lokkij

@IcyDefiance Because thrust is not on a MonoBehaviour.

Icy Defiance

it is though?

Lokkij

Maybe something like rigidBody.thrust?

Icy Defiance

oh, it's a private variable I made

SpartanDonut

23:36

I assume you've confirmed ThrustPower is not zero and that Input.GetAxis("Vertical"); is zero

Icy Defiance

ThrustPower is 5

so yes, 5 * Input.GetAxis("Vertical") is 0 when I'm holding down W

OMGtechy

Programming in general is just a series of WTF moments stringed together in a fashion that makes you look like you know what you're doing. Unity doesn't do it any different.

Icy Defiance

even more strange, it worked until 2 minutes ago, and I didn't change that line

Almo

@OMGtechy :D

OMGtechy

Shouldn't you be using add force? @IcyDefiance

SpartanDonut

23:37

Did you accidentally break something in the input manager?

Icy Defiance

@OMGtechy I do that afterward

SpartanDonut

@OMGtechy he's trying to first calculate how much force to add

OMGtechy

oh ok

Icy Defiance

@SpartanDonut checked that. it still looks right.

RhysW

w moves you vertically?

SpartanDonut

23:37

Alt Positive Button: w

Icy Defiance

yep

SpartanDonut

Does s work?

Icy Defiance

nope

SpartanDonut

Did you accidentally (or intentionally) make a typo in the name "vertical"

otherwise pastebin your class

Lokkij

Did you make sure to capitalize the V in "Vertical"

Icy Defiance

23:39

the code I gave is copy/pasted from my script

and I just checked it against the name in the input manager. it's right.

SpartanDonut

@IcyDefiance yeah but I asked for the whole class not the isolated snippet where you believe the problem lives

Icy Defiance

sure

SpartanDonut

I want to trust you but I don't trust anyone who says "everything else is right" when helping debug code

Icy Defiance

pastebin.com/35mjwN2c

SpartanDonut

On your object in the inspector, is ThrustPower 5 still?

Lokkij

23:41

^

Icy Defiance

yep

rotationspeed is 300 in the inspector instead of 5

setting thrustpower to 300 in the inspector doesn't make a difference

also, not sure why I'm not processing input in fixedupdate... but I figured I'd just copy the tutorial and worry about that kind of thing later

SpartanDonut

So is the problem the ship isn't moving or have you checked the values of the variables?

Icy Defiance

the private variable thrust is being set to 0, even when I have W or S held down

rotation doesn't have that problem. it's working fine.

SpartanDonut

so Debug.Log(thrust) prints 0

Icy Defiance

I actually used a breakpoint, but let me try that too

SpartanDonut

23:45

no thats fine

OMGtechy

I have a (very) basic menu going in now

SpartanDonut

Just triple checking we don't have a physics problem

Icy Defiance

well then, debug log does print out numbers other than 0

SpartanDonut

oh damn

OMGtechy

stupid debugger

gdb once told me it was calling a constructor 3 times then jumping into the middle of a function

it was no

not*

SpartanDonut

23:47

Sounds like a bad build problem

OMGtechy

nope

SpartanDonut

Or code that doesn't match the running assembly

I believe you

Icy Defiance

if I add a conditional breakpoint on the same line as debug.log, and set the condition to "thrust != 0", it never breaks, even though it's logging 5

SpartanDonut

Just what I'd suspect if it happened in VS

OMGtechy

na it was netbeans

but still

the general consensus was don't trust the debugger

I had an SO question about it, let me find it...

SpartanDonut

23:48

So it sounds like we have a physics problem and a bad debugger problem

Monodevelop?

Icy Defiance

nah, unityvs

SpartanDonut

hmm

Did you import the VS package to the unity project?

OMGtechy

^

Lokkij

I was going to suggest GetAxisRaw but this is really weird.

Icy Defiance

I did

SpartanDonut

23:49

Weird

Q: Strange looping at end of function body call C++

I am writing a game program in C++ and have encountered an odd problem that seems to be unique to this function. When this function is called, it executes just as expected all the way through to the return statement. However, upon executing the return statement, the code 'jumps' up two lines to ...

there it is

SpartanDonut

Hey I reproduced Icy's issue. What fun

OMGtechy

what is this madness

SpartanDonut

I blame fixed update

OMGtechy

I generally steer clear of it, but since you'll be adding force I guess you've gotta use it

Icy Defiance

23:54

moving those 2 lines to update doesn't change anything

Lokkij

I didn't know about FixedUpdate for a while and did physics stuff in Update and it worked just fine.

SpartanDonut

Yeah Update didn't fix it for me too

OMGtechy

is the logger truncating the floating point?

try printing if it's non zero as a bool

ElfSlice

here's an animation process gif for people who like that stuff :) http://i.imgur.com/fmVbg4e.gif

SpartanDonut

Adding a watch for Input.GetAxis("Vertical") fails

how to I view the exception... hmm

Jon

23:58

holy shit that is a lot of work

OMGtechy

@SpartanDonut did you try the bool thing?

SpartanDonut

no but I think I found the problem

OMGtechy

oh cool

Icy Defiance

@OMGtechy I did. it works as expected.

OMGtechy

hmm

Icy Defiance

23:59

it's not colliding with anything either.
