now there is really slow movement towards target follow

mean main player goes out of the screen

Jon

goes out of the screen when you move?

Siddharth

mean player is already moving to right side

Jon

adjust the lerp value -- to something higher

Siddharth

we have to follow it

okay

trying

Jon

player on right side?

change your offset direction

Siddharth

12:04

I have set value to 0.5

but no change in output

I am mentioning code that i have used

recent code link

please sir check it

Jon

Check what?

Siddharth

modified script code

pastebin.com/mVPy5H9h

in pastebin

found it or not?

Jon

That is just stupid man

targetInitialPos is vector3.zero

Siddharth

no

because I have not set my player at zero position

at start up

so it definitely got different valye

Jon

ok, well you know what you are doing then

Siddharth

12:10

so I added it as offset that you have suggested

if I try something else then no change in output

Jon

put a breakpoint on that line

Vector3 adjustedTarget = camera.WorldToViewportPoint (target.position + targetInitialPos);

and tell me what targetInitialPos is

Siddharth

else part gives you information about ath

that

Jon

oh ok

your logic is flawed. do it

does it even hit the breakpoint?

sup pip

Hjorthenify

@Jon ! I DID IT!

i.imgur.com/fSudRr1.gifv

Jon

yay

wow that looks good

Siddharth

12:15

mean when I found target

Kevin van der Velden

@Hjorthenify got the animation working?

Looks nice

Siddharth

and store its position

Pip

@Jon morning

Jon

@Siddharth did you put that breakpoint?

Siddharth

that I used as offset purpose

no not at all

Jon

12:15

well then..

you don't believe me?

Kevin van der Velden

Please don't be like... who was it @Tyyppi_77 or @Pip and not be using a proper debugging

Hjorthenify

@KevinvanderVelden Not quite, but I made the background move forever :P

Kevin van der Velden

@Hjorthenify aah

Hjorthenify

The anim still needs some tweaking

Siddharth

totally believe to your suggestions

I am just trying to that

user92578

12:16

@KevinvanderVelden Could've been me print()ing in Python

Jon

Do you know how to use breakpoints?

Pip

lol

Kevin van der Velden

@Tyyppi_77 probably

Dunno

Pip

Breakpoints are nice

Kevin van der Velden

No wait, it was C++

user92578

12:16

yup

Siddharth

Debug.BreakPoiint()

right?

Jon

no

user92578

well I've used those quite a lot now

Siddharth

then what?

user92578

but could still be me :)

user92578

12:17

@Siddharth F9

Jon

ever see one of these red dots?

it interrupts the flow of your logic

user92578

interesting setup

Hjorthenify

-.-

Siddharth

yes that I know

Jon

12:18

ok, so put a breakpoint on that line

run it and connect it to unity

Hjorthenify

http://pasteboard.co/2eUY3sFy.png
THAT'S how the setup looks... hopefully

user92578

yup, looks cool

Jon

yeah man

user92578

needs awesome dynamic shadows tough

Hjorthenify

Oh yes.

Siddharth

12:19

then what?

Jon

@Hjorthenify what are your plans with this?

Siddharth

what I have to find?

I have to just go for tea

come soon again

Hjorthenify

@Jon Survival arena games where you scavenge metals from the robots you slaughter to build up a defence

Jon

i want you to tell me what the var is

Hjorthenify

game*

Siddharth

12:20

first I implement whatever get from you guys

Jon

how many ppl working on it?

Siddharth

thanks for help

Jon

np

Hjorthenify

Working on mine?

Jon

yeah

Hjorthenify

12:21

Just me

Jon

wanna ditch your battle arena idea, and collab on something else?

Hjorthenify

Like?

Pip

hahaha

Hjorthenify

The arena is more so that I can test stuff. I might turn it into a RPG later

Jon

twin shooter

Hjorthenify

12:23

Yes?

Jon

yeah, you can do the art

and i'll write the code

lol

Hjorthenify

Nah I'm good :P

Jon

been working on this

Hjorthenify

Yeah the pathfinding

Jon

yeah, working on group behaviors now

I have a fun idea for a game, heh

Hjorthenify

12:25

Yeah

Jon

I like the idea of HUGE amounts of mobs

Hjorthenify

Sorta like L4D amounts?

Jon

yeah

Hjorthenify

Nice

Jon

or like gauntlet original

Hjorthenify

12:27

O_o

Leggy7

hello guys, is there any Unity expert here? I posted a question with what in my beginner point of view is a strange behavior

0

Q: GameObject scope over RPC call

Debugging my code I faced some unexpected behavior. I called an RPC using uLink.NetworkView on the server passing some parameter including a GameObject tagged as Player. Inside that RPC I make a call to GameObject.FindObjectsWithTag("Player") What I refer to by saying "unexpected" is that that...

Hjorthenify

Doesn't unity come with built-in pathfinding?

Jon

Yes.

Leggy7

I think you need unity pro to use the aaron pathfinding asset

Jon

However, the Pathing tool only works in 3d

Pip

12:28

mhm

Jon

unity 5 unlocked it @Leggy7

Hjorthenify

Aw man

Leggy7

oh!

Pip

2D is a bitch, I wrote my own

Leggy7

cool

Jon

12:29

aye.

Pip

@Hjorthenify you can have the source if you want

Jon

Mine is way more advanced than pips

Hjorthenify

It is tilebased?

Jon

you want the source?

Pip

Truetrue

@Hjorthenify eyp

Hjorthenify

12:29

://

Jon

you can't handle the source

Pip

lol

Hjorthenify

Nah I'll just improve the source and you're afraid of it

Pip

Alright, time to make some path sprites instead of just setting the color of the tiles

Jon

@Pip make sure to bitmask those

otherwise it will just look weird.

or just use a LineRenderer

Thick on one end, and 1 pixel on the other, make it look like an arrow

demonstrate direction

Pip

12:32

Yeah, definitely doing some bitmasking. That's what's been intended since the beginning :D

Jon

bitmask it man

lol, just trying to annoy you with the bitmask stuff

Hjorthenify

How would bitmask help here?

Pip

Actually intending to do it XD

Jon

angryfishstudios.com/2011/04/adventures-in-bitmasking

4

a couple got snagged

still manage to get out of it though

Pip

@Jon Yes Jon :P

Jon

12:42

it is fun to play around with, heh

Pip

I need to find some way to do mountains.... the cellular automata thing I did will work fine for resources but I want mountain chains instead of.... mountain blobs :P

Was thinking about bilinear interpolation, and just setting each tile's height based on some random nodes, then ones that exceed the limit would be mountains

Jon

create a heightmap

Pip

Something like this

Jon

that could work

Pip

Yeah, I want to see how it turns out before I scrap it

Hjorthenify

12:47

I have no idea what I wanna do next.. Weapons, AI, objects, what do you think I should do?

Jon

AI

you are gonna need a pathfinder if you plan on doing ai

Hjorthenify

True

Jon

might as well get Pip's

Hjorthenify

Yeah I thiink I'll do pathfinding

Well problem is that my map isn't grid based

And I need to take deployable walls and stuff into account

Jon

welp, that is where my pathfinder comes in handy

i can help you make it if you want

Hjorthenify

12:51

That'd be great :D

Jon

It is an incredibly simple concept

Hjorthenify

Yes?

Jon

1. Define an area for your map.
2. Raycast down, at predefined intervals, in a grid like fashion.
3. Create a game map based on the collisions.

Then, I found out that , some of the connections could be bad if the walls were thin enough.. so

4. Raycast between connection points, removing bad ones.

Then you can run the game map into a a* pathfinder

Hjorthenify

:o

So that's what those points are in your game?

Jon

the points are for debugging, but yeah

notice they are either green or red

Then the red lines show that the connection was removed

you do this calc when you load the level

It is really fast from my testing

Hjorthenify

12:55

So just test it once?

Jon

as long as your world is not huge

yeah, run pre-calcs..

I have a seperate collision system for dynamic entities

Hjorthenify

For the points to remove?

Jon

that map is just for pathfinding in the world.

Yeah.. for the points to be marked as a collision

so your pathfinder doesn't try to make you walk through a wall

Hjorthenify

Yes

Jon

I guess it is pretty advanced

but the concept is pretty simple

Hjorthenify

12:58

Its smart.

Yeah you said that you calculate the red lines when you load the level, right?

Jon

Yep, it has its limits though -- wouldn't work well if you had to constantly update the level data

yeah

Hjorthenify

but what's the interval for then?

Jon

If you had to open, close a door, you could alter that data manually for example.

instead of re-raycasting

the interval?

Hjorthenify

1. Define an area for your map.
2. Raycast down, at predefined intervals, in a grid like fashion.

oh

Jon

oh, the distance between nodes

Hjorthenify

13:00

Thats a distance interva

Not a time xD

Jon

in my case I do x+=1 y+=1

so that my x,y coords work well with a map

well.. I do y-=1 and invert it actually

Hjorthenify

Ah

Jon

public void Initialize(float x, float y, Vector2 position)
{
    X = (int)x;
    Y = (int)y;

    Position = position;

    RaycastHit2D hit = Physics2D.Raycast(position, new Vector2(0, 0));
    if (hit.collider != null && hit.collider.tag == "Wall")
        Collidable = true;
}

Hjorthenify

How do you store the grid?

Jon

public Dot[,] Dots;

Hjorthenify

13:02

Like where's the script stored and how do you access the data?

Jon

I called them dots.

shuld of called them Nodes

Hjorthenify

I'll code them nodes

Jon

oh, the Grid is generated with an empty gameobject, called Grid with a Grid script attached

Hjorthenify

So if I added an object to the grid, then I would just have to figure out which dots that are at its location, right?

And you access it how? I don't know how to call functions from other scripts, yet.

Jon

Eventually, that gameobject will be removed, and the Grid will be called from some Game manager

The grid doesn't need to be extended from MonoBehavior

Hjorthenify

13:04

Right

But still.. How do I access stuff from the script?

Jon

You can access it just like you would usually

Hjorthenify

I'm new to unity :P

Jon

Lets say you have a gameobject, and you want to access the script

go.Getcomponent<ScriptName>()

Hjorthenify

So just gameObject.Dots

Jon

this will return the object reference to that script component

Hjorthenify

13:05

Ahh

Jon

but for your grid though, you could just have a Grid grid; object in some other script component

and just use it from there as well

In my case right now, i have a Grid script component on a gameobject

and it loads up a Dot[,] array which is the game map

each dot does a raycast -- then checks its 8 neighboring connections

When you get to your Pathfinder -- you check your 8 neighbors, but opt out of the ones that were flagged as being removed

Hjorthenify

I see

Jon

super easy

lol

Hjorthenify

So each dots just raycasts its 8 neighbours?

Jon

raycasts down to see if it is on a wall

pass 1

check neighbors, if red or green

pass2

you need to do it in two stages

Hjorthenify

13:10

I see

Jon

if a neighbor is RED, then you can't travel to it

Hjorthenify

But wouldn't a raycast to one of its neighbours tell if its in a wall?

Jon

yes

you need to raycast in the 8 directions

or 4 if you don't want diagonals

Hjorthenify

... so what's the point of casting down first?

Joe

@Jon the company is called mediocre industries ... i cant imagine they worry much about how performant their javascript is :D

Jon

13:12

if your walls are super tiny and manage to fit between the 8 raycasts, then you reached a limitation of this design

hmmm

Hjorthenify

I see..

Jon

i have to thinmk about it, but you might be right

might not have to cast down

Hjorthenify

:D

I knew I could help...

Jon

because I originally cast down and figured it was going to be ok

and added the connections thing later

the connections thing should be all that I need

Hjorthenify

I'm not sure if I even need to take size into account

Because my walls is going to be about the same size as the units

SpartanDonut

13:14

Today is going to be a fabulous day!!!! .................. April Fools! -_-

Joe

so Spartan your coming to the Unity Roadshow in Philly tommorow right?

Hjorthenify

My boss called me and told me I was fired...

That bitch

Joe

^ LOL, you got owned

also sue the hell out of that company, thats nothing to joke about

Hjorthenify

Maybe in America :P

But Im great friends with my boss so I knew he was joking :P

Joe

yea your right... my american brain went right to lawsuit

Pip

13:16

lol

Hjorthenify

Haha yeah.. He actually wanted me to come to work today because they had some UPS's which needed to be moved, but hell no.

Jon

@Hjorthenify yep you are right, the original raycast is not needed

however

Hjorthenify

:D

Jon

it greatly improves the pathing

because a connection doesn't define the node

so you can't assume a node is valid

but it could be

Hjorthenify

Uhmm. what?

Jon

13:18

anyways, it shrank the available moves

oh wait n/m

it has no effect

no it does, i didn't save my change

lol

Hjorthenify

...

So it does have a purpose?

Jon

I'm gonna have to revise my code

it does

but it probably shouldn't

Hjorthenify

Yeah

Jon

I can't explain why the behavior changes when I remove that raycast

Hjorthenify

:\

It shouldn't

user92578

13:28

Yay almost got everything back

Jon

yeah I know ,trust me this is annoying me

user92578

still need to make wall particles bounce back a little

Jon

it works fine

its just that it takes weird routes sometimes

it will randomly go up when it should remain down

but if I add that raycast down, it doesn't do that

Hjorthenify

Erhmm.. What? xD

What do you raycast down to btw?

Just a random distance?

user92578

I have not cast a single ray in my whole life

Kevin van der Velden

13:36

@Tyyppi_77 aaah =[

You should write a raytracer, those are fun to make

Hjorthenify

@Jon Would it be possible to make your setup account for width?

Jon

width of what?

Hjorthenify

Well size of the object following the path

Jon

oh

no

you would have to adjust the sample size

ie. the distance between nodes

as long as the distance between nodes is smaller than your object, you should be ok

errr.. larger

Hjorthenify

But what if the wall is halfway between the two nodes?

Jon

13:49

Mine is set to the same size as my circle radius

Hjorthenify

Yeah?

Jon

if it is the same size it seems to just work

Hjorthenify

Hmm

but

your walls are drwn between the nodes, right?

Jon

walls are drawn first

walls are positioned anywhere.. then the nodes drop down and create a map based on where the walls are

you need to tweak it for sure

works for me

Hjorthenify

Yeah..

Jon

13:54

ah.. so I found a bug

Hjorthenify

Yes?

Jon

this path says it is valid when the raycast down is turned off..

not sure why as it is red

but i'm on the right track now

Hjorthenify

Ahyes

Jon

found it.

was a directional error

vertical axis was reversed.

ahhhh

much better -- now that raycast is not required for sure :D

Hjorthenify

Yay!

Is there a GetObjectInRange(int range, int filter) function i nUnity?
