Hey,

the idea to implement Snake in Metin2 came from MrSIB

I think it's a cool idea and that's why I implemented it.

Preview

Control

w,a,s,d to control the snake

spacebar = pause

Settings

You can set in the script if you are allowed to go through the wall or not and change the size of the drawn boxes or the playing field.

Execute:

e.g. in the game.py above to the imports:

"import snakeGame"

After logging into the game you will see the window.

Settings

DEBUG = False ## Enable debug

BOX_SIZE = 10 ## You can change the size of the drawn boxes as you like. I found 10 quite good.
## width and height are your playfield sizes. I found 200 quite good. But if you set the BOX_SIZE to 1 it is too big.
GAME_BOARD_WIDTH = 200
GAME_BOARD_HEIGHT = 200

## keyboard bindings
KEY_RIGHT = app.DIK_D
KEY_LEFT = app.DIK_A
KEY_UP = app.DIK_W
KEY_DOWN = app.DIK_S
KEY_PAUSE = app.DIK_SPACE

INCREASE_SPEED_AFTER_EAT_COUNT = 3 ## after the snake reaches the length 3, 6, 9, ... the speed is increased.
SNAKE_START_COORDS = [[2,1],[1,1],[0,1]] ## head, tail, tail => Ooooo
SNAKE_START_DIRECTION = KEY_RIGHT ## the starting direction of the snake
START_SPEED = 1.2 ## 1.2 = slow (paint snake every 1.2s)
MAX_SPEED = 0.5 ## 0 = fast
BORDER_DEAD = True ## if the border is hit then dead (true) or pass through (false)

## https://doc.instantreality.org/tools/color_calculator/
SNAKE_COLOR = grp.GenerateColor(0.027, 0.490, 0.078, 1.0)
SNAKE_HEAD_COLOR = grp.GenerateColor(0.176, 0.725, 0.235, 1.0)
SNAKE_DEAD_COLOR = grp.GenerateColor(0.9, 0, 0, 1.0)
FOOD_COLOR = grp.GenerateColor(0.9, 0.5, 0, 1.0)
BORDER_COLOR = grp.GenerateColor(1, 1, 1, 1.0)

Have fun!

Hey,

due to recent events, I wanted to publish a bug, which was available in my itemshop a few years ago.

In many pub systems written with Lua, it is still present and some people like to take advantage of it.

If we continue the example with the itemshop, it was possible to "buy" items for free.

For example, instead of a number, the client sends the value "NaN" (Not a Number) for the number of items to be bought.

In the quest tonumber() is now executed and "NaN" remains "NaN".

cmd = "NaN" --(sends "NaN" instead of a number)
amount = tonumber(cmd) -- now contains NaN

If a comparison now is made, the result is always false:

if amount > 200 then print'The maximum amount is 200.' return end -- FALSE
if amount < 1 then print'The minimum amount is 1.' return end -- FALSE

That is not such a big problem at first.

But if you do a calculation and then compare if the coins are enough, then we have a problem:

cmd = "NaN" --(sends "NaN" instead of a number)
amount = tonumber(cmd) -- now contains NaN
mycoins = 0 -- The number of coins from the Coins column of the account table
itemPrice = 1000 -- Price of the item in the item store
realPrice = itemPrice*amount -- 1000 * NaN => NaN
if mycoins < realPrice then print 'Unfortunately you do not have enough coins.' return end -- FALSE (0 < NaN)
-- Not enough Coins, but it goes on, because the comparison was false.
-- Give item.
-- Item was bought with 0 Coins.

Here is a link to it:

http://lua-users.org/wiki/InfAndNanComparisons

A script for testing (https://repl.it/ under Lua):

-- cmd is the value sent by the client as example a number of items you want to buy. If you now calculate with this value and send instead of a number NaN, inf, -inf, ...
cmd = "200"
--cmd = "NaN" -- remove comment for testing (sends "NaN" instead of a number)
amount = tonumber(cmd)
-- mycoins is the number of coins, which are in the Coins column of the account table
mycoins = 1000
-- mycoins = 0 -- remove comment for testing (sets existing coins to 0)
itemPrice = 100
 
if amount > 200 then print 'The maximum amount is 200.' return end
if amount < 1 then print 'The minimum amount is 1.' return end
 
realPrice = itemPrice*amount
 
if mycoins < realPrice then print 'Unfortunately you do not have enough coins.' return end
 
newCoins = mycoins-realPrice
 
print('set new coins in db '..newCoins)
print 'give item

How it can be fixed, for example:

function IsFinite(num)
    return not (num ~= num or tostring(num) == "inf" or tostring(num) == "-inf" )
end

-- Example call
amount = tonumber("123")
if not IsFinite(amount) then return end -- Everything ok
amount = tonumber("NaN")
if not IsFinite(amount) then return end -- triggers return

Hello, how are you? do you disagree? please let me know.

Thanks for asking. I'm fine.

Maybe u forgot the real question?

#Small changes

When holding CTRL (can be changed) the cursor changes and text can be translated instantly.

In addition, already translated texts are now stored for faster translation.

Is there a better alternative with api?

Sure. Deepl. But I have not found any way to use it without paying 0.01€ per 500 character.

There is already an identical system on the server rop2.global ...

Yes this is my system. xD

It's the first Version. I am currently updating the translator with some new functions.

Hey,

I am currently working on an ingame translator (Python & c++) for Metin2.

It uses the Google Translator.

You only have to press the "Translate Button" at the bottom of the taskbar (the cursor changes then) and any text can be translated directly.

If you want to select more text at once, then you have to hold shift.
If the "Instant Translate" checkbox is activated, the text will be translated on sending (for chat and whisper).

A preview of the current state:

Do you find the whole thing useful at all and would you want to use it?

Do you have any ideas?

Sexy, i hope that code is also sexy ;3

The code has been kept simple so that it can be easily understood. You can always optimize everything.

Great job, this is a very handy reference. Could you use github gists/repo instead of mega downloads? Thanks

Yeah, I've been thinking about that, too, because things are getting messy. As soon as I find the time.

Introduction

Hey,

since I'm often asked if I can make an example for this or that in Python, I just post some of these examples in this thread from time to time.

Usually they just end up in my trash (that's why the collection is small for now) but maybe it will help some of you to learn something.

You are also welcome to post examples here and I will add them to the startpost.

You have a wish for a certain example?

Then write it in here.

PS:

These examples are designed very simple, so that they can be understood.

Examples

ui.ComoBox()

ui.ScrollBar() with text

ui.AniImageBox() as loading bar

ui.ListBox()

ui.ToggleButton()

ui.RadioButtonGroup()

ui.DragButton()

ui.Bar(), ui.Box(), ui.Line()

ui.Gauge(), ui.SliderBar()

ui.TextLine(), ui.EditLine()

Pagination

Tabs

DropDown Tree

Category Navigation

ListBox Search

TextLineScrollable Class

Collapsible window

The boy who wants to build a botnet, haha. 

Do not trust.

I currently work on implementation of Chromium to a client. I will tell you when I finish or we can try to do it together.

Wow! 

Yes, please let me know.

Another user told me that aeldra uses the awesomium engine as a browser alternative in their client. 
Now the only question is, who can install it or maybe has already installed it.

hey,

has anyone ever dealt with the ingame browser of Metin2?

It's quite old and doesn't support some newer websites.

I would like to use the paypal payment process. However, the old metin2 browser is no longer supported

What are the possibilities?
Have any of you ever tried upgrading or even adding a completely different one?

Mfg Ente.

Closed mind ? I just said that i don't like it because it's useless ( IT IS ).And no,is not always good to have something else on the server.

This system is purely useless,you can write informations that are not yours ( facebook,skype,email etc ) and then somebody takes them and harras somebody else.Is this "good to have on the server" ... i think you are closed mind since you think so,you look forward ( like you said ) "is good to have something new" but you don't look in other ways "what impact would have this on the server".

Wow, these arguments are shit.

Good idea!

but no paypal script.

woa awesome!!!

more bugs than "his" quest.

U should delete the whole quest because the one u use is buggy

BUG: Player kills get counted twice.

I just found some old questfunctions from my old lua extensions.
On this way I spawned the ugly fences in the background:
https://metin2.download/picture/r3F9504x09DVmF8K988YXgTtGTP6KMUj/.gif

But you can't set the direction, so look for something roundly
 

-- Join a dungeon index like: 208001
function d.join_by_index(dungeonIndex,x,y)
	pc.warp(x*100,y*100,dungeonIndex)
end

-- Spawn fences: Name, Vnum, Startposition X on map,Startposition Y on map, X Space between the fences, Y Space between the fences, How many fences you want to spawn
function d.spawn_object_fence(objectName,objectVnum,objectX,objectXadd,objectY,objectYadd,objectCount)
	local i = 0
	while i < objectCount do
		d.set_unique(objectName.."_"..i,d.spawn_mob(objectVnum, objectX, objectY))
		i = i+1
		objectX = objectX + objectXadd 
		objectY = objectY + objectYadd
	end
end 
-- Delete fences: Name, How many fences of this name you want to delete
function d.delete_object_fence(objectName,objectCount)
	local i = 0
	while i < objectCount do
		d.purge_unique(objectName.."_"..i)
		i = i+1
	end
end

By the way, the d.new_jump() function is a lil bit messed up in the game 2089.
You try to join the mapindex 0, because the parameters of the function in the game are in the wrong order.

Here you can find a fix:
