[Configuring client to talk to RathenaWebBuiltin]

this has good steps on setting it up.

[How to use map-server-generator.exe]

There is some documentation here: https://github.com/rathena/rathena/blob/master/doc/map_server_generator.md

for reputation, you need to pass /generate-reputation to the generator

 

So the full command would be
 

./map-server-generator.exe /generate-reputation

[Messing around with skills]

Try thinking of it this way:

AM_CANNIBALIZE summons a plant monster.

NPC_METAMORPHOSIS is a monster skill that spawns a monster from another monster (think Mi Gao).

So, try using what AM_CANNIBALIZE does, summon a monster that has a skill like NPC_METAMORPHOSIS.

[Master login]

Flux doesn't support it out of the box, you'll need to develop it yourself.

Ceres does support it, but it's pretty old and I'm not sure it'll work without some modifications.

You're looking for a feature only a couple servers have, and those servers have developed it themselves.

[DuplicateCreate and DuplicateRemove command compile error]

Change the or to an and in the while condition.

[Cart Termination Damage]

If you want to remove the 8000 cap, change it to

        case WS_CARTTERMINATION:
            i = 10 * (16 - skill_lv);
            if (i < 1) i = 1;
            if (sd && sd->cart_weight)
                skillratio += sd->cart_weight / i * 10 - 100;
            else if (!sd)
                skillratio += 80000 / i - 100;
            break;

 

[ElementProof Potions and other elemental resistance items]

There's a scroll for holy armor, you might be able to use that.

[GRF: GRF Editor]

GrfCL.exe is still a little finicky, I can't run the scripts with user input:

D:\RO\GRF Editor v1.8.2.7\GrfCL>.\"New empty GRF.bat"
Name of your GRF : data
#Log : Batch file detected an invalid encoding, changing command line arguments encoding to 1252
#Log : Breaking on general exceptions = True
#Log : Created a new GRF with the name new.grf
Progress : 0.0 %   //
//  GRF Error Handler has thrown an exception :
//  Error level : Warning
//  Message :
        Couldn't save the container file.
//______________________________________________________________________________________________________________________
#Finished
#Log : Saved the GRF to data
#BREAK -- Press any key to continue...

If I replace the input with a hard-coded string (set GRFPath=new32.grf), I get:

#Log : Batch file detected an invalid encoding, changing command line arguments encoding to 1252
#Log : Breaking on general exceptions = True
#Log : Created a new GRF with the name new.grf
#Finished
#Log : Saved the GRF to new32.grf
#BREAK -- Press any key to continue...

I get the same results if i run it through cmd or ps.

 

Any ideas?

I realize I might be one of the few that use this tool, but it's so nice.

PS: Any thoughts on how to generate thor patches?

[Failed to Read attendance configuration file]

compare yours to this one: https://github.com/rathena/rathena/blob/master/db/re/attendance.yml

Spacing is important in YAML files.

You need to remove the spaces before the achievement key.

[Extrem lags when mobbing]

what commit hash are you on right now? There was an unforeseen slowdown in accessing map data which was fixed in 48ae1a1e05db440263ac2a4fe0d887d1528151f3.

 

Sorry, didn't see the last sentence. I've no idea.

[Countinarray not working]

Interesting, the error makes it seem like you need a variable.

Try doing something like

.@cid = getcharid(2);
if (countinarray(.grbbid[0],.@cid) == 1 && .grbbday[inarray(.grbbid,.@cid)] < 40){

 

[HELP! CentOS 6.9 Compile Error]

What version of g++ do you have?

g++ --version

 

[problem with script.cpp]

     struct map_session_data *sd = script_rid2sd(st); 

should be this

     struct map_session_data *sd;
     script_rid2sd(sd);

Generally you can't just copy and paste code from other emulators, it won't work.

[Showcase: @requests forwarded to discord]

Story Time:

A lot of players run into problems. They disconnected in an instance, they bought the wrong item, someone is being a nuisance in battlegrounds. After cursing, they usually type `@request`. But alas, none of the GMs you hired are online! You need to dock their pay. The message is lost in the void.

Until now.

Discord has support for webhooks, which is a way to associate callbacks to HTTP requests. Their developer docs for webhooks can be found here. Basically, you can send a POST to your discord webhook url, and the contents will be printed to the associated channel. 

"So?"

When someone uses `@request`, the message is sent from the map server to the character server, which then sends it back to all map servers, and the map servers send the message to all connected GMs. 

Because it sends it to the character server, we're able to send the POST request from the character server. This helps performance, since the map server is constantly doing things and the character server generally uses less resources. 

"That's great! But how do we send this POST request? Do I need a stamp?"

If you're on Linux, there's a great command line tool called `curl`. It's mostly used to download files from a server, but it also has support for all other HTTP methods.

"Command line? How do we put it in rathena?"

Curl also comes with a library called libcurl that we can use in c/c++ programs! 

"I see, so we use libcurl to send the message to the discord webhook!"

Exactly!

How it looks:

Installation:

Two config options are added in this patch: gm_whisp_webhook and gm_whisp_webhook_url

This makes a change to configure, and adds a new flag. You need to add --with-lcurl to your arguments. Example: ./configure --enable-prere --enable-vip --enable-packetver=20170614 --with-lcurl

Disclaimers: 

This only works on linux. I don't run rAthena servers on windows, and neither should you. (personal opinion)

You need to install libcurl-devel. On some OSes it could be called something else; on Ubuntu, it's libcurl4-openssl-dev.

Don't ask me for a lot of help if you can't get it to work. This is supposed to be a showcase, but I'm giving the code out.

I made this in a day, it's not the greatest code. Initializing curl and cleaning up on every call is not the greatest, but unless you are getting 100 requests a minute, it should be ok for now.

Eventually, I want to add it to src/common or something. But that'll happen in a future weekend.

Code:

[Item script deactivate effect]

You can make a combo script with the two and negate the item y script.

[GRF: GRF Editor]

GrfCL seems broken, I can't run any of the example BAT scripts.

[Multiple "dimensions" of a single map]

You can make the map instanced.

[[Solved] Spawning items with elements or special attributes]

[algorithm script item_box]

Rate: Probability to get the item. Not a percentage value!

Examples:
	IG_MyItemGroup,Knife,5
	IG_MyItemGroup,Dagger,1
	IG_MyItemGroup,Jellopy,14

	- Knife has chance 5/20 (25%) to be obtained
	- Dagger has chance 1/20 (5%) to be obtained
	- Jellopy has chance 14/20 (70%) to be obtained

You add all of the numbers, and each item has a rate of number/sum.

sum = 5 + 1 + 14 = 20

Knife = 5 / 20 = 25%

Dagger = 1 / 20 = 5%

Jellopy = 14 / 20 = 70%

[Variable declaration in src]

Don't use npc_script_event; instead look at some session-less events, like OnInit or OnHourXX.

[Emote in other NPC]

use python3 instead of python2

[Status Icon without timer]

Add it to the list of permanent effects in source, status.cpp:status_change_start::L9347. The tick has to be -1.

[Status Icon without timer]

Interesting, can you show having EFST_BLESSING And EFST_WEIGHTOVER50, and what they look like in stateiconinfo.lub

What's the full path of stateiconinfo.lub

What's your client date

-------------------------

I'm sure you can get around this by sending the duration of the SI as -1 to the client.

[Status Icon without timer]

StateIconList[EFST_IDs.EFST_PNEUMA] = {
 descript = {
  { "PNEUMA", COLOR_TITLE_BUFF },
  { "Reduce variable cast time by 80%" }
 }
} 

This should work, it's the same as one without time.
