Customizing Your Server
Once you know how to build and configure your server correctly, the next thing you may want to know is how to tweak it to your liking
What can I change?
There are some limitations, though. In some cases such as spells, the client is programmed to know what is possible. If, for example, you give a Paladin the spell "Fire," the client knows that this is impossible and will not allow the spell to be cast under any circumstances unless the Paladin would gain it from a correct method, such as having Black Mage as a subjob. This also applies to level.
Note that this list may not match what you're used to seeing in retail, which is why Red Mage has spells like Hastega on their spell list if you use @addallspells. Things like equipment levels and job requirements, as well as Dual wield are enforced in a similar manner. However, job abilities can be swapped around with relative ease.
Another common question is changing NPC/monster names. While the appearances are determined by the server, the client has a list of names that belong to specific entity IDs (monsters and NPCs) in any given zone. You might see that they're named in the database, but that's for scripting and identification purposes. Those names have no bearing on what you'll see in-game. So the short answer is, you can't. The long answer is you'd have to decipher the DATs and edit them to change the name, and then distribute a tool to automatically make those changes for your players.
Where do I change things?
A lot of the options can be found in scripts/globals/settings.lua including Initial level cap, maximum level allowed on the server, starting gil, starting inventory, unlocking subjobs by default, unlocking advanced jobs by default, and a plethora of other settings to tweak your server. See the file itself for details.
Note that some of the options are not in use, but the ENABLE_ series along with the Character Config section will cover many popular requests, and should be largely working. Harvesting settings, Dynamis Settings, AF settings, FIELD_MANUALS, and EXPLORER_MOOGLE and level cap will also be working, to easily control those features.
Experience rate can be found in conf/map_darkstar.conf. Change exp_rate: to whatever multiplier you want. If you set it to 2.0 it will give you double experience for all monsters as per the experience tables.
If you prefer to modify the experience granted directly, you can find those values in the exp_table mysql table. To change the amount of experience required to progress to the next level, modify the exp_base mysql table.
Default Character Speed
To adjust the default character run speed, edit src/map/baseentity.cpp and look for a line that says
speed = 40;
and modify it accordingly. Maximum effective value is 255, and the official test server uses 60.
Starting Jobs and Levels
If you want to change the default starting level for any/all jobs, in the char_jobs table, you need to set the default value for each 3-letter job code to what you want to be the starting level for that job.
You can also change the jobs you have unlocked by default here, but it is easier to use settings.lua if you want to unlock all jobs at the start. Nevertheless, if you wish to tweak exactly what jobs are unlocked, you can adjust the 'unlocked' field by adding together the values of all the jobs you desire below.
Adjust Healing while Resting
In scripts/globals/effects/healing.lua find the lines:
target:addMP(12+((healtime-2) * (1+target:getMod(MOD_CLEAR_MIND)))+(target:getMod(MOD_MPHEAL)));
and adjust the 10, 10, and 12 appropriately to change the base healing amounts.
To change the name your server provides when people log in, replace all instances (currently 2) of DarkStar in src/login/lobby.cpp with whatever you want.
To make an NPC that adds things like maps, jobs, and spells will require a basic understanding of Lua scripting and logic. Refer to How to Make a Quest for a good primer. If all else fails, find an NPC that does what you want and read their code.
First, select the NPC you'd like to modify. The method used on Whasf's server is the "Adventurer's Coupon" turn in, but it's really up to you. Their logic can be located in /scripts/zones/zone_name/npcs/npc_name.lua. If the file doesn't exist, you can create it from a text document; just make sure it follows the npc_name.lua convention, and not .txt.
Second, decide what has to be done to trigger the bonuses. Just talk to the NPC? Trade an item? Meet specific conditions, such as being Rank 2, or under level 20? Code your conditions accordingly.
Third, program your unlocks. Refer to ID References for full details on key items, maps, spells, and items. The following code samples cover a few basic rewards:
-- Adds all maps (Pre-SoA, no Dynamis) player:addKeyItem(385); player:addKeyItem(386); player:addKeyItem(387); player:addKeyItem(388); -- ITEMS 389 to 447 z = 389; while z <= 447 do player:addKeyItem(z); z = z + 1; end -- KEY ITEMS 1856 to 1893 z = 1856; while z <= 1893 do player:addKeyItem(z); z = z + 1; end -- Adds all 3 starting nation rings player:addItem(13495); player:addItem(13496); player:addItem(13497); -- Unlocks subjob player:unlockJob(0); -- Grants gil and gives the appropriate message player:addGil(500000); player:messageSpecial(GIL_OBTAINED,500000); -- Grants a small amount of fame player:addFame(BASTOK, BAS_FAME*10); player:addFame(SANDORIA,SAN_FAME*10); player:addFame(WINDURST,WIN_FAME*10); player:addFame(NORG, NORG_FAME*10); -- Unlocks Dark Knight player:unlockJob(8);
Finally, test your NPC for bugs. If anything is wrong, you'll see error messages in the DSGame-server window of your server. Make sure you haven't missed a semi-colon, left a parenthesis open, or missed an "end" after an "if."
These can also be triggered in /scripts/globals/player.lua inside the CharCreate() function to grant them to new characters as they're created.
