xItemLib

The modular custom item library​


xItemLib is a packageable library, allowing for easier creation of custom kart items.
A functional custom item can be made in minutes, thanks to the easy to understand "event" system.
The library takes care of all complex logic related to item distribution, so the creator only has to worry about making the item itself.

Documentation

The library also comes with small quality of life improvements to regular gameplay, seen through console commands:
  • listxitem lists all loaded items,
  • xitemdebugitem (server OP command), the replacement for kartdebugitem, features an improved interface, as well as both name and internal name searching in addition to standard numerical selection,
  • xitemdebugamount (server OP command), which replaces kartdebugamount, is fully uncapped and can give item amounts past 255,
  • xitemdebugdistributions (server OP command), shows a graphical distribution debugger when turned on,
  • togglexitem (server OP command), which replaces vanilla item toggles, use this to disable items from showing up in the roulette,
  • xitemroulette on/off toggles an improved client sided item roulette which only displays obtainable items at any given time, inspired by a similar feature in CTGP-7,
  • xitemrouletteanim on/off toggles a less static item roulette animation.

To showcase what the library can do, a sampler pack containing various custom items is also available.
xItem_jarate
Jarate
(+ Orbinaut)
A jar containing a strange yellow fluid. Throw it at your opponents to soak them in Jarate! Sodden opponents take Mini-Crits when hit or bumped.
Follow up with the included Orbinaut!
Throw Ahead
/
Drop Behind​
xItem_pipe
Pipe
A warp pipe taken straight from the Mushroom Kingdom.
The magic required for them to function may not exist in the numerous worlds you'll be racing in, so using one as a solid obstacle will do just fine.
Drop Behind​
xItem_launcherBombhei
Mine Cannon
A dangerous cannon fueled by red-hot coals!
Will slowly shoot primed Mines for a set period of time.
Equip​
xItem_kouraBlue
Spiny Shell
You're first and doing so well
But here comes the Spiny Shell!

Immediately chases first place when used, passing by every other racer on it's way. Taking on it's latest incarnation, the Spiny Shell won't land until it has fully locked on to First Place.
Throw Ahead​
xItem_dkrMagnet
DKR Reverse Magnet
A magnet so strong, no kart is safe from it's attraction! Hold the Item button to lock on to a target, and release to make them fly towards you! Be careful, as using it with no target nearby will consume the magnet.
Special​
icnExodia.png
Pot of Greed
"Draw two cards."
Use this magical card to draw two Exodia pieces. Summon Exodia when 5 are collected, and hit everyone ahead! Racers further ahead get hit harder.
Special​
gagMicroIcn.png
Eggman Microphone
Use this powerful microphone to play a famous quote from Eggman himself! The power of his announcement spins out anyone ahead of you holding onto an item! If you're being targeted by the Eggman Microphone, use your item before the countdown ends!
Special​
icnPickelAxe.png
Stone Axe
When in main hand:
0.8 Attack Speed
9 Attack Damage
This blocky yet powerful melee weapon is enchanted with Cleaving III, an experimental enchantment that prevents the use of a target's items on hit! Don't forget about critical and sprint attacks!

Welcome to releases! The tech here is incredible, and I'm glad to see this as a cool resource for others to potentially use, but I'm not sure if the mine thrower lasting this long is such a good idea outside of Mario Kart Tour, and the blue shell... was absolutely something I didn't want to see return, but I appreciate the items being present as a showcase, and I was surprised when holding multiple Mine Launchers deplyed them all at once like they do in Tour! Sadly, I can't personally test how the item pool distributation works in a large netgame, so I can't in full faith judge that part.
