In the 1.21.4 update (9277aa33e97456c94b5f7d1aa54e00e204a316dd), we removed our DirectVertexBuffer class, and switched to vanilla's VertexBuffer. This forced us to use MeshData and thus ByteBufferBuilder instead of allocating the ByteBuffer ourselves. One thing I'd missed with this is that Iris's text vertex sink API requires us to allocate the whole buffer up-front and so the resulting buffer has a limit of the *maximum* number of vertices rendered, not the actual one. This wasn't an issue on 1.21.4, as we didn't check this (I guess we just silently rendered junk??), but for the 1.21.5 update (a1df19667361601c7f37a71074ea7755ccc4019d) we added some extra assertions here, which now fail on Iris. Typically, the whole original change was is now entirely redundant, as Vanilla has removed VertexBuffer entirely, and so we can/should work in terms of raw ByteBuffers again. Fixes #2219.

CC: Tweaked is a mod for Minecraft which adds programmable computers, turtles and more to the game. A fork of the much-beloved ComputerCraft, it continues its legacy with improved performance and stability, along with a wealth of new features.
CC: Tweaked can be installed from Modrinth. It runs on both Minecraft Forge and Fabric.
Contributing
Any contribution is welcome, be that using the mod, reporting bugs or contributing code. If you want to get started developing the mod, check out the instructions here.
Community
If you need help getting started with CC: Tweaked, want to show off your latest project, or just want to chat about
ComputerCraft, do check out our GitHub discussions page! There's also a fairly populated,
albeit quiet IRC channel on EsperNet, if that's more your cup of tea. You can join #computercraft
through your
desktop client, or online using KiwiIRC.
We also host fairly comprehensive documentation at tweaked.cc.
Using
CC: Tweaked is hosted on my maven repo, and so is relatively simple to depend on. You may wish to add a soft (or hard)
dependency in your mods.toml
file, with the appropriate version bounds, to ensure that API functionality you depend
on is present.
repositories {
maven {
url "https://maven.squiddev.cc"
content {
includeGroup("cc.tweaked")
}
}
}
dependencies {
// Vanilla (i.e. for multi-loader systems)
compileOnly("cc.tweaked:cc-tweaked-$mcVersion-common-api:$cctVersion")
// Forge Gradle
compileOnly("cc.tweaked:cc-tweaked-$mcVersion-forge-api:$cctVersion")
runtimeOnly("cc.tweaked:cc-tweaked-$mcVersion-forge:$cctVersion")
// Fabric Loom
modCompileOnly("cc.tweaked:cc-tweaked-$mcVersion-fabric-api:$cctVersion")
modRuntimeOnly("cc.tweaked:cc-tweaked-$mcVersion-fabric:$cctVersion")
}
You should also be careful to only use classes within the dan200.computercraft.api
package. Non-API classes are
subject to change at any point. If you depend on functionality outside the API (or need to mixin to CC:T), please file
an issue to let me know!
We bundle the API sources with the jar, so documentation should be easily viewable within your editor. Alternatively, the generated documentation can be browsed online.
