Frequently asked questions

Do I need to install CodeChickenLib separately or does it come with other mods?
CodeChickenLib Unofficial is included automatically in CodeChickenCore Unofficial version 1.3.0 and newer, so you don't need a separate download if you have that mod. If you're using mods that depend on CodeChickenLib but don't have CodeChickenCore, you'll need to install it as a standalone library.
What does 'ASM systems' mean and why do I need it?
ASM systems allow CodeChickenLib to modify how Minecraft's code behaves at runtime, letting legacy mods work correctly without rewriting their entire source. You don't need to configure it manually—it runs automatically in the background to keep dependent mods functioning.
I'm getting packet errors between my client and server. Where do I start?
Check that CodeChickenLib is installed on both your client and server with matching versions. If versions mismatch or the mod is missing on one side, network packets will fail to sync; see the Troubleshooting Network Packet Errors guide for diagnostic steps.
Can I use CodeChickenLib with mods from different Minecraft versions?
No—CodeChickenLib is version-specific and only works with mods built for the same Minecraft version. Installing it on a version it wasn't designed for will cause crashes or silent failures.
