About this Mod

TC Cobble Flight is a Minecraft mod for Fabric that adds natural flight behavior to wild Flying-type Pokémon in Cobblemon. Instead of spawning stationary on the ground, eligible Pokémon will take off, soar through the air, and land dynamically based on their surroundings and type characteristics.
Each Pokémon moves at its own speed and altitude, influenced by its type, weight, and individual traits. A Pidgeot will fly faster and higher than a Beautifly; a Steel/Flying type will be sluggish but persistent. Flight patterns include smooth takeoffs, gentle mid-air sway, and gradual landings — making wild Pokémon feel alive rather than static.
The mod only affects wild Pokémon. Owned, battling, or otherwise occupied Pokémon are left completely untouched.
Features:

Dynamic takeoff, cruising, and landing states per Pokémon
Speed, altitude, and stamina scaled by type and weight
Spawn position awareness — tree perches vs open sky
Player proximity increases the chance of a Pokémon taking flight
Whitelist/blacklist support for individual species
Fully configurable via flyingspawn.json (Cloth Config)

Frequently Asked Questions

TC Cobble Flight server crashes on startup – what to do?

Most common cause: wrong fabric version or insufficient RAM. Check the server log (latest.log) for "OutOfMemoryError" or "Mixin" errors. With Mado Hosting: ensure at least 3 GB RAM is allocated and the loader matches the mod version (1.21.1). You can switch loaders with one click in the panel.

Is TC Cobble Flight compatible with fabric?

TC Cobble Flight officially supports fabric for Minecraft 1.21.1. The Mado dashboard automatically detects incompatible loader combinations.

Server lagging with TC Cobble Flight – how to optimize performance?

Recommended RAM: 4 GB (per 8 players). Use /spark profiler to check if TC Cobble Flight consumes the most tick time. Common fixes: reduce server view-distance to 8-10, install "performant" or "starlight" as supplementary mods on Forge. With Mado Hosting, your server runs on NVMe SSDs with dedicated CPU cores for minimal latency.
