How to Enable Collision Fix Only on Specific Servers

Why Per-Server Control Matters

Disabling client-side collision checks is great for performance, but on some servers you may want vanilla-feeling pushing, or the server may already handle collisions in a way that conflicts. Collision Fix supports enabling its behavior only on servers you choose, so you keep normal behavior everywhere else.

Add a Server to the Allowed List

1. Open the mod's config and find the server-specific or per-server section.

2. Add the address of the server where you want Collision Fix active. Use the same address you type in the multiplayer server list.

3. Make sure the per-server toggle is enabled so the mod only applies its collision changes on listed servers.

4. Save the config.

Verify It Is Working

Join the listed server and test by walking into another player or a mob. If pushing is removed there but still present on an unlisted server, the per-server filter is working. If behavior is identical everywhere, the global toggle may be overriding your list, so turn the global option off and rely on the server list instead. This setup is handy for players who want smooth movement on laggy public servers while keeping normal physics on private worlds.
