PortalBackport

portal-backport

简体中文 Port of Nether Portal features from Minecraft 1.21+ (includes TNT-related fixes)

Currently Ported Features: - Allows falling blocks to pass through Nether portals - Allows primed TNT entities to pass through Nether portals - TNT passing through portals will no longer destroy portal blocks

TNT-Related Fixes: - TNT retains the activator entity's data after portal traversal - Preserves the portal traversal flag in TNT's `Teleport` field (fixes a bug where reloading chunks containing portal-traversed TNT would cause it to destroy the portal) - Stores the igniter entity's UUID in TNT's `Owner` field (Note: Due to underlying engine limitations, this is a partial fix and does not guarantee successful entity resolution after world reload)

Explicitly Excluded Features: - Teleportation of riding entities (requires extensive breaking changes and code injection) - Non-player entities generating new portals in the target dimension when no valid exit exists (intentionally excluded to prevent breaking existing portal-based contraptions)
