What it does

Bouncy blocks in several colours are added to the game, and each colour can be used to build bouncing surfaces on a server. The mod depends on Filament, and it is open source under the GNU Lesser General Public License v3.0 only. Builds exist for 1.21.6 – 1.21.10 on Fabric, and snapshot builds are published too.

Server owners who want bouncy areas can place these blocks without asking players to add anything to their clients. Public links for the source code and the issue tracker are available.

Key features

  1. Colourful bouncy blocks

    Blocks in several colours make players bounce when they land on them, which suits parkours and play areas.

  2. Dye-based crafting

    Each bouncy block takes eight slime blocks and a single dye, arranged with the dye in the center cell of a 3x3 crafting grid.

  3. Resourcepack sharing

    When Polymer's autohost is enabled, the server shares the resourcepack with players as they join.
