MapperPlugin

Most of its features arrive as commands. A command executor is usually a player object, so the mod lets a command change which entity or player executes it. The command set is designed for map creators and needs only permission level 2 to run.

The mod adds game rules that change damage handling: mobDamageInvulnerable and playerDamageInvulnerable both default to true and control how long entities and players stay invulnerable after a hit. Other additions let a command merge data into a player, grant a multi-jump ability, and set the pitch limits of display entities, which vanilla restricts to -90F through 90F. A separate NBT option controls whether a Wither shows its boss bar.

Particle and interface settings are configured on the client side. Map creators can set particle colour, scaling, lighting and gravity influence, cap the maximum number of particles, and choose which sound listener receives a source. The client-side browser component needs MCEF, and its maximum wait time for JavaScript messages is configurable. The mod runs on client and server, so both sides need it, and it is published for Fabric and NeoForge for 1.21 – 1.21.1.
