The ForceBlocks plugin allows for an effective barrier around the placed ForceBlock that can either push or pull surrounding monsters and players.

Commands:

In order to get a force block you must hold a block such as obsidian, crying obsidian or netherite and type the command:
/applyforceblock <radius>

The radius can be anything you like although don't go too high as this may crash the server. I would recommend 10.

In order to allow other players to walk around the land protected by the ForceBlock unaffected, the player who placed it must do the command: /forceblocktrust <player>

An admin command to bypass all Force Blocks is:
/bypassforceblock

Some other fun commands in this plugin include:
/projectileaimbot
/reach <reach>
/follow <player>

Permissions:
forceblock.apply - /applyforceblock
forceblock.projectileaimbot - /projectileaimbot
forceblock.reach - /reach
forceblock.follow - /follow
forceblock.bypass - /bypassforceblock
