Someone should make a mod that changes it so nobody except the host and super admins can spawn any item unless they have a blueprint of it.
Slash commands -
/giveblueprint [player] [blueprint] - Gives the player the blueprint.
/clearblueprings [player] - Clears all the players blueprints
/giveallblueprints [player] - Gives the player all the blueprints
Events
self>addBlueprint [item] - Adds a blueprint to the brick. You can spawn the item on that brick only.
self>spawnBlueprint [item] - It spawns like an item. Its the building tool but blue and if you pick it up that blueprint is added to your blueprints.
bot>holdBlueprint [item] - The bot will have the blueprint in their blueprints. If the bot is killed you will get their blueprints.
player>giveBlueprint [item] - Gives the player the blueprint. (If its possible make it so this will not work unless its on a brick a super admin/host built)
Great for rps that let you invent stuff. Or fort DMs, if you dont want everyone to go crazy with miniguns or something.
