Many people don't really like having to use command blocks to make adventure maps with very complicated codes and stuff, so i suggest an easy to use customiser for items and blocks.
•In creative you can change the name, enchantments, unbreakable and lore attributes easily.
•You can open a menu and set a left/right click detection which can trigger certain things to happen like summoning, particle effects and other events.
•You can easily set a scoreboard.
•Easy particle wand, where you can right click somewhere and set particle effects before uploading it to a command block.
•Easy tell raw or /say with a speech block which has to be triggered with redstone which allows you to change the color and font of your desired text easily.
•Easy cloning wand which allows you to set what you want to clone and where to before uploading to a command block.
Edit-After you have completed the adventure map, people don't need the mod to play the adventure map.
I'd have it so that you don't need the mod itself to play maps created with the help of this mod.
My output of snark depends on your output of stupidity.
My patience wears thin on strawmen and lies.
yes, i forgot to say that
