Bounding Box Outline Reloaded
Highlight structures and features to help build farms and spawn proof
About this Mod
This mod highlights in a variety of colors and styles the different structures & features of the game:-
- Nether Fortresses; red boxes bound each individual area where Blaze, Wither Skeletons & normal Skeletons will spawn. Time for a beacon methinks!
- Witch Huts; blue boxes reveal everywhere only witches spawn. Witch farm anyone?
- Desert Temples; orange boxes envelop the pyramid and towers. Go grab some loot but beware TNT boobie traps!
- Jungle Temples; dark green boxes surround the temple. Indianna Jones would've loved these!
- Ocean Monuments; cyan boxes indicate where guardians spawn. Sea lantern and prismarine block types FTW.
- End Cities; magenta boxes show the rooms, corridors and airships in the End. Time to fall with style!
- Strongholds; yellow boxes show each room in the stronghold. Does anyone make anything with silverfish spawners?
- Woodland Mansions; brown boxes show each room in the woodland mansion. Here's Johnny!
- Mine Shafts; light gray boxes illustrate each of the mine shafts. Cobwebs... grrr!
- Villages; gray boxes designate each building in the generated village. Check out the blacksmith loot chest!
- Slime chunks; dark green boxes highlight where slimes will spawn, with a dynamic box that rises to where the players' feet are to help find them from the surface. Bouncy... bouncy...
- World Spawn & spawn chunks; red boxes outline the world spawn and the spawn chunks (active & lazy).
- Igloos; white boxes show where igloos are. Maybe you can convert the zombie villager back?
- Shipwrecks; cyan boxes are like a lighthouse those wary sailors wish they'd had. Time to find some buried treasure?
- Ocean ruins; cyan boxes show the different ocean ruin structures. Watch out for those pesky drowns tho!
- Buried treasure; cyan boxes highlight where the heart of the sea can be found. Conduit anyone?
- Mob Spawners; bright green boxes show where mob spawners are, where mobs will be spawned, and red/orange/green lines help the player see if a spawner is nearby and activated.
- Pillager Outposts; dark gray boxes outline where crossbow-wielding pillagers will spawn. Beware of bad omens tho!
- Flower forests; colorful squares show where each flower type will grow in the flower forest... Let's make a pretty bouquet.
- Bedrock ceiling; bright green blocks show where bedrock is only one block thick on the nether ceiling. Time to make a farm on the nether ceiling.
