Ranked from most to least useful
Complete API for writing add-ons in Lua instead of TorqueScript.
Utility for loading DLL mods in Blockland.
Required for all DLL mods, including BlockLua.
Every server should have this add-on. Most already do.
The simplest and best floating bricks mod. Basically removes the concept of floating bricks from the game.
Other mods only make some bricks self-supporting, and if you undo one of those, say goodbye to your build. Not this one - every brick is self-supporting.
Has the side effect of fixing ownership when saving. The base game only saves the ownwership of baseplates, but this makes every brick a "baseplate" causing ownership to be saved for every individual brick.
The brick pack to end all brick packs.
Contains basically every size brick you could ever want - over 500 total - all with pixel-perfect default-style icons.
Pairs well with Client_RedBrickSize.
Adds keybinds to resize your ghost brick, automatically detecting usable bricks on the server.
Recommended usage is to set the binds to ctrl+whatever you use to shift bricks - think as if you're resizing a newdup box.
Pairs well with Brick_RedFill.
Currently-maintained fork of Zeblote's New Duplicator, with several new features and fixes.
Walkable plate that follows you around, letting you stand in midair.
Very helpful for building.
Type /ab or /autobridge to toggle.
Disabled in minigames with building disabled.
Saves the names of players who build, so if you restart the server and reload, bricks will still show names instead of a BLID.
Removes most of the limits on events. "Too many events at once!"
They can now be decently reliable, and you can make bigger contraptions.
Makes it easier to lag the shit out of the server, but it was already pretty easy.
Removes the delay after teleporting before you can interact with stuff.
Yeah, that wasn't a bug, that was intentional. No idea why.
Removes the annoying "1 observer" bottom print message.
Good for using /spy for its intended purpose.
An output event that can set the parameters of other output events (or itself?)
Turing complete. Voids your Blockland warranty.
SpawnProjectile output event, but you can use VCE replacers in the velocity fields.
Edit of the common Event_Zones, which adds the setZoneBox event.
Best used with my fork of Tool_NewDuplicator, which can set the event's zone using the selection box.
Once you have Print_Letters_Lowercase and Print_Letters_Extra (neither mine) installed, this completes the set of printable ASCII characters.
Pairs well with Server_BuildPrint.
Script to make writing with print bricks easier.
Make a print brick ghost and type /bp yourText
Automatically converts ASCII characters with no corresponding print into the closest match.
See also Client_BuildPrint.
Client-side component to Server_BuildPrint. Not required to use.
Adds the console command bp_clipboard(); which builds the contents of your clipboard out of print bricks (if the server has Server_BuildPrint).
