JoaCarpet
A small Carpet extension mod.
Carpet Mod Settings
insaneBehaviors
Makes the random velocities of droppers and projectiles (as well as both the position and velocity of blocks broken by pistons) systematically iterate through the most extreme values possible, and then repeatedly iterate through all the halfway points in between, in a sense attempting every point in a 3d/5d "grid" that slowly increases in resolution.
For droppers and projectiles, this setting determines whether the max value corresponds to the old gaussian randomness limits ("extreme"), or the limits of the triangular randomness introduced in 1.19 ("sensible"). Both settings function the same for blocks being broken by pistons.
For the /insanebehaviors <reset/getstate/setstate> command, see /carpet commandInsaneBehaviors.
Do note that insaneBehaviors works on a global iterator: any triggering event will step through an iteration from all other insaneBehaviors events, too.
- Type:
String - Categories:
CREATIVE,JOA - Options:
extreme,sensible,off - Default value:
off
commandInsaneBehaviors
The command used for the insaneBehaviors rule.
"reset" sets the resolution and counter back to the default values. "getstate" and "setstate" are used to manually read and write the current iteration state.
- Type:
String - Categories:
COMMAND,CREATIVE,JOA - Options:
true,ops,false,0,1,2,3,4 - Default value:
ops
insaneBehaviorsIncrement
Determines the incrementing behavior of the insaneBehaviors rule. If set to normal, the counter increments normally until all points of the current resolution have been exhausted, then step to the next resolution.
loopCurrentResolution will instead restart at the beginning of the current resolution.
Freeze will stop both the counter and resolution from incrementing.
- Type:
String - Categories:
CREATIVE,JOA - Options:
normal,loopCurrentResolution,freeze - Default value:
normal
insaneBehaviorsSkipVisitedPoints
Makes the insaneBehaviors rule skip points that coincide with previous resolutions, reducing the overall search space by a fraction that approaches 1/(2^resolution)
- Type:
Boolean - Categories:
CREATIVE,JOA - Options:
true,false - Default value:
false
insaneBehaviorsCartYeetingException
Makes testing cart yeeting possible by disabling one of the two types of item drops (vehicle item and container items), to make the different iterators not interfere with each other.
- Type:
String - Categories:
CREATIVE,JOA - Options:
none,disableVehicleItem,disableContainerContents - Default value:
none
blockTickling
Lets you send manual block and/or shape updates to blocks using a feather item. Shape updates are sent from the block in front of the face you're clicking on. Useful if you're working with update interactions off or with budded blocks.
- Type:
String - Categories:
CREATIVE,JOA - Options:
off,blockupdates,shapeupdates,both - Default value:
off
disableEndermanGriefing
Disables enderman griefing.
- Type:
Boolean - Categories:
SURVIVAL,JOA - Options:
true,false - Default value:
false
disableElytraRockets
Disables using rockets with elytra.
- Type:
Boolean - Categories:
SURVIVAL,JOA - Options:
true,false - Default value:
false
verticalRocketsFromStandstill
Makes rocket flying only activate while standing on the ground, and makes it only propel you upwards. Disables using rockets while already flying.
Only works in singleplayer, or with JoaCarpet installed both serverside and clientside.
- Type:
Boolean - Categories:
SURVIVAL,JOA,EXPERIMENTAL - Options:
true,false - Default value:
false
verticalRocketPower
The vertical acceleration power used with the verticalRocketsFromStandstill rule.
- Type:
Double - Categories:
SURVIVAL,JOA,EXPERIMENTAL - Default value:
