IBCarpet

IBCarpet ports the Insane Behaviors feature from JoaCarpet to a newer version of Minecraft. Insane Behaviors gives the user control over the random number generator that item entities use for position and velocity, and it can force unlikely numbers to appear without waiting for them to occur. The mod is configured through Carpet, so the Carpet options named insaneBehaviors and ibDistribution are used to switch the feature on and choose a distribution.

By default IBCarpet applies a three-peaked distribution with a moderate extremeness setting. The ibDistribution option picks how random numbers are drawn. Most of Minecraft's item entity position and velocity randomness is replaced this way, while some values use a uniform distribution instead of the vanilla triangle distribution. The vanilla triangle shape has its peak at 0, and the chance of a number falls as it moves toward -1 or 1. Setting insaneBehaviors to false turns everything off and returns the game to vanilla behavior.

The mod changes what happens when a minecart is broken, when a piston breaks blocks, when containers such as chests, droppers and hoppers are broken, and when dispensers, crafters and droppers dispense items. A dropper that dispenses items in random directions can send one or a few items on a different path each time.
