This will fail if there's anything else on the stack. I published two macros more than a year ago that do the same thing with Running Sum Purification but without such issues or side effects.

This hex is a proof-of-concept for using Mouse Input to draw a mouse cursor on Mediaworks' Macula. Required macros: Mouse Input, Minimization Distillation Video demo [pat=qqq dir=w] [pat=awawa dir=w][pat=aaddaddad dir=e][pat=qqq dir=w] [pat=aqdee dir=sw][pat=d dir=e] [pat=eee dir=e][pat=qwaeawq dir=...

This is a set of macros and hexes that demonstrate a technique for implementing 2D mouse input in Hex Casting. It works by getting the relative pitch/yaw between the player's current look direction and a known reference direction. Mouse movement in Minecraft directly affects the pitch (y) and yaw (x...

Theta Distillation vec1, vec2 → angle Returns the unsigned angle (in radians) between two vectors. [pat=awddeeeeeqa dir=nw] [pat=qqq dir=w] [pat=aadadaaw dir=e][pat=waqaw dir=se][pat=ddqdd dir=ne][pat=wqaqw dir=ne][pat=aawdd dir=e][pat=wqaqw dir=ne][pat=waqaw dir=se][pat=wdedw dir=ne][pat=adeeeee d...

This hex allows you to build a circle on the fly by drawing patterns with your staff. When the wisp summoned by the hex receives a pattern iota over a link, it moves one block in the direction you're looking (if necessary), then writes and places a slate. This works very well in combination with Ope...

Heaps This is a set of macros that can be used to implement "heap memory" in Hex Casting - a system that allows random access to integer memory addresses within a cube of in-world focuses. Requires Hex Gloop, or any other mod that allows you to fit one focus per block (ie. not item frames...

Splicing Table This is a ComputerCraft program that implement an ingame "hex editing" tool. This is meant to make writing hexes without external tools more feasible/enjoyable. The contents of the list are displayed by sending them to a wisp and revealing them with Gloop. It includes a bun...

Inverse Tangent Distillation num, num → num Implements atan2() (specifically the "variant [...] that avoids [the] inflated rounding errors" on this page ). Kristi Fristi posted a similar macro in this thread a while ago, but this version takes 12 fewer patterns and actually works. Note: a...

Implements Conway's Game of Life (lmao). This hex summons a wisp that runs one step of the game every 4 ticks (adjust by replacing the number literal at index 1). It clears the previous step just before the next iteration by making a bunch of lines behind the grid to hit the particle limit - that's ...

Toroidal Selection Gambit [any], num → any, any, any Selects the iotas before, at, and after the given index. Wraps around at the edges. [pat=qaeaqweeeee dir=nw] [pat=qqq dir=w] [pat=aadadaaw dir=e][pat=aqaaw dir=se][pat=wddw dir=nw][pat=aaedd dir=e][pat=aqaeaq dir=e][pat=ddqaa dir=e][pat=waaw dir=...
