This topic is where I'll be keeping any spells that I think are good enough for the public eye. Note that I'm playing on 1.18 here; I make 0 guarantees that anything here or the principles behind them will work in more current versions.

Veinmine
It's veinmine. Does not detect diagonal blocks (but can be easily modified to do so). Currently always ends on a mishap, either of the null reference or too many recursions variety, and this is another thing that can be fixed probably but I can't be bothered. Uses Hexal.

Code: Select all

(
	Numerical Reflection: 19	//Post-Initialization, the stack will consist of this function (for recursive cloning) and the current target vector.
	Gemini Gambit			//Each search operation uses the target vector 3 times. 6 operations * 3 = 18, plus one for the break block at the end.
	
	Vector Reflection +X		//Each of the next six chunks will: check if an adjacent block is the same as the target block;
	Add				//push that block to the list of target blocks if so; or (0,0,0) if not; then save the new list of targets to the ravenmind.

how is directional place block supposed to work? when i try to use it wants to place blocks outside my ambit

Posted: **Sun Feb 26, 2023 4:26 pm**

Oh dear, I'll go over my code later to see if I missed an addition or subtraction somewhere.

The place block spell can actually place directional blocks based on the octant of the block that it's cast in. However, since hexcasting usually works in centers of blocks, place block is pretty much always cast at (0.5, 0.5, 0.5). To fix this, we can take an archers and an architects and work backwards to find the exact point on the block where your raycast hit, then move it along the normal so that it's comfortably inside the coordinates we want to place at.

First, we get archers + architects. then, we add half an architects to archers in order to get the face of the block we're placing against. Next, get the distance from the caster to the face of the block, multiply our look vector by that distance, and add it to our position to get the point on the block that we're looking at*. Finally we add a quarter of an architects to get the final position to use place block on.

*this formula is not actually exact and will become less accurate as distance increases. The exact formula isn't that much more complicated, but right now it looks very ugly and nobody wants to see that.

edit: I MISSED a multiplication after Numerical Reflection: 0.5

Wait, it can place blocks directionally?

wow, the more you know

I just use vanilla's code for it

Posted: **Sun Feb 26, 2023 5:26 pm**

so I tried testing that octant thing with

Code: Select all

Mind's Reflection
Compass' Purification
Mind's Reflection
Alidade's Purification
Dioscuri Gambit
Archer's Distillation
Rotation Gambit II
Architect's Distillation
Additive Distillation
{
   [(-0.25, -0.25, -0.25), (0.25, -0.25, -0.25), (-0.25, 0.25, -0.25), (0.25, 0.25, -0.25), 
    (-0.25, -0.25, 0.25), (0.25, -0.25, 0.25), (-0.25, 0.25, 0.25), (0.25, 0.25, 0.25)]
}
Scribe's Reflection	//using abacus to select octant
Selection Distillation
Additive Distillation
Place Block

but it doesn't seem to influence the direction of a block

Posted: **Sun Feb 26, 2023 7:01 pm**

After a bit more testing, it looks like only the top or bottom orientation is determined by placement location, with the N/E/S/W orientation determined by the player's look direction. This only works in 1.18.2, though; I don't know what changed for 1.19.2, but it's no longer possible to place a block in an upper orientation by moving the target vector.
