@ConorO'Brien ok so i'm working on rotateoverlap right now

ok?

trying to figure out how to slice the lines

wait no

what is rotateoverlap

working on reflectoverlap, brb looking for line number

okay, starting from line 1742

top_left is the top left diagonal with a character on it (basically an axis where x + y = top_left)

And I'm trying to figure out how to calculate where to slice the line

@ConorO'Brien

trying to understand

btw sorry for bad explanation + mspaint skills

could you give me an example of how this might work?

@ConorO'Brien wdym

example program using this feature

reflect overlap?

well test.py:929 has examples of how it should work

@ConorO'Brien for a challenge submission, here

ok so I still have no idea how it works or what the problem is >_>

so in this case it reflects line to above the axis

the problem is if the overlap is large enough (the reflection is shifted down enough) lines will need to be sliced

pretend I don't know charcoal.

tell me how this works

idk how to explain, just pretend the line top_left is next to is a mirror

Charcoal reflects it across

but there's also a different command that overlaps (moves reflection closer to the axis)

so wait you're not working on rotateoverlap anymore

@ConorO'Brien no, i got the name wrong

ok

i wasn't working on rotateoverlap at all

so from what I understand you have a reflect command and it has the potential to overlap?

@ConorO'Brien yes

and this is a problem because you haven't defined behaviour for it?

no, the behavior is defined

I just have no idea how to calculate the index at which the line should be sliced

ok, why should it be sliced? if the line to reflect goes across the mirror?

yeah

so how is the line defined?

by endpoints?

yeah

although in this case we only need the left endpoint (we only need either the right or the left endpoint for any reflection)

how so?

we use the nearer endpoint to find where we need to start the write

how do you define a reflection with only one endpoint? o_O

@ConorO'Brien ?

reflect the nearest point to the axis then reflect the line starting from that point

I don't follow

what is "the axis"

the line next to top_left

it's defined as the value of x+y or x-y depending on the direction of the axis (top left to bottom right, or top right to bottom left)

oh, so its an endpoint plus a motion

yeah

ok

so, given a motion and an endpoint, determine (a) if the line intersects the mirror and (b) figure out where to cut it off so that it doesn't go past the mirror?

@ConorO'Brien yes

ok cool

and in python

is the motion given as a delta x,y pair or what?

not really

it loops for each line so x is given (reflecting y on a diagonal -> x)

y is calculated from the endpoint of the line and the diagonal (e.g. top_left)

btw managed to fix it i think

oh ok

>_>

but I think I haven't changed the cursor position to factor in overlap yet
