Author	SHA1	Message	Date
Kistaro Windrider	528e67045d	Trimming Trim up redundant nil checks, sequential assignments that could be on a shared line, and repeated references to a deeply nested variable.	2022-12-23 00:34:00 -08:00
Kistaro Windrider	1995501583	Save tokens on movemebnt checks I promise this is mathematically equivalent-ish to the original. (0.2 and its multiples are nonterminating decimals in base 2, so there's a little jank when the negative shift right is a shift left.)	2022-12-23 00:18:50 -08:00
Kistaro Windrider	9d93f30426	Fix crate math. I forgot that -1 & 1 = 1 rather than 0 so all the bit math didn't work. But I can fix it with polynomial algebra! this is much better.	2022-12-23 00:02:02 -08:00
Kistaro Windrider	0fe3b1699f	packed crate representation don't bother exploding crates into four bools, and then comparing them all individually to a bunch of conditions. absurd bit manipulation bullshit saves cycles and tokens. leaving a crate's movement rule represented as four bits means we can exploit our previous calculation of dx1 and dy1, which must each either be 0x0001 or 0x8FFF, and violently hammer them down to align with this bit-packed representation, giving this glorious little atrocity.	2022-12-22 23:15:03 -08:00
Kistaro Windrider	b10447bb86	comment the bullshit it needs it	2022-12-22 22:50:34 -08:00
Kistaro Windrider	fe3a68284f	replace comparisons with bit math bullshit integers in the range [0, 15] fit entirely in the bit mask 0x000F. integers out of that range will have at least one bit 0x0010 or higher, or will have the sign bit 0x8000 set. so to find out if one of two numbers is out of range [0, 15], we can check the bit mask of their bitwise or. this saves tokens and cycles. it is also completely illegible. very in the spirit of Pico-8, I love it.	2022-12-22 22:49:27 -08:00
