Sets the flip bit and the walking-frame set from FacingFlags. When ViewRotation is set, the heading is XORed with two so opposite headings swap.
|
||||||||
|
Keep the heading in the lowest two bits.
|
||||||||
| SetFacingFlags | CC13 | LD A,(IX+$06) | Fetch the heading. | |||||
| CC16 | RLCA | Move the heading into the lowest two bits. | ||||||
| CC17 | RLCA | |||||||
| CC18 | AND %00000011 | Keep only the heading. | ||||||
| CC1A | LD L,A | Keep it in L. | ||||||
|
XOR the heading with two if ViewRotation is set.
|
||||||||
| CC1B | LD A,($A268) | Fetch ViewRotation. | ||||||
| CC1E | ADD A,A | Double it. | ||||||
| CC1F | XOR L | XOR it with the heading. | ||||||
| CC20 | LD L,A | Keep the index in L. | ||||||
| CC21 | LD H,$00 | Clear H. | ||||||
| CC23 | LD BC,$CCBE | Point BC at FacingFlags. | ||||||
| CC26 | ADD HL,BC | Find the entry. | ||||||
|
Set bits 6 and 7 of the flags.
|
||||||||
| CC27 | LD A,(HL) | Fetch the entry. | ||||||
| CC28 | AND %11000000 | Keep bits 6 and 7. | ||||||
| CC2A | LD C,A | Keep them in C. | ||||||
| CC2B | LD A,(IX+$07) | Fetch the flags. | ||||||
| CC2E | AND %00111111 | Clear bits 6 and 7. | ||||||
| CC30 | OR C | Set them from the table. | ||||||
| CC31 | LD (IX+$07),A | Set the flags. | ||||||
|
Set bit 2 of the walking frame.
|
||||||||
| CC34 | LD A,(HL) | Fetch the entry again. | ||||||
| CC35 | AND %00000100 | Keep bit 2. | ||||||
| CC37 | LD C,A | Keep it in C. | ||||||
| CC38 | LD A,(IX+$0C) | Fetch the walking frame. | ||||||
| CC3B | AND %11111011 | Clear bit 2. | ||||||
| CC3D | OR C | Set it from the table. | ||||||
| CC3E | LD (IX+$0C),A | Set the walking frame and return. | ||||||
| CC41 | RET | |||||||
