BATTLE.BIN : Movement Routine Called while spreading Move AoE. Each time it's called (always 4 times ?) it checks a different elevation and path (Path on Tile or Path above unit). If Tile is a Valid and efficient destination it is flagged to become a future origin ------------------------------------------------------------------------------------------------------------------------- Parameters : r4 - Some Counter : Determines destination's elevation and tested Path r5 - Preset value : used as a movement malus Returns : r2 - 0x00 if Valid Path (Possible and best) (only returned value checked ?) Destination Tile is flagged to be a future Origin - 0x01 Destination flags 0x20 and 0x08 are OFF (Above unit path) - 0x02 Destination flags 0x10 is OFF (Tile path) - 0x03 Tile is too steep : flag 0x04 ON and Higher destination (Tile path) - 0x04 Destination ceiling is too low (< than exit + size) - 0x05 Origin Ceiling is too low (< Entry) - 0x06 Destination ceiling is too low (< then Entry + Size) - 0x08 PV <> 0x00 and Destination is higher - 0x09 Acting Unit cannot Jump the vertical drop - 0x0b Movement cost is too high (Unit Path) - 0x0c This Path is a detour (Unit Path) - 0x0d This Path is less convenient (Higher Vertical drop) (Unit Path) - 0x0e Movement cost is too high (Tile Path) - 0x0f This Path is a detour (Tile Path) - 0x10 This Path is less convenient (Higher Vertical drop) (Tile Path) - 0x11 Destination flags 0x20 (Unit Path - Exit without Updating moves) ------------------------------------------------------------------------------------------------------------------------- 00175958: 27bdffd8 addiu r29,r29,-0x0028 | 0017595c: afb00010 sw r16,0x0010(r29) | 00175960: 3c108019 lui r16,0x8019 | 00175964: 8e10f4e4 lw r16,-0x0b1c(r16) |Pointer to Scratch Pad 0x1f800180 00175968: afb3001c sw r19,0x001c(r29) | 0017596c: 00a09821 addu r19,r5,r0 |r19 = Preset Value 00175970: afb20018 sw r18,0x0018(r29) | 00175974: 3c128019 lui r18,0x8019 | 00175978: 8e52f4e0 lw r18,-0x0b20(r18) |Pointer to scratch pad 0x1f800000 0017597c: 3c058019 lui r5,0x8019 | 00175980: 8ca5f4f0 lw r5,-0x0b10(r5) |Pointer to Scratch Pad 0x1f800200 00175984: 3c068019 lui r6,0x8019 | 00175988: 8cc6f4e8 lw r6,-0x0b18(r6) |Pointer to scratch pad 0x1f800080 0017598c: afb40020 sw r20,0x0020(r29) | 00175990: 3c148019 lui r20,0x8019 | 00175994: 8e94f4ec lw r20,-0x0b14(r20) |Pointer to scratch pad 0x1f800100 00175998: 30820001 andi r2,r4,0x0001 |Elevation flag (0 , 1 , 0 ,1) 0017599c: afbf0024 sw r31,0x0024(r29) | 001759a0: afb10014 sw r17,0x0014(r29) | 001759a4: a6020034 sh r2,0x0034(r16) |Store elevation flag 001759a8: 000417c2 srl r2,r4,0x1f |always 0 ? 001759ac: 00822021 addu r4,r4,r2 | 001759b0: 86030032 lh r3,0x0032(r16) |Destination Y 001759b4: 00042043 sra r4,r4,0x01 |Counter / 2 ( 0 0 1 1) 001759b8: a2040042 sb r4,0x0042(r16) |Store Tile/Unit path flag 001759bc: 92420018 lbu r2,0x0018(r18) |Load Max X 001759c0: 00000000 nop | 001759c4: 00620018 mult r3,r2 | 001759c8: 86020034 lh r2,0x0034(r16) |Load elevation flag 001759cc: 96040030 lhu r4,0x0030(r16) |Destination X 001759d0: 00021200 sll r2,r2,0x08 |Flag becomes elevation offset Elevation ? 001759d4: 00001812 mflo r3 |Max X * Y to spread 001759d8: 00431021 addu r2,r2,r3 | 001759dc: 00441021 addu r2,r2,r4 |Destination Tile ID Y*Max X + X + Elevation (0 or 0x100) 001759e0: a602001c sh r2,0x001c(r16) |Store ID of destination Tile 001759e4: 00021400 sll r2,r2,0x10 | 001759e8: 00021343 sra r2,r2,0x0d |Tile ID * 8 001759ec: 3c038019 lui r3,0x8019 | 001759f0: 2463f8cc addiu r3,r3,-0x0734 | 001759f4: 00431021 addu r2,r2,r3 |Destination data pointer 8018f8cc + Tile offset 001759f8: 8604001c lh r4,0x001c(r16) |Destination ID 001759fc: 3c038019 lui r3,0x8019 | 00175a00: 24632dd8 addiu r3,r3,0x2dd8 | 00175a04: ae020004 sw r2,0x0004(r16) |Store Pointer of destination Tile data 00175a08: 00041080 sll r2,r4,0x02 | 00175a0c: 00441021 addu r2,r2,r4 |Tile ID*5 00175a10: 8e040004 lw r4,0x0004(r16) |Destinaton data pointer 00175a14: 00431021 addu r2,r2,r3 |Destination grid data pointer 80192dd8 + Tile offset 00175a18: ae02000c sw r2,0x000c(r16) |Store Grid pointer 00175a1c: 90820002 lbu r2,0x0002(r4) |Destination Height 00175a20: 8e030004 lw r3,0x0004(r16) |Tile's data pointer 00175a24: 00021040 sll r2,r2,0x01 | 00175a28: a202004d sb r2,0x004d(r16) |Store Destination Height*2 (S-Pad 0x180) 00175a2c: 90620003 lbu r2,0x0003(r3) |Destination Halves + depth 00175a30: 8e030004 lw r3,0x0004(r16) |Destination data pointer 00175a34: 3042001f andi r2,r2,0x001f | 00175a38: a2020057 sb r2,0x0057(r16) |Store Destination Halves (S-Pad 0x180) 00175a3c: 90620004 lbu r2,0x0004(r3) |Destination Slope Type 00175a40: 00000000 nop | 00175a44: a2020059 sb r2,0x0059(r16) |Store Destination Slope Type (S-Pad 0x180) 00175a48: 8602001c lh r2,0x001c(r16) |Tile ID 00175a4c: 92030042 lbu r3,0x0042(r16) |Path Flag 00175a50: 00000000 nop | 00175a54: 10600026 beq r3,r0,0x00175af0 #If "Above Units" Path 00175a58: 00a28821 addu r17,r5,r2 |Destination pointer in S-Pad 0x200 --- Above Unit Path Section --- 00175a5c: 92220000 lbu r2,0x0000(r17) |Destination Flags 00175a60: 00000000 nop | 00175a64: 30420028 andi r2,r2,0x0028 | 00175a68: 10400104 beq r2,r0,0x00175e7c #If Flags 0x20 and 0x08 are OFF : Exit and return 0x01 00175a6c: 34020001 ori r2,r0,0x0001 | 00175a70: 8e02000c lw r2,0x000c(r16) |Destination grid pointer 00175a74: 86040030 lh r4,0x0030(r16) |Destination X (for jal) 00175a78: 90420002 lbu r2,0x0002(r2) |ID of Unit on destination Tile 00175a7c: 00000000 nop | 00175a80: a2020043 sb r2,0x0043(r16) |Store Unit ID in S-Pad 0x180 00175a84: 92030043 lbu r3,0x0043(r16) |Destination Unit ID 00175a88: 86050032 lh r5,0x0032(r16) |Destination Y (for jal) 00175a8c: 000310c0 sll r2,r3,0x03 | 00175a90: 00431023 subu r2,r2,r3 | 00175a94: 00461021 addu r2,r2,r6 |Pointer to Unit ID in Scratch-Pad 0x080 00175a98: 90420006 lbu r2,0x0006(r2) |Unit Height + Size 00175a9c: 92060045 lbu r6,0x0045(r16) |Destination Entry slope mod (for jal) 00175aa0: 2447ffff addiu r7,r2,-0x0001 |Unit Height + Size -
