The AF files contain all the information related to HARs; sprites, key-combos, projectile sprites, base damage, etc. The format is not entirely understood but a large portion has been dissected and understood. All AF files are broken up into the following sections:
Fighter Header
This contains the basic data about the HAR. Unmodified speeds, endurance, power, etc.
| HAR Number | 1 WORD | Must be the same number as in the filename eg: FIGHTR1.AF |
| Unknown Data | 3 bytes | ? |
| Endurance | 3 bytes | Max is 2,143,755. Above or below that results in permanantly stunned state. |
| Unknown Data | 1 byte | ? |
| Power | 1 WORD | Damage Resistance, max is 8717. |
| Forward Speed | 1 signed DWORD | Speed at which the HAR moves towards opponent |
| Backward Speed | 1 signed DWORD | Speed at which HAR retreats from opponent |
| Upward Speed | 1 signed DWORD | Initial jump speed, this should be negative |
| Downward Speed | 1 signed DWORD | How quickly the HAR falls while being airborne, should be positive |
| Unknown Data | 1 WORD | ? |
Animation
Animation Header
| Animation Number | 1 BYTES | Unique Identifier for animation |
| Unknown Data | 8 BYTES | Zero padding? |
| Overlay Amount | 1 WORD | TODO |
| Frame Count | 1 BYTE | How many frames in this animation |
| Overlay Table | N DWORDS | TODO |
Animation String Header
| String Length | 1 DWORD | Length of the string |
| String | N BYTES | Animation string |
| Unknown Data | 1 BYTE | ? |
| Number of Extra Strings | 1 BYTE | How many other animation strings there are |
Extra Animation Strings
| String Length | 1 WORD | Length of string |
| String | N BYTES | Extra Animation String |
| Unknown Data | 1 BYTE | ? |
Sprites
There then follow N sprites, where N is the frame count specified in the animation header.
Sprite Header
| Length | 1 WORD | Length of sprite |
| X Position | 1 SIGNED WORD | TODO |
| Y Position | 1 SIGNED WORD | TODO |
| Width | 1 WORD | Width of the sprite, in pixels |
| Height | 1 WORD | Height of the sprite, in pixels |
| Mirrored | 1 BYTE | Is the sprite Mirrored |
If the sprite's mirrored value is non zero, the sprite data appears elsewhere and the sprite data is fetched from the sprite whose index value is the current's sprite's mirrored value.
Sprite Data
If the sprite is not mirrored, Length bytes of sprite data follow. The sprite data is decoded thusly:
- Initalize X and Y to 0
- Read 1 WORD as P
- Modulus P by 4 to get OPCODE
- Integer divide P by 4 to get DATA
- Compare the OPCODE against the following and take that action
- Set X to DATA
- While DATA is greater than 0
- Read 1 BYTE
- Store that byte as the pixel at X,Y in the sprite
- Increment X
- Decrement DATA
- Set Y to DATA
- End of sprite data
The first 21 bytes of the animation footer have an unknown purpose. Some possiblities are listed.
| Unknown 1 | 1 BYTE | |
| Unknown 2 | 1 BYTE | |
| Unknown 3 | 1 BYTE | Seems to be related to airborne attacks, possibly constraints for positioning (near wall, etc) |
| Unknown 4 | 1 BYTE | |
| Unknown 5 | 1 BYTE | |
| Unknown 6 | 1 BYTE | |
| Unknown 7 | 1 BYTE | |
| Unknown 8 | 1 BYTE | |
| Unknown 9 | 1 BYTE | |
| Unknown 10 | 1 BYTE | |
| Unknown 11 | 1 BYTE | |
| Unknown 12 | 1 BYTE | |
| Unknown 13 | 1 BYTE | Next animation to play? |
| Unknown 14 | 1 BYTE | |
| Unknown 15 | 1 BYTE | Animation categories |
| Unknown 16 | 1 BYTE | Stamina damage? |
| Unknown 17 | 1 BYTE | Seems to be related to throws, maybe velocity of victim? |
| Unknown 18 | 1 BYTE | Damage (Value divided by 2.0) |
| Unknown 19 | 1 BYTE | |
| Unknown 20 | 1 BYTE | |
| Unknown 21 | 1 BYTE | |
| Move String | 21 BYTES | Move String |
| Footer String Length | 1 WORD | Length of footer string |
| Footer String Length | N BYTES | Footer string |
