Bin file structure

AGG file is an archive which contains multiple files. Bin files contain information related to displaying images (sprites) on screen.

Monster/creature animation bin file starts from short name of the creature ending by frm. For example, goblnfrm.bin. The file name length is 12 characters. The size of this file is always 821 bytes.

Creature animation frames are divided by sections. Each section could have up to 16 frames.

• Byte 0 : always 0x01 (magic value?)
• Bytes 1 - 3 : some creature related info ?
• Byte 4 : always 0xFF
• Bytes 7 - 116 : X-axis offset of frame for first 7 animation sections (16 values/bytes per section)
• Bytes 117 - 136 : ???
• Bytes 137 - 152 : 4 bytes (unsigned int) values of frame frequency in ms (???). Eg. 350, 1000, 750.
• Bytes 153 - 243 : ???
• Bytes 244 - 276 : amount of frames per each animation frame section (34 values in total)
• Bytes 277 - 820 : sequence of frame IDs for each animation section (34 sections). Only values which not equal to 0xFF are used in animation

Animation frame sections:

1. start flying
2. static/selection frame (?)
3. continuous movement or fly when a creature moves for long distance (?)
