Lego Island World Database
From Just Solve the File Format Problem
Revision as of 04:30, 6 January 2017 by Hamhock666 (Talk | contribs)
The Lego Island World Database format is for a particular file in the Mindscape game Lego Island. This file stores all of the models and textures used in the game.
Format
// Documentation info
// struct groups[x] -> A data structure called groups that is repeated x number of times.
// uint32 -> An unsigned integer that is 32 bits in size.
// float32 -> a floating point number that is 32 bits in size.
// char[x] -> A string of characters that is x characters long.
// if (INDEX) == 1 -> If the index of the current data structure is 1 execute the following indented.
// SEEK 10 -> Seek to byte 10 in the binary file.
// SEEKREL -1 -> Seek 1 byte backwards in the binary file.
// MARKER HELLO -> A marker definition that can be accessed with GOTO HELLO.
// GOTO HELLO -> Go to the marker HELLO.
