Code Snippets
#1

Following script can convert all .bam to .egg and then those .egg into .obj from specified folder.

import os

directory = ''

bam_models_list = []
egg_models_list = []
x_models_list = []

commands = '''\nFollowing commands are available:

    debug - enables debug
    setDir - allows you to set working directory for converter
    bam2egg - converts all .bam files to .egg in specified directory
    egg2bam - converts all .egg to .bam
    egg2obj - converts all .egg files to .obj in specified directory
    bam2obj - converts all .bam to .egg and then those to .obj
    x2egg - converts all .x to .egg
    exit - quits the program
