Config File
Macros way heavily on your soul after a while. For me, the routine
of going to source compiling and then running was a waste of time.
I needed a config file loader fast, so this is what I came up with.
It was on the fly and it works, what more can you ask for. And most
of the code not, all of it, is below.
#
# glAnts - original config.ini
# file, change at your own risk
#
# if you remove this file, the program
# will create another one with the defaults
# so removing this file can be a good thing
#
#
# Also of note, if the system finds an error
# it goes with the default variable
#
# FORMAT has to be [VARIABLE_NAME]=VALUE;
# oh yeah, add the 'f' tag for float
#
# [VARIABLE_NAME]=VALUEf;
#
# COMMENTS are '#'
#
# Remove the comments below are your own risk
# they basically just define the default values
# used, if you remove them then you wont know
# what good values will look like
#
# The only things that really need changing
# are:
#
# USE_ANT_ENGINE: take out the little ants
#
# MAX_FIRE_ANTS: max fighter ants
#
# MAX_BOTS: number of worker ants
#
# INITIAL_ANT_FOOD: the health of the fighter
# ants and the workers
# try 10,000 and they will never die
#
# Also, you may comment one of the variables
# and get the default once the program runs
#
[GLANTS CONFIG]
# los default is 14.0
[LINE_OF_SIGHT]=115.0f;
# Used with the ai, it attacks at any point given
# this radius
# default is 4.0
[ATTACK_RADIUS]=4.0f;
# The amount of damage a bullet will inflict
# the damage is reduced considerably
# at a greater distance and its impact
# is great at short distances
# try 5000, hehe
# default = 280
[BULLET_DAMAGE]=280.0f;
# defaut is 4.90

# You can get rid of the worker ant
# engine and just shoot stuff

# this point, the ai goes berzerk
# and he will move a little faster

# the time before an ant drops a pheromone
# default: 40

# the number of bullets

# this doesnt effect that much
