/* TODO: *******************************************
*****************************************************
add builds with combinations of gun, field and mobs
use the pull down menu
dynamically generate html about fields, guns and mods
add grid check to improve queries over large body arrays
something about broad phase
having trouble with this, might give up
gun: like drones, but fast moving and short lived
dies after doing damage
gun: Spirit Bomb (singularity)
use charge up like rail gun
electricity graphics like plasma torch
suck in nearby mobs, power ups?, blocks?
sucked in stuff increase size
uses energy
mod: auto pick up guns, heals, ammo
use the same rule for drones
maybe give some other bonus too?
rework junk bot
it's behavior is too unpredictable
range is unclear
having the bullets last long after doing dmg isn't fun
we want a fun gun that acts like a melee weapon
atmosphere levels
large rotating fan that the player has to move through
give the user a rest, between combat
low combat
nonaggressive mobs
one mob attacking the passive mobs
more graphics
Boss levels
boss grows and spilt, if you don't kill it fast
sensor that locks you in after you enter the boss room
boss that eats other mobs and gains stats from them
chance to spawn on any level (past level 5)
boss that knows how to shoot (player) bullets that collide with player
overwrite custom engine collision bullet mob function.
add a key that player picks up and needs to set on the exit door to open it
make power ups keep moving to player if the pickup field is turned off before they get picked up
not sure how to do this without adding a constant check
animate new level spawn by having the map aspects randomly fly into place
new map with repeating endlessness
get ideas from Manifold Garden game
if falling, get teleported above the map
I tried it, but had trouble getting the camera to adjust to the teleportation
this can apply to blocks mobs, and power ups as well
field power up effects
field allows player to hold and throw living mobs
mod power ups ideas
double jump
bullet on mob damage effects
add to the array mob.do new mob behaviors
add a damage over time
add a freeze
give mobs more animal-like behaviors
like rain world
give mobs something to do when they don't see player
explore map
eat power ups
drop power up (if killed after eating one)
mobs some times aren't aggressive
when low on life or after taking a large hit
mobs can fight each other
this might be hard to code
isolated mobs try to group up.
game mechanics
mechanics that support the physics engine
add rope/constraint
get ideas from game: limbo / inside
environmental hazards
laser
lava
button / switch
door
fizzler
moving platform
map zones
water
low friction ground
bouncy ground
