/* TODO: *******************************************

*****************************************************
|
||||||
|
|
||||||
|
make power ups keep moving to player if the field is turned off
|
||||||
|
|
||||||
|
levels 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
|
||||||
|
|
||||||
|
Find a diegetic way to see player damage (and or field meter too)
|
||||||
|
a health meter, like the field meter above player? (doesn't work with the field meter)
|
||||||
|
|
||||||
|
field power up effects
|
||||||
|
field allows player to hold and throw living mobs
|
||||||
|
|
||||||
|
mod power ups ideas
|
||||||
|
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 rainworld
|
||||||
|
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
|
||||||
|
|
||||||
|
track foot positions with velocity better as the player walks/crouch/runs
|
||||||
|
|
||||||
|
Boss ideas
|
||||||
|
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.
