|
||||
|
||||
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
|
||||
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)
|
||||
|
||||
Add field upgrade, and mod to a permanent display
|
||||
left side
|
||||
separate box below guns
|
||||
|
||||
|
||||
cap guns to 3
|
||||
can up the drop rate on guns, and lower ammo amount or drop rate
|
||||
cap mods to 2
|
||||
can up the drop rate a bit
|
||||
check if there are any double mod compatibility issues
|
||||
cap field to 1
|
||||
|
||||
what about no cap to mods?
|
||||
mods without caps can't have major negatives
|
||||
do I want to support a power ramping game play?
|
||||
more upgrades are OK as long as they change game play
|
||||
no flat damage, or flat defense buffs
|
||||
This makes skipping content a bad idea for the player
|
||||
Is that maybe good? No need to nerf content skipping buffs
|
||||
content skipping is a cool play style, but not core game play
|
||||
|
||||
|
||||
field power up effects
|
||||
field produces a whirlpool effect of force around player
|
||||
field allows player to hold and throw living mobs
|
||||
|
||||
Move mods, to power up object
|
||||
mods can be about more than the gun, defensive, traversal mods
|
||||
gun mod power ups
|
||||
bullet on mob damage effects
|
||||
add to the array mob.do new mob behaviors
|
||||
add a damage over time
|
||||
add a freeze
|
||||
fire a few smaller bullets
|
||||
killing a mob triggers: a spore bullet
|
||||
maybe you could replace the power method with a new one to get this to work
|
||||
negative mods for balancing
|
||||
self damage on fire
|
||||
knock back
|
||||
lower fire rate
|
||||
smaller bullets
|
||||
smaller explosions
|
||||
shorter lasting bullets
|
||||
|
||||
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.
|
||||
