Randomizing attacks

So I'm looking to add a bit more randomness to my boss fights when it comes to attacks happening at certain points of their health. I'd like to build a boss that can have certain attacks fire off in different orders each time you face it.
Basically for example at 500 lp the room will have fireballs fall down from the ceiling above, now if you are on your second or third try of the boss you would have figured out the pattern of which they fall and where. I want to make it so when it triggers to fall from the ceiling they will launch down in a different order by using a random check and based on that check activate a particular spawner.
This part I'm able to get down pretty easy using this script
Code: Select all
function setatta()
local h = 1
local r = math.random()
if r < 0.3 then
spawner_9.controller:activate()
elseif r < 0.6 then
spawner_10.controller:activate()
else
spawner_11.controller:activate()
end
end
But could I use this random roll code to make it so the phases are randomised? Making it so each time you fight the boss the order of the special attacks are different, or maybe even making it so there are 5 total things that could happen and it runs 3 of them. Of course I would need some way of checking to see if it already ran(wouldn't want them to run a second time(or depending on the attack you would)).
So yea just looking for some feedback and help on it, do you think it could work using that code or would another one be better to use?

Perhaps a table of spawner IDs, where you randomly pick one key to use; remove it, then randomly pick another ~until there aren't any more.

Could you put in an example of how to do that?

An example:
Call the script from the console to see the output.
Code: Select all
print(math.random(1000), "unseeded ~random")
function randomize()
local seed1 = spawn("base_floor_decoration").id
local seed2 = spawn("base_floor_decoration").id
local seed = tonumber(seed1) * tonumber(seed2)
math.randomseed(seed)
findEntity(seed1):destroyDelayed()
findEntity(seed2):destroyDelayed()
print(seed, "seeded random; (the one we use).")
end
randomize()
function randomizedEffects()
local effect = {}
effect.spawnerIDs = {
"spawner_1",
"spawner_2",
"spawner_3",
"spawner_4",
"spawner_5",
"spawner_6",
"spawner_7",
"spawner_8",
"spawner_9",
"spawner_10",
"spawner_11",
"spawner_12",
"spawner_13",
"spawner_14",
"spawner_15",
"spawner_16",
"spawner_17",
"spawner_18",
"spawner_19",
"spawner_20",
}
effect.randomized = {}
for x = #effect.spawnerIDs, 1, -1 do
local id = math.random(x)
table.insert(effect.randomized, effect.spawnerIDs[id])
table.remove(effect.spawnerIDs, id)
end
for x = 1, #effect.randomized do
print(effect.randomized[x])
end
end
*Note: The randomize function is a bit of an experiment; I've not actually used it before in a serious map... It just occurred as an odd thought to try using a generated ID as the seed. It seems to work fairly well, so far. I'd be interested in learning of any downsides to this.
Experimental alternate version that picks two at a time, instead of one:
Code: Select all
print(math.random(1000), "unseeded ~random")
function randomize()
local seed1 = spawn("base_floor_decoration").id
local seed2 = spawn("base_floor_decoration").id
local seed = tonumber(seed1) * tonumber(seed2)
math.randomseed(seed)
findEntity(seed1):destroyDelayed()
findEntity(seed2):destroyDelayed()
print(seed, "seeded random; (the one we use).")
end
randomize()
function randomizedEffects()
local effect = {}
effect.spawnerIDs = {
"spawner_1",
"spawner_2",
"spawner_3",
"spawner_4",
"spawner_5",
"spawner_6",
"spawner_7",
"spawner_8",
"spawner_9",
"spawner_10",
"spawner_11",
"spawner_12",
"spawner_13",
"spawner_14",
"spawner_15",
"spawner_16",
"spawner_17",
"spawner_18",
"spawner_19",
"spawner_20",
}
effect.randomized = {}
for x = #effect.spawnerIDs, 1, -2 do
local id = math.random(x)
local id2 = math.random(x)
for x = 1, 999 do --ha!
if id ~= id2 then
break
end
id2 = math.random(x)
end
table.insert(effect.randomized, effect.spawnerIDs[id])
table.remove(effect.spawnerIDs, id)
table.insert(effect.randomized, effect.spawnerIDs[id2])
table.remove(effect.spawnerIDs, id2)
end
for x = 1, #effect.randomized do
print(effect.randomized[x])
end
end
