- is there a way to randomize a flag activated/deactivated or wait time?
- i assume to change colorgrade you need to do it via a flag?
#lua cutscenes - a couple questions
formal stump
oh also can it loop?
copper jay
- This would be better explained with an example:
function onBegin()
math.randomseed(os.time()) -- This gives us a unique seed for the random number generator
flags = {"flag_a", "flag_b"} -- Declare our flags
index = math.random(1, #flags) -- Choose a random number between 1, and the number of flags.
flag = flags[index] -- use that number to get the flag
setFlag(flag, true) -- set that flag
end
ah okay
copper jay
- You would do this via calling C# code.
formal stump
i assume for wait time id do the same but replace setflag with wait and flags/variables/etc. with associated things

math.random is lua randomness, so not consistent
for purely visual stuff that's fine, but generally you should use celeste's own random system
copper jay
math.random is lua randomness, so not consistent
why would you want something random to be consistent?
formal stump
tas
copper jay
oh
copper jay
2) You would do this via calling C# code.
something like getRoom():SnapColorGrade("nameofcolorgrade")
wispy edge
no
copper jay
no
formal stump
oh okay
wispy edge
something like `getRoom():SnapColorGrade("nameofcolorgrade")`
or getRoom():NextColorGrade("name", fadespeed) if you want to fade smoothly
fossil stratus
why would you want something random to be consistent?
so that you don't annoy people who need the behaviour to be consistent 
wispy edge
do i have to put room name anywhere
no, getRoom() just gets the current room
formal stump
ah okay
wispy edge
also, how do i make it loop?
use a while loop with a wait() call in it. so like
oops enter
while true do
--stuff you want to check
wait()
end
ty!
wispy edge
wait() pauses the execution until the next frame (running an infinite loop in a single frame is a bad idea)
formal stump
how would i stop the loop on room exit? ik i need to replace the true but not sure what with
wispy edge
it does automatically. the cutscene is part of a cutscene entity in the room, so it will stop when you leave the room
wispy edge
also make sure to call
makeUnskippable()
enableRetry()
at the start of onBegin (assuming this isn't an actual cutscene)
wispy edge
actually you can just tick unskippable on the cutscene trigger I think
formal stump
so rn i have
`function onBegin()
makeUnskippable()
enableRetry()
while true do
math.randomseed(os.time())
index = math.random(8, 30)
wait(index)
getRoom():SnapColorGrade(“whoYellow”)
wait(.35)
getRoom():SnapColorGrade(“whograde”)
end
end`
is that good?
wispy edge
you don't want to seed the rng every loop, just do that once at the start
wispy edge
otherwise that seems sensible
formal stump
okay epic!
wispy edge
btw you can do ``` for code blocks instead of using single backticks for each line individually
formal stump
oh okay
wispy edge
you can even start the code block with ```lua to get syntax highlighting
wispy edge
```lua
while true do
--stuff you want to check
wait()
end
```
that's why stuff is colored here
formal stump
oh it doesnt appear like that on mobile
wispy edge
if you want a minuscule performance boost, you can do local level = getRoom() before the loop and then replace the getRoom() calls after that with level
it doesn't matter at all, I'm just a code style pedant 
formal stump
do i include the Assets part of the filename in the filename field in lonn?
wispy edge
uh I think so?
wispy edge
(I have never actually written a lua cutscene so I'm not 100% sure 
)
the wiki says so yeah
formal stump
oh yea just saw
