I want the player to be able to shrink a sphere while they are staying on it and have it reset on trigger leave. How can I accomplish this?
#How do I use transform scale in Visual scripting?
mellow fable
So this is supposed to work?
mellow fable
Is onTriggerStay updating every frame?
fallen fossil
no, but Timer makes its own little routine
ive never used this node, but i think this is how it works
peak ocean
Dont use local scale unless its a child of a parent object
fallen fossil
yeah, wont suggest copying my graph, but the pieces are there
mellow fable
Dont use local scale unless its a child of a parent object
Oh mb
fallen fossil
but tbh i would use animation to do this, unless your brief specifically says you have to transform with code
mellow fable
So wait what am I supposed to use then
fallen fossil
well the key takeaway above is how the timer node works
do whatever you want with it though
in that example it goes for 1 sec
and you can use the % as 0 to 1 value for your lerp
mellow fable
Oh I see
fallen fossil
i cant say for sure what you will plug it into
but yeah I would use animation for this, and set boolean on the animator
peak ocean
Use remaining % because that goes from 1 to 0.
Multiply that with get scale and that shrinks object to 0.
fallen fossil
See if this video inspires a solution for you
peak ocean
Use remaining % because that goes from 1 to 0.
Multiply that with get scale and...
If you want to limit not going to 0, you can use a clamp node that connects remaining % as input.
And go min 0.5 and max 1.
So it stays at half the size.
There's more ways to do this btw.
mellow fable
Something like this?
peak ocean
Animation is like the easiest and has more control over that behavior. But if you need to do it via coding well here's one way
peak ocean
Something like this?
But thats not the node? Hmm it needs the middle to say "this". Not 0,0,0
mellow fable
Oh
fallen fossil
I'll wait till you get success with this before elaborating slightly on the anim approach, cos for your paper it is probably better to learn the code approach anyway
fallen fossil
no lossy scale?
fallen fossil
wow i also cant see SetLossyScale
mellow fable
oh its only getLossyScale
fallen fossil
you do run into that on occasion with UVS, it has most things but not all things
mellow fable
So are there any alternative scales to use?
fallen fossil
local is probably fine, just be aware it will be relative to its parent
if it has no parent it will just use global/lossy
mellow fable
Oh I don't think it has one
peak ocean
you do run into that on occasion with UVS, it has most things but not all things
Names of the node. Unchecking human naming helps 120%!
fallen fossil
yeah, can confirm, in this case UVS just has no setter for lossy
mellow fable
I think I'm missing something here
fallen fossil
one thing might be strange there
its always multiplying by its current scale
you probably want a fixed max scale value to multiply by instead
fallen fossil
run the numbers for a moment, 90% of 1 is .9, 80% of 1 is .8, etc etc
mellow fable
Yea nothing is happening when I touch the sphere
fallen fossil
but 90% of current scale would be... .9, and then on the next frame it will be 80%, but not 80% of initial scale, 80% of current scale, which will actually be 80% of .9, this will cause a sortof exponential effect
mellow fable
This is what I did btw
fallen fossil
and you confirm your sphere is set to trigger? and that 1 of the 2 colliders has a non kinematic rigidbody?
fallen fossil
physX is good but with game physics we have to always assume a margin of error
it's possibly that because there are 2 colliders with identical radius, overlap never happens
the first collider there might be blocking you from overlapping with the trigger
mellow fable
Thats a good point but nothing really changed once I fixed it
0.6 radius for trigger collider
fallen fossil
cant say for sure though, you will generally find consistent tests wont yield consistent results with physics lol
this is partly because of framerate etc
mellow fable
Oof
fallen fossil
but yeah it should work what you have
mellow fable
What about player
fallen fossil
does player have a rigidbody?
mellow fable
Maybe something wrong with it?
Good question actually lol, I'm using firstPersonStarter for this assignment because that was what was instructed
fallen fossil
i cant remember but i used to use a downloaded asset for teaching classes and it came with a CharacterController version, as well as a Rigidbody version
mellow fable
This is what I was given
fallen fossil
iirc there is some additional steps to take if you are using CC
mellow fable
Oh I think I am
fallen fossil
Ah, CharacterController
check over the docs page for Enter
https://docs.unity3d.com/ScriptReference/Collider.OnTriggerEnter.html
They've actually changed their docs since last I saw
it used to explicitly say one of the 2 colliders has to be a non-kinematic rigidbody, now it just "implies it" lol
mellow fable
It's not saying if its possible to make it trigger but the docs says there are messages associated wtih Character Controller 🙃
fallen fossil
you need OnControllerColliderHit apparently
mellow fable
Really?
fallen fossil
fallen fossil
i haven't used CC for years lol, someone else might better guide there
mellow fable
Imma just try replcing the event and see what happens
fallen fossil
how on earth do ppl get enter/exit events from this though?
mellow fable
So this didn't in fact work
fallen fossil
Hopefully someone else can weigh in here, it's been too long since I last touched CC
mellow fable
Honestly I might just reuse the code from the moving platform and use it for shrinking instead, I'll just take whatever grade atp 🙏
fallen fossil
Trust Google AI at your discretion lol
mellow fable
With what isTrigger property 😭 It doens't even exist
fallen fossil
it might mean for the collider attached to the same object as charactercontroller
or it is AI and it means nothing at all lol
fallen fossil
See if this video inspires a solution for you
https://www.youtube.com/watch?v=t...
btw, if you ever did offload the scale transitions to animation, your UVS graph becomes this... or whatever the characterController equivalent to that is
i abandoned CC years ago because working with these exact things is really tedious
Rigidbody has its own problems of course, but generally I prefer solving those than CC's problems
mellow fable
Yea its really starting to show
Honestly at this point I might just reuse the other code and repurpose for scale, thank you so much for your help otherwise ❤️
fallen fossil
for sure, hopefully someone else can shed light on the CC approach too in the meantime
try just dropping a kinematic rigidbody on your character controller lol
i dont think you have to add a collider to character, the characterController itself is already one
peak ocean
its always multiplying by its current scale
Its true sorry wasnt paying much attention 🤪 flu got my brain full of mucus
peak ocean
one thing might be strange there
Can be Float 1 multiplied by cooldown %
peak ocean
able to shrink a sphere while they are staying on it and have it reset on trigger leave.
OH! didnt read this... I'll make a graph tomorrow when im on my computer and show you how it can be done. 2x ways: via visual script and via animation (that also goes into uVS)
Sorry - i dont work on sundays 😛
mighty birch
So this didn't in fact work
Is this one the Character? because i imagine you need on controller collider hit would need to be on the GameObject with the character controller. I have not used Character controller but just seems like that
Then you could use a custom event on the Sphere to tell it to shrink but I imagine that you still have no way of checking on exit
peak ocean
no, but Timer makes its own little routine
Timer and cooldown are my favorites. I'll soon show how this can be done.
@mellow fable would help if you an illustration because "player to be able to shrink a sphere while they are staying on it"
That means..
-
player is close?
-
Player steps on it?
So a quick draw helps
