Cannot subtract from NumberSequence

Help and Feedback Scripting Support
#1

I’m using for loops for this.
I’m currently trying to make a more efficient way of fading transparency without TweenService.

Unfortunately I stumbed across this error:

This is the problematic line:

This error only pops up when I add - behind =

Here’s the for loop part of the script that is not functioning, everything else is fine.

Any way I can fix this…?

I suggest looking at the evalNS function:

#3 
for i = 1, 0, -0.25 do
    Lens.Transparency = i
    light.Transparency = NumberSequence.new(i, 1)
    spotLight.Brightness += 2.5
    task.wait()
end

or

local currentValue = light.Transparency.Keypoints[1].Value
light.Transparency = NumberSequence.new(currentValue - 0.25, 1)

also make sure to benchmark because tweenservice is already efficient so you might not be saving any performance by doing this

#4

Running TweenService on server is not a good thing to do as far as I know…

Let me try the code first although.

#5

Running the tween service on the server side

Or

Setting a instance property many times on the server side

Have the same negative effect of having to send the instant properties over the network to all the clients multiple times

#6

Running TweenService on the server is all fine. :slight_smile:

That is not to say, that you should overdo them.

Hi!

I would suggest that you keep doing tweens. But if you insist on sticking to your work-around method, then I would suggest this for the beam:

Fixture.Head.Beam.Light.Transparency = NumberSecuence.new((.25*5)-(.25*i),1) -- I tried to adapt the method to your for-loop, which right now loops through 5 times.
