Returns a `Datatype.NumberSequence` with the start and end values set to
the provided `n`.

  ```lua
  local numberSequence = NumberSequence.new(n)
  -- Equivalent to
  local numberSequence = NumberSequence.new{
      NumberSequenceKeypoint.new(0, n),
      NumberSequenceKeypoint.new(1, n)
  }
  ```

NumberSequence.new

Returns a `Datatype.NumberSequence` with the start and end values set to the
provided `n`.

Returns a `Datatype.NumberSequence` of two keypoints with `n0` as the start value
and `n1` as the end value.

  ```lua
  local numberSequence = NumberSequence.new(n0, n1)
  -- Equivalent to
  local numberSequence = NumberSequence.new{
      NumberSequenceKeypoint.new(0, n0),
      NumberSequenceKeypoint.new(1, n1)
  }
  ```

Returns a `Datatype.NumberSequence` of two keypoints with `n0` as the start value
and `n1` as the end value.

Returns a `Datatype.NumberSequence` from an array of
`Datatype.NumberSequenceKeypoint|NumberSequenceKeypoints`. The keypoints
must be provided in a non-descending time value order. At least two keypoints must
be provided, and they must have a time value of `0` (first) and `1`
(last).

  ```lua
  local numberSequence = NumberSequence.new{
      NumberSequenceKeypoint.new(0, 0),
      NumberSequenceKeypoint.new(0.5, 0.5, 0.25),
      NumberSequenceKeypoint.new(1, 1)
  }
  ```

Keypoints

Returns a `Datatype.NumberSequence` from an array of
`Datatype.NumberSequenceKeypoint|NumberSequenceKeypoints`.

The `Datatype.NumberSequence` data type represents a series of number values
from `0` to `1`. The number values are expressed using the
`Datatype.NumberSequenceKeypoint` type. This type is used in properties such
as `Class.ParticleEmitter.Size` and `Class.Beam.Transparency` to define a
numerical change over time.

#### Equality

Two `Datatype.NumberSequence` objects are equivalent only if the values of
their `Datatype.NumberSequenceKeypoint` are equivalent, even if both would
result in similar graphs.

#### Evaluation

The `Datatype.NumberSequence` type does not have a built-in method for getting
the value at a certain time/point because keypoints can have random envelopes.
However, assuming the envelope values of your keypoints are all `0`, you can
use the following function to evaluate at a specific time.

  ```lua
  local function evalNumberSequence(sequence: NumberSequence, time: number)
      -- If time is 0 or 1, return the first or last value respectively
      if time == 0 then
          return sequence.Keypoints[1].Value
      elseif time == 1 then
          return sequence.Keypoints[#sequence.Keypoints].Value
      end

      -- Otherwise, step through each sequential pair of keypoints
      for i = 1, #sequence.Keypoints - 1 do
          local currKeypoint = sequence.Keypoints[i]
          local nextKeypoint = sequence.Keypoints[i + 1]
          if time >= currKeypoint.Time and time < nextKeypoint.Time then
              -- Calculate how far alpha lies between the points
              local alpha = (time - currKeypoint.Time) / (nextKeypoint.Time - currKeypoint.Time)
              -- Return the value between the points using alpha
              return currKeypoint.Value + (nextKeypoint.Value - currKeypoint.Value) * alpha
          end
      end
  end

  local numberSequence = NumberSequence.new{
      NumberSequenceKeypoint.new(0, 0),
      NumberSequenceKeypoint.new(0.5, 1),
      NumberSequenceKeypoint.new(1, 0),
  }

  print(evalNumberSequence(numberSequence, 0.65))  --> 0.7
  ```


NumberSequence

An array containing `Datatype.NumberSequenceKeypoint` values for the
`Datatype.NumberSequence`.


NumberSequence.Keypoints

An array of `Datatype.NumberSequenceKeypoint` values in ascending order.


A series of floats across a period of time.


Default Value: {defaultValueStart}{defaultValueEnd}

This function returns immediately if possible, but can yield the thread that called it until it can return a value.

This member doesn’t appear in the object browser and is not intended for widespread use.

This member is only accessible only through the command bar. Attempting to access this member from scripts causes an error.

This function can’t pause the Lua thread that called it.

Attempting to access this member in scripts causes an error. You might be able to access this member from Roblox Studio's property window.

This member doesn’t appear in Roblox Studio’s Object Browser.

You can’t create an instance of this class with the Instance.new constructor.

Roblox does not replicate this member across its server-client boundary.

Lua code can’t access this member. You might be able to change its value from the property window in Roblox Studio.

This object’s replication behavior is dependent on the player who owns it.

This member is accessible only through the command bar and plugins only. Attempting to access this member from scripts causes an error.

This property is read-only and is safe to read in unsynchronized threads. Attempting to write to it causes an error.

This member is read only. Attempting to write to this member causes an error.

This member is accessible only in CoreScripts.

Only Roblox CoreScripts can access this member, and it isn’t usable by Players.

You can read and write to this property safely from multiple threads.

This class is a top-level singleton. Retrieve an instance of this class with the GetService function.

Multiple threads can potentially write to this property, so it’s unsafe to read from unsynchronized threads.

This function pauses the Lua thread that called it until it returns a result. This doesn’t interrupt other scripts.
