ValueChannel

Remarks

Returns nil if no channel was found.

This method is useful to detect if you have previously created a channel for a property of a controller, which is a common need when working with note groups.

Example

local toFind = Channel.named("myChannel").keyframe()
local mixedChannel = Channel.noise(10, -1, 1)
track.colorA = toFind * mixedChannel

local foundChannel = track.colorA.find("myChannel")
foundChannel.addKey(0, 255)

---

valueAt(timing)

Descriptions

Calculate the value at a timing point.

Parameters

Name	Type	Description
timing	number	Timing point to calculate at

Return types

number

Remarks

The implementation of this method differs for each channel type.

Example

local saw = Channel.saw('so', 1000, 1, 0)
log(saw.valueAt(500))

local keyChannel = Channel.keyframe()

track.colorA.addKey(1000, keyChannel.valueAt(1000))
track.colorA.addKey(2000, 0)
