Remarks

Returns nil if no channel was found.

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

Example

local toFind = Channel.keyframe()
toFind.name = "myChannel"
track.colorA = toFind * mixedChannel
local foundChannel = track.colorA.find("myChannel")
foundChannel.addKey(0, 255)

valueAt(timing)

Description

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", Channel.constant(1000), Channel.constant(1), Channel.constant(0), Channel.constant(0))
log(saw.valueAt(500))
local keyChannel = Channel.keyframe()
track.colorA.addKey(1000, keyChannel.valueAt(1000))
track.colorA.addKey(2000, 0)
