Defines the reference elapsed time offset within a single cycle of a Timeline at which the associated values will be set and at which the #action() function will be called. KeyFrames having time < 0s will be ignored by the Timeline.

The list of target variables and the desired values they should interpolate at the specified time of this KeyFrame. Commonly, KeyValues use a constant value, for example: values: x => 10 but can also use a non-constant value, such as: values: x => someVal + 5 KeyValue.value expressions are evaluated once before a Timeline is played. The results are saved and used for each play of the Timeline. For some Timelines, it is desirable for KeyValues to be re-evaluated and take on a different value for each run (or even during a run). The Timeline.evaluateKeyValues() function allows this.

Defines whether or not the #action() function can be skipped if the master timer gets behind and more than one Timeline cycles are skipped between time pulses. If true, only one call to the #action() function will occur for each time pulse, regardless of how many cycles have occured since the last time pulse was processed.
