Unreal Engine Blueprints Using Timelines for Animation 2

Question 1

What happens to a Timeline node when its owning Actor is destroyed while the Timeline is still playing?

Accepted Answer

The Timeline stops automatically because the Actor is gone

Answer

When an Actor is destroyed, all its components and Blueprint logic, including active Timelines, are cleaned up automatically.

Question 2

Which Timeline output pin fires only once when the Timeline finishes playing to its end?

Accepted Answer

Finished

Answer

The 'Finished' execution pin fires a single time when the Timeline reaches the end of its duration.

Question 3

How do you make a Timeline play at double speed without changing the curve itself?

Accepted Answer

Call 'Set Play Rate' with a value of 2.0

Answer

'Set Play Rate' on the Timeline node allows you to scale playback speed dynamically at runtime.

Question 4

In a Timeline's curve editor, what does a key's tangent control?

Accepted Answer

The easing and interpolation shape between keyframes

Answer

Tangent handles on curve keys determine how the value interpolates (eases in/out) between adjacent keyframes.

Question 5

Which node would you use to find out the current playback position (in seconds) of a running Timeline?

Accepted Answer

Get Playback Position

Answer

'Get Playback Position' returns the current time in seconds within the Timeline's duration.
