Moving Scale of Object

[Everynone]

• make the timeline track sinusoidal and set the timeline to loop (check the top row in the timeline editor)
• or create a custom event that fires on timeline finish and restarts the timeline
• or play the timeline forth an back
• or use Set Timer by Event to cyclically restart it

All of these should work well.

I’m a beginner so this is probably a very simple question:

I set up a lerp animation where an object’s scale gets bigger on begin overlap, and then when there is an end overlap, the “reverse” is activated, making the object smaller.

But now, I want to activate the get bigger and smaller autonomously–on awake, a lung-like object gets bigger for three seconds, and then smaller by itself, and then bigger again, etc. rhythmically.

How do I begin to do this with blueprint scripting? I looked up youtube videos on autonomously moving platforms, but none seem to quite get what I’m looking for.

Wow, thank you so much for this kind and thorough response!
These sound great, and I look forward to trying them out.

Just to give you an idea of what I mean:

Or like this, which is by far the simplest way imaginable:

This is an amazing answer. Thank you so much–I feel like I learned so much from your response. I didn’t know you could loop the timeline. Cheers!
