Thank you for your help! How could one do this for the Scale of an Actor, or object? Cheers!

That will help me a lot

[@jasoncai4769]

Thx. It helps a lot.

[@kv7164]

this makes perfect sense

[@FitGameDeveloper]

"Timelines don't work in widget blueprints (they only work in the actor class)". That is all I needed to know, unfortunately.

[@Extrone]

can I change the value of a key frame on the timeline at runtime ?

I believe you can't use them in functions too

[@MathewWadsteinTutorials]

Yep that is a good point =) You can't use them in Functions just like you can't use a Delay node and I completely forgot a bout that!

[@byLovebird1]

@@MathewWadsteinTutorials But can you use them to update a variable with a lerp and the lerp result to update a variable inside a function?

[@kyleryan7258]

@@byLovebird1 There's no way to update the value of a variable inside a function unless you do it inside the function itself, given that a function is executed within the frame it is called (while timelines execute themselves every frame until completion). To get this effect you are describing though, you can have the timeline update the lerp variable and also call the function, thus every-time the function is called it will have the new updated value.

[@rifat.ahammed]

Great

[@TheAmoscokkie]

question : What does the value in the curve represent ?

[@muffininacup4060]

just a value that changes in time, what it does depends where you hook it up - it can be alpha in lerp node, or the value of emissive strenght as in the example here

[@chaotickreg7024]

Any value
