Question How do I access "Elapsed %" from the Timer node?

I am trying to create a script that uses the Timer node. Connecting the "Elapsed %" (or "Elapsed", for that matter) to anything returns this, or similar, error message:

"InvalidOperationException: The value of 'elapsedSeconds' on 'Timer#1a7e8...' cannot be fetched dynamically, it must be assigned."

This happened when I tried to connect Elapsed% directly to a Lerp node. I thought maybe seting a graph variable would work, but connecting "Elapsed %" to "Set Variable" returns the exact same error.

I'm attaching a screenshot of the graph in case it's relevant.



Unless I'm missing something, there seems to be no way to access the "Elapsed %". How do I do this? Alternatively, is there any way to get values between 0 and 1 over a number of seconds for a lerp function? What I'm trying to accomplish is theoretically pretty simple - I want alpha of an image to go from 0 to 1 linearly.

I have some rudimentary coding knowledge, but not much beyond basics - I wouldn't be using Visual Scripting otherwise.

There is already a thread about this issue, but it's two years old and doesn't contain an actual answer ( https://forum.unity.com/threads/what-is-wrong-in-this-graph.1057853/ ). And I assume the way visual scripting works may've changed in the interim.

EDIT: I managed to get around this by manually adding Delta Time to a float and dividing it by the original timer time (and not using the Timer node at all). But I'm still curious if it's possible to make "Elapsed %" work, since it'd make it possible to do in one node what I did in like, seven.

 

It means that you are trying to use the elapsed values in another flow. You have to simply assign the elapsed values to a variable and then use that new variable to get the elapsed value anywhere you need.

To put the elapsed values to a variable, use the tick flow and set the elapsed value to a variable while the Timer is running.

In other words, you must use the Timer's flow to set the var, not Update's.

 

It worked. It hadn't occurred to me to connect the assigning to the Tick output of the timer; thank you so much for your help, you probably saved me a lot of hassle down the road.
