(Noob) How do I use delta time to make my actor move up and down?

I am trying to get an object (a banana) to move up and down constantly throughout the duration of the game. This is my current blueprint. Can someone tell me why it doesn’t work and how to fix the issue? Currently it’s just having a spasm on the spot while rotating. Thanks

start by deleting the tick node.

begin play → timeline -1 to 1 to -1 looping → set actor location set the z value to the timeline value * 600.

or you could just use the ‘interp to movement’ component then you wouldn’t need any nodes.
or you could do this in the material graph with world position offset.

You could easily do this using the sequencer. Check out video #8 in the link below for an example of how to do this.
