move player by float of another bp

Hi
how to push the player forward using the float value of another blueprint?
Thanks

The basic issue you are struggling with is how to get a reference to the player char from the ocean and when to trigger it.
There are many ways to approach and solve this.

For example, add a box collision to the ocean. This enables OnHit event that provides the other object that was hit. This other object can be cast to your player char.

Best to watch a few of the intro videos on YouTube.

How to move the player. The function gets called by event graph but the player is not moving.
Thanks
