How to link a parameter to a health value in unity?

I’ve been following the survival shooter tutorial and now I’m trying to introduce a heartbeat event as a parameter named “Health” as the players health goes under 40%

My script is bellow https://gist.github.com/anonymous/b65b9d72270bfdb7f300a5a7ca99d0c7

I think i’ve currently called the event but it’s just linking the “Health” paramiter value to the “Currenthealth”

At the moment you have it set to play every time the player takes damage while Health <= 40. If it is a looping sound you would only want it to play once, then adjust the parameter to change the sound of the event accordingly.

You can get a reference to a parameter from the event and then call setValue().
Here is an example using event->setParamaterValue().
