How do I check joystick's applied position?

I’m using the gamepad extension and am wondering if there’s a way to set up the sensitivity with movement. Example, say I have an instant force of 5 when left joystick is pushed right. I want it to have 5 different stages though. Like if it’s pushed 20% it would be 1. 40% 2. And so on.

There is an expression for stick pressure which goes form 0-1. You could use that to multiply whatever you want max speed to be in your movement actions.
