Jump Pad script?

Hey guys!

I've been trying now for the last few hours to put together a script which when the 2D character collides with a box, the character will jump (much higher than a normal jump).

I am using the Platformer Character 2D script for my character movements.

I've only found people showing how to do it with the Character Movements script but when I try to integrate the way they did it with my Platformer Character 2D script it either doesn't work or completely crashed Unity haha.

So basically i'm looking or the easiest way to do this.

Thanks in Advance!
