[SOLVED]How can I stop my character jump when finished my character's Energy is NULL ?

Hi everyone ! I’m new to unreal engine,therefore I’m trying to learn on tutorials of UnrealEngine 4 ( here is : https://docs.unrealengine.com/en-US/…UMG/QuickStart )

I completed this tutorial,and then an idea came to mind,I want to stop my character’s jump when finished my character’s energy bar is NULL.
But I don’t know how can I make this,That’s why I wanted ask this to you.
I’m waiting for your help,thanks.

Do a branch on the input for jump. drag your energy variable out as a get, drag off its pin and type in ==, drag off that pin and type in not, connect that pin to the branch. simple Boolean operation.
it goes like this:
IF(branch node) energy=zero(NOT(anything other than zero)) trigger true and do the jump, if energy = 0 trigger false and do nothing

Thank for help ixicalibur.
