i’m following this web"Setting Up Character Movement" ,
and in the " Creating the Animation Blueprint => 8.From the MyBlueprint tab, navigate to the variables category, then drag and drop the Is Jumping variable on to the return pin of the Get Pressed Jump node.
The “Get Pressed Jump” node can’t return "true " anyway .
I try other bad way to make “is jump be true” ,it can play jump animate.
And in the Result video of this web the jump animate is not right
Of course it can. It is automatically set by Jump() and StopJumping().
Can you try this setup in your character and do tell if it works?
I’m succsess get “true” in character blueprints by using “get pressed jump”.But in the AnimBlueprint t by using “get pressed jump”，not get “true”. 
I make a variables “areJump” to get the “get pressed jump” value in character blueprints,then give it in AnimBlueprint ,the jump animate success play . Direct use “get pressed jump” in AnimBlueprint （like what Tutorial do）not success,it full of “false” in screen 
.
