Blend Tree Dash Animation

Hey Guys,

Quick question I am sure you guys can answer. I am quite new to Unity and I am just now taking a stab at the animator

Currently my Animator is very basic and consists of three blend trees:
1) Idle
2) Running
3) Dashing

I have them all setup to play the animation relative to my mouse position (Top down 2D Shooter... think Enter the Gungeon Style...in fact I am using their sprites as placeholders)

So far everything is working fine but I am having a problem with my Dashing blend tree. My Dash is set to go in the direction of my movement through a script (which is working fine), but my dash animation appears to be tied to my mouse position.

That is problem 1. How can I make the animation play in the direction of movement rather than my mouse position?

Problem 2 I am having, is as I am using a blend tree for the dashing animation, if I move my mouse during the animation, the animation changes relative to my mouse position. I do have the transition into the Dashing animation set to play full which is working fine, but the animation itself isn't behaving the way I want (movement direction)

I'm wondering if I should be using some type of directional float parameter or something?

here are some screen shots of my animator

EDIT:

Fixed this myself by declaring new animation parameters within my dash script and using those for my blend tree

 

Thank you for the reply. Sorry I was busy with work but here is a gif of the issue. Notice how even if I move my mouse during that animation it rotates and plays frames from the other directions mid roll

Notice if I aim the gun in the direction of the roll it looks fine but as soon as I aim in a different direction it changes my orientation

I simply want the animation to play in my movement direction, and for it to fully complete before resuming
