Animation not transitioning Unity

Question

so I’m kind of new to Unity and I’m making a top down 2D shooting game. I’m trying to make my character play the death animation when he dies but for some reason it doesn’t transition. I tried using the Float condition and Bool condition in the animator but both don’t work when I set the float/bool to 1/true with animator.SetBool/SetFloat. The strangest thing is that if even when I put the bool to true or float to 1 in the animator it doesn’t work either and doesn’t change the animation. I’m probably overlooking 1 little thing so I hope you can explain. (btw my code is kinda spaghetti i know)

Animator component on player object: image Script (although maybe not really necessary because it doesn’t work in the editor either)
