How Make animation custom

Hello, I made my animation on blockbench and unfortunately I can't put them on Mc Creator and it only works under certain conditions.

I want to make for example my death animation when he dies but when I make the condition if the monster is alive it makes the death animation.

I don't really understand how it works with conditions.

I did something silly like if the player taps, he gets an animation when he taps us, but he still gets the death animation.
