So basically I was following a tutorial when suddenly found that the “NOT” node doesn’t work inside transitions rules.
In the video I show the Event Graph where I pick the boolean “is alive” from the character and promote to 2 booleans, “Is Alive” and “Is dead” with a not, everything ok for now.
Then go to the Anim Graph, where I have a death animation with a simple transition rule. If I use the boolean “Is dead”, works fine, character plays death animation when dies. But is I use “Is Alive” with a “NOT”, doesn’t work as spected and performs the death animation since beginning.
