How can i make an animation starting the level?

totally, once you have your Matinee animation every-time you “die” you can call on the function to play again, the only thing you have to do is define this in a blueprint system as for that i cannot help you I’m not much of a programmer.

I assume you have your character controller set up for how it controls the pawn, next you will need to define what can cause death, how it handles it.

I could imagine that it would rag doll or hide the player on death, Teleport back to the starting location while hidden, Play the Animation from the Matinee and un-hide the player to begin again.

Your gonna have to Play some R’N’D with what will work.

this might help you in that direction
