Dark_Jubei, if you know the starting and ending Z you want you can create a Timeline in your blueprint that animates a float value. You would then use this float value as the Z input for a “Make Vector” node. You would then use the “Set Actor Location” node to set your actor’s location. Note, you’ll have to trigger the “Play” execution pin of the Timeline to start the animation.
Alternately, if you don’t know the exact end Z, you could use the “Event Tick” event to change the Z value of the actor a little bit each tick using the “Add World Offset” node.
If you need more info on either of these approaches let us know.
