help with animation please :(

Hiya, sorry perhaps i didn't explain the issue, basically i want a trigger or a replay even, that when pressing a certain key the character takes the rocket launcher from behind his chair and brings it around and infront of him, the problem is when i create the replay from the keyframes etc, the rocket launcher doesn't show it coming from in front or behind unless i have the play head on the record tab before or behind the replay itself 😞 im not sure if im doing something wrong or thats just a limitation perhaps i should try to animate it as a cycle layer?  When i play the animation manually via the recorder tab it plays fine although a little jerky.
