Paragon character shooting weapon

Ah, sorry.
Playing an animation you have for the current character is more direct, and can be done multiple ways.
The more “correct” way is to add it to the AnimBP for the character, but I’m a little busy to break that down at the moment.
(creating a state for it, setting up a flag to signal its use then playing the animation as any other in its own state in short)

The more direct way is to use a Montage.
Go into the AnimBP and double click to open the AnimGraph
Drag out of the state machine and type Slot… Connect that into the Output Pose

Now your AnimBP is ready to flow from current animation to a montage and back without breaking.

Find that shooting animation.
Right click and create a Montage of it.

Now you can cast to the AnimBP (if you’re going to do this often, get a reference to it and save it, changing if needed)
