Don't worry , Your Awesome Game Dev Super-Whiteclaws is here to help !
tip of today !
You can do that in z easy steps !
First of all , your gun need to be defaulted to the angle of the player ( By Default , the gun nozle needs to point toward the player view direction )
Next , Add the following event to your game ( - = Sub-events , * = Action)
* Set Mirrored to Not Mirrored
* Set Mirrored to Mirrored
And you are done !
P.S. The Mirrored action can be found in the Gun Actions Section
