I have learned the basics of blender and in my FPS (first Person Shooter) i have made everything succesfully so far. But, I cant find a way to make it so when i press Left click my gun shows a blast and shoots toward the aimer! If any of you out there know a way to do so Please reply!

normally to point towards the aimer you parent something so it always has the same rotation as the “aimer” (crosshair?) and points at it. showing a blast can be done different ways but try using a plane, set it to a texture and set it to “add”. Parent it like the object that shoots and turn it’s visiblity on and off or something like that.
