You might have to share a screenshot of your events, since I don't know exactly why it isn't working. If the player is spawning the bullets just put Set Angle of Motion - Player.angle for the bullet right after. I can help more with a a screenshot.
I will say this though: You will not want to make this a big game. Construct's 3D is simply not good enough for full 3D games, so if you want to make big and fleshed out 3D games, I'd recommend other engines such as Unity and Godot.
