how to get bullets to stop rotating with gun?

GMPY

I have a player character scene which contains a node2d with my gun sprite and other related node2ds. This gun node is scripted to rotate to look at the mouse. The node2d also has a node with a script to fire bullets, and fires bullets normally (enough), but once fired they are still affected by the rotation of the gun, and go wherever the mouse is pointing. I've read the Instancing with Signals page on the docs that explains how to fix this, but it didn't work for me. Namely, the bullets don't seem to retain the information about their velocity and angle, and just shoot straight to the side no matter what. Is this because the "player" that they use in the Docs is the root node, and my gun is a child of the root?(my player character). I don't know. Is there a way to have my gun node signal the World2d node that my player scene is instanced within so that the world can instance the bullets? To make matters worse, when I fire bullets, they are affected by the velocity of my player, going faster when I move right, and slower when I move left. I am in quite the pickle. Thanks in advance.

You should have a root Node that is not the player character. Then when you spawn bullets, they should be children on the root Node, not the player or the gun. I think that will fix it.

Also make sure your script isn't updating every physics/frame the bullets orientation by copying the players.

For my turret I wrote a "fire" function who waits for a node in order to feed the "dangerous" add_child function.

func fire(target:Vector2, force:float, parent:Node2D):
    var p = projectile.instance() 
    parent.add_child(p)
    # then give him his velocity

You can try to rewrite this in an even more flexible way. If "fire" waits for an already instancied and added node the turret will be able to do funny things like throwing enemies because the "fire" function can take any Node2D as argument.

Thanks for the help guys, I was able to finally fix all my problems with a bit of tinkering!

Oh, if you're not a programmer - it's going to be very difficult for you to do that. I spent a lot of time trying all the scripts and doing the same thing, but I still could not do it. Whoever I asked, no one knew how to do it. I decided to create a gun and took a long time to study all its features. I even looked at ballachy.com slats to get them done well in my gun. After I did everything, I couldn't figure out the functions because my scripts were programmed to do one thing, but it turned out to be something else. But I'm not changing anything, and I play as is.
