Hey! I am making a top down shooter game. And I want the gun from my player to face the mouse. When the mouse clicks I want the gun shots to look like the gunshots in this video while at the same time facing the mouse; https://www.youtube.com/watch?v=cjh35bEZLLc
Can anyone help? Thanks!

look_at is your friend, the mouse position you can get with the Viewport , the Look At Pointer demo has some smooth movements applied to that too.
You can look_at this tutorial for more detailed information on the basics of rotations (lerp and stuff like that)

For the shot, since shotguns tend to be instant and short range, you can cast a couple of rays from the shotgun to represent the pellets if is the way you want to apply damage and use a particle effect for visuals.
The other option is to instance bullets or create a triangle area if the damage is full area with a simple animation.
Hey thanks for the rotation towards mouse resources. Do you know of any tutorials that teaches the instant shooting with the rays?

No, it just occurred to me while thinking about the tools godot has for something like that xD
Never used rays yet (I’ve come from engines where rays are not a common tool) but they seem useful for many things.
I can think on something like:
You can enable all the rays when shot takes place (with code or AnimationPlayer for a delay) and check them one by one.
No need to check distance to calculate damage, all can do the same, the closer, the more rays hit a target.
Walls and front targets can block the ray so it nulls common area shot issues.
If you use a Gun class with bullets, the rays can be a non moving bullet (individual or in group), just instance, cast and dies.
As a con, invulnerability frames after hit can’t be applied instantly this way, you will have to delay it or control in some way.
