Animations overriding my attack animation in Godot 4?

Question

This is my first time programming with Godot, and I'm trying to include a sword attack animation. However, other animations such as jumping, idling, or walking are overriding the sword animation.

I tried using the await function to wait until the sword animation is finished, then set the 'attacking' variable to false. This just plays the first frame of the sword animation, then it's overrided by another animation. I'm using an animation player set with the name 'anim' to play these animations, I would appreciate it if someone could help with this as I have very little experience with godot. Below you can find my entire code for the player:

extends CharacterBody2D

const normalspeed = 400.0
const JUMP_VELOCITY = -600.0
var jump_count = 0
var dashing = false
var attacking = false
var dash_count = 0
var stamina = 100
var game_running = true
var totaldashcount = 0
var player_moving = false
var frontflipping = false
var health = 100

const cooldown=preload("res://Scripts/Cooldown.gd")

@onready var dash_cooldown=cooldown.new(2)

const dashspeed = 2500
const dashlength = 0.15

@onready var dash = $Dash

var gravity = ProjectSettings.get_setting("physics/2d/default_gravity") * 1.7

@onready var anim = get_node("AnimationPlayer")

Answer 1

You are setting attacking back to false every frame, right here:

func _physics_process(delta):
    
    player_moving = false
    attacking = false # <-----

And I do not see any await in your code.

You could read current_animation:

func _physics_process(delta):
    
    player_moving = false
    attacking = anim.current_animation == "Sword Attack"
