Attack and Idle animations not playing

Recently started to attempt 1.20.1 modding, in registering idle, walk and attack animations in the mob entity class i've run into two issues:

a) idle and walk animations seem to play simultaneously  + the mob itself does not seem to walk

	private static final
	EntityDataAccessor<Boolean> ATTACKING = SynchedEntityData.defineId(MugaEntity.class, EntityDataSerializers.BOOLEAN);
	public MugaEntity(EntityType<? extends Monster > pEntityType, Level pLevel) { super(pEntityType, pLevel); }
	public final AnimationState idleAnimationState = new AnimationState(); private int idleAnimationTimeout = 1; 
    public final AnimationState attackAnimationState = new AnimationState();
	public int attackAnimationTimeout = 0;
    @Override public void tick() 
    { super.tick(); if(this.level().isClientSide()) { setupAnimationStates(); 
    } 
    } private void setupAnimationStates () { if(this.idleAnimationTimeout <= 0) { 
    this.idleAnimationTimeout = this.random.nextInt(30) + 60; 
    this.idleAnimationState.start(this.tickCount); 
    } else { 
    --this.idleAnimationTimeout; 
    } 
    if (this.isAttacking() && attackAnimationTimeout <= 0 ) 
    { attackAnimationTimeout = 20; 
    attackAnimationState.start(this.tickCount); 
    } else { 
    --this.attackAnimationTimeout; 
    } 
    if(this.isAttacking()) { 
    attackAnimationState.stop(); 
    } 
    } 
    @Override protected void updateWalkAnimation(float pPartialTick) { 
    float f; 
    if(this.getPose() == Pose.STANDING) { 
    f=Math.min(pPartialTick * 3.0F, 1.0F); 
    } else { 
    f= 0.0F; 
    } 
    this.walkAnimation.update(f, 0.2F);
    } 
    @Override protected void defineSynchedData() { 
    super.defineSynchedData(); 
    this.entityData.define(ATTACKING, false); 
    } 
    public void setAttacking(boolean attacking) { 
    this.entityData.set(ATTACKING, attacking); 
    } 
    public boolean isAttacking() { 
    return this.entityData.get(ATTACKING); 
    }
	

b) the attack animation is never played on attack, despite being registered 

	@Override
	public void setupAnim(Entity entity, float limbSwing, float limbSwingAmount, float ageInTicks, float netHeadYaw, float headPitch) {
    this.root().getAllParts().forEach(ModelPart::resetPose); 
    this.animateWalk(ModAnimationDefinitions.MUGA_WALKING, limbSwing, limbSwingAmount, 1f, 1f );
	this.animate(((MugaEntity)entity).idleAnimationState, ModAnimationDefinitions.MUGA_IDLE, ageInTicks, 1f); 
    this.animate(((MugaEntity)entity).attackAnimationState, ModAnimationDefinitions.MUGA_ATTACK, ageInTicks, 1f); }
