Unity2D animation stops after it finished first animation

Question

void attacking()
    {
        if ((_attack.attackk || Input.GetMouseButtonDown(0)) && spr.flipX==false)
        {
            anim.Play("SlashR");

        }if((_attack.attackk || Input.GetMouseButtonDown(0)) && spr.flipX==true){
            anim.Play("SlashL");
        }

        if (health.rectTransform.sizeDelta.x <= 0)
        {
            anim.SetBool("death", true);
            isDeath = true;
        }
        else
        {
            anim.SetBool("death", false);
            isDeath = false;
        }
    }

İ'm trying to make a 2D hack&slash game,and that's why i need a combat system. So,to do this i wanted to make two animation,SlashR is for right sword and SlashL is for left sword.What i want to do is that if i press mouse button and my character is turn Right then will play SlashR anim,and vice versa. But when i press mouse button(flipX=false) SlashR animation plays only for one times.After one animation is finished,animation stops completely and vice versa. But there's weird thing as well,when i turn my character left and after that turn right,SlashR animation is playing again. Note: Loop time unchecked for SlashR and SlashL

Answer 1

Based on your State-diagram from your Animator, your SlashR and SlashL state does not go back to Idle after they are done.
This will cause the slashing-states to stay in their current state after the animation is done.

Make a state-transition from SlashR and SlashL to Idle (or whatever state you want) and it should fix the problem.

Edit

But there's weird thing as well,when i turn my character left and after that turn right,SlashR animation is playing again.

That is because in your

        if ((_attack.attackk || Input.GetMouseButtonDown(0)) && spr.flipX==false)
    {
        anim.Play("SlashR");

    }if((_attack.attackk || Input.GetMouseButtonDown(0)) && spr.flipX==true){
        anim.Play("SlashL");
    }

you do not check if the player is currently attacking first.
This results in the other animation to immediately start playing when the player moves left-right while it is attacking.

The solution is to properly make use of your animators as so:

And your new code should be:

if ((_attack.attackk || Input.GetMouseButtonDown(0)) && spr.flipX==false) {
     anim.SetTrigger("SlashR");
} else if((_attack.attackk || Input.GetMouseButtonDown(0)) && spr.flipX==true){
    anim.SetTrigger("SlashL");
}
