I don't know why I get this error

Error CS1022: Type or namespace definition, or end-of-file expected

My code:

public class weaponcontroller : MonoBehaviour
{
    public gameobject sword1;
    public bool canAttack = true;
    public float attackcooldown = 1.0f;
    
    public void update();
    {
        if (input.getmousebuttondown(0))
        {
            if (canAttack)
            {
                swordAttack();
            } 
        }
    }

    public void swordAttack();
    {
        canAttack = false;
        animator anim = sword1.getcomponent<animator>();
        anim.settrigger("attack");
    }

    IEnumerator resetattackcooldown()
    {
        yield return new waitforseconds(attackcooldown);
        canAttack = true;
    }
}

Do not put a semicolon after the closing parenthesis of a method argument block

CodePudding user response：

In c# we use the semi colon to close our statements. A method is a statement that contains other statements!

public void update(); "<-- Tells the code to run \"public void update\". But it can't access the contents because the method hasn't been fully declared."
