Code error with character controller

Unity Blockchain Game Development 101
#1

I’ve entered the same code as Ivan in the video but I’m getting an error from unity.

assets/scritps/playercontroller.cs(15,43): error cs1525: Invalid expression term ‘)’

Here’s the code I wrote and that was in the video.

rb = GetComponent<RigidBody 2D>(); (FYI, RigidBody2D as written in the video gave me an error because unity places a space between RigidBody and 2D in the “get component” section.

It’s giving an error for the close parenthesis. Any ideas what needs to be fixed?

#2

I think I figured this out but now I’m having another error. Basically the PlayerController isn’t showing up in the add component section when I search for it. So I can’t control my jelly at all. The error I’m getting is playercontroller.update() must declare a body because it is not marked abstract, extern or partial. I’ve watched over the videos a few times and I believe the code is correct but Unity is not allowing me to add the player controller component. Thanks for any help

Could you please share your code in the following way? It will be easier for us to understand the issue and help you solve it :nerd_face:

       MoveInput = Input.GetAxis("horizontal");
       rb.velocity = new vector2(moveinput*speed, rb.velocity.y);
       JumpInput = Input.GetAxis("vertical");
       if(JumpInput > 0 && timesJumped < jumpsAllowed && previousJumpInput == 0);
    { 
       rb.velocity = new vector2(rb.velocity.x, jumpforce); 
       timesJumped++; 
    }

    previousJumpInput = jumpInput;
}    
 
    void OnCollisionEnter2D(Collision2D other)
    {
        if(other.gameObject.CompareTag("Ground"))
        {
            timesJumped = 0;
        } 
    }
    // Update is called once per frame
    void Update();

}

In your PlayerController the update function should contain at least the body brackets {}
