My Unity tutorial game code has only two bugs but I don't know what they mean. RRS feed

  • Question

  • Here my code:

    using System.Collections;
    using System.Collections.Generic;
    using UnityEngine;
    public class player : MonoBehaviour
    float angle = 0;
    int xSpeed = 3;
    void Start()
    void Update()
    void Moveplayer()
    Vector2 pos = transform.position;
    pos.x = Mathf.Cos(angle)*3;
    pos.y = 0;
    transform.position * pos;
    angle += Time.deltaTime * xSpeed;

    I don't even know what I'm missing, But I'm also a horrible coder. I just want mt player to move properly.

  • Can you give us any clues as to what the bugs are? Or do we have to guess?

  • That overrides the position every time.  Usually you'd want to add something to the current position.  What you have there will have the position wiggle back and forth along the X axis, since you force Y to 0.

    I suspect you really wanted:

        pos.x += Mathf.Cos(angle) * 3;
        pos.y += Mathf.Sin(angle) * 3;

    but you still have to worry about exceeding the limits of your space.

  • Hello,

     Try placing a semicolon at the end of method void update()

    or correct the scoping with proper brackets {}.  Ante is correct also.

    Hope this helps :)

  • Yes absolutely. Here you go.

    Assets\playerMovementUpdate.cs(line 18, line 5): error CS1519: Invalid token '{' in class, struct, or interface member declaration

    Error #2:

    Assets\playerMovementUpdate.cs(line 36, line 1): error CS1022: Type or namespace definition, or end-of-file expected

  • Greetings CC (I forgot the greeting last time. Sorry for my bad manners.)

    It looks like you have a couple of lines in the middle that probably would cause errors like that. Specifically you have a method called Update with no body (nothing between braces) and a superfluous definition of MovePlayer.

    And by the way, it's better to insert code via the tool on the toolbar than to show a screenshot. That way, we can easily copy and paste to make suggested improvements/corrections without having to retype anything. It's not a big deal in this case, but for long code where we need to make a lot of edits, it matters.
