cs errors

Hey guys I'm getting the following errors - cs0201nly assignment, call, increment, decrement, and new object expressions can be used as a statement.
and cs1023:an embedded statement may not be a declaration or a labelled statement.
Here's my code -

Code (CSharp):

1. using UnityEngine;
2. using System.Collections;
3.  
4. public class elephantMove : MonoBehaviour {
5.  
6.     public playerMove playerRight; // connects to the playerMove script, type playerRight to acess the script.
7.    
8.     Vector2 offset;
9.     Vector2 elepos;
10.  
11.     Animator anim; //animator feature is now called anim
12.    
13.     // Use this for initialization
14.     void Start () {
15.         anim= GetComponent<Animator>(); //anim is linked to animator
16.     }
17.    
18.     // Update is called once per frame
19.     void Update () {
20.    
21.         offset = new Vector2(1, 0);
22.         elepos = new Vector2(transform.position.x, transform.position.y);
23.  
24.         if(GetComponent<HingeJoint2D>().enabled == true){ // is the elephant connected to the player?
25.  
26.                 if(playerRight.facingRight == false)
27.                  elepos ++ offset;
28.                 transform.position = new Vector2(elepos.x,elepos.y);
29.                
30.                
31.             if(playerRight.move < -0.3f && playerRight.facingRight == false) // if move is more than 0 and the player is NOT facing right
32.                 anim.SetBool ("eleFlipped", true);
33.                
34.             else if(playerRight.move > 0.3f && playerRight.facingRight == true) //if move is less than 0 and facing right
35.                 anim.SetBool ("eleFlipped", false);
36.  
37.             if (playerRight.playerMovingBool == true) // the player is moving
38.                 anim.SetBool ("eleSpeed", true); //set the eleSpeed bool in the animator to true, this will call the walk animation
39.  
40.             if (playerRight.playerMovingBool == false) //the player is no longer moving
41.                 anim.SetBool ("eleSpeed", false); //set the eleSpeed bool in the animator to false, this will call the idle animation
42.         }
43.  
44.     }  
45. }
46.  

 

Replace: elepos ++ offset;
It should probably be elepos += offset;

 

Sorry, I didn't explain my problem. I want it to increment by the value of offset only once. += keeps on incrementing over and over.

 

Once per....? Once per second? Only once, period? Once each time some condition is met?

 

So? You're initializing elepos on line 22. Then on line 27 you may add offset to it (just once). Then, the next time Update is called, you initialize it again.

So elepos will always be either transform.position, or one unit to the right, unless you have some other code that's changing it elsewhere.

 

Just once. so the position of the sprite offsets when the if statement becomes true.

 

So you need a boolean flag. Declare it outside the function, so that it is persistent. Check whether that is true in the if statement; inside the if statement, set it to false.

 

Ah okay. i'll give that a go the problem does seem to be due to the fact that the elepos++offset is inside that if statement, so hopefully it'll work.
Cheers
