convert js to C#

Hey guys,

I'm not any good with C# but I'm learning...
could you help me fix up this code? I tried to convert it to C# but I get errors about the lines I marked with ">>>"
The error is: "Expression denotes a 'type', where a 'variable', 'value' or 'method group' was expected

Code (csharp):

1.  
2. using UnityEngine;
3. using System.Collections;
4.  
5. public class spheremovec : MonoBehaviour {
6. bool  grounded = true;
7. float jumpnum = 10;
8. float Rollspeed = 4;
9. public float panning;
10. void  Update (){
11.  
12. panning = Input.GetAxis("Pan");
13.  
14.  
15.  
16.        float horiz = Input.GetAxis("Horizontal");
17.         float vert = Input.GetAxis("Vertical");
18.         >>>rigidbody.AddForce(Vector3(horiz/Time.deltaTime/Rollspeed,0,vert/Time.deltaTime/Rollspeed));
19.     if(grounded){
20.    
21.                 if (Input.GetButtonDown ("Jump")) {
22.                     float jump = 5/Time.deltaTime;
23.                     grounded = false;
24.                     float jumpup = jumpnum*jump;
25.                
26.                     >>>rigidbody.AddForce(Vector3(0,jumpup,0));
27.                 }
28.  
29. }
30. }
31.  
32. void  OnCollisionEnter ( Collision theCollision  ){
33.  
34. grounded = true;
35.  
36. }
37.  
38.  
39. }

thank you very much!

shouldn't there be
new Vector3(...)
?

 

where?

 

...
>>>rigidbody.AddForce(new Vector3(horiz/Time.deltaTime/Rollspeed,0,vert/Time.deltaTime/Rollspeed));
...
>>>rigidbody.AddForce(new Vector3(0,jumpup,0));
...

 

oh, ok. that worked. Can you explain why?

 

C# syntax, variables need to be allocated
you should maybe check JS <-> C# differences

 

Found here. It doesn't say anything, however, about having to use "new" to do allocation (you have to do allocation with JS, it's just obscured by the syntax and lets you delay specifying a type). In short, it's just the way things are done. The Javascript-flavored Unity scripting syntax tries to mimic Javascript syntax where everything is handled as though it's a function where C# hews closer to, well, C# and other statically-typed languages.

If you read the "Writing scripts in C#" page and it's unclear that you need to use "new" to allocate objects in C#, consider filing a bug (using the in-Editor bug reporter) and mark the "Type of Problem" field as "Documentation." Give them the page URL and explain what's missing. That way, you'll help others avoid the same problem in the future. I've filed a few documentation bugs myself, and have found that UT is very receptive to suggestions on how to make the documentation better.

 

thank you!

looks like everyone is recommending C# over Unityscript. I'll start doing my best two learn it
