Hi guys,

I have a little problem with my CSharp Code in Unity

I have 2 variables, and this two variables controls some numbers in terms of the rigidbody rotation. Now I want to change them, if I press a certain button. But Unity saiys:

Assets/Scripts/Sphere.cs(38,41): error CS1023: An embedded statement may not be a declaration or labeled statement.

The second question I have is (when this problem is fixed], how can I say Unity with the help of CSharp that this key has already been pressed and it is no more allowed to use this key again. Because this is a one time ultimate skill.

 

You've already declared hallo. On line 38, you can simply put "hallo = 300;", as the program is already aware it's an int due to line 11.

 

Thank you worked for me. Could you please answer my second question and how I can connect that with a delay, more or less that the normal speed comes back after 3 seconds, that would be very helpful

 

http://docs.unity3d.com/Manual/Coroutines.html Use a coroutine and a use a bool.

 

You were declaring the hallo variable twice, I've fixed that in the following code and added a flag to the N key input so it can only be pressed once. Hope this helps.

Code (csharp):

1. using UnityEngine;
2. using System.Collections;
3.  
4. public class Sphere : MonoBehaviour {
5.     public Vector3 startposition;
6.     public GameObject Patikelsystem;
7.     public GameObject Spring;
8.    
9.     int hallo = 30;
10.     int hallo1 = 70;
11.  
12.     bool halloToggled;  // Prevents the hallo button toggle being pressed twice.
13.  
14.     // Use this for initialization
15.     void Start () {
16.         startposition = transform.position ;
17.     }
18.  
19.     // Update is called once per frame
20.     void Update () {
21.  
22.         if(Input.GetKey(KeyCode.N)  halloToggled = false) {
23.             halloToggled = true;
24.             hallo = 300;
25.         }
26.  
27.         Spring.transform.position = new Vector3 ( transform.position.x, transform.position.y, transform.position.z) ;
28.  
29.         Patikelsystem.transform.position = new Vector3 ( transform.position.x, transform.position.y, transform.position.z) ;
30.  
31.         if(transform.position.y <= 2)
32.         {
33.             if(Input.GetKeyDown(KeyCode.L)) {
34.                 rigidbody.AddForce (0,300,0);
35.             }
36.         }
37.  
38.         if(transform.position.y <= -10 )
39.         {
40.             transform.position = startposition;
41.             rigidbody.angularVelocity = Vector3.zero;
42.             rigidbody.velocity = Vector3.zero;
43.  
44.             return;
45.         }
46.  
47.         if(Input.GetKey(KeyCode.UpArrow ) ) {
48.             rigidbody.AddTorque(hallo1*Time.deltaTime,0,0);
49.         }
50.  
51.         if(Input.GetKey(KeyCode.DownArrow)) {
52.             rigidbody.AddTorque(-hallo*Time.deltaTime,0,0);
53.         }
54.  
55.         if(Input.GetKey(KeyCode.LeftArrow)) {
56.             rigidbody.AddTorque(0,0,hallo*Time.deltaTime);
57.         }
58.  
59.         if(Input.GetKey(KeyCode.RightArrow)) {
60.             rigidbody.AddTorque(0,0,-hallo*Time.deltaTime);
61.         }
62.     }
63. }

 

Thank you, is it possible that you can add to that script a delay, because I have no clue how i shall do this with a coroutine. ( after 4 seconds should hallo = 30 and hallo1 = 70 again. Could you show me how I can make that.

If I use you script, Unity says:



Assets/Scripts/Sphere.cs(67,52): error CS1519: Unexpected symbol `(' in class, struct, or interface member declaration

Assets/Scripts/Sphere.cs(65,54): error CS1519: Unexpected symbol `)' in class, struct, or interface member declaration

If I use the old script everthing is fine

18.    
19.     int hallo1 = 70;
20.    
21.    
22.    
23.     bool halloToggled;  // Prevents the hallo button toggle being pressed twice.

27.     // Use this for initialization
28.

47.             hallo = 300;

62.

65.             if(Input.GetKeyDown(KeyCode.L)) {
66.                
67.                 rigidbody.AddForce (0,300,0);
68.

76.            
77.         {
78.            
79.             transform.position = startposition;
80.

94.            
95.             rigidbody.AddTorque(hallo1*Time.deltaTime,0,0);
96.            
97.         }
98.        
99.        
100.        
101.         if(Input.GetKey(KeyCode.DownArrow)) {
102.            
103.             rigidbody.AddTorque(-hallo*Time.deltaTime,0,0);
104.            
105.         }
106.        
107.        
108.        
109.         if(Input.GetKey(KeyCode.LeftArrow)) {
110.            
111.             rigidbody.AddTorque(0,0,hallo*Time.deltaTime);
112.

120.            
121.         }
122.        
123.     }
124.    
125. }

 

Woops I forgot to add an extra = in the If, and I've added a coroutine that delays input 4 seconds after you press the N key, if you want it for any of the other keys simply put the halloToggled flag in their if statements and call InputDelay.

Code (csharp):

1. using UnityEngine;
2. using System.Collections;
3.  
4. public class Sphere : MonoBehaviour {
5.  
6.     public Vector3 startposition;
7.     public GameObject Patikelsystem;
8.     public GameObject Spring;
9.  
10.     int hallo = 30;
11.     int hallo1 = 70;
12.     bool halloToggled;  // Prevents the hallo button toggle being pressed twice.
13.  
14.     // Use this for initialization
15.     void Start () {
16.         startposition = transform.position ;
17.     }
18.  
19.     // Update is called once per frame
20.     void Update () {
21.  
22.         if(Input.GetKey(KeyCode.N)  halloToggled == false) {
23.             halloToggled = true;
24.             hallo = 300;
25.             StartCoroutine("InputDelay");
26.         }
27.  
28.         Spring.transform.position = new Vector3 ( transform.position.x, transform.position.y, transform.position.z) ;
29.         Patikelsystem.transform.position = new Vector3 ( transform.position.x, transform.position.y, transform.position.z) ;
30.  
31.         if(transform.position.y <= 2)
32.         {
33.             if(Input.GetKeyDown(KeyCode.L)) {
34.                 rigidbody.AddForce (0,300,0);
35.             }
36.         }
37.  
38.         if(transform.position.y <= -10 )
39.         {
40.             transform.position = startposition;
41.             rigidbody.angularVelocity = Vector3.zero;
42.             rigidbody.velocity = Vector3.zero;
43.             return;
44.         }
45.  
46.         if(Input.GetKey(KeyCode.UpArrow ) ) {
47.             rigidbody.AddTorque(hallo1*Time.deltaTime,0,0);
48.         }
49.  
50.         if(Input.GetKey(KeyCode.DownArrow)) {
51.             rigidbody.AddTorque(-hallo*Time.deltaTime,0,0);
52.         }
53.  
54.         if(Input.GetKey(KeyCode.LeftArrow)) {
55.             rigidbody.AddTorque(0,0,hallo*Time.deltaTime);
56.         }
57.  
58.         if(Input.GetKey(KeyCode.RightArrow)) {
59.             rigidbody.AddTorque(0,0,-hallo*Time.deltaTime);
60.         }
61.     }
62.  
63.     float delay = 4.00f;
64.     IEnumerator InputDelay() {
65.         yield return new WaitForSeconds(delay);
66.         halloToggled = false;
67.         hallo = 30;
68.     }
69. }

 

Thnak you it worked without problems. Could i ask you another question.

I implemented a GUI text Gameobject. But I don´t know how I can address it. I want the GUIShow to count +1 if the Sphere is under .y -10 (that is the part I already scripted.). But i don´t know how to combine.

 

If you define GUIShow as a GUIText object you can directly access it's text. Best way would be to have a variable that stores what you want to print out in GUIShow for example:

Code (csharp):

1.  
2. var guiCount: int = 0;
3. GUIShow.text = guiCount++;
4.  

You'll want to put the second line in the if statement that determines if the y is below -10.

following problems occured:

Assets/Scripts/Kegel.cs(55,29): error CS1525: Unexpected symbol `:', expecting `)', `,', `;', `[', or `='

Do you know how to fix this ?

PS: I wrote public Gameobject Guishow not public Gameobject GUIShow maybe you have overlooked that.

 

You'll want to move the declaration of guiCount out of Update, and it will need to be in C# syntax.

Code (csharp):

1. int guiCount = 0;

Also you'll need to change GUIShow.text to Guishow.text, and update the type of it to GUIText.
