Car text trigger

Hello all,

I'm making an horror game.

I'd like an script on a car that if you press "E" an text appear.

And after press "E "again the text dissapears..

Some1 can help me?

Regards,

Melchet

 

Maybe try a script with something like this:

Code (CSharp):

1.         bool textShowing = false;
2.  
3.         void Update ()
4.         {
5.                 if (Input.GetKeyDown (KeyCode.E))
6.                         textShowing = !textShowing;
7.         }
8.  
9.         void OnGUI ()
10.         {
11.                 if (!textShowing)
12.                         return;
13.  
14.                 GUIStyle style = new GUIStyle ();
15.                 style.fontSize = 130;
16.                 style.normal.textColor = Color.white;
17.                 GUI.Label (new Rect (10, 10, 100, 20), "Hello World!", style);
18.         }

 

I get 4 errors:

Error line 14 and 17

 

What do the errors say?

 

Here I taken an screenshot from it

 

I want put the script on this car

 

the errors

 

I think there are two issues.

One issue is that I think it is a problem to put a space in the name of a Unity script. So, you should change “car text” to “cartext” or something without a space.

Also, here is some code that assumes you have named your script “cartext”:

Code (CSharp):

1. using UnityEngine;
2. using System.Collections;
3.  
4. public class cartext : MonoBehaviour
5. {
6.         bool textShowing = false;
7.  
8.         void Update ()
9.         {
10.                 if (Input.GetKeyDown (KeyCode.E))
11.                         textShowing = !textShowing;
12.         }
13.    
14.         void OnGUI ()
15.         {
16.                 if (!textShowing)
17.                         return;
18.        
19.                 GUIStyle style = new GUIStyle ();
20.                 style.fontSize = 130;
21.                 style.normal.textColor = Color.white;
22.                 GUI.Label (new Rect (10, 10, 100, 20), "Hello World!", style);
23.         }
24. }

The code I gave you before was a snippet and wasn’t intended to occupy the whole file.

 

Hello boolfone,

the script worked.

But now I got the problem if I press the 'E ' key the text shows anywhere..

I have putted the script on the car itself

 

You can move the text by setting the first two parameters to the Rect constructor in this line:

GUI.Label (new Rect (10, 10, 100, 20), "Hello World!", style);

Also, if you want, you can use this script:

Code (CSharp):

1. using UnityEngine;
2. using System.Collections;
3.  
4. public class cartext : MonoBehaviour
5. {
6.         bool textShowing = false;
7.         public float x;
8.         public float y;
9.  
10.         void Update ()
11.         {
12.                 if (Input.GetKeyDown (KeyCode.E))
13.                         textShowing = !textShowing;
14.         }
15.  
16.         void OnGUI ()
17.         {
18.                 if (!textShowing)
19.                         return;
20.      
21.                 GUIStyle style = new GUIStyle ();
22.                 style.fontSize = 130;
23.                 style.normal.textColor = Color.white;
24.                 GUI.Label (new Rect (x, y, 100, 20), "Hello World!", style);
25.         }
26. }

Then you can adjust the x and y position for the text like so:

 

Thx for the video.

but that isn't actualy the answer on my question.

the problem is the text what belong with the car gonna show up everywhere when I press the 'E"button.

It only needs to be showing at the car.

 

You can decrease the font size by modifying this line:

Code (CSharp):

1. style.fontSize=130;

 

Let me explain better,

This picture is the good position when I pressing 'E'.

Now the girl stances to the car

This picture is the bad one, here I press 'E' too but without the car. I need the text only shown up at the car as the picture above.

 

How do I make that possible?
