need help for loop and reset GUI

hi ...
iam trying to create something like a slideshow with GUI, OnTriggerEnter and exit but i dont get it how to loop the textures and reset the GUI to texture 1 after exit the trigger (or re enter)

any ideas?

thanks in advance =)

Code (JavaScript):

1. #pragma strict
2.  
3. private var guiShow : boolean = false;
4.  
5. var texture1 : Texture;
6. var texture2 : Texture;
7. var texture3 : Texture;
8. var texture4 : Texture;
9.  
10.  
11. function OnTriggerEnter (Col : Collider)
12. {
13.     if(Col.tag == "Player")
14.     {
15.         guiShow = true;
16.     }
17. }
18.  
19. function OnTriggerExit (Col : Collider)
20. {
21.     if(Col.tag == "Player")
22.     {
23.         guiShow = false;
24.     }
25.  
26. }
27.  
28. function OnGUI()
29. {
30.     if(guiShow == true)
31.     {
32.         GUI.DrawTexture(Rect(Screen.width / 5.5, Screen.height / 10, 1224, 818), texture1);
33.    
34.     wait();
35.                
36.     }
37.    
38. }
39.  
40. function wait()
41. {
42.     yield WaitForSeconds(1);
43.  
44.         texture1=texture2;
45.  
46.     yield WaitForSeconds(1);
47.  
48.         texture2=texture3;
49.        
50.     yield WaitForSeconds(1);
51.  
52.         texture3=texture4;
53.        
54. }
55.  

 

Use an array and a counter. OnTriggerEnter --> counter++

Use that then to loop through the textures in OnGUI

 

thanks for advice but iam still struggling with this ...
problem is, i dont know why it jumps between i = 0,1,2 and never goes up to i = 3
and the yield function will not work doesnt matter where i place it ... now its like a strobscope ^^

iam new to this so maybe theres a BIG fail in the code

thanks again!

Code (JavaScript):

1. pragma strict
2.  
3. private     var guiShow : boolean = false;
4.  
5.             var texture : Texture[];
6. private        var i : int;
7.              
8.  
9. function OnTriggerEnter (Col : Collider)
10. {
11.     if(Col.tag == "Player")
12.  
13.     {
14.         guiShow = true;
15.      
16.     }
17.     for (var i : int =0; i <= 3; i++)
18.      
19.         {
20.      
21.         }
22. }
23.  
24. function OnTriggerExit (Col : Collider)
25. {
26.     if(Col.tag == "Player")
27.     {
28.         guiShow = false;
29.  
30.     }
31.  
32. }
33.  
34. function OnGUI()
35. {
36.     if(guiShow == true)
37.     {
38.         GUI.DrawTexture(Rect(Screen.width / 5.5, Screen.height / 10, 1224, 818), texture[i++]);
39.         loop();  
40.     }
41.  
42. }
43.  
44. function loop()
45. {
46. if(i==3)
47.     {
48.     i=0;
49.     return;
50.     }
51. }

 

You are calling loop every frame. That does not work. You should not be calling such functions in OnGUI.

Also,, don't use i++ in DrawTexture. How fast do you want to loop through the textures?

 

every 2 secondes 1 texture ..

 

Then you need to make a timer in update.

 

thanks! got it ...
