Help with Sanity Script(Again)

Like I said I last thread I posted, I'm sort of newb with javascript. Anyway, What I want my script to do is to take 20 away from my Sanity variable everytime I enter a trigger, and then have it take away the current hud, and put up the next, and it works for the first trigger I enter, but not the second.
Here's the script...

Code (JavaScript):

1.  
2. var hud: GameObject;
3. var hud2 : GameObject;
4. var hud3 : GameObject;
5. var hud4 : GameObject;
6. var hud5 : GameObject;
7. var hud6 : GameObject;
8.  
9. var hasplayed = false;
10. var entertrigger = false;
11. var entertrigger1 = false;
12. var entertrigger2 = false;
13. var entertrigger3 = false;
14. var entertrigger4 = false;
15.  
16. var Sanity = 100;
17.  
18.  
19.  
20. function Start () {
21.  
22. entertrigger = false;
23. hasplayed = false;
24. hud.renderer.enabled = true;
25. hud2.renderer.enabled = false;
26. hud3.renderer.enabled = false;
27. hud4.renderer.enabled = false;
28. hud5.renderer.enabled = false;
29. hud6.renderer.enabled = false;
30.  
31. }
32.  
33. function OnTriggerEnter (other : Collider) {
34. entertrigger = true;
35.  
36. }
37.  
38.  
39.  
40. function Update () {
41.  
42. if (entertrigger == true) {
43. Sanity = Sanity - 20;
44. hud.renderer.enabled = false;
45. hud2.renderer.enabled = true;
46. entertrigger = false;
47. }
48. if (Sanity == 80) {
49. if (entertrigger == true) {
50. Sanity = Sanity - 20;
51. hud2.renderer.enabled = false;
52. hud3.renderer.enabled = true;
53. entertrigger1 = false;
54. }
55. }
56. if (Sanity == 60) {
57. if (entertrigger == true) {
58. Sanity = Sanity - 20;
59. hud3.renderer.enabled = false;
60. hud4.renderer.enabled = true;
61. entertrigger2 = false;
62. }
63. }
64. if (Sanity == 40) {
65. if (entertrigger == true) {
66. Sanity = Sanity - 20;
67. hud4.renderer.enabled = false;
68. hud5.renderer.enabled = true;
69. entertrigger3 = false;
70. }
71. }
72. if (Sanity == 20) {
73. if (entertrigger == true) {
74. Sanity = Sanity - 20;
75. hud.renderer.enabled = false;
76. hud2.renderer.enabled = false;
77. hud3.renderer.enabled = false;
78. hud4.renderer.enabled = false;
79. hud5.renderer.enabled = false;
80. hud6.renderer.enabled = false;
81. entertrigger = false;
82. removeovertime ();
83. entertrigger = false;
84. }
85. }
86. }
87.  
88. function removeovertime (){
89. yield WaitForSeconds (2);
90. Application.LoadLevel(0);
91. }
92.  
93.  

 

Use arrays or lists for all your huds. For this you should only need 1 trigger object, and just copy it around your scene. then each time a player enters this trigger reduce the sanity by 20%. then I would use a switch statement for each sanity level.

 

So I know how to make an array, but how do I remove or add objects in the array from the game

 

A list might be more useful since it has a Add and Remove function but it works about the same as an array in practice.

List<GameObject> hudList = new List<GameObject>(); //declaration

hudList.Add(targetObject); //adds an item
hudList.Remove(targetObject); //remove target
hudList.RemoveAt(index); //remove target
