Need help with Multiple Line renderers..

Hi guys, so I'm trying to create a shotgun for my game. The rays are working and enemies get damaged in radius of -3 +3, but I dont know how to create a line renderer for each "bullet".

This allows me to shoot rays:

Code (CSharp):

1. void Shoot ()
2.     {
3.         Vector3 test1 = new Vector3 (0, 0, 2);
4.         Vector3 test2 = new Vector3 (0, 0, -2);
5.         Vector3 test3 = new Vector3 (0, 0, 3);
6.         Vector3 test4 = new Vector3 (0, 0, -3);
7.         Vector3 test5 = new Vector3 (0, 0, 1);
8.  
9.  
10.         shootRay.origin = transform.position;
11.         shootRay.direction = transform.forward;
12.         shootRay2.origin = transform.position + test1;
13.         shootRay2.direction = transform.forward;
14.         shootRay3.origin = transform.position + test2;
15.         shootRay3.direction = transform.forward;
16.         shootRay4.origin = transform.position + test3;
17.         shootRay4.direction = transform.forward;
18.         shootRay5.origin = transform.position + test4;
19.         shootRay5.direction = transform.forward;
20.         shootRay6.origin = transform.position + test5;
21.         shootRay6.direction = transform.forward;
22. }

I have created few different Line Renderers in my prefabs folder and I want to use them in the array which I made:

Code (CSharp):

1. public LineRenderer[] lines;

P.S. When I put my Line Renderers to this array and start the game - they disappear for some reason...

So the question is: how do I get my line renderers to do this :

Code (CSharp):

1. Line1.enabled = true;
2. Line1.SetPosition (0, transform.position);
3. Line1.SetPosition (1, shootRay.origin + shootRay.direction * range);

 

so I'm still trying to get multiple line renderers..

I've tried creating a list of line renderers and add gameobject prefabs with line renderers in them to the list.

Code (CSharp):

1. LineRenderer line1;
2. public LineRenderer[] lines;
3.  
4. void Awake ()
5. {
6.    line1 = lines[0].gameObject.GetComponent<LineRenderer>();
7. }
8.  
9. void Shoot ()
10. {
11.     line1.enabled = true;
12.     line1.SetPosition (0, transform.position);
13.     line1.SetPosition (1, shootRay.origin + shootRay.direction * range);
14. }

Compiler doesn't give any errors, but no lines are being created.

I also tried adding my gameobjects with line renderers to my weapon as children and then calling them:

Code (CSharp):

1. line1 = GetComponentInChildren<LineRenderer>();

which works, but I can only get 1 line renderer this way..

 

Ok finally I managed to get it working....

Code (CSharp):

1.         GameObject Line1;
2.     GameObject Line2;
3.     GameObject Line3;
4.     GameObject Line4;
5.     GameObject Line5;
6.     GameObject Line6;
7.     LineRenderer line1;
8.     LineRenderer line2;
9.     LineRenderer line3;
10.     LineRenderer line4;
11.     LineRenderer line5;
12.     LineRenderer line6;
13.         Ray shootRay1;
14.     Ray shootRay2;
15.     Ray shootRay3;
16.     Ray shootRay4;
17.     Ray shootRay5;
18.     Ray shootRay6;
19.  
20. void Awake ()
21. {
22.  
23.         Line1 = GameObject.Find ("Line1");
24.         line1 = Line1.GetComponent<LineRenderer> ();
25.        
26.         Line2 = GameObject.Find ("Line2");
27.         line2 = Line2.GetComponent<LineRenderer> ();
28.  
29.         Line3 = GameObject.Find ("Line3");
30.         line3 = Line3.GetComponent<LineRenderer> ();
31.  
32.         Line4 = GameObject.Find ("Line4");
33.         line4 = Line4.GetComponent<LineRenderer> ();
34.        
35.         Line5 = GameObject.Find ("Line5");
36.         line5 = Line5.GetComponent<LineRenderer> ();
37.        
38.         Line6 = GameObject.Find ("Line6");
39.         line6 = Line6.GetComponent<LineRenderer> ();
40. }
41.  
42. void Shoot ()
43. {
44.         Vector3 test1 = new Vector3 (0, 0, 2);
45.         Vector3 test2 = new Vector3 (0, 0, -2);
46.         Vector3 test3 = new Vector3 (0, 0, 3);
47.         Vector3 test4 = new Vector3 (0, 0, -3);
48.         Vector3 test5 = new Vector3 (0, 0, 1);
49.  
50.  
51.         shootRay1.origin = transform.position;
52.         shootRay1.direction = transform.forward;
53.         shootRay2.origin = transform.position + test1;
54.         shootRay2.direction = transform.forward;
55.         shootRay3.origin = transform.position + test2;
56.         shootRay3.direction = transform.forward;
57.         shootRay4.origin = transform.position + test3;
58.         shootRay4.direction = transform.forward;
59.         shootRay5.origin = transform.position + test4;
60.         shootRay5.direction = transform.forward;
61.         shootRay6.origin = transform.position + test5;
62.         shootRay6.direction = transform.forward;
63.  
64.         timer = 0f;
65.         line1.enabled = true;
66.         line1.SetPosition (0, transform.position);
67.         line1.SetPosition (1, shootRay1.origin +              shootRay1.direction * range);
68.  
69.         line2.enabled = true;
70.         line2.SetPosition (0, transform.position);
71.         line2.SetPosition (1, shootRay2.origin + shootRay2.direction * range);
72.  
73.         line3.enabled = true;
74.         line3.SetPosition (0, transform.position);
75.         line3.SetPosition (1, shootRay3.origin + shootRay3.direction * range);
76.    
77.         line4.enabled = true;
78.         line4.SetPosition (0, transform.position);
79.         line4.SetPosition (1, shootRay4.origin + shootRay4.direction * range);
80.        
81.         line5.enabled = true;
82.         line5.SetPosition (0, transform.position);
83.         line5.SetPosition (1, shootRay5.origin + shootRay5.direction * range);
84.        
85.         line6.enabled = true;
86.         line6.SetPosition (0, transform.position);
87.         line6.SetPosition (1, shootRay6.origin + shootRay6.direction * range);
88. }
89.  

probably not the most efficient coding..

 

Use Arrays or Lists in your code, it will optimize it 10x better

 

Hey djfunkey. I've tried creating an array of line renderers like this:

Code (CSharp):

1. LineRenderer line1;
2. public LineRenderer[] lines;
3. void Awake ()
4. {
5.    line1 = lines[0].gameObject.GetComponent<LineRenderer>();
6. }
7. void Shoot ()
8. {
9.     line1.enabled = true;
10.     line1.SetPosition (0, transform.position);
11.     line1.SetPosition (1, shootRay.origin + shootRay.direction * range);
12. }

But I couldnt get any lines rendered at all. Could you help me setting it up?
