Question Draw Angle between 2 points in Mesh

I want to draw the Angle between point B and point C in point A. But all these points move dynamically, so they might have different values in all axis. How can I draw a mesh for this?

 

There is no point in sharing these numbers here with us.

If the points are moving constantly, then you just have to modify the mesh each frame as they move, using their current position each frame, that's all. If you can do it once, you can do it every frame (in LateUpdate)

 

There is a lot of ressources on how to create a custom mesh. Make sure to draw the triangle clockwise from view direction, or it wont show. Redraw the mesh when these values change.

 

Yeah, I know but it was so people have the same values as I do in the example, to try to achieve the mesh.

 

Code (CSharp):

1. using UnityEngine;
2.  
3. public class Connect : MonoBehaviour
4. {
5.     void Start()
6.     {
7.         Vector3[] points=new Vector3[3];
8.         points[0]=Random.insideUnitSphere*5f;
9.         for (int p=0;p<points.Length-1;p++)
10.         {
11.             points[p+1]=Random.insideUnitSphere*5f;
12.             GameObject cyl=GameObject.CreatePrimitive(PrimitiveType.Cylinder);
13.             float length=Vector3.Distance(points[p+1],points[p]);
14.             cyl.transform.localScale=new Vector3(0.1f,length/2f,0.1f);
15.             cyl.transform.position=points[p]+(points[p+1]-points[p])/2;
16.             cyl.transform.up=points[p+1]-points[p];
17.         }
18.     }
19. }

 

Line renderer version:

Code (CSharp):

1. using UnityEngine;
2.  
3. public class Connect : MonoBehaviour
4. {
5.     void Start()
6.     {
7.         LineRenderer lr=gameObject.AddComponent<LineRenderer>();
8.         lr.material = new Material(Shader.Find("Sprites/Default"));
9.         lr.material.color=Color.green;
10.         Vector3[] points=new Vector3[3];
11.         lr.positionCount=points.Length;
12.         lr.widthMultiplier=0.1f;
13.         for (int p=0;p<points.Length;p++)
14.         {
15.             points[p]=Random.insideUnitSphere*5f;
16.             lr.SetPosition(p,points[p]);
17.         }
18.     }
19. }
