Use Poly Shape tool with Custom script

[deltamish 1]

Hey ,

I was working on a runtime simulation tool for which I wanted to use the pb_Poly shape to allow user to create meshes of any shape dynamically 

 

So decided to appent points  in pb_poly shape manually 

 

Problem is the points are not getting connected at the end. And thus no poly is drawn 

 

Could you be kind enough to let me know how to go around this 

 

thanks

At the moment the poly shape functions are not in the public API. I've exposed them for the next update (3.0.2) and will include an API Example showing how to use it.

Edit - If you're using the Asset Store version of ProBuilder this might actually work. I haven't tested it.

 

using UnityEngine;
using ProBuilder.Core;
using ProBuilder.MeshOperations;

namespace ProBuilder.Examples
{
	public class CreatePolyShape : MonoBehaviour
	{
		public float m_RadiusMin = 1.5f;
		public float m_RadiusMax = 2f;
		public float m_Height = 1f;
		public bool m_FlipNormals = false;

		pb_Object m_Mesh;

		void Start()
		{
			// Create a new GameObject
			var go = new GameObject();

			// Add a pb_Object component (ProBuilder mesh data is stored here)
			m_Mesh = go.gameObject.AddComponent<pb_Object>();

			InvokeRepeating("Rebuild", 0f, .1f);
		}

		void Rebuild()
		{
			// Create a circle of points with randomized distance from origin.
			Vector3[] points = new Vector3[32];

			for (int i = 0, c = points.Length; i < c; i++)
			{
				float angle = Mathf.Deg2Rad * ((i / (float)c) * 360f);
				points[i] = new Vector3(Mathf.Cos(angle), 0f, Mathf.Sin(angle)) * Random.Range(m_RadiusMin, m_RadiusMax);
			}

			// CreateShapeFromPolygon is an extension method that sets the pb_Object mesh data with vertices and faces
			// generated from a polygon path.
			m_Mesh.CreateShapeFromPolygon(points, m_Height, m_FlipNormals);
		}
	}
}

Hi, it works fine in 2017.3 with ProBuilder from AssetStore, thanks!

Just had to change usings.

Keep updating API please. We are looking forward to procedurally generate objects in our game.

Hey sorry for the delayed response.

Solved the issue it was just I had missed out the following lines and had to add first point again 

pb_object.ToMesh();
pb_object.Refresh();

 

Thank you so much for the circle example will use that in my project
