LineRenderer.widthMultiplier

설명

Set an overall multiplier that is applied to the LineRenderer.widthCurve to get the final width of the line.

using UnityEngine;
using System.Collections;

public class ExampleClass : MonoBehaviour
{
    public float width = 1.0f;
    public bool useCurve = true;
    private LineRenderer lr;

        // Set some positions
        Vector3[] positions = new Vector3[3];
        positions[0] = new Vector3(-2.0f, -2.0f, 0.0f);
        positions[1] = new Vector3(0.0f, 2.0f, 0.0f);
        positions[2] = new Vector3(2.0f, -2.0f, 0.0f);
        lr.positionCount = positions.Length;
        lr.SetPositions(positions);
    }
