IndexOutOfRangeException

[nostel]

Hi, I often get this bug after running game in about 2-5 mins.

The DotTween setting is set to Default.

I use Tweener.Kill() a lot. If I don't use Tweener.Kill() I don't see this bug happen.

Error Log: This error always appear 1st IndexOutOfRangeException: Array index is out of range.

Hi, I've just found the way to replicate it. Please add this script into an empty object and run Test function.

using UnityEngine;
using System.Collections;
using DG.Tweening;

public class Test : MonoBehaviour {
	
	[ContextMenu ("Test")]
	public void TestDotTween ()
	{
		Vector3[] wps = new Vector3[1];
		Vector3 wp0 = transform.localPosition;
		wps [0] = wp0;

		Tweener tween = transform.DOLocalPath (wps, 10, PathType.CatmullRom);
	}

}

Seems like it's the case with how PathType.CatmullRom interpolates: it was either not meant for straight lines with 1 waypoint only, or the author missed this case. What worked for me was choosing PathType.Linear wherever I had only one waypoint and PathType.CatmullRom otherwise.

[Demigiant]

Ah, Catmul-Rom is definitely not meant for one-point paths :P But I'll mark in my TODO to capture the error and throw a warning instead of an error.

[unitymatrix]

still exist for this bug

[JackWong0805]

I just encounter this bug too. And have some better resolutions? Or, just some other methods to replace kill?

[JackWong0805]

emm, I just set the Capacity by mannual, and now I never encounter this bug.
