I'm getting warning on LineRenderer SetWidth that it's obsolete how should i fix it?

问题

lineRenderer.SetWidth(startWidth, endWidth);
lineRenderer.SetVertexCount(linePoints.Count);

On both lines same warning:

'LineRenderer.SetVertexCount(int)' is obsolete: 'SetVertexCount has been deprecated. Please use the numPositions property instead.'

And

'LineRenderer.SetWidth(float, float)' is obsolete: 'SetWidth has been deprecated. Please use the startWidth, endWidth, or widthCurve properties instead.'

I tried this then:

lineRenderer.startWidth(startWidth, endWidth);

But then getting error on startWidth property:

'LineRenderer.startWidth' cannot be used like a method.

回答1:

Some of the LineRenderer functions has been changed to properties and also renamed to avoid confusion. You set properties not call it as a function. For lineRenderer.SetVertexCount, you use lineRenderer.positionCount to set that.

lineRenderer.startWidth = startWidth;
lineRenderer.endWidth = endWidth;
lineRenderer.positionCount = linePoints.Count;

回答2:

Just do what the compiler is suggesting.

I.E.:

lineRenderer.startWidth = startWidth;
lineRenderer.endWidth = endWidth;
lineRenderer.positionCount = linePoints.Count;
