Line Renderer - Getting parameters by scripting?

Hi All,

I'm having a problem getting the parameters of a Line Renderer component - if I say, want to double the width of a lineRenderer, but I don't know the starting widths, there is no startWidth, or endWidth variables like there are for a trailRenderer. Is there something missing from the documentation, or does this feature not exist?

Thanks for your help!

 

Just wanted to bump this - I've got a work around, but it's pretty ugly.

Is the inability to get Line Renderer parameters a gap in Unity's documentation, or a limitation of the feature itself?

 

Maybe hidden lil bit, but they exist.
http://docs.unity3d.com/Manual/class-LineRenderer.html

 

But those aren't accessible from a script: "this.lineRenderer.StartWidth" and "this.lineRenderer.startWidth" both give compile errors. (LineRenderer does not contain definition for "startWidth"...)

The scripting reference page says "useWorldSpace" is the only accessible variable and the others are set by SetColors(), SetPositions() etc. But there are no GetPositions(), GetWidths() etc methods.

If it is possible, what is the correct syntax to get the startWidth?

 

Hmm right... seems to be write only.
Pathetic behavior... maybe should make a bug report about this.

 

http://docs.unity3d.com/ScriptReference/LineRenderer.SetWidth.html

Theres no obvious GET for the properties, only to set.

Can;t really think of a need for specifically getting, just keep a float varialbe in your script

 

Damn, how irritating. I'll file a bug report - it's possible to get them for trail renderers so it should be possible for line renderers too. Of course it is possible to cache the variable, but if you have multiple scripts acting on it, then you have to start passing that float between scripts, which is frankly, really ugly.

Thanks for your help.

 

You can get line renderer settings using the bounds property. Maybe something like this might help with what you were trying to do. The following code will return the renderer line width.

Code (CSharp):

1. LineRenderer line = getComponent<LineRenderer>();
2. float width = line.bounds.size.x;

 

Damn, now you can't get either. What do I do?

 

Now, you use .widthCurve (which is much more versatile, but does require that you know how to use AnimationCurves) and/or .widthMultiplier.

 

don't mind my last post. intellisense wasn't working making me think it didn't exist anymore
