Hi There,

I cant seem to figure out how to do this, I want to be able to set the graph below from the code during runtime. I found Unity - Scripting API: LineRenderer.SetWidth which is obsolete, and it told me to go to Unity - Scripting API: LineRenderer.widthCurve or widthStart or widthEnd. I cant seem to understand what the documentation is saying widthCurve does (Set the curve describing the width of the line at various points along its length), so I cant tell if it is what I am suppose to use for this. Could someone help explain to me what it does or if there is a different thing I should use?

It’s an animation curve just like that red line in the screenshot. For example if you wanted the width at position 0.0 to be 1.0f.

var curve = new AnimationCurve();
curve.AddKey(0.0f, 1.0f);
line.widthCurve = curve;

Thank you so much for your response, this will work perfectly :slight_smile: It definitely makes sense now, I think I just looked at it too long last week and my brain broke :slight_smile:
