What is the correct method to scale a shape?

[DennisSmolek]

I am working on resizing bodies/shapes.
I know shapes can't change their size dynamically but need to be recreated.

In examples I saw scaled shapes were wrapped in decorator shapes: ScaledShape

However, I see the core Jolt.Shape also has a .ScaleShape() method. (here)

I do see the disclaimer on the instance method that not all shapes can be scaled, so I'm wondering if that makes the ScaledShape decorator the more stable method.

My current setup saves the ShapeSettings and when called generates a new Shape AND ScaledShape

The method pattern isn't really simpler code wise but is a different pattern.

Is there any benefit one way or the other?

I have created some documentation and a demo here: https://jrouwe.github.io/JoltPhysics/#scaling-shapes (note in C++, concepts should work in JS too)

Ah gotcha, so it's the other way around.

With the SetScale method being safer, what is the usecase for the ScaledShape decorator?

ScaleShape() uses ScaledShape internally
