Get the height of collision shape for c# (not gdscript)

GDScript:

$CollisionShape

Is equivalent to

get_node("CollisionShape")

Which translates to C# as:

GetNode("CollisionShape")

However, C# cares for types, so do this:

GetNode<CollisionShape>("CollisionShape")

Now it should show you the Shape property:

GetNode<CollisionShape>("CollisionShape").Shape

Ern... Not all Shape have "height". C# won't let you use it, until it knows it is a type that has it. I'll assume it is a capsule shape, so do this:

var shape = (CapsuleShape)GetNode<CollisionShape>("CollisionShape").Shape;

If you are not sure it is a CapsuleShape, you can do something like this:

if (GetNode<CollisionShape>("CollisionShape").Shape is CapsuleShape shape)
{
    // ...
}

Or like this (which could give you null, if it isn't):

Shape? shape = GetNode<CollisionShape>("CollisionShape").Shape as CapsuleShape;

Now you should be able to get Height:

var height = shape.Height;

No, the extra variables not always necessary.

If you don't want to use types, you have an alternative -less safe, less performant- way of doing things:

var height = (float)GetNode("CollisionShape").Get("Shape").Get("Height");

Sometimes it is convenient to write things like this to begin with, and convert to the other way as necessary. In particular while translating code from GDScript to C#.

It is also possible to do a mix of the two approaches:

var height = (float)GetNode<CollisionShape>("CollisionShape").Shape.Get("Height");

I believe this can also be done in C# using dynamic, here:

var height = ((dynamic)GetNode("CollisionShape").Shape).Height;

Or here:

var height = ((dynamic)GetNode("CollisionShape")).Shape.Height;

However, you are not going to get IntelliSense.
