Out of bounds get index '1' error

[ghost]

Hi, I think it is a good plugin that allows you to create ramps and stairs quite easily. At the moment the collisions are not being created so I can't use them entirely.

The error that I get in any ProtoRamp node that I add is this:
res://addons/proto_shape/proto_gizmo.gd:69 - Out of bounds get index '1' (on base: 'Array')

This is the code part:

# Add collision triangles by generating TriangleMesh from node mesh
gizmo.add_collision_triangles(node.get_meshes()[1].generate_triangle_mesh())

I could replicate the problem, but I don't think it is relatable to physics collisions. This kind of collision makes the ProtoRamp selectable with a mouse by giving the editor some shapes to guess what to select when clicking. I did not test it enough, but there is an option on CSGShape3D node to enable collisions, that might help with physics collisions.

For the time being, I am fixing the issue with line 69 (nice). I could replicate it by reparenting a ProtoRamp to another ProtoRamp.

Indeed, confirmed, that CSGShape3D collisions are great for basic physics collisions, but I intend to expand upon that features (more variety of collision types). As I am handling child nodes loosely, I tend to delete all children on property change. I will change this, so that other children won't be affected.

Decided to make the children problem another issue at #2.
