Binding Error when backporting feature from 4 to 3.2

WhereAreMyPants

Hello,

I'm back-porting the gltf2 importer/exporter from Godot 4 to 3.2

I'm stuck because of this error : Error C2672 'create_method_bind': no matching overloaded function found #godot\core\class_db.h 266

if I comment the offending line that binds the 'add_surface' function, everything compiles fine.

Here is the definition of 'add_surface' in c++

I've tried the 'shot in the dark' method of bringing the class_db of 4 into 3.2 (and other than this particular error, it compiles with no changes needed) but no luck.

I'll probably put my repo up on github and give a link later today, when I'm off from work.

Right off, I'm not sure what would be causing the issue. What I might suggest is taking a look at a Godot 3.2 node that binds functions and compare how the function is being used to see if anything jumps out.

There are a number of significant changes between 4 and 3 that I would not recommend patching 4.0 core source into 3x of any flavor!

I think the best approach is to search the 3x source for how methods that take Material references are described to a bind_method call and use that coding 'phrase' instead. I think this will clear up your problem.

@TwistedTwigleg + @dotted : Thanks for the answers, I hoped someone would know exactly what to do so I could avoid diving into template definitions that bindings rely on. For now I am going to use a workaround (break the set_surface method in two). Once I have something that works I might get back and fix it.

I'll make a post when this little project has something to show Thanks Again !
