godot-rust/gdnative (original) (raw)

The dodge_the_creeps example in godot-rust, which uses Input::is_action_pressed(), no longer compiles with Godot 3.4.

Reason is an API change in GDNative:

• Class Input for Godot 3.3:
  
• Class Input for Godot 3.4:
  

The extra parameter exact is optional, which is a non-breaking change in GDScript and C++, but a breaking one in Rust, since the language does not support default parameters.

There are likely more places in the GDNative API with such changes. At the moment, they make it impossible for godot-rust to support multiple Godot minor versions simultaneously. Either we find a way to support such APIs in Rust, or we can only support the latest minor version.
