These are the changes:
dub.jsonnow says to includeraylib, as Raylib-D isn't usable without it.Rectangle, includingtop,bottom,left, andright.@safe.Camera2D.zoomset to1.0fby default. This would make it easy to figure-out how to use.I think it makes sense for
Camera2D.zoomto be set to1.0fby default, because that is what it is usually set to straight away. The documentation for Raylib even says that it should be set to1.0fby default, which a new D programmer not experienced in C may interpret this to mean that it is set to1.0fby default.Let's just hope that there aren't any projects out there that use the value of
Camera2D.zoomto detect whether a camera has been initialized, as that would result in a breaking change here. However, I think it's unlikely that there are any programs that do that. I considered having an "enhancedD" configuration that would set things to be more D-like while keeping the default configuration to be in-line with Raylib. However, I decided to drop this idea as a new user of Raylib-D probably wouldn't think to set this configuration when starting a new project.
