Development Notes

• Developed and tested with Godot v4.2.1
• Use autoload to pre-load singletons. Try not to use singletons if possible.
• Use the debugger and the misc tab to debug mouse click events. This can show where in the node hierarchy it's getting stuck.
• If something isn't clickable, traverse up the node tree and set the Mouse -> Filter property to Ignore.
• Target screen resolution 1920x1080
• Orphaned/stray nodes are nodes that have exited the scene tree but still exist in memory resulting in a memory leak. You can use get_tree().get_root().print_stray_nodes() to debug and find them. If the code ever calls instance() but then discarding it without add_child() or if the code is using remove_child() without queue_free() these are cases that would create stray nodes.
• The .ogg sound files needed to be re-imported with loop turned off to prevent them from continuously playing and looping.
• Containers handle the rotation and other properties of the children. Therefore, I needed to parent the clickable TextureButtons to a Control node to prevent them from being reset. I used min size on the parent Control to ensure appropriate sizing and automatic layout occured otherwise everything was jammed together.
• assert() calls aren't included as part of release builds so don't use them to check for and run change_scene.
• Use OS.is_debug_build() to check for if we're running in debug or release mode.
