Error: godot ysort not working

What's Causing This Error

The YSort node in Godot is used to change the drawing order of its children based on their Y position. When it seems not to work, the causes could be one or more of the following:

1. Layering Issue: The YSort node only affects the rendering order of its direct children. If the sprites or objects meant to be sorted are not direct children, they won't be affected.
2. Inheritance Problem: If the objects are not inheriting from Node2D (or a class that does), YSort will not work with them.
3. Incorrect Positioning: For YSort to work correctly, the nodes must have different Y positions. If they are all at the same Y position, there will be no visible sorting effect.
4. Disabled Property: The YSort's enabled property might be set to false either in the editor or via code.
5. Z-Index Interference: If the nodes have manually set z_index properties, it may interfere with the YSort functionality, as z_index has priority over YSort.
6. Scaling Issues: Nodes being scaled negatively in the Y direction could potentially cause unexpected behavior with YSort.

Solution - Here's How To Resolve It

Here are some steps to resolve issues with YSort not working:

1. Correct Parenting: Ensure that all the nodes you want to sort are direct children of the YSort node.
2. Class Check: Make sure that all child nodes are instances of Node2D or a class that inherits from it.
3. Verify Positions: Check that the children nodes have varying Y positions for the sort to take effect.
4. Enable YSort: Confirm that the YSort node is enabled; you can check and set this property both in the editor and through code (ysort_node.enabled = true).
5. Manage Z-Index: If you've set a z_index on any of the children, either remove it or ensure it’s consistent with the desired sorting.
6. Reset Scaling: If any child nodes are scaled negatively in the Y direction, try resetting the scale, as this could affect sorting.
7. Use Sorting Layers: In addition to YSort, you can also use the layer and z_as_relative properties to control draw order further.
8. Debugging: Utilize Godot's debugging tools to visualize the scene tree and ensure that nodes are nested and positioned as expected.

By systematically going through these steps, you should be able to identify and fix the issue causing YSort to not work as intended.
