System information

Godot v4.3.stable.mono unknown - Garuda Linux #1 SMP PREEMPT_DYNAMIC Fri, 20 Sep 2024 09:23:13 +0000 - Wayland - Vulkan (Forward+) - dedicated AMD Radeon RX 6950 XT (RADV NAVI21) - AMD Ryzen 7 3800X 8-Core Processor (16 Threads)

Issue description

Export property in C# Resource class with hintString = "0.0001,1,or_greater" and PropertyHint.Range, when setup to the minimum allowed value (0.0001), displayed in Editor as 0, while still displaying correct value when hovering on the field.

When the minimum value in hintString is set to 0.001 - now it displayed correctly in the Editor.

Steps to reproduce

1. Create a custom Resource class in C#.
2. Add code [Export(PropertyHint.Range, "0.0001,1,or_greater")] public float MyValue { get; private set; }.
3. Compile code.
4. Create a new Resource asset and assign a newly created custom Resource class as a script to it.

There's an editor setting default_float_step. It should be raised to 0.0001 in this case.

This fixes the value view in Editor indeed, thank you for that.

Anyway, it still feels like a bug. First of all, why would step value influence a view of a value in the Editor? The leftmost position of a slider should represent the minimum possible value of the field, in my opinion.

Let me know what you think.

You can also fix the problem by specifying the step in the hint string: "0.0001,1,0.0001,or_greater" if you don't want more precision than 0.0001.

The current mechanism of default step does cause some confusion. See also https://github.com/godotengine/godot-proposals/issues/3524
