Curve in Godot 4.4 beta 3 clamps values to [0,1]

[h-skibbe]

Tested versions

• Was fine with Godot 4.3 (stable)
• Values seem to be clamped to [0,1] with Godot 4.4 beta 3 (same project)

System information

Godot v4.4.beta3 - Ubuntu 24.04.1 LTS 24.04 on X11 - X11 display driver, Multi-window, 1 monitor - Vulkan (Forward+) - dedicated NVIDIA RTX A5000 Laptop GPU - 12th Gen Intel(R) Core(TM) i7-12700 (20 threads)

Issue description

Curve : it seems like values are being clamped to the interval [0,1] in Godot 4.4.

Best,

henrik

Steps to reproduce

var testcurve = Curve.new()
testcurve.clear_points()
testcurve.add_point(Vector2(0,-1))
testcurve.add_point(Vector2(0.1,0.0))
testcurve.add_point(Vector2(0.2,0.2))
testcurve.add_point(Vector2(0.8,0.9))
testcurve.add_point(Vector2(1.0,2))
testcurve.bake()

for i in range(0, 11):
	var x = i / 10.
	var y = testcurve.sample(x)
	print(Vector2(x, y))


##### Output Godot 4.3 : #####

This was an intentional change:

• Extend Curve to allow for domains outside of [0, 1]. #67857

You need to update the min/max_value range to include your range, this wasn't enforced in 4.3

Noted! Thank you very much

Added a suggestion that this change should be mentioned in the "Upgrading from 4.3 to 4.4" page that's being worked on:

• Add "Upgrading from Godot 4.3 to Godot 4.4" page godot-docs#10546
