Smooth GUI

Smooth GUI and loading screen

The Smooth GUI backport animates menu opening and fades in the in-world background. The Loading Progress Bar port restores the green world-loading bar, with the mixin port contributed by kotmatross28729. These features run on the client.

Menu animations

Config category: smooth_gui.

Animation and background fade durations are in milliseconds. BACK adds a small overshoot; CUBIC follows a smooth curve without that bounce. DOWN starts below the screen and moves upward. Exclude individual screens by simple or fully qualified class name when another mod supplies its own animation.

Setting	Default	Range or format	Effect
smoothGuiEnabled	true	true / false	Enable smooth GUI opening animations (slide-in and background fade).
smoothGuiAnimationTime	220	10 to 10000	Animation duration in milliseconds.
smoothGuiAnimationScale	1.0	0.0 to 100.0	Animation intensity multiplier. Higher values = larger displacement.
smoothGuiFadeBackground	true	true / false	Fade in the dark background overlay when opening GUIs in-world.
smoothGuiBackgroundFadeTime	85	1 to 10000	Background fade duration in milliseconds.
smoothGuiAnimationStyle	BACK	BACK, CUBIC	Easing curve for the animation. "BACK" has a slight overshoot bounce, "CUBIC" is a simple smooth curve.
smoothGuiAnimationDirection	DOWN	DOWN, UP	Direction the GUI slides in from. "DOWN" slides up from below, "UP" slides down from above.
smoothGuiExcludedScreens	Default list	List of text entries	GUI screen classes that should not be animated. Can be simple names (e.g. "GuiChat") or fully qualified (e.g. "net.minecraft.client.gui.GuiChat").
