Random Sliva Jumpscare
by Srula
Random Sliva Jumpscare adds a full-screen screamer that can pop up at random during play, with its frequency and duration set in the mod's options.
What it does
Random full-screen scares appear at unpredictable moments while the game is running, covering the screen for a short time before they disappear. The chance of a jumpscare is set per tick and the length is set in ticks, so players can make the scares rare or frequent and brief or long. The default settings show a scare with a small chance on each tick and keep it on screen for 40 ticks, which is 2 seconds, while 20 ticks equal 1 second.
The mod is a Fabric client mod for 1.21.11, built as a joke in the style of the Random Foxy Jumpscare mod for The Binding of Isaac. It needs Cloth Config API for its settings screen, Fabric API and Mod Menu. Only the client needs it, so servers run without it. It is released under the MIT License and is not open source.
