Shift2Speed - Stardew Valley Mod

Lightweight Stardew Valley mod allowing players to use the Left Shift key to run.

A basic Stardew Valley mod that repurposes the Left Shift key into a dedicated sprint button, rather than the vanilla slow walking behaviour. This mod was built using C# as a personal quality of life improvement to the game as well as a learning project to deepen my understanding of SMAPI and Stardew Valley's internal movement logic.

Tech Stack:

• C#
• SMAPI (Stardew Modding API)
• HarmonyLib (method patching)
• Stardew Valley internal game logic
• Visual Studio

Features:

• Fully replaces the original slow-walking mechanic
• Harmony postfix patch on Farmer.getMovementSpeed()
• Holding Left Shift down increases player speed to 8
• Releasing Left Shift returns the player speed to 5

Skills Gained:

• Navigating and understanding Stardew Valley's internal class structure
• Working with existing game values (speed) and overriding them safely
• Applied Transferrable Java knowledge to C# mod development
• Using Harmony patches to safely modify the game's behaviour
• Understanding how SMAPI loads mods and events

How To Use:

Dependencies: Stardew Valley, SMAPI

1. Install SMAPI
2. Download/clone this mod
3. Place the mod folder into Stardew Valley 'Mods' directory
