HalfGridSnap

HalfGridSnap | English Description

Allows snapping coordinates to "half grid points". This plug-in replaces the hard-coded constants of PlanetGrid in the game through Harmony Transpiler, thereby changing the grid adsorption spacing and achieving a half-grid adsorption effect.

Main functions

• Replaced hardcoded constant 5.0f in PlanetGrid with 10.0f, changing snap spacing to achieve half-grid behavior.
• Switch half-grid adsorption by pressing the default shortcut key ~ during runtime (enabled by default). The shortcut key can be customized through the game.

Install

• Directly copy the output DLL to BepInEx/plugins or import the zip compressed package in the Output directory through the module manager for installation.

Build from source

• Use an SDK/Visual Studio that supports .NET Standard 2.1 (e.g. Visual Studio 2026).
• Restore the NuGet package or manually reference the BepInEx and HarmonyLib assemblies (the references should already be in the project).
• Edit the GameDir in the project.csproj to be your actual game directory.
• Select Release/Debug in the solution and generate the project:
• Visual Studio: Open the solution -> Right-click the project -> __Build__.

Implementation Notes (Developer)

• The key implementation is in PlanetGridPatch.cs:
• Use HarmonyTranspiler to loop through the IL instructions, find ldc.r4 5.0, and replace it with ldc.r4 10.0.
• After this modification, the adsorption behavior of PlanetGrid will be calculated with new constants to achieve the desired adsorption effect.
