Valheim Wire Patches

Fixes for vanilla Valheim bugs I've found. No gameplay changes.

This mod is meant to be temporary. The fixes are here so people can have them now, and I'm hoping they get added to Valheim Community Patch (GitHub).

Source code: https://github.com/Krosshair/WireMods/tree/main/ValheimWirePatches

Every fix has its own setting, all on by default. Client-side.

Fixes

Double click sound

Inventory tabs and buttons (Craft, Upgrade, Skills, Trophies, Achievements...) play the click sound twice. More noticeable when the game is lagging, like at a big base.

Cause: InventoryGui.SetActiveGroup plays m_setActiveGroupEffects (the sound for switching panels with a controller's bumpers), and the button plays its own ButtonSfx click in the same frame.

Fix: when SetActiveGroup has played its sound this frame, the button's own click is skipped.

Lighting breaking after teleporting

After going through a portal, a dungeon entrance or exit, or loading in, the lighting looks right, then breaks (flat, orange, like everything is lit by the sky) and comes back a few seconds later in a wave spreading out from you.

Cause: lighting and reflections come from two realtime reflection probes (ReflectionUpdate), re-rendered one at a time every 3 seconds where you stand. Anywhere outside both of them falls back to the skybox, which is the broken look. Several things leave you outside both after a teleport:

• The probes are children of an object that follows the player. When a teleport ends, that object jumps to the destination, and a probe that was just rendered at the destination jumps along with it, thousands of meters away. Once the other probe gets re-rendered, nothing covers you until it has grown back.
• Probes keep being rendered during the teleport, before the destination has loaded.
• Short teleports (dungeon doors) end in the same physics step as the player moves, before the reference position (where probes are rendered) has caught up, so the arrival render happens back at the door.

Fix: the probes no longer follow the player (their position is set on every render anyway). No probe renders during a teleport. On arrival one renders where the player stands and shows at once, and another once the distant terrain is rebuilt for the new place.

Lighting stuck on lightning flashes

If a probe renders during a lightning flash, the flash stays baked into the lighting until the next one.

Fix: a render that would land during a flash waits until the flash is over.

Performance

Nothing runs every frame. The fixes only act when you click a button, teleport, spawn, or when lightning flashes, and during a teleport the game renders fewer probes than it normally would.

Disclaimer: the code is AI-assisted since I barely know C#. Not fully AI nor human.

0.1.4

• Works with Valheim Performance Optimizations: its reflection probe replacement is turned off, since it skipped the reflection fixes.
• README: the lighting fixes work with or without Valheim Community Patch, nothing needs turning off there.

0.1.3

• The double click sound fix is off by default now, since Valheim Community Patch has it. Configs that already have it on keep it on.
• README: marked which fixes are in Valheim Community Patch, and that its lighting fixes don't work yet.

0.1.2

• Double click sound fixed at the source: the inventory's buttons no longer ask for the panel switch sound, instead of the button's own click being skipped.

0.1.1

• Icon fixed.

0.1.0

• First release.
• Fix: inventory tabs and buttons played the click sound twice.
• Fix: the lighting broke for a few seconds after portals, dungeon entrances and exits, and loading in.
• Fix: a lightning flash could get stuck in the lighting for a few seconds.
