Disable certain effects when snowing

[drunkwinter]

Changes:

• Disables rain-related audio (e.g., surface impacts)
• Disables wetness-related effects (e.g., reflections, footstep/vehicle interaction sounds, particles)

Todo:

• Add pre-CE patterns (Credit: @RecklessGlue540)

I think it would be better to use mid hook instead of raw mem. If you're not sure how to implement that, I can do it later.

I first wanted to use mid hooks, but then thought that was maybe a bit overkill. But sure I can change it in a moment.

Maybe @RecklessGlue540 can help with patterns.

@drunkwinter Here are the adapted hooks:

// Disables rain-related audio (e.g. Surface impacts)
auto pattern = hook::pattern("F3 0F 10 05 ? ? ? ? F3 0F 11 04 24 E8 ? ? ? ? 51");
if (!pattern.empty())
{
    static auto SetRainAudioHook = safetyhook::create_mid(pattern.get_first(8), [](SafetyHookContext& ctx)
    {
        if (enabled)
        {
            ctx.xmm0.f32[0] = 0.0f;
        }
    });
}
else
{
    pattern = hook::pattern("D9 1C 24 E8 ? ? ? ? 51 D9 1C 24 E8 ? ? ? ? D8 44 24 08 83 C4 04 5E 59 C3 CC");
    static auto SetRainAudioHook = safetyhook::create_mid(pattern.get_first(3), [](SafetyHookContext& ctx)
    {
        if (enabled)
        {
            *(float*)ctx.esp = 0.0f;
        }
    });
}

// Disables wetness-related effects (e.g. Reflections, footstep/vehicle interaction sounds, particles)
pattern = hook::pattern("C7 05 ? ? ? ? 00 00 80 3F F3 0F 10 25 ? ? ? ? F3 0F 10 04");
if (!pattern.empty())
{
    pWetness = *reinterpret_cast<float**>(pattern.get_first(2));
    static auto SetRainWetnessHook = safetyhook::create_mid(pattern.get_first(10), [](SafetyHookContext& ctx)
    {
        if (enabled)
        {
            *pWetness = 0.0f;
        }
    });
}
else
{
    pattern = hook::pattern("F3 0F 11 05 ? ? ? ? EB 67");
    pWetness = *reinterpret_cast<float**>(pattern.get_first(4));
    injector::MakeNOP(pattern.get_first(0), 8, true);
    static auto SetRainWetnessHook = safetyhook::create_mid(pattern.get_first(0), [](SafetyHookContext& ctx)
    {
        *pWetness = 1.0f;

        if (enabled)
        {
            *pWetness = 0.0f;
        }
    });
}

@RecklessGlue540 Thanks! Btw what is the best way to downgrade to a pre-CE version?

Btw what is the best way to downgrade to a pre-CE version?

I would recommend to get a hold of official files if possible and downgrade manually
But alternatively, ClonkAndre's archive from here is not too far from that: https://mega.nz/folder/Fn0Q3LhY#_0t1VZQFuQX22lMxRZNB1A

Make a copy of your IV folder without mods, download just the 1080.zip from there and paste its contents over the new folder.
Then download the latest build of FF + the legacy addon and paste both over as well and that should be it.
I tested this way myself just now.
