    Scroll Wheel

    Implemented

    This feature is fully implemented.

    Scroll wheel input via a GLFW scroll callback, exposed to C# as an accumulator that can be read and reset each frame.

    API

    float scrollX, scrollY;
NativeBridge.GetScrollOffset(out scrollX, out scrollY);
NativeBridge.ResetScrollOffset();

// scrollY > 0 = scroll up, scrollY < 0 = scroll down

    NativeBridge Methods

    MethodDescription
    void GetScrollOffset(out float x, out float y)Read accumulated scroll delta since last reset
    void ResetScrollOffset()Reset the scroll accumulator to zero

    Implementation Details

    • GLFW scroll callback accumulates offsets in the C++ renderer
    • GetScrollOffset reads the accumulated value; ResetScrollOffset clears it
    • Used by CameraFollowSystem for third-person camera zoom (scroll up = zoom in, scroll down = zoom out)
    • Zoom distance is clamped between Camera.MinDistance and Camera.MaxDistance
