HSP用 定義

HSP3.7/3.8 は構造体機能が無いため4byte整数配列(dim)+peek/poke で操作(32/64bitでサイズ・位置が異なる場合はタブで分割)。IronHSP は NSTRUCT(#defstruct/stdim/->)で32/64bit共通。

; HSP3.7/3.8 は構造体機能が無いため、4byte整数の配列変数で操作します。(x64 レイアウト)

; RoomHF : INT (+8, 4byte)  st.2 = 値  /  値 = st.2   (lpoke/lpeek も可)
; RoomRolloffFactor : FLOAT (+12, 4byte)  st.3 = 値  /  値 = st.3   (lpoke/lpeek も可)

; HFReference : FLOAT (+48, 4byte)  st.12 = 値  /  値 = st.12   (lpoke/lpeek も可)
; ※4byte境界の整数は添字 st.N(N=オフセット/4)で読み書き可。それ以外は peek/poke 系を使用。
; IronHSP は NSTRUCT(構造体)をサポート。32bit/64bit どちらでも同じコードで動作します。
