DeSmuMEの3Dレンダラの行列をLuaからいじれるようにするhack

21:48

(2015年にやったものを発掘して記事にしているのでもう細部を忘れています)

ゲーム内の処理とか一切触らずにこんな風に斜めから映したり、街の全体像を映したりできます。

(建物の一部が映ってなかったり、キャラクターの位置がずれているのはすでに修正済みのバグだった気がします)

EmuLuaにemu.extramatrixmul(), emu.extramatrixproj()という関数を用意しています。

それを使ってたとえばこんな風に書きます。

function translate(x, y, z)
	emu.extramatrixmul({1, 0, 0, 0, 0, 1, 0, 0, 0, 0, 1, 0, x, y, z, 1})
end

function rotateY(theta)
	local c = math.cos(theta)
	local s = math.sin(theta)
	emu.extramatrixmul({c, 0, s, 0, 0, 1, 0, 0,-s, 0, c, 0, 0, 0, 0, 1})
end

function rotateX(theta)
	local c = math.cos(theta)
	local s = math.sin(theta)
	emu.extramatrixmul({1, 0, 0, 0, 0, c,-s, 0, 0, s, c, 0, 0, 0, 0, 1})
end

function scale(k)
	emu.extramatrixmul({k, 0, 0, 0, 0, k, 0, 0, 0, 0, k, 0, 0, 0, 0, 1})
end

function proj(scalar, x, y, z)
	emu.extramatrixproj({scalar, 0, 0, 0, 0, scalar, 0, 0, 0, 0, 1, 0, x, y, z, 1})
end

emu.registerbefore(function ()
	emu.extramatrixinit()
	translate(-200, 0, 0)
	rotateY(0.5)
	scale(0.6)
	proj(1/2,0,0, 0)
end)

DeSmuMEのソースコードdiffです。

元のなったDeSmuMEのリビジョンは忘れました(
