    Unity3D跨屏幕、全屏顯示方法,運(yùn)行環(huán)境:Win10 64bit, Unity3D 2017.3.1

    上面這個(gè)腳本,可以使Unity3D窗口全屏,沒有標(biāo)題欄,通過更改screenPosition的值,還可以使窗口直接在第二個(gè)屏幕上啟動(dòng)(x=0, y=0, width=1920, height=1080),或者窗口跨越兩個(gè)屏(x=0, y=0, width=3840, height=1080)。 如果使用讀取配置文件的方法, 可以自定義屏幕分辨率。Windows系統(tǒng)會(huì)記錄軟件的窗口大小和位置,并記錄在注冊(cè)表的\HKEY_CURRENT_USER\Software\xxx\yyy 位置,xxx是Unity3D在build設(shè)置中的Company Name,yyy是在Build設(shè)置中的Product Name。所以如果有時(shí)候窗口大小有問題,可以先備份注冊(cè)表,再刪除xxx項(xiàng)。建議每個(gè)項(xiàng)目的Product Name不要用默認(rèn)值,否則打包出來的軟件都會(huì)對(duì)應(yīng)到注冊(cè)表里相同的項(xiàng)。
