room_set_viewport

描述

With this function you can set the view port properties for any room in your game except the current one. You supply the room index to set the view port in, the view port index (from 0 to 7) and then whether the view port should be visible at the start of the room or not (set to true to make the port visible, and false otherwise). After that you set the x and y coordinate (corresponding to the top left position of the view port) and then the width and height in pixels.

语法：

room_set_viewport(rm, vind, vis, xport, yport, wport, hport);
