Mobile phone adaptation problem

I have a demand that has puzzled me for a long time, because browsing the canvas on the mobile phone is proportionally scaled. How to rotate the entire canvas engine canvas on the mobile phone screen into a horizontal screen display, so that it can be larger to fit the mobile phone screen

Hi @guohao,

If you set the Fille Mode to Fill window in your project rendering settings, then that will happen automatically. The canvas will always resize to fit the window:
