如何在所有监视器和分辨率下使Java游戏中的所有对象保持相同？

Question

I'm a beginner to java and I'm working on my first game :)

For my java game, do I need to position and size everything relative to my monitor settings? for instance

to position and size things, I use Point(x,y)

Shall I rather do "ScaledPoint" where "ScaledPoint" is equal to

public Point ScaledPoint(int x,int y)
{  
 return new Point(x*ScreenWidth/1680,y*ScreenHeight/1050);
}

Since my ScreenWidth and ScreenHeight as I'm developing the game world is 1680*1050 px?

To keep everything the same across different resolutions? I'm not sure what to do.

Answer 1

This is kind of a broad question, but a general principle would be to define your game space in some sort of device-independent coordinates with units small enough to accommodate your expected screen sizes and then some.

Then, scale those coordinates for each display depending on the display size. The scaling factor could possibly be something the user could configure.

The objective here is (as it is in many cases in computer science and software development) to separate the content from its presentation . You work internally in coordinates that are meaningful to you and consistent, and leave the layout on the screen to the presentation layer. This gives you the greatest flexibility and also simplifies the game engine programming since you're not worrying about display resolution at that level, only at the display level.

This principle (separation of concerns) is why we moved from HTML-only in the web's prehistoric era (the 1990s), where HTML dictated both content and layout, to today's HTML+CSS where the HTML specifies the content and CSS can be used to present the information differently for different browsers.
