How would you go about resizing a games screen?

[xCyberFang]

I have a game for windows that has a big screen size and whatnot, and i want to be able to resize it down to 240x320. i would go through and edit the values to make them align, but theres ALOT of values to edit.

is there any way i could possibly have the game drawed then the screen itself resized? like similar to how the screen can be rotated to horizontal view??

I think this is what you are talking about:

public Game1()
{
graphics = new GraphicsDeviceManager(this);
Content.RootDirectory = "Content";
graphics.PreferredBackBufferHeight = 320;
graphics.PreferredBackBufferWidth = 240;
}

Nah, that resizes the screen itself. but it doesnt scale the games drawings any.

You would need to have a scale factor. You can figure out that factor mathematically by determining the ratio of large size: 240x320. In the draw method, you can specify a scale.

[xCyberFang]

yeah, i can easily get the scaled size of the current window, but im just wondering what is the code i would use??

The current size is 480x640, which itself is 240x320 in scale..

How would i go about doing the scaling itself??

[Red Sky]

Your scale factor would be .5, so you would just use the .5 in your draw method.

Check out the different draw methods, I can't remember off the top of my head.

[xCyberFang]

ya. .5, i know. but how would i go about doing this? or where can i find a code.

i know i just dont throw in .5 in the draw lol.

It's really not that hard... it's part of the draw method. There's a argument for scale. You put that scale in and BAM it just works.

If your planning on drawing the entire game to 800x600 then downsizing it to 240x320 then you're gonna get a big performance hit and the zune doesn't scale pictures smoothly so it will also look like poop.

Yeah, you got the idea, how exactly would i go about this? like can you give an example that i could work off of (it doesn't need to work or build or whatever, i just want one i can see how i can go about doing this).


The truth behind this is i found a working open source xna pacman copy and i was wanting to attempt to scale it down, i tried resizing it, but there are alot of variables to resize and rather kind of hard, so im wanting to try to scale the screen itself, rather than the components.

I had to remove the sound files which were in xact, and the button input is kind of complex but i think i am getting somewhere, other than those things, i just need help getting it down to 320x240

Theres the link if you guys would like to see it, and maybe even challenge yourself to attempt to port it to zunes.

batch.Begin(SpriteBlendMode.AlphaBlend, SpriteSortMode.Deferred, SaveStateMode.None, Matrix.Identity * Matrix.CreateScale(scale));
