I will post some code snippets which someone might find useful here from time to time. They can be used within MonoGame and maybe in other projects if they don't include XNA-specific code.

First I want to link my sprite animation tutorial: https://forums.tigsource.com/index.php?topic=58912.0.

Maybe you wondered how to center drawn strings on the game screen. I will tell you:

You first have to import a font (you have to create the font via the MonoGame Pipeline):

Code:

SpriteFont font = Content.Load<SpriteFont>("font");

Simply put this code in your class in the Draw() method (I will use the standard objects which are generated by MonoGame):

Code:

string str = "Text";

spriteBatch.DrawString(font, str, new Vector2((GraphicsDevice.Viewport.Width / 2) - (int)(font.MeasureString(str).X / 2), (GraphicsDevice.Viewport.Height / 2) - (int)(font.MeasureString(str).Y / 2), Color.Black);

Does anyone remember how to disable filtering when generating text? I remember doing this years ago but I've forgotten how.

Does anyone remember how to disable filtering when generating text? I remember doing this years ago but I've forgotten how.

Try

Code:

Game1.GraphicsDevice.RenderState.MultiSampleAntiAlias = false;

[InfiniteStateMachine]

I did give that and various other alias setting a try but that didn't seem to do it. I think it's because the problem is the content processor is antialiasing the text when it renders it to a texture. Thanks for the advice though.

I'll try to dig up my old code and see what I did because I'm quite certain I solved this in the past.

Maybe you have to open the MonoGame Content file (Content.mgcb in the directory Content) and set there the value of the variable that causes the antialising in your sprite font or texture to false. So it will build the font or texture without antialising.

Doesnt seem like the application exposes a variable for scaling/sampling.

EDIT : If I open the stpritefont file with a text editor I can find more stuff. Upping the size helps a bit.

This thread seems to indicate other's have had problems.

EDITEDIT : If I switch to a font and use a specific size or multiple of that size the issue is fine. Maybe it uses a different scaling filter depending on the situation.

Play music and sounds

To make this working you have first to add a music file (I have called it "file.mp3") to your content folder via the MonoGame Pipeline. After you have done this, add following line to your class where you want to use the music/sounds:

Code:

using Microsoft.Xna.Framework.Media;

Then you have to load the song:
Add following:
To your fields/properties:

Code:

Song song;

and

Code:

bool IsPlaying = false;

To the LoadContent method:

Code:

 song = content.Load<Song>("file");

To specify if you want to loop the music, you have to add

Code:

MediaPlayer.IsRepeating = true;

Now you can start playing your music in the Update() or Draw() method with following code:

Code:

if (IsPlaying == false)
{
    MediaPlayer.Play(song);
    IsPlaying = true;
}

To pause the music add

Code:

MediaPlayer.Pause();

To resume add

Code:

MediaPlayer.Resume();

And to stop playing add

Code:

MediaPlayer.Stop();

[_glitch]

It's not only for MonoGame, but in my opinion it's useful sometimes:

Instead of this

Code:

bool _Bool = true;

if (_Bool == true)
    _Bool = false;
else
    _Bool = true;

you can say

Code:

_Bool ^= true

[ThemsAllTook]

_Bool = !_Bool; is how I usually see that done, but I suppose that way works too.

[_glitch]

Yes, your way is probably more readable and available in more programming languages.

Me too, but it can be a bit redundant and verbose if the name of the variable is long. Would be cool to have some kind of unary !! operator or something, like ++ and --. I've toyed with that for my language design which is never going to actually happen but is fun to play with. c;

Or, if the name of the variable is strange. Not to long ago I had a variable called 'exa'. At some point I wrote '!exa', but i read 'lexa' and wondered why my variable has gone.
