XNA Game with MonoGame on Mac
I have solved this by adding the Tao.sdl.dll file to the project and adding in a .net reference for the project. Thanks for the help ...
When I pass a Texture2D as parameter to a class, this texture is null
LoadContent is called by XNA after your MainMenuScreen is initialized. You may have to defer the usage of your playGame object to the moment when the texture is loaded or initialize your MenuEntries in the LoadContent.
Tile tearing with float positioning, MonoGame
Try moving a camera instead of moving your tiles. The camera can move a floating point values, and your tiles will not have tearing because the are a fixed positions. Here's an example of how I render a tilemap in an old game of mine. I haven't posted every structure...
Xamarin using cross platform 3D engine
xamarin,xna,cross-platform,monogame
Monogame is an open source implementation of the XNA API. It uses the same classes and namespace than XNA but it is a new implementation that is cross-platform. It used to require the XNA framework for its content pipeline tool. But since version 3.3, Monogame provides its own tool so...

Answer: in the new Vector2(x, y) I just had to set x and y values that are within the image.
SimplexNoise terrain in MonoGame

Check line 133 in the SimplexNoise you are using: // The result is scaled to return values in the interval [-1,1]. After you divide it by 10, the result would be in range from -0.1 to +0.1 You need a range from 0 to 1, so instead of dividing by...
How to divide Vector2 to Vector2 Arrays?
How about something like this: // For N waypoints between a start and end, we need N+1 segments segments = WaypointAmount + 1; xSeg = (end.x - start.x) / segments; ySeg = (end.y - start.y) / segments; // even though we have N+1 segments, adding the last segment would take...
MonoGame renderTarget2D Error
The resolution of your RenderTarget2D may be the problem. I have noticed this needs to be a multiple of 4 when using SharpDX but I can't find any documentation to back this up. Try using 1280x720 rather than 1281x721....
Monogame sprite alpha blending
c#,monogame,alphablending,spritebatch
Try this: spriteBatch.Draw(Tex2D, TargetRec, new Color(Color.White) * weight[x,y]); This is the proper way to draw things transparently when SpriteBatch is using premultiplication. The alpha channel works differently when drawing with premultiplication. The basic change you need to make is to multiply the color by the transparency instead of setting the...
Create a big image out of several other small images in MonoGame
You can render different textures into one using RenderTarget2D _renderTarget = new RenderTarget2D(GraphicsDevice, (int)size.X, (int)size.Y); GraphicsDevice.SetRenderTarget(_renderTarget); GraphicsDevice.Clear(Color.Transparent); SpriteBatch.Begin(SpriteSortMode.Immediate, BlendState.Opaque); //draw some stuff.

Rectangle's width increasing more than it should while trying to resize the rectangle
Fixed by adding: value.Replace("\n", "") in temp = parseText(value, Size.Width); I was doing that before the while loop, but not inside it. Therefore, the text was getting a bunch of new lines, and when it got called again, the new lines disappeared before the while loop. It should look like...
How to use Xna Content Compiler on visual studio 2013
c#,xna,visual-studio-2013,monogame
Another rather classic solution is to install XNA framework included in Windows Phone SDK 7, create a separate XNA solution just for the purpose of building XNB files. To get XNA working on your computer (for VS2010 - VS2013) first download Windows Phone SDK 7 and 8 (both of them)...
Function of base.Update and base.Draw in Monogame?
Accordingly to the source code of MonoGame linked by Dylan Wilson, the Update and Draw methods from the base class Game just called Update(...) and Draw(...) on a each element of a filtered GameComponentCollection, a Collection of IGameComponent. IGameComponent is an interface that show how XNA and Monogame want you...
Foreach statement does not contain public definition for getEnumerator
c#,collision,monogame,enumerator
The error is because paddle1 is of type Player, not an IEnumerable. If you only have two players, you shouldn't have to loop and can just implement your function like this: public void CollisionDetection(Player firstPlayer, Player secondPlayer) { firstPlayer.Update(gameTime); secondPlayer.Update(gameTime); if (firstPlayer.CollisionSprite(secondPlayer)) { firstPlayer.Velocity = -firstPlayer.Velocity; secondPlayer.Velocity = -secondPlayer.Velocity; }...
Ubuntu - MonoGame static graphics.Viewport size

So, I still don't know what was causing the problem, but I managed to avoid it. I was trying to get graphics.Viewport.Width graphics.Viewport.Height in a protected override void LoadContent() function. That's where the values were wrong. I tested some options and it came out that in the game class constructor,...
How do I can set a fixed play area in xaml monogame?
c#,xaml,windows-store-apps,monogame
You can set multiple render targets to draw to for your sprite batch. I would make your entire gameplay logic or area be drawn as or return a Texture2D at the desired size. Then in your Game1.cs or where ever, you position that texture accordingly in additional to the UI...

drawString not drawing text on my game
monogame,drawstring,spritebatch
You should start by removing any other draw calls. If you can then see the string, it means that the string is being rendered behind something else. Then you need to play with layerDepth values (from 0.0 to 1.0 where 1.0 is the front)

NuGet package contains assembly with the same name as an assembly in another package

The MonoGame.Binaries NuGet package adds a reference to OpenTK.dll from its MonoGame.Binaries.targets that it adds to your project. This .targets file is in one of the packages\MonoGame.Binaries.3.2.0\build subdirectories depending on the project's target framework which in your case is net40. If you remove the following section from the MonoGame.Binaries.targets file...

Xamarin Signed Release apk will install but not run

Monogame audio not working

2D Monogame: Rectangle collision detection, side specific
The Rectangle class in XNA has 4 properties that can be of use here: Left, Top, Right and Bottom. You can use these to determine which side(s) the collision took place from. For example, consider the Player.Rectangle.Left > Map.Rectangle.Left. If this is true, then the collision could have ocurred on...
Creating a Tooltip rectangle and checking when the rectangle leaves the screen

Is it possible to get “contextual” gestures in Monogame/XNA?
c#,gesture,multi-touch,monogame
That feature is not built in to MonoGame, as it is not part of original XNA. Essentially you'd want more than one 'logical' TouchPanel defined by its sub-rectangle of the window. However TouchPanel is static, hence there is only one for the whole game in default XNA. The good news...

Sub pixel movement need 1 transparent pixel on the edge to move smooth
Texture border colors were created for precisely this sort of situation. The basic idea is that you can replace certain texel fetch operations (those outside the normalized range [0.0,1.0]) with a constant color. Border colors work for texture filtering too, which may implicitly fetch a neighbor texel outside the normalized...
