Monogame freezes when dragging the game window

[Oscar_Santos]

Hi, Im new to Monogame.

I try to do a simple Window (drawing randow rect) with Shared project DesktopGL with Monogame 3.7.1

When I move the window, Monogame freeze a game.

I try to apply solutions that i found in stackoverflow and in this comunity site without success (clone git repo and try to build and found many errors).

|Error|CS2001|Source file ‘\MonoGame.Framework…\ThirdParty\NVorbis\NVorbis\BufferedReadStream.cs’ could not be found.|MonoGame.Framework.WindowsGL|\MonoGame-master\MonoGame.Framework\CSC|1|Active|

Can anyone help me to solve this issue?

Thanks in advance.

pd: Sorry for my English.

Im not 100% on this but i believe

1. update continues to execute when dragging.

2. draw doesn’t

3. Monogame does that on purpose as a choice for reasons which i forget exactly why.

Hi @Oscar_Santos, Welcome to the forum!

Read here:

(SOLVED) Won't update parts of game window that are outside of Monitor bounds

The Windows message pump behaves differently when the window is being dragged around because the drag operation is modal. You have to write extra code to try to work-around it, but it makes the window move or resize far less efficient because the redrawing is happening.

Another good read:

Monogame freezes when dragging the game window

I haven’t seen an obvious solution to this and wanted to see what others have done to get around it (here’s the last conversation I saw around it: Monogame github issue I am doing a network/multiplayer game and when a user drags the game window the Update/Draw methods pause until they release the window. This de-syncs the game from the server temporarily which is a problem for a serious multiplayer game. Is there any way around this?

I would suggest keeping your draw code and positioning code separate and resume update from updated positions instead of pushing draw calls, probably a better idea to detect drag behaviour to pause draw calls but keep movement going.

Games like FTL manage this pretty well with the option to pause the game when it is detected that the mouse is outside of the game window.

Working around it is a better option.

A good thing to do is use both your normal language and English, but do let us know you speak Spanish and not Portuguese or something so that we can translate faster by not having to guess what language you are speaking to help better.

Happy Coding!
