I have still been learning the in and outs of Unity for the past few weeks. I've been thinking that because I have not been making any regular posts on this site that I would start posting a series of quick unity tips as I learn of them.
Tip #1 - Prevent config dialog from showing when running your compiled game.
When you build your unity game using "File -> Build & Run" and then run the *.exe that was generated you will see a dialog pop up.
To prevent the configuration window from being shown select "File -> Build Settings..." in unity and click the "Player Settings" button at the bottom of the window. The Unity inspector window will contain a number of options. Find the drop down titled "Display Resolution Dialog" and set it to "Disabled". Rebuild your game and run the generated *.exe. No more dialog pop up!
