UDK Gems

[Mougli]

I haven't seen anyone talking about that on the forums, so I thought I'd draw your attention to the following:

Epic has recently started to write some interesting tutorials on specific topics (such as using the mouse in game) on UDN.

The URL is here: http://udn.epicgames.com/Three/DevelopmentKitGems.html

Yeah! We're trying to hit some interesting topics in a more practical application sort of way. James has been doing an awesome job on those. I've been tweeting about some of them, but I guess I forgot to post about them on the forums. Ooops! Good thing we have awesome members like Mougli to pick up the slack when I drop the ball.

I'm going to sticky this thread and I'll try to post here with updates as new ones are added.

[UnrealEverything]

Thanks! ...would have missed some interesting topics there otherwise!

I am waiting for more

[daimaku]

thanks for the information, i have missed that !!!! very good !!!!

[mktwo]

Very interesting! Was wondering how you'd implement actor selection brackets!

Thanks a ton! this is exactly the type of tutorials we need, hope to see more in the future...

[Jestersheepy]

Would be awesome if we could do a pole to 'most wanted tutorial' that way these tutorials would be put to optimal use?

Either way, awesome I will be looking closely at these.

Found one error in the mouse interface(http://udn.epicgames.com/Three/Devel...Interface.html)
Im running december version, and im not sure if this is an error or something i havent learned, but in MouseInterfaceHUD, you need to add a local PlayerInput object like so:

class MyHud extends HUD;

// The texture which represents the cursor on the screen
var const Texture2D CursorTexture; 
// The color of the cursor
var const Color CursorColor;
var MyPlayerInput next;
event PostRender()
{
  // Ensure that we have a valid PlayerOwner and CursorTexture
  if (PlayerOwner != None && CursorTexture != None) 
  {
    // Cast to get the MyPlayerInput
    next = MyPlayerInput(PlayerOwner.PlayerInput); 

    if (next != None)
    {
      // Set the canvas position to the mouse position
      Canvas.SetPos(next.MousePosition.X, next.MousePosition.Y); 
      // Set the cursor color
      Canvas.DrawColor = CursorColor;
      // Draw the texture on the screen
      Canvas.DrawTile(CursorTexture, CursorTexture.SizeX, CursorTexture.SizeY, 0.f, 0.f, CursorTexture.SizeX, CursorTexture.SizeY,, true);
    }
  }

  Super.PostRender();
}

defaultproperties
{
  CursorColor=(R=255,G=255,B=255,A=255)
  CursorTexture=Texture2D'EngineResources.Cursors.Arrow'
  Name="Default__MyHud"
}

It does look like a local variable is missing in the first example. I passed it on to be looked into and fixed. One way or another it should be corrected by tomorrow.

Thanks!

[Froyok]

Thanks for the link, like others, I've missed the page on the UDN. Very usefull !

[Solid Snake]

Whoops. Yeah, looks like I deleted the local variable declaration by mistake. Will update the page when I can.

[MonsOlympus]

Im pretty sure at that point in the tutorial you havent yet defined a custom player input class as well, not sure if thats on purpose but as you go down both are shown again and are correct

[Solid Snake]

Yeah, it did jump a little ahead. But I sort of ranked it based on importance vs compile order. Oh well, hopefully people still sort of get what I intended.
