"Ignore specific Library"/ VS2008
|
I have an old project I recently wanted to bring over to VS2008... haven't compiled it in about three years.
It compiled fine on my old XP laptop; but I'm finding some weird behavior with the linker.
Basically, I have specific .lib files i... |

MySQL = OPTIMIZE TABLE

I made a boo-boo... maybe.
On a vBulletin forum where I act as an admin (not an owner), I ran an OPTIMIZE TABLE command from the control panel.
Over an hour later, I'm still waiting for the response.
In the meantime, the server is not respon... |

Max Blend/offscreen RenderTarget(2D) in XNA?

Hello,
I've gone over Drilian's fantastic article on lightning, and am having a bit of trouble getting the same sort of effect in XNA.
I've gotten this with anti-aliasing and alpha blended lightning segments:

Recommendations? How to: Flip/Mirror screen without disturbing the HUD
|
Hi Guys
I've been looking into ways of flipping the screen or mirroring the screen during play (as an effect)... I'm not 100% sure how to do it, but it's probably something to do with the projection matrix.
I don't want to flip the hud (if at... |

Sweep and Prune updating sprite positions on the fly

Hello,
We're creating a 2D platformer w/parallax scrolling, and have run into performance issues for the XBOX 360/XNA.
We've tried using Zones or Quadrants, which does improve performance (breaking a level up into pieces and doing the collisi... |

[C#] Generic Functions (a different question)
|
It seems C# doesn't handle generics like C++ handles templates.
I need a way to do this:
public void DoSomething<T>(object o, T thing)
{
_member = thing.Value;
}
The error is 'T' does not contain a definition for 'Value'...... |

dpi vs. screen resolution
|
Hi Guys,
We're doing a 2D platformer game project as a group; we currently have a main player sprite that is about 0.8 inches high, or 90px at 72dpi. We would like to keep the player at the same physical size but up the resolution, say to 200dpi... |

HRGN equivalent for XNA/C#
|
This would be used for better collision detection.
Is there something like HRGN in XNA? Or, would I have to roll my own Region class, with such functions "Contains" and "Intersects"?
Hopefully there's something already.
Thanks and Greetz

Collision detection loop == better than O(n^2)?
|
Hi,
I'm trying to implement a more efficient 2D collision detection routine...
Right now, the routine isn't scalable, meaning that for every sprite I add, you have to add as many collision detection "if/thens" as you have sprites.
In other w... |

deleting a file (C#) (sharing/etc) [resolved]

Hi,
I'm running up against a dumb problem. It's probably a threading issue... but I need to find a way to discover whether another process is using a file before deleting it.
System.IO.File.Delete("Filename") works most of the time, but occas... |

"Ignore specific Library"/ VS2008

Well, of course it ended up being what I thought... something compiled with the wrong flag... but not any of my code.
I was using a version of the Loki library that had one or two projects set to MDd (not MTd) for some reason... don't know wh... |

MySQL = OPTIMIZE TABLE

OPTIMIZE TABLE does a defragment.
Yeah, like I said... no access to the server so no way to restart MySQL.

Sure, you could do that with a RenderTarget2D. You basically just create it when you initialize your graphics stuff, set it as the current RenderTarget using GraphicsDevice.SetRenderTarget (use index 0), and then draw wha... |

Recommendations? How to: Flip/Mirror screen without disturbing the HUD

All right, I was able to get close to solving this using a RenderTarget.
My only concern now is being able to get everything to render to a specific portion of the render target, so that I can spin the render target about an axis.
I mean,... |

I think the problem with the previous code is that it's taking the width and height (extents) of the sprite batch, and rotating around that (the Translation matrix is sent to SpriteBatch.Draw)
I'm just trying to rotate the viewing rectangle, witho... |

Okay, here's what I have for trying to get things at least rotated around the center of the screen.
Problem is, it doesn't seem to be working. It seems to be trying to rotate around some outer point I can't find.
Assume ZoomPercentage = 1.0f... |

I can't even compute 1+1 right now, but wouldn't you just swap left and right for your projection matrix (assuming you use a perspective)?
Also you could do all kind of nice effects by rendering to a texture first...

You can constrain your generic types to specific interfaces, so you could define an interface for types that expose Value and then call it on that.

Hi Mike,
Thanks for your reply. Currently I can't refactor the types to expose an interface, as the code was written by another person in the company and generally under their watch.

So a 250px image would have to be scaled a certain percentage (by XNA) to be seen at the same size on screen.
Thanks for the explanation.
Yep. Now you're cooking with fire =)... |
