  • Multiple Problems Installing 12.04, now can't use Windows

    - by user87997
    First I tried using the 32-bit wubi.exe installer from the main Ubuntu website. It worked fine, dual booted with Windows 7 and all. I tried installing several applications and got errors. After searching for a little while for a fix, I found that someone else had solved the problem by uninstalling the 32-bit version and installing 64-bit Ubuntu. Apparently there is no wubi.exe installer for the 64-bit version, so I used LinuxLive to put the iso file onto a USB drive. I changed my the boot order in BIOS to check the USB first. It did, and I got into the Ubuntu installer just fine. Everything was working fine, but then I got an error that GRUB could not be installed. I chose "install manually later" or something like that. Immediately, the installer said it was done and ready for a reboot. At this point, my USB is still in the computer. The computer reboots...and it's back at the installer for the USB. I look up what's going on here, and someone says in a thread they solved it by selecting "Try Ubuntu" then installing it via a shortcut on the desktop. I assumed that Ubuntu simply hadn't installed and it would be safe to try again, so I did. It finished installing, this time I chose a different partition that wasn't being used. The thread also said to reinstall grub to the mounted drive, so I did that. Next I took out my USB and rebooted. I get stuck on the GRUB GNU loader, v.1.99 or something I believe it says at the top. I can't do anything, and it doesn't detect Windows 7 OR Ubuntu. When I check partitions, I have two 43 GB partitions that both have the same files in them (I'm assuming those are the two Ubuntu installations), and can only run Ubuntu off of my USB-- and can't run Windows 7 at all, however from within Ubuntu the windows 7 filesystem and files can still be seen. I have no idea what to do now. I used Ubuntu in the past (9.xx) and never had these sorts of problems! Please help. And sorry for the wall of text.

  • IndexOutOfRangeException on World.Step after enabling/disabling a Farseer physics body?

    - by WilHall
    Earlier, I posted a question asking how to swap fixtures on the fly in a 2D side-scroller using Farseer Physics Engine. The ultimate goal being that the player's physical body changes when the player is in different states (I.e. standing, walking, jumping, etc). After reading this answer, I changed my approach to the following: Create a physical body for each state when the player is loaded Save those bodies and their corresponding states in parallel lists Swap those physical bodies out when the player state changes (which causes an exception, see below) The following is my function to change states and swap physical bodies: new protected void SetState(object nState) { //If mBody == null, the player is being loaded for the first time if (mBody == null) { mBody = mBodies[mStates.IndexOf(nState)]; mBody.Enabled = true; } else { //Get the body for the given state Body nBody = mBodies[mStates.IndexOf(nState)]; //Enable the new body nBody.Enabled = true; //Disable the current body mBody.Enabled = false; //Copy the current body's attributes to the new one nBody.SetTransform(mBody.Position, mBody.Rotation); nBody.LinearVelocity = mBody.LinearVelocity; nBody.AngularVelocity = mBody.AngularVelocity; mBody = nBody; } base.SetState(nState); } Using the above method causes an IndexOutOfRangeException when calling World.Step: mWorld.Step(Math.Min((float)nGameTime.ElapsedGameTime.TotalSeconds, (1f / 30f))); I found that the problem is related to changing the .Enabled setting on a body. I tried the above function without setting .Enabled, and there was no error thrown. Turning on the debug views, I saw that the bodies were updating positions/rotations/etc properly when the state was changes, but since they were all enabled, they were just colliding wildly with each other. Does Enabling/Disabling a body remove it from the world's body list, which then causes the error because the list is shorter than expected? Update: For such a straightforward issue, I feel this question has not received enough attention. Has anyone else experienced this? Would anyone try a quick test case? I know this issue can be sidestepped - I.e. by not disabling a body during the simulation - but it seems strange that this issue would exist in the first place, especially when I see no mention of it in the documentation for farseer or box2d. I can't find any cases of the issue online where things are more or less kosher, like in my case. Any leads on this would be helpful.

  • Understanding Long Tail Keywords For SEO
