Can't update old save

  • ivel236     15th Jul 2022 Member 0 Permalink
    (In regard to the other threads I am seeing this is not related to the 404 issue, this is a 2012 save I have tried to update multiple times over the years)

    One of the updates destroyed the pipes in one of my old saves.
    I have tried to update it a few times with fixed pipes but everytime I re-save it just makes a new one and doesnt overwrite the old one. Is this a bug? I have tried to resave some other old saves and it worked fine and kept the same ID. Even if I make no edits, trying to save will just generate a new ID.

    Save in question: id:741610 *Pardon my 12 year old english.

    I might attempt later to track the version it is from down and reupload from that. It was made close to the water equaliztion update, which might be why its glitched.

    Also while anyone is here do you remember what element has the property of allowing you to add the velocities of PHOT particles together like vector muliplication? Was it C5 on a certain TMP setting?

    If you look at the machine-friendly version of the save info, you can see that the title actually has a leading space. Can you try adding one to the update candidate's title?

    EDIT: It seems the new save upload code on the server side trims spaces on the ends >_> I'll see if I can get someone to remove the space from the old one's title.

    Haha_TPT_git_rekt_by_a_space._What_are_you_a_commodore_64?

    That would be great LBPHacker thanks.

    Btw yeah it's C5, no special tmp value required. You just give it two photons and it gives you back one with the sum of the velocity of the originals. It's actually vector addition though.

    Have you ever dabbled with antialiasing?
    I was thinking the C5 thing might be useful.
    I wanted to make a nice temp plotter that can fit all 10,000 temps in steps of 10 with only 100 vertical Y positions using some sort of antialiasing. Most of the algorithms seem pretty division intensive so even the best TPT electronics couldn't do it at 60hz...

    Although a god like you could probably pull it off.

    Anti-aliasing or merely line drawing? If line drawing, there's Bresenham's algo, which doesn't use division. If anti-aliasing, Xiaolin Wu's algo is a spin on Bresenham's but with anti-aliasing.

    yeah Xiaolins algo looks perfect. Just trying to squeeze some extra depth in the temp grapher for my next destroyable fusion/warp reactor, since it can reach 9000C° and I don't have alot of space to plot it.

    Thanks again LBP you are too helpful!
