GLINE can crash SB!?

  • #1 ✎ 168 Nathaniel Avatar Block I didn't change my avatar for 30 days. Website Avatar Embargo I didn't change my avatar for 90 days Website Avatar Taboo I didn't change my avatar for 180 days Website Recently I've discovered that GLINE can crash SmileBASIC in a running program. Here's the code I used: ACLS BGMPLAY 17 ?"Press any button to crash" REPEAT UNTIL BUTTON(2) GLINE 0,1e+9,1,-1e+9 Posted
  • #2 ✎ 477 SquareFingers Interesting bug, it leads to a 3DS system restart, not just SmileBasic closing. And GLINE 0,1e9,0,-1e8 does not trigger it, neither does GLINE 1,1e9,1,-1e8, suggesting it's not the endpoints, it's the slope. And GLINE 1,1e9,0,-1e8 works, suggesting that it's just anticlockwise of vertical, not clockwise of vertical. How bizarre. EDIT: GLINE 1E9,0,-1E9,1 is just, just wierd. I defy anyone to explain the result. I promise it doesn't crash the 3DS (or, I guess I should say, it doesn't crash my SmileBasic 3.3.2 on New 3DS Ver. 11.3.0-36U): it just draws a messed-up line.

  • #4 ✎ 477 SquareFingers Nathaniel: Which one, the very last one I posted? Note that the large range there is over X, not Y. Posted
  • #5 ✎ 168 Nathaniel Avatar Block I didn't change my avatar for 30 days. Website Avatar Embargo I didn't change my avatar for 90 days Website Avatar Taboo I didn't change my avatar for 180 days Website You flipped X and Y when you tried it. Here's what it's suppost to look like: GLINE 0,1E9,1,-1E8 Posted Edited by Nathaniel
  • #6 ✎ 477 SquareFingers Yes, GLINE 1E9,0,-1E9,1 is different from what you did. On my system, it draws a small 45-degree line in the top-left corner of the screen (I think 7,0 to 0,7), and a short vertical line dropping from the lowest pixel (I think 0,7 to 0,14). Two straight line segments, from one GLINE. - I don't mean to ignore, or push aside, your GLINE. I'm just exploring how deep the problem is, trying to give it more context and define it further, so I'm writing about other GLINEs too. Posted Edited by SquareFingers

    Same here. I actually tried it with GTRI, but it just took forever to render a plain white screen.

  • #10 ✎ 477 SquareFingers A clue?: IEEE single-precision floating-point has only about 9 decimal digits of precision. Once that data type can no longer count in '1's, is when this bug appears to manifest. Posted

    Ooh! Try- GLINE 1E9,0,-1E9,64 Looks like this:
    Since the second y value is 64 why does that go off-screen? Weird.

    Interesting bug, it leads to a 3DS system restart, not just SmileBasic closing. -snip-
    That's the normal behavior of a crash on the 3DS.

Website Avatar Embargo I didn't change my avatar for 90 days Website Avatar Taboo I didn't change my avatar for 180 days Website I'm not sure there's any way to crash SmileBASIC in 3.6.0. At least, no way that I've heard of so far. Which might be a good thing... Posted

    I don't think they fixed CONTROLLER, unfortunately.
