HALP! Very basic but strange bug with YSNO & Crash

[mantari]

I have had a crashing problem with a very simple event. I have reduced the code involved to something very small:

Code:

---

FLAG event always

KEYS unstablestar5



STAR 0

NOFL binary1 binary2 blhole

STRN Omni

FLAG nearby

END STAR



CONDITION 0

TYPE explore

STR0 0

END CONDITION

REQ0 0

DISP 1

ACTN popup

GFXP misc/nova.jpg

MUSC misc/nova_loop.ogg

TITL Alien Probe

TEXT Your crew encounters an alien probe of unknown origin which asks you a number of questions related to mathematics and science, but it says it will self-destruct if it does not recieve the answers within 24 hours!<BR><BR>Do you transmit the data?

YSNO 1 2

Try it. Answer "no", it goes to the planet. Answer "yes", it crashes to the desktop. The stderr.txt just says "Fatal signal: Segmentation Fault (SDL Parachute Deployed)".

Remove only the GFXP line and the desktop crash remains.
Remove only the MUSC line and the desktop crash remains.
Remove both lines, and the problem disappears.
Move the GFXP line BEFORE the YSNO line, and it doesn't crash anymore. But the image is placed on top of the text!

I've gone through approx 40 combinations trying to get this to work. I'm at my wit's end. HALP!

Does this problem happen if you give it something more to do on PAGE 2? Like, does it still crash if PAGE 2 also displays some text or a picture?

[mantari]

Good question. Many of my test cases involved mixing in text, when I eventually realized that the presence of text has nothing to do with it.
But I just made the following example (by stealing the Underdelve code from Even Weirder Worlds):

If I answer yes, or I answer no, the result is the same. Crash to desktop.
BTW... this code is generic enough that it can be placed into any mod, if you want to try it out.
I removed all my custom images and OGG files and what not.

Code:

---

FLAG always

KEYS unstablestar5



STAR 0

NOFL binary1 binary2 blhole

STRN Omni

FLAG nearby

END STAR



CONDITION 0

TYPE explore

STR0 0

END CONDITION

NOTE: It also seems a bit unstable. From the code, above, I just removed the NOVA statement from page 1.

So then, it worked when I said 'YES'. [new game] Then it worked when I said 'NO'. [new game] 'YES' worked again. [new game] 'NO' crashed to the desktop.

UPDATE: I did a new game (again, with the change of the NOVA statement removed from page 1). Yes and no worked several times, no problems.
I thought I was going crazy.

So I quit Weird Worlds and started the program again.
I went to the star and said 'NO'. Crash to desktop.

I have had nothing but problems when trying to do anything substantial in a YSNO or GOTO page. I try not to use them except to display text. It's sad too, because I wanted to make some Away Mission quests, but because you can't do YSNO in a planet exploration window, they break the mood to begin with, and then when most commands fail to work reliably, that was the death knell.

[mantari]

Ditto on also having problems with GOTO on working with anything but multi-page text.

Hey Fingers, your thoughts?

[sgqwonkian]

I've recently been working on a couple of medium-deep quests with YSNO and GOTOs and have had no troubles (beyond the TIME bug and bug with using a single code more than once in a page mentioned elsewhere).

I'm curious where you're putting the other commands in the GOTO pages...

I've been doing
DISP
ACTN
GFXP
TITL
TEXT
MUSC
other misc commands
GOTO
END PAGE
in that order without a hitch. Is that the order you've been using?

[sgqwonkian]

Sure, I had to brag.
Like an hour after that post I started hitting major bug-snags.

The ones using the codes listed there are still functioning fine,
but some others are wrecking my brain.
