Openbor crashes without log

Toranks · Feb 8, 2020

There is an error that does not happen with the Build 4153 but yes with the latest release 6391 and the 4.0 alpha.
It's rare, but it's annoying because of randomness, besides leaving no trace in the log (only a Windows 7 "APPCRASH").

I have identified the origin, it is a script that is activated when an enemy grabs you, and that allows you to free yourself from it by mashing buttons.
The error occurs when many enemies try to grab you simultaneously or successively, but it doesn't happen always.

How can I identify the exact origin of the error? Is there any way to activate extra debug logs on Openbor?

(I don't know if this is the right section, sorry)

post your script so people could change your script into different script that would work better.
No info crash ( no shutdown and no log trace) happens also when animation frame is missing, i woyld prefere if engine would use frame none and output to log missing frame, why ? Cause i spent 3 hours looking everywhere else, i deleted frame by accident, it was a frame in type none entity, i used it for bg decoration.

It's not mine, so perhaps the problem may be in another function that is activated here and I does not know it.
I have reviewed the frames and none is missing, it is also a very rare error, if frame absence were the cause it would occur always a certain animation is activated.

bWWd, if you can type up something very specific describing what happens I might be able to add some enhanced logging.

There's no really viable way to log missing frames, because frames as you think of them don't actually exist. In OpenBOR, an entity has an array of animations. Logically you'd think each animation has an array of frames, and it would look like this:

entity->animation[animation_number]->frames[frame_number]-><some frame property>

...but it doesn't work that way at all. Instead, animation properties that need to work on frame basis (like the sprite image), are each their own array. So it actually looks like this:

entity->animation[animation_number]-><some property>[frame_number]

Sounds crazy at first, but it saves an unbelievable amount of memory. The point is, there's really no such thing as a frame, so there's really nothing there we can debug. But if I know your situation, I might be able to write something that can catch the problem a different way and log it.

For these crashes I use the normal debug mode, which shows you the invisible entities, so I can identify which one and when it crash

Bloodbane · Feb 9, 2020

Toranks, I noticed something in grab1.txt you quoted above. It starts as an obstacle, however it changed type into NPC. This could be the source of the problem cause obstacles don't need certain animations such as PAIN while NPCs do need those

grab1.txt doesn't have PAIN and also doesn't have anything to prevent it from playing PAIN

That's my thought on the cause of crash without log for now, i.e missing PAIN animation

Toranks · Feb 10, 2020

Thank you, I will try that. That error has not happened to me again, it only happened to me twice. If with the pain animation works well, I will leave it that way just in case.

I think its not worth to add additional checks just to catch missing frames after eveyrthing was already loaded, i removed some unused stuff and some important stuff was also deleted, so i kept having shutdowns with no log info about missing frame, i brought back folder with frames and it was all ok again.
The issue is searching for the cause , crash and no info is a bit nasty problem to have unless you remember what you did between game working and game not working.

Anyway, i will derail a bit and ask is there any way to have multiple obstacles to create mario like levels ? Or something to create stage from blocks kinda like tiles that could block characters movement and not drain so much memory to slow the game down ? After awhile game starts to slowdown on android devices with so many obstacle entities, like labirynth stage for he-man.Heres text file for stage and obstacle entity:

As You see, entity is not complicated but it does drain resources, it would be nice to be able to have those simple one frame /tile like entities without consuming so much cpu cycles.
OR maybe there is completely different way to create this kind of labirynth level with walls that can block you from passing through them.

I think I found a possible cause! What bWWd told gave me an idea to look for
All fall7 animations on all characters are linked to a script grab system, and this related to the escape script. In all the main characters the fall animation look like this:

Code:

anim	fall7
	delay	1000
	offset	45 95
	bbox	0 0 0 0
	frame	data/chars/1ryo/slam0.gif

	frame	data/chars/1ryo/slam1.gif
	offset	50 85
	frame	data/chars/1ryo/slam2.gif
