strange animation bug

[8pack]

Hello everybody,

i am working for years on a larger topdown project. Now a bug has occured, that gets me busy for weeks.
the following happened during an larger game animation and while trying to reproduce the bug with a new object, the bug is still there against all logic.

I created a new object and within this object default animations 12 and 13. Each animation is filled with a block of 300x80 pixel size, the animation is looped and then all 32 directions are filled with "create rotated animation".

Then there are just two event lines for this object:
when hit "space" then set direction of object to one of 32 an play animation 12
and
when hit "enter" then set direction of object to one of 32 an play animation 13

Now the bug:
Most of the time the object just disappears, when the button is pressed.
Some of the directions are shown completely, in some directions only some frames are shown, while some frames stay invisible.

If a change the pictures in the frame editor in anyway, lets say i change the color or resize the boxes a little, the bug changes everytime. Now other directions are shown, while others disappear.

My application is quite large. I contains about 11000 events and severel hundred groups. The application was created in mmf 1.5 back in the days, if this is importend. And i currently work with the mmf2 developer demo (build 253), because my original disc was destroyed in a fire
i dont use hwa.

However ive done a lot of testwork the last weeks:
the object doesnt get destroyed, it is still there and reacts to collisions. Despite being invisible at some frames or complete animations, the object is counted as "visible".
It can still use values and everything, the debugger isnt a help either.
If I create the same object with the same events in another frame within the same apllication, everything works fine.

Of course, i have partly reduced / deleted my code, to make sure, the other code isnt responsible for that. Even when I deactivate ALL groups, what means NO code ist active, despite the 2 events mentioned above, the bug is still there. Only, when I delete about 3 / 4 of the whole code, the bug disappers, what isnt logical, because in my last backupcopy i had the same amount of events and groups, and the bug wasnt there.

My guess is, I am hitting some kind of limits of mmf2, although a dont know, which one.

ps: i have played around with application and frame properties of course. Things like "load on call" and such seem to work sometimes, then again it doesnt work.

I hope, this is all understandable!!

Thanks for your time!!

Oh and of course, i dont have to many objects. i have about 200 on screen at the same time, my limit is set at 10000.

Does it matter what 3/4ths of the code you delete?

First save the Application under a different name, so that you dont mess up the original Project in any way.

1
- Delete 1 Group at a time from the Event Editor
- Run the Application inbetween each deletion, and see if the Bug persists
- Do this untill you find the 'Problematic Group' responsible for the bug

2
- Delete 1 Event at a time from the 'Problematic group'
- Run the Application inbetween each deletion, and see if the Bug persists
- Do this untill you find the 'Problematic Event' responsible for the bug

3
- Report back here and post all information about the 'Problematic Event', all Conditions, all Actions

Its time consuming, but it gets the job done

Sometimes MMF2 bugs happen even when they logically SHOULDN'T happen.

It's a great great program but when that stuff occurs it's aggravating because you can't fix it though means that would normally make sense.

it doesnt seem to matter.
Ive already tried, what you said. with deleting one specific event i thought i had found the reason. Then i reloaded the file and deleted exactly the same events and the bug still was in there, until i had deleted the next 10 groups of events. just doesnt makes sense.

by the way, IS there a limit zu groups, events and such?

thanks for the respond!!

Compared to trying to debug pure programming code, it's a cake walk. I find it more frustrating when an entire project crashed due to missing one semi colon or closing bracket.

Does it matter at all which Groups you delete, or can you delete any 10 Groups at random to fix/ remove the bug?

i doesnt really matter. I can begin to delete from the top of the coding and suddenly the bug is away. if i begin at the bottom, the bug is sometimes also away, but not at the same point as before. if i try to do the same again, the bug goes away at another point.

again: i have also deactivated ALL groups, except the two events for my test object, and the bug is still there........

also, my last backup copy is just several hours older and the changes i did between are just within one group an not really complicated. In this backup copy everything works fine. tomorrow i will just take the backup and do the changes again and see, if i run into the same problem again.

Aha, so its inconsistent like that.
Strange thing, ive never heard anything like it.
It seems that the only clear pattern to see is that 'reducing the number of Events OR Group Of Events removes the problem'.

Good thing is your backup is only hours away, backups are allways nice.
If you are able to continue from your backup, without the issue resurfacing, that would be best in my oppinion.
Maybe this is just like a rare freaky incident ( which corrupted your .mfa in some way ) which probably wont happen again.

There is allways the posibility that there are limitations to the number of Events or Group Of Events.
I remember there was a thread which discussed and listed the various limitations in MMF2, like Event limits, Object limits and such.
However im not able to find it, maybe it was in the old forum or in a different forum.
