I wrote a function to find the total amount of limbs of a given object, but when I run it, it gives me a runtime error, and states that the limb doesn't exist, but the line it points to is the line that checks if the limb exists or not! What's up wit dat?

No good. Actually, I had changed it around quite a few times, and that one happened to be one of them. I did try that one again, just in case, but it didn't work. It might be something wrong in a different function somewhere or something, you think?

Aaaargh! SOMEONE HELP!!! The snippet of code is EXTREMELY important for my project! I have to have this to work! If you have another way to check the number of limbs of a given object, I would LOVE to here it! I looked at the help file concerning limb exist(), and it was no help. I've done everything I could think of! I've even switched the n and x in the parenthesis in case I had those wrong, but it didn't help anything! HELP ME!!! IT'S DRIVING ME CRAZY!!!!

Ho hum... it still doesn't work! Hmmm... has anyone else tried my code? It all looks good, no matter which way I put it (correctly, that is), but it always seems to point at the limb exist() command. The help file regarding that command kinda confuses me, but I think I have it right.
Original code:



Then I changed it little by little. I got rid of the then and added an endif. I set the x=0. I changed the total=total+1 to inc total. I set the limb exist(n,x) equal to a variable and checked if it =1. I added a code to make sure that the object n existed (even though it wouldn't have been called if the object didn't). I even tried to swicth the n and x. Currently, the code is thus:



But each time I run it and it gets called, it states that the object doesn't exist! But I know for a fact that it does because I can see it, and I pass the object number into the function (n)!

The only thing that I can think of is that somehow the object that I'm trying to check doens't have limbs according to DB, but that's crazy! Right? I mean because the object that I'm testing the function with is the alien-mutant.x file. That wouldn't have anything to do with it... would it? PLEASE tell me it wouldn't! That could ruin months of programming!!! I would be scarred for life!!!

Edit: in any case, thanks for your concern: I've been stuck on this all day...

hmmm, object doesnt exist error eh? ok... try this...



and if that ends the program, then your doing something wrong when passing the object number into the function...

I don't think that's it... but I'll try it tomorrow. It's getting late, and my roommates trying to sleep.

Again, thanks for your concern...

YES! The first code snippet was still wrong, but the second one seems to be right! Thank You and incredible lot!!!

Query: why wouldn't my custom made function work though? Strange, no?

Note: I will give you credit for your help! Thanks!

to get your function to work, ill need to see the code that you use to call the function in your main program and then the function code you want to work properly (which doesnt currently work) and ill have a quick look...

Oh, yeah, I guess my last post wasn't very exact...

Here is the current function:



Notice all I did was remstart and end the original code. That's what's so strange about it... that seems like it should work just like the perform checklist thing... oh well...

And yes, the name JessTicular will be added to the credits under "special thanks for help with debugging"
You should be honored! Your name will be the only one other than mine in the credits (excluding my thanks to the makers of DB, of course... maybe a few more... i don't know)

Oh wait! you posted at about the same time I did!

Basically I loaded an object, ( the number happened to be 11) then, I set n=the last loaded object #. If n>10, then it calls the function. Oh, and the error pointed at the "limb exist(n,x) line, and it gave me a "limb does not exist" not an "object doesn't exist" Sorry! I think that was my mistake!

It's odd how no-one else posted in here... usually you get three or four people helping to solve the same problem... Oh well... THEY wont get special praise in your program, so it's their loss... hehe... I'm stoked now...

Great! Testers are always welcome, so long as I don't get to many and I get 10000 e-mails each telling me that they found the same bug... know what I mean?

Alright, I know this post is kinda old, but I'm reviving it, because I still get an error with the command LIMB EXIST(obj#, limb#). It always gives me a runtime error and says that the limb does not exist, but THAT's what I what the program to figure out, IF the limb exists or not! What's wrong with it? It's not a bug is it? (I don't need this for the already posted problem, this is a new one, with the same command doing the same thing...)

Yea, people seem to think that, but I use things all the time w/o the =1 and they all seem to work. But I have tried that before, and it didn't work. Either. Maybe a moderator could shed some light on the situation, hmmm?
