Error during simulation.

[Amy]

Right now, I am working on a project for my programming class. We have to use events with functions to make somehting happen, if something else is true. Everything was going fine, but then when my dog gets near the bird, the error comes up. Here is the error:

Error during simulation.

right now, it is programmed to do this:

If the dog gets within 1 meter of the bird, the dog will jump up and the bird will move upward, then they each return to their original positions. If I take everythign out of the method that is called, and just leave in "dog say hi," then it works.

Hope you understand what I mean. if you need me to post my code or something, I can, just let me know.

Thanks!

It would be great if you could post a copy of your world for us to take a look at. Then we can determine if it's a bug with the software or with your code.

Hi,

i just created an simple alice world with controls to move a bikerkid object with the a chase cam feature.

However, when i start to run the simulation and hold down "w" for a few seconds to move the the bikerkid forward and release "w" key, an error occurs saying "Error during simulation". (some ArrayIndexOutOfBoundsException)

Error message as follow:

Error during simulation.

Need help badly pls ... any help will be much appreciated
Thanx in advance

[AliceNoob]

Btw the above error doesn't occur when i remove Biker Movement Method.

Biker Movement Method basically makes the biker legs paddle the bike when he moves (using a do together tag)

attached is the code

[ronnan713]

Yeah, I have been having the same issues and seems like there isn't a workaround, I have have spent alot of time and tried everything, starting to believe it's a BUG! I am not creating hardly any code in the attatched program, using objects with already created methods.:mad:
Error during simulation.

[x2495iiii]

It is a bug, but there's also a workaround.

I went ahead and fixed it for you.
