Preventing "entity does not exist" type of errors?  

Hi! I'm glad to finally become a member of this site. :)

I've been having a lot of fun programming on this amazingly compact and versatile IDE, but one thing I cannot wrap my head around is a common error i keep running into that confuses me a lot.

There is no specific code that this applies to, it just happens to me every now and then and I get stuck, often with functions and external *.bb files.

Basically I'll declare a variable within a function, and referring it from elsewhere will give the "-does not exist" error. Are there any 'guidelines' that can help prevent errors like this?

Thanks!

Hello and welcome aboard. Blitz3D Entities always return a non zero integer when created so you can do some conditional checks before doing commands associated with the entity in question.

Thank you!

Btw what do you mean by conditional checks?
