Hi all,

Been a while! But I've come across a weird phenomenon. My game is hitting a bug inside of a function that can't possibly have run yet... I can't put the actual code because there's far too much of it, but think of it like this:



See how the function isn't even being called? The error I'm getting is "Effect does not exist" so it's not a syntax error causing it. It only happens during runtime... Anyone ever had this happen?

Probably it's just that the line number of the error message is wrong.

@basjak - No, no, I explained in the post. That's not the actual code. The actual code is too long. The code I put there is to help explain what's going on.

@Diggsey - You're probably right there...

If you are using modular programming, best to enable error trapping, found in the STYX plugin...

EDIT

Linked STYX for future readers

if this your code, and you hading this error when you closing the engine, then you should know that dbp runs all the commands that after your loop when it exists. even if its a function
the way you can fix this is simple put END command on the next line after the LOOP command.

Yes, I always put an end statement there just in case I exit the loop for some reason. Seems possible that's what's happening here.

It sounds more like a resource handling problem. If the error message is "effect does not exist"
and is occurring at runtime I would put some error checking where you use all your effects.
Resource handling in a game engine is one of the most important basic requirements.
I believe I had this problem once when experimenting with "Advanced Lighting". It turned out
to be a error with Evolved's find free resource functions. I use Matrix1's commands instead for
resource management.
This is the most common error people make in DBpro. You must consider resource
management especially if you want to avoid the "Device Lost" scenario which is not a bug in
DBpro as so many claim. Also DBpro does not run functions after exiting the main game loop.

If you're having a runtime error then the program is still inside the loop.
It is not logical to think that calling "end" after the loop would solve a runtime error.
Dbpro does not go in and out of the loop during runtime. You most likely still have a resource issue.

It's not. It's a compiler error. It's been confirmed.

I had similar problem before when I ran a very long code. two functions, first sound function, second dialog box function. they worked when I took those functions and put them in very short program. but conflicted when back to the program.

however. they worked I created a new file and put them in it.

don't ask me why but try different options.
