Hellu.

Well, I'm working on this level-editor, and I've coded the program so when you're making a small tile, the URL to the object, the object number, its X and Z position are stored in strings in an extern .str file. Kinda like this:

ObjectURL$
Objectnumber$
ObjectpositionX$
ObjectpositionZ$

However, since I'm using the "Write to file"-command, an empty row always exist at the end of the file which is causing my main problem: it reads this empty row as a URL to an object it should load, but can't find it and is therefor returning the messege "Object doesn't exist".
Is there any way to remove this empty row inside the level-editor instead of manually removing by opening the file in notepads?

Thanks!

You write something to the end of the file that isn't going to be used in your main data. Then when you read that back you end reading the rest of the data.

Yes. You should write "END" after you have written everything, and then you should make it read from the file. Before using it, check if it is "END" or not, and if it is not, use the variable in the game for the objects, but if it is, end the loading process.

It's better to just put all that data in an array and use the "save array" and "load array" commands. Which will put the data in the array instantly and you don't have to worry about all those little annoyances (like deleting the file before writing).

Am I the mascot of save/load array or what?

Yes. I didn't know that DB Classic had that command. I thought it was DBPro, but it does.
