I'd like to know what is the limit of IsID (if it exists) SC supports. This is something I never tried to look at, due to the limitations of other aspects of Starcraft like the number of images, sounds and other features of the game. I always believed that the IsID limit was absolute, but it's not.

Also, I noticed that there are many IsID unused in the normal 412 IsIDs from the Iscript.bin file, like the #1....

It'll be convenient to know if that is because that IsID group are defective, or some other reason.....

Thank you for reading.

As far as I know, the file size is the only real limit.
2-byte offset locations can only mean 65535 bytes of data.
Of course it can be extended just slightly, but that extension isn't significant.

Iscript IDs themselves are not an index. Iscript.bin has a table full of numbers paired with pointers, the numbers are the iscript IDs. You can just throw in any arbitrary numbers you'd like as an IsID as long as it is unique.

That's something nice to know, thank you.


Oh, of course, the 64kB file size.....Thanks a lot!
