Create an object with a ' or " character in its name, then place the object on a map file, and compile. DM will produce errors when attempting to read the mapfile, and cannot subsequently load it.
Numbered Steps to Reproduce Problem:
1. Copy and paste code provided into Dream Maker
2. Create a new map
3. Place a 'test"object"' on the map
5. Make a new map.
6. Create a new 'test2object' instance
7. Edit its 'test"' variable
8. Place it on the map
Code Snippet (if applicable) to Reproduce Problem:
Either ' and " characters should not be allowed in identifiers, or they should be escaped in some way in the map file, allowing the parser to read it.
Quote marks are allowed in object names and variable names, and come out unscathed in the map file.
Does the problem occur:
Every time? Or how often? Variables are fine as long as they're not changed by any instances. Other than that, every time.
Did the problem NOT occur in any earlier versions? If so, what was the last version that worked? (Visit http://www.byond.com/download/build to download old versions for testing.)
It likely works in all versions of the Dream Maker IDE that supported maps.
Don't use ' and " characters in identifiers.
Haven't checked, but similar problems might exist for the import/export text format for savefiles. Will likely test that soon.
