But only one gameObject class definition is allowed per translation unit. You actually don't need to define the class a second time just to implement the functions. Implement the functions like this: #include "gameObject.h" gameObject::gameObject(int inx, int iny) { x = inx; y = iny; } int gameObject::add() { return x+y; } etc share|improve this answer answered Sep 19 '10 at 16:29 sellibitze 18.1k24076 1 Ahhhh, thank you! –Dataflashsabot Sep 19 '10 at 16:34 add a comment| up vote 6 down vote the implementation in the cpp file should be in the form gameObject::gameObject() { x = 0; y = 0; } gameObject::gameObject(int

It looks like the header may be included several time. And the whole including cpp files... this is not normally how it is done. –Niall Oct 3 '14 at 13:03 add a comment| 2 Answers 2 active oldest votes up vote 7 down vote accepted You should structure your code between .h (headers) and .cpp files (implementation). You should include header files: .h Never include .cpp files. (Unless you know what you do, and that would be in really rare cases). Otherwise you're ending compiling several times your class, and you get the error your compiler is telling you: 'redefinition of class...' share|improve this answer edited Oct 3 '14 at 13:07 answered Oct 3 '14 at 13:01 Stephane Rolland 14.3k2175119 Why n

I thought that you should make them as well so that the next release http://www.badgers-in-foil.co.uk/projects/as2api/examples/as2lib-0.9/org/as2lib/env/log/repository/LoggerHierarchy.as.html works with MTASC. These changes still compile fine with the Macromedia Flash IDE as well.With this said, I did not check out all of the classes in the XIFF library yet, just the ones that I use at the moment. I will be sure to let definition of you know about the other ones when I get a bit more time to spend doing that sort of thing.I hope things are going well and thanks again for working on this project.-ChrisMTASC compiler errors for the XIFF project: /org/jivesoftware/xiff/im/Roster.as:504: characters 7-19 : type error Local variable redefinition : eventObjvar eventObj:Object = ;Becomes:eventObj = ; /org/jivesoftware/xiff/data/auth/SHA1.as:112: characters 7-8 : type error Unknown variable i /* * Convert a string to a sequence of 16-word blocks, stored as an array. * Append padding bits and the length, as described in definition of class the SHA1 standard. */ private static function str2blks(str:String):Array { var nblk = ((str.length + 8) >> 6) + 1; var blks = new Array(nblk * 16); for (var i = 0; i < nblk * 16; i++) { blks+ = 0; } for (var i = 0; i < str.length; i++) { blks[i >> 2] |= str.charCodeAt(i) << (24 - (i % 4) * 8); } blks[i >> 2] |= 0x80 << (24 - (i % 4) * 8); blks[nblk * 16 - 1] = str.length * 8; return blks; }Becomes:/* * Convert a string to a sequence of 16-word blocks, stored as an array. * Append padding bits and the length, as described in the SHA1 standard. */ private static function str2blks(str:String):Array { var nblk = ((str.length + 8) >> 6) + 1; var blks = new Array(nblk * 16); var i; for (i = 0; i < nblk * 16; i++) { blks+ = 0; } for (i = 0; i < str.length; i++) { blks[i >> 2] |= str.charCodeAt(i) << (24 - (i % 4) * 8); } blks[i >> 2] |= 0x80 << (24 - (i % 4) * 8); blks[nblk * 16 - 1] = str.length * 8; return blks; } 2478Views Tags: none (add) This content has been marked as final.
