You deleted your flash. Why? Even though you stole the content, it was still something you created.
With that being said, you're too late. I have already seen the flash in question, and no doubt, you stole my beam effect. Am i mad? No, instead i pity you. I pity the fact that you had to steal something someone else created in order to achieve some sort of mediocre success.
It really makes us sprite animators hypocrites, due to the fact that we take sprites that other companies create, however, that is where it ends. As sprite animators, we have the option to take these sprites and make them do phenomenal things that people haven't seen before. You de-compiled a flash, and apparently you plan on deleting all of your work because you got busted. You're admitting to the fact that everything you made was stolen.
Effects and sprites are hard to account for being stolen. Many people make customs of sprites and what not, and really, sprites are easy to edit. However, you stole a hand made flash graphic from me, using a de-compiler. The only way you could have gotten that graphic is to get the .fla or seen a .swf that had it or i personally have given it to you, which 2 of those seem VERY unlikely. Besides, i made that blast 2 years ago.
If you like an effect that much, then ask for it. Not just from me, but from everyone who has it. I, and many others, put credits to where we get it. It isnt hard to do some searching. If you cant find it, email the person and ask them. I have asked for things i couldn't find from other sprite authors, and they have done the same from me out of respect.
My advice to you is to just start over. Don't delete your flash, but re-name it to 'Mistake' let it be there so as a reminder to yourself that you don't ever have to revert to stealing content to get success, and when you do achieve something then delete it. Make something that is UNIQUE. Because no offense, everybody and their mom is making some sort of SMBZ and even Alvin doesn't like it. You can paint an Orange red and it will still be an Orange.
