if you are charged with aa/dw 2nd. for shooting someone, if the person that was shot doesnt show up in court to testify, can you still be found guilty

Yes, the State can still get a conviction, if they can prove the elements of the offense without the person who was shot. Generally, they'll bring in the cops who wrote the offense report(s), and any other witnesses who saw what happened, as you have noted. There may also be additional evidence that can be used to get a conviction. Your best bet is to hire a lawyer to fight the case; not to hope the complainant fails to show up.
