¶1Antwan Grooms appeals his convictions of obstruction of an officer, battery, and giving a false name to a law enforcement officer. He challenges the sufficiency of the evidence. Finding the challenge wholly without merit, we affirm.
¶2At the time of the incident, City of Stone Mountain police officer Mark Addington was working as a uniformed, off-duty police officer providing security at an adult entertainment club in DeKalb County. Grooms was a club patron. Alan Miles was a club bouncer. When *767Addington became aware of Grooms’s presence, he asked him to leave because Grooms had been banned from the premises. Addington and Miles testified that shortly thereafter, Grooms punched Addington in the face without warning or provocation. Addington and Miles then attempted to subdue Grooms. They did so with the aid of a City of Clarkston police officer who came to the club in response to Adding-ton’s radio call for emergency assistance. DeKalb County police officer Calvin Carter also came to the scene and arrested Grooms. Carter testified that, at the time, Grooms was extremely inebriated and belligerent. Carter also testified that Grooms gave him a false name. In his defense, Grooms testified to the effect that Addington and the bouncer were the aggressors in the affray, that he had done nothing wrong, and that he had acted in lawful self-defense.
¶3Resolving conflicts in the testimony of witnesses and weighing the evidence are functions for the jury.
¶4Judgment affirmed.
