You don’t have to beg Knicks forward Doug McDermott to be more aggressive offensively.

His coaches have delivered the message, and McBuckets is ready to answer the call.

“Definitely I got to be more aggressive. That’s on me,” he said Tuesday night at the 19th Annual Knicks Bowl charity event. “The coaches harp on [it] all the time. Sometimes I’m a little too unselfish, and there’s times where I need to be selfish and try and score more.”

Through the first 40 games of the season, the 26-year-old is averaging 8.3 points on 46 percent from the field and 40 percent from beyond the 3-point arc in 24 minutes. His shooting has been key off the bench.

But with second-leading scorer Tim Hardaway Jr. still sidelined, even McDermott admits he can do more to pick up the slack.

“You don’t have to tell me to shoot more twice, so I’m definitely going to be more aggressive,” he told The Post.

Those shots have fallen with less consistency of late, as McDermott is converting just 38 percent of his attempts in the last eight games. Opponents are starting to hone in on his tendency to move without the ball and position himself for open kick-outs.

“I started off the year so great,” he said. “I think teams are starting to game plan [for me] a little more — taking away my outside shot. I need to find ways to be more effective out there.”

His recent struggles should not deter him. Simply by looking to score more, McDermott puts pressure on the defense. In games in which he has taken eight or more shots, the Knicks have gone 11-6.

And his shots will eventually go down. The Creighton product certainly hasn’t lost confidence, as he buried a buzzer-beating 3 to send a game against the Heat into overtime on Friday.

“I just want to win and I think it’s all going to start clicking,” he said.

McDermott’s first chance to demonstrate his more assertive approach will come Wednesday when the Knicks play host to his former team, the Bulls.

“It’s one of those games we really need,” he said. “It’s a big home game after a good win in Dallas. Definitely one I’m looking forward to.”
