Scott said Didak, who failed to cope when Hawthorn's Ben McGlynn annoyed him all night as the Magpies lost to the Hawks four weeks ago, was brilliant in his refusal to let King irritate him into submission.
The heated match-up lasted the whole game, and sparked an all-in melee in the second quarter when King struck Didak behind play.
Scott said the Magpies were delighted with Didak's ability to block out the distraction, pick up 23 touches and kick two goals.
"Everyone highlighted the fact that McGlynn got under his skin against Hawthorn, and we knew Richmond would try and do the same to him again today," Scott said after the match.
"He responded brilliantly. We were rapt with his efforts both offensively and defensively, and to hold his nerve under pressure.
"With work the coaches, particularly Mick [Malthouse], have put into him, we were expecting he'd respond like he did today.
"Today he was completely in control of every situation. Players tried to get under his skin, it didn't affect him, and the game was played on his terms and our terms."
Scott said the Magpies were pleased with a four-quarter effort that saw the players build a massive first-half lead and hold onto it.
"We put certain things in place and the boys followed the game plan to the letter, really, probably apart from the last 15 minutes where subconsciously, it's difficult to keep the pressure up when you're that far in front," he said.
"We were very pleased with the boys' effort.
He also said boosting the side's percentage was very important, and had been a focus of Collingwood for the past few weeks given the hot battle for a top four finish.
"I think it's shown throughout history that sides with percentages 120 and above are genuine premiership contenders," he said.
"We're closer to that now, and that's been a goal of ours."
Scott took over the post-match press conference duties as senior coach Mick Malthouse left directly after the game to visit his ill mother in Ballarat.
