I'm currently developing an 2D SFML Air Hockey Game, and I've got my graphics menu, score,collision detection, and sound effects in my game. The only thing that remains is collision resolution . I'm not sure how to start, and I've had no experience with Trigonometry(12 years old . Im trying to get the mallet, to hit the puck, so the puck can glide across the board based on how hard the player hits it. Can someone help me?
