http://www.knoxgamedesign.org/2105/curves-knox-game-design-july-2022/ Overview of four types of curves that can be used in game development. Basic parabola for moving objects in an arc. Sine function for moving objects in a wave motion. Physics using velocity and acceleration for simulating actions such as jumping and falling. Bezier curve for moving objects along a curved path. Examples of functions for each curve type and how to calculate coordinates in a spreadsheet. Demonstration of how to implement each curve type in Monogame with C# and review of source code. Correction - Acceleration units is meters per seconds squared m/(s^2)

This month's Knox Game Design presentation topic is Enemy Behaviors. This is a look at various enemy behavior types: - Back and forth (timer / collision based) - Alert and chase, using distance / timer for stop chasing - Move random direction and wait - Orbital children, with varying radius length and orbit speed - Behavior combination (orbital children and move) This presentation looks at a demo project using Monogame and C# and analysis of demo code for each behavior. http://www.knoxgamedesign.org/2086/enemy-behaviors-knox-game-design-may-2022/

Play online - https://levidsmith.com/games/waiter-extraordinaire/ Help Chester Servesalot deliver drink glasses to all of the customers at the tables. He is an expert at balancing glasses on his serving tray, but his greatest fear is mice. Bumping into a mouse will cause him to lose balance and drop all glasses on his tray. At any time, he can return to the orange glass table on the left side of the room to refill his tray with glasses.
