Aim a shot. Feel the difference.

Maths for Games now offers two independent starting points: the five Dice Roller probability lessons and six lessons on aiming and movement. Place a point, measure a triangle, explore trigonometry and radians, then aim at a target and see how fixed-point precision changes the shot.

The Game Feel movement playground gives three ships the same input. Compare immediate response, sliding and slower acceleration, then inspect the rules behind the difference. Four Game Feel lessons now take those rules apart, starting with how a ship responds to input.

The Craft also sets out seven module homes, distinguishing available material from planned coverage in design, AI, data and algorithms, graphics and audio.

Two Spectrum BASIC lessons also gain editable browser playgrounds: Make the Spectrum answer and Read the sonar. Edit and run the program directly, or download your changed source as a tape.
