Game Description:
When the micro:bit “A” button is pressed, the game starts. The user’s LED will appear at the bottom center of the screen(2,4), and the egg’s LED will appear at the top center(2,0). The egg falls at a rate of 1 second. The user must tilt the micro:bit left or right to move their character to catch the egg. When the egg is caught, the score increases by 1 and the egg will reappear at a random position at the top. Every 5 eggs caught, the game speed increases by 0.5 seconds;
If the egg falls to the bottom and the user does not catch it, the game ends.
Simulation Diagram:
Step One:
When the program starts, initialize and set the initial values of“range”, “start-X”, “U-targetX”, “speed”, “start” five variables.
Step Two:
If“Start” is not greater than 0 (less than or equal to 0), LED displays“press A”.
Step Three:
When the“A” button is pressed, create“U”and “egg” characters at(2,4)and(2,0), change the variable “Start” to 1 and store the X value from the accelerometer into the variable “start-X” (as a baseline for judging tilt).
Step Four:
• If“Start” is greater than 0, set variable “U-targetX” to “x direction acceleration value minus variable“start-X” divided by range plus 2” and move the character “U” to the LED position specified by variable “U-targetX”, pause for the seconds stored in variable “speed”(1 second), then move the character“egg” down 1 space;
• If“egg” reaches the bottom(y=4) and“egg” and “U” do not touch, the game ends;
• If the above conditions are not met, and“egg” and “U” touch, gain 1 point, and move “egg” to a random position at the top(y=0), pause for the seconds stored in variable “speed” (1 second).
• If none of the above conditions are met, and the score is a multiple of 5 (0 does not count), increase the game speed by 0.05 seconds and store it in variable“speed”.
