4 A Lunar Lander game is to be developed with following specifications:
User input - It take input from pilot as increase/decrease speed which is directly mapped to required burn rate.
Other inputs: Lunar Lander has two sensors:
(i) current burnt rate
(ii) current altitude
Output: Based on these 3 inputs determine new burn rate and set different parameters like altitude, velocity and display them.
Draw an architecture using any of the two styles:
(a) Object oriented style
(b) Rule Based style
(c) Black board style
