ya CRO means Cathode Ray Oscilloscope
I want to get some tutorial how to make games using CRO
see this
Master's Level(The Frogger Game):
Problem Statement:
Design an electronic circuit which implements a simplified Frogger game on a Cathode Ray Oscilloscope (CRO). The game consists of a series of roads on which vehicles move and a human player helps a frog move to the other side of the road using his control keypad.
Eligibility and Team Size:
Any student enrolled in an undergraduate/postgraduate at their institute is eligible for the competition.
Members per team should not exceed three.
Basic Problem Description:
1. The game consists of five horizontal lines, which represent four parallel roads.
2. On each of the roads, moves a single ball which represents a vehicle.
3. Each vehicle moves on the road with a speed different from other vehicles.
4. The semicircular cursor represents the frog which can be moved up, down, left or right using the four buttons.
5. On the press of the up/down button the frog moves up/down the road.
6. On the press of the left/right button the frog moves left/right on the road.
7. When the frog has moved up to cross all the roads, the level is completed.
8. When a level has been completed, the next level starts with an increased speed of the vehicles.
Optional Additional Features:
1. The direction of motion of a particular vehicle could be either leftward or rightward (decided “randomly”) but fixed for a particular level of the game.
2. A time-over constraint, if the level is not completed with a specified amount of time.
3. Two vehicles on a single road. (For this case implementation, you can make any other road devoid of a vehicle)
4. Introduce sound effects.
Rules:
1. Microcontrollers/microprocessors are not allowed for the implementation of the problem.
