Description
For the midterm assignment, we were asked to make a video game using processing. I made one in which the person has to try crossing the road without getting hit by the car.
Process
I used basic shapes to create a scenario of a road on the screen. The roads are made out of the rectangles. The cars are made using the rectangle with curved edges and ellipses for wheels. Along with a sun in the corner.
So my game is quite simple. Using sprite sheet, I made a person move across the screen for the game. The cars come from the side in random speeds to try and hit the person. The speed increases with increase in every level.
There are three levels in total and are shown in the top-left corner. When the bar goes all the way up to green, it means that the player has all three lives. On getting hit by the car, a life is reduced and the player as to start the game all the way from the start of the road.
I have added sound to the game( which somehow does not come in the video below). The sounds add a a special affect to the game I believe. The start of the game shows instructions on how to play the game. Just follow the simple instructions and win the game.
The player to cross all three rounds, wins the game. Here’s the video for the game:
