This little game was made in the custom game-engine that we got from school.

This was how it looked, rather simple but that was what pong was anyway.
This game was one of the first games of mine that included audio. There was background music (which was The world revolving, from Jevil from DeltaRune), a hit sounds if the ball hit a paddle and a sound when the ball hit a side.
Also when the ball hit a side, the opposite player would get a point (obviously) and a purple splash would appear where the ball hit the side.
The project in code was quite a mess since it was all written in one script but I will try to show some parts of the script.

This was used to 'paint' the game. It draws the players, the ball, the score, etc.
It worked which was the most important part, but it definitly was annoying to guess where things were supposed to be, because you couldnt really see positions unless u'd start the game, so it took really long to start the game, check coordinates, close the game, change the coordinates, start the game, etc.
This was a huge problem with all the custom engines though so I wont mention it again (probably).

This part shows that when the ball hits a side it will play a sound and speed up while also changing directions.
This was a fun little project, just wish it was done in Unity instead.
