Solo Pong is now pretty much ready for exhibition at Open Studios! For this week’s assignment I added a boss stage, where I used object arrays and array lists to manage the boss’s attacks and a couple of particle systems. 😀
So I based the code for the boss enemy directly from what I had written for the block collision detection. I just made the boss a huge block with movement and more life points.
The interesting part (and the one that has to do with the actual assignment) was coding the projectiles and particles.
For the boss’s projectiles, I created a class very similar to my Ball class. Using an array of objects, I created several instances of the class BadBall and “called” them to the screen to be shot using a function and iterating one by one through the array. That way, there was no need to keep creating BadBalls or calling them individually.
For the particle systems, I used array lists. I created a piece of code that would use a for() loop to generate a fixed number of particles. Each particle would have a set time to be alive, and at the end of it the program would call the remove() function to destroy the object. Hence, the particle system could be created (splattering little red blocks everywhere) and then every element would die and be removed one by one, stopping the program from slowing down.
Additionally, as I mentioned in my previous post, I also used an array list to take care of the box count in the block breaker stage: by using the function ArrayList.size() I could monitor the amount of blocks left and advance the game once there were none left.
So yay! Revised code is down here:
