I made a program that re-creates the classic game called Space Invaders You can read more about it here: https://en.wikipedia.org/wiki/Space_Invaders This is not plagiarism! I did not copy this from anyone, and I coded this entirely myself. If you do not think that I am telling the truth, look at the code for the other Space Invaders games, and you will see that I didn't copy them. NOTES I changed a few things from the original game. 1.The enemies move and shoot their lasers slightly faster. 2.The player itself can fire multiple lasers at a time, instead of waiting until your previous one hits something. This, however, cuts both ways. If the alien invasion is too close or you need to cut a hole in your base, it is actually faster to get your laser back the second it hits. 3.In the original Space Invaders, you used the Space key and the arrow keys to move your laser cannon around. To make it easier to play, the Space key has been substituted with the up arrow key. Also, this game will lag a bit once you start it (as it is "get"ing the background), but it will be super fast once it finishes. / /IMPORTANT VARIABLES/ var alienDirection = "RIGHT";//Which way the aliens are moving var moveDown = false;//If the aliens are moving down var score = 0;//How many points you have var lives = 2;//How many lives you have var state = "menu";//Which screen you are on var highScorePage = 0; var clickBuffer = 0; //The highscores var highscores = [ ["2610","Mehal Narwal"], ["2540","AlexT"], ["2030","Matt"], ["1770","SkyTDM"], ["1280","TheMunchingCow"], ["1040","22willharvey"], ["800","Tegoon"], ["800","blue3456"], ["670","Amae3443"], ["570","Camon Lowry"], ["570","Hasan Maharoof"], ["370","Ryan Wittmers"], ["?","Person"], ["?","Person"], ["?","Person"], ["?","Person"], ]; //An array which contains all of the different keys you can press var keysPressed = []; //Tells the array if the key at <keyCode> position is being pressed.
