    Step 3: Creating the Enemies<\/h3>\n

    Well, now that we can make our lil’ guy shoot, we have to make something for him to shoot at! I’m going to first start by just drawing a little enemy guy. It won’t be too artistic.
    \n\"My
    \nIts dimensions are 30×30 if you wanted to know.<\/p>\n

    Now, do the same thing we did for the bullet, convert it to a MovieClip, and Export it for ActionScript.<\/p>\n

    Next, we’ll do something similar to what we did with the bullet. We’re going to add two timing variables again at the top of the code:<\/p>\n

    \r\n\/\/ENEMY TIMING VARIABLES\r\n\/\/how much time before another enemy is made\r\nvar enemyTime:Number = 0;\r\n\/\/how much time needed to make an enemy\r\n\/\/it should be more than the shooting rate\r\n\/\/or else killing all of the enemies would\r\n\/\/be impossible :O\r\nvar enemyLimit:Number = 16;\r\n<\/pre>\n
    Now, in order to add this enemy to the stage, we have to program this into the onEnterFrame<\/tt> function:<\/p>\n
    \r\n\tenemyTime ++;\/\/incrementing time for enemy\r\n\tif(enemyTime == enemyLimit){\/\/if enough time has elapsed\r\n\t\tvar enID:Number = Math.random(); \/\/create a variable that we'll use at the enemy's id\r\n\t\t_root.attachMovie('mcEnemy', 'en'+enID,_root.getNextHighestDepth());\/\/then add the enemy\r\n\t\t\/\/setting it's coordinates\r\n\t\t_root['en'+enID]._x = int(Math.random()*Stage.width);\/\/randomly within the boundaries\r\n\t\t_root['en'+enID]._y = -50; \/\/sets this offstage at first\r\n\t\t_root['en'+enID].onEnterFrame = function(){\/\/then give it some functions\r\n\t\t\tthis._y += 5;\r\n\t\t}\r\n\t\tenemyTime = 0;\/\/reset the time\r\n\t}\r\n<\/pre>\n
    This concludes this part of the tutorial. Next time, we’ll program the enemies so they get shot!<\/p>\n
