Now, let's make the function that will spawn in enemies and give them their pattern data. After the constructor, add this function:
private function spawnEnemies(timer:FlxTimer = null):Void{}This function will be called as a timer callback and in the constructor, so it takes in a FlxTimer object that defaults to null.
Inside the function, add the following line:
currentPattern = (Math.floor(Math.random() * ((patternData.patterns.length-1) - 0 + 1)) + 0);
To start, we'll decide a random pattern to be used. We do this in the same way that we've made random ranges before. The one difference here is that we're using patternData.patterns.length to determine the maximum value. This means that we're checking the length of the patterns array from the JSON data.
Just to nail home the point, we can now use the JSON data like we would with any other object. The patterns array from JSON gets converted to an array of Haxe dynamic objects. The Json.parse function will intelligently convert...
