Adding movement patterns to enemies

Now that we've loaded in our pattern data and have a pool for enemies to be spawned from, let's update our Enemy class to work with movement patterns and allow them to be recycled when they move offscreen or get shot.

Adding imports

To start, open the Enemy class and add this import:

import flixel.util.FlxPoint;

The FlxPoint object is an object that contains the x and y values. We'll be using this class to define each point that the enemy will move to.

Adding variables

Next, let's add the new variables we'll need.

private var movementSpeed:Float;
private var movementPattern:Dynamic;
private var movementPoints:Array<FlxPoint>;

Here's the explanation of the code:

• The movementSpeed variable will store the speed value of the pattern. The movementPattern variable will store the pattern data specific to this enemy.

• The movementPoints array will store an array of FlxPoint objects, and we'll convert the array of points from the JSON data to the FlxPoint objects. This...
