Target Closest Enemy MovieClip

I’ve been thinking about how targeting the closest enemy would work and started experimenting with the algorithm. Basically AS has an array method called sortOn, that sorts objects properties in any order you want. Well, that’s the catch. It only sorts objects, not movieClips.

The work around is simple enough; when creating a new enemy object, just save a reference to the movieClip on stage inside the object’s property.

Simple Enemy Random Movement

Here is a simple AS2 enemy creation/ai script that allows you to create enemies that move about randomly inside a container movieclip. You can set custom movement boundaries/borders. When an enemy hits the border, it will “bounce off” and move in the opposite direction.
