Target Systems provides a simple way to prioritize targets using any criteria you can think of.

Each Target System has a particular enemy to scan for within a set of directions and a range allowing for basic targeting but its real strength comes from using the Criteria functionality that allows any script that takes up to 15 arguments and returns a real number to be used to determine which target is the target you want.

Target Systems comes with scripts for the following criteria

  • Closest to Instance
  • Furthest from Instance
  • Fastest
  • Slowest
  • No Criteria

The optional Nth parameter of a Target System allows one to use the same criteria scripts to find the Nth closest instance or the Nth fastest instance. This parameter is usable even with your own custom criteria scripts.

Target System is designed to be similar to GameMaker's own particle systems in set-up , clean-up and ease of use.

Version 1.0.1 now includes a simple line of sight script to help in making of more complex criteria scripts.

Great and flexible

Does everything as advertised and is VERY customizable. Had some initial problems but the author doesn't hesitate with helping you out if you are struggling.

REALLY solid Extension!

For how cheap this was I was surprised by how complete it is! There is a little demo, tons of scripts that can be mixed and matched...But most importantly a really nice PDF that details how to use this system and boy do I apprechiate that!

This review was left for a previous version of this asset.
