However, beneath the surface of this apparent chaos lies a rigid, highly predictable set of rules governing Artificial Intelligence.
This article will dissect the mathematics of sightlines, retargeting, and unit hitboxes to help you manipulate the AI flawlessly.
The Concept of Sight Range
Every single unit in the game possesses a hidden 'sight range' value, usually measured in invisible tiles.
As long as you place a building just barely inside the tank's sight range, the tank will alter its path and walk toward your building.

- Count the squares to ensure perfect placement.
- Resetting aggro saves games.
- Adjust your placements for air threats.
Advanced Aggro Tricks
Large tanks have massive hitboxes, meaning melee defenders can attack them from slightly further away than smaller troops.
This highly advanced technique, known as 'body blocking', requires absolute precision but can save hundreds of tower hitpoints.
| Troop Type | Aggro Behavior |
|---|---|
| Siege Targeters | Completely ignore all enemy troops, making them incredibly easy to kite across the entire map with cheap structures |
| Melee Assassins | Often have dash abilities that lock onto targets from far away; must be intercepted before the dash animation begins |
Drilling the Mechanics
Reading about aggro ranges is completely different from actually executing pixel-perfect placements in the heat of a live match.
Control the aggro, control the arena.
