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.
Use this to pull them to the center.Melee units have very short sight ranges.Always account for the unit's movement speed. The Geometry of Defense
Large tanks have massive hitboxes, meaning melee defenders can attack them from slightly further away than smaller troops.

The physical mass of the tank will actually push the Miner backward, forcing him to lose range on the tower and retarget onto the tank.
Character ClassTargeting StyleBuilding ChasersCompletely ignore all enemy troops, making them incredibly easy to kite across the entire map with cheap structuresMelee AssassinsOften 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.
