This system of prioritization is known as ‘aggro’ (aggression), and mastering it is the most critical mechanical skill in the game.
This article will dissect the mathematics of sightlines, retargeting, and unit hitboxes to help you manipulate the AI flawlessly.
The Concept of Sight Range
When a unit is deployed or finishes destroying a target, it scans its specific sight range for the closest valid enemy.
If a massive, slow-moving tank is lumbering toward your tower, you do not need to place your defense directly in front of it.
- Building-targeting units usually have larger sight ranges.
- Place distractions closer to them.
- Always account for the unit’s movement speed.
The Geometry of Defense
One of the most complex aspects of aggro management involves understanding the physical size, or ‘hitbox’, of different units.
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.
| Troop Type | Targeting Style |
|---|---|
| Siege Targeters | Completely ignore all enemy troops, making them incredibly easy to kite across the entire map with cheap structures |
| Fast Attackers | Often have dash abilities that lock onto targets from far away; must be intercepted before the dash animation begins |
Drilling the Mechanics
Have a clanmate repeatedly send the same tank down the lane while you try to pull it to the center using different tiles.
Once you internalize the invisible grid that governs the AI, the game slows down dramatically.
