In the chaotic environment of a competitive arena battler, units seem to run wildly toward whatever is closest to them.
This article will dissect the mathematics of sightlines, retargeting, and unit hitboxes to help you manipulate the AI flawlessly.
The Concept of Sight Range
If multiple enemies are within that radius, the AI will almost always lock onto the absolute closest target mathematically.
If a massive, slow-moving tank is lumbering toward your tower, you do not need to place your defense directly in front of it.
- Use the arena tiles as a visual guide.
- You must use a stun spell (like Zap) to force it to rescan.
- Adjust your placements for air threats.
The Geometry of Defense
One of the most complex aspects of aggro management involves understanding the physical size, or ‘hitbox’, of different units.
For example, if an enemy Miner is locked onto your tower, you can deploy a large tank directly on top of him.
| Character Class | Targeting Style |
|---|---|
| Tower Hunters | 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 |
Practice Makes Perfect
Reading about aggro ranges is completely different from actually executing pixel-perfect placements in the heat of a live match.
You will no longer panic when a massive push approaches; you will simply calculate the optimal placement and watch the AI dance to your tune.
