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.
Vision and Targeting
If multiple enemies are within that radius, the AI will almost always lock onto the absolute closest target mathematically.

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.
Memorize specific tile locations.If a unit is already locked onto a tower, it will ignore closer targets.Flying units often have different pathing rules. Advanced Aggro Tricks
You can use the physical bulk of your own units to literally push enemy troops out of their preferred path.

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.

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.
