[Solved] Make units only attack what is on their path and ignore the rest ?

[FortuneDW]

I'm making a wave-based tower defense game.

Enemy units spawn at the right of the map and are ordered to Attack-Move toward a region at the left.

My goal is for them to attack any enemy they encounter along their path while moving toward their destination.

The problem is that whenever a defensive building attacks one of these units, the unit immediately abandons its current target and rushes toward the building that attacked it. It seems there's a built-in retaliation/aggro system that gives priority to the source of incoming damage.

Is there a way to disable or ignore this retaliation behavior so units simply attack whatever is directly in their path instead of chasing whatever attacked them? I'd like to avoid making defensive structures invulnerable because those defensive structures should also be attacked when they are in the path.

Thanks in advance

Welcome to the Hive,

you might get somewhat decent results, by altering the gameplay constants for aggro range and lowering the acquisition range of your spawns drastically. Sadly, the constants would affect all units.

I think a better way to do this without fighting with the built-in target acquisition is by just using walk commands and not attack ground. then you will need to set up a separate system to check if their path is blocked, and if so - attack the blocking unit. there are already some existing systems that can probably help you out with this - check the spells and systems section. (one example - IsPointWalkable)

Wonderful, i played a bit with the acquisition range by toning it up/down and found the sweet spot. Thanks a lot !
