How defenses work

[JMYeomans]

Sorry. I tried to search for answer. I'm relative noob.

Do defenses target whatever comes in their range first until they are dead? Or do they ever switch?

To be more to the point, if I launch a Pekka before Golems, and an archer tower locks in on Pekka, will it ever switch?

From what I have observed, it seems that once they have a target, it doesn't switch. Just wanted to ask. I lurk a lot here, but don't talk a lot.

They dont switch. Im not sure how targeting works though. For pekka, once a tesla kills current target, it targets the pekka. For everything else, defense seems random although they love to target heroes.

But I do a lot of raiding with heroes, and if I push troops in front of them, they seem to be cool. Just trying to figure it out. Appreciate the reply.

Once a defense is locked onto a target its on it till its down. That's why golems are so effective. They'll distract every defense leaving the weaker wiz untouched.

Now if only troop ai worked similarly. I'm so sick of being locked onto the th only to be pulled off at the last possible second by some stupid skele or hero. It's so frustrating it's not funny

They attack the nearest target until it dies.
Defenses also change target to the nearest troop after being frozen.
Teslas attack P.E.K.K.A.s
