Zombies collide with a fence barrier using a trigger collider and push it until a set limit, at which point the fence becomes invisible and allows zombies to pass.

Apply not mesh obstacle to stationary objects to carve holes in the nav mesh, teaching the zombie to avoid barrels, boxes, and wrecks rather than walking through them.

Set up spikes and a saw as traps in a Unity zombie tower defence game, configure triggers and tags, adjust animations, and create a rotate script to spin the saw.

the turret script shows writing a c# script to target the closest zombie within 20 meters using an items array and zombie tag, with dying state and particle effects.

Attach a 3D spatial audio source to gun turrets in Unity, loop a WAV clip, and control volume. Destroy turrets when ammo runs out, syncing audio with zombies.

set up a zombie spawn point and a spawn script in unity to spawn zombies at intervals from a defined point. test with barricades and weapons while tracking total spawns.

Standardize zombie setup in a Unity zombie tower defence game by copying components and values from zombie four to zombies two, three, five, and six, including prefabs and particle effects.
