# Step Trigger

✔

This script uses the **OnTriggerEnter** callback to detect if the feet of the animal is colliding with the **Ground Layer,** from the  [**Steps Manager**](/animal-controller/utilities/steps-manager.md). It will send upwards to the [**Steps Manager**](/animal-controller/utilities/steps-manager.md) where the contact was made so it can place the **tracks, dust particles** and play a **step sound**.
