# 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**](https://malbersanimations.gitbook.io/animal-controller/utilities/steps-manager). It will send upwards to the [**Steps Manager**](https://malbersanimations.gitbook.io/animal-controller/utilities/steps-manager) where the contact was made so it can place the **tracks, dust particles** and play a **step sound**.
