# Ray Cast

Node description and basic instructions

### Description

Casts a ray, from point origin, in direction direction, of length max Distance, against all colliders in the Scene.

Specifying Query Trigger Interaction allows you to control whether or not Trigger colliders generate a hit.

{% hint style="warning" %}
Raycasts will not detect Colliders for which the Raycast origin is inside the Collider.
{% endhint %}

{% hint style="info" %}
**bool** Returns true if the ray intersects with a Collider, otherwise false.
{% endhint %}

**To create it**, right-click on free space in AI Tree inspector and select <mark style="color:purple;">Create Node/Tasks/Physics/Ray Cast.</mark>
