# Sphere Cast

Node description and basic instructions

### Description

Casts a sphere along a ray and returns detailed information on what was hit.

This is useful when a Raycast does not give enough precision, because you want to find out if an object of a specific size, such as a character, will be able to move somewhere without colliding with anything on the way. Think of the sphere cast like a thick raycast. In this case the ray is specified by a start vector and a direction.

{% hint style="warning" %}
Sphere Cast will not detect colliders for which the sphere overlaps the collider. Passing a zero radius results in undefined output and doesn't always behave the same as [Raycast](/ai-tree/nodes/tasks/physics/ray-cast.md)
{% endhint %}

{% hint style="info" %}
**bool** True when the sphere sweep intersects any collider, otherwise false.
{% endhint %}
