Sphere Cast

Node description and basic instructions

Last updated 1 year ago

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.

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

bool True when the sphere sweep intersects any collider, otherwise false.

To create it, right-click on free space in AI Tree inspector and select Create Node/Tasks/Physics/Sphere Cast.

This task node has a number of fields, that are highlighted in picture below.
