NavMesh.CalculatePath

public static function CalculatePath(sourcePosition:Vector3,targetPosition:Vector3,areaMask: int,path:NavMeshPath): bool;

Parameters

sourcePositionThe initial position of the path requested.targetPositionThe final position of the path requested.areaMaskA bitfield mask specifying which NavMesh areas can be passed when calculating a path.pathThe resulting path.

Returns

bool True if a either a complete or partial path is found and false otherwise.

Description

Calculate a path between two points and store the resulting path.

This function can be used to plan a path ahead of time to avoid a delay in gameplay when the path is needed. Another use is to check if a target position is reachable before moving the agent.

In contrast to NavMeshAgent.SetDestination, which is asyncronous call, this function calculates the path immeditely. This can be costly operation for very long paths and can cause hiccup in the frame rate. It is recommended to do only a few path finds per frame, for example when evaluating distances to cover points.

The returned path can be used to set the path for an agent using NavMeshAgent.SetPath. The agent needs to be close the starting point for the set path to work.

Parameters

targetPositionThe final position of the path requested.pathThe resulting path.

Returns

bool True if a path is found.

Description

Calculate a path to a specified point and store the resulting path.

This function can be used to plan a path ahead of time to avoid a delayin gameplay when the path is needed. Another use is to check if a target position is reachable before moving the agent.
