Syntax

int findCorners
(
    float * cornerVerts,
    unsigned char * cornerFlags,
    dtPolyRef * cornerPolys,
    const int maxCorners,
    dtNavMeshQuery * navquery,

    float pathOffsetDistance,
    float earlyReachDistance,
    bool bAllowEarlyReach
)

Remarks

Finds the corners in the corridor from the position toward the target. (The straightened path.)

This is the function used to plan local movement within the corridor. One or more corners can be detected in order to plan movement. It performs essentially the same function as dtNavMeshQuery::findStraightPath.

Due to internal optimizations, the maximum number of corners returned will be (`maxCorners_ - 1) For example: If the buffers are sized to hold 10 corners, the function will never return more than 9 corners. So if 10 corners are needed, the buffers should be sized for 11 corners.

If the target is within range, it will be the last corner and have a polygon reference id of zero.

Returns

The number of corners returned in the corner buffers. [0 <= value <= `maxCorners_]

Parameters

Parameter	Description
cornerVerts	The corner vertices. [(x, y, z) * cornerCount] [Size: <= maxCorners]
cornerFlags	The flag for each corner. [(flag) * cornerCount] [Size: <= maxCorners]
cornerPolys	The polygon reference for each corner. [(polyRef) * cornerCount] [Size: <= maxCorners]
maxCorners	The maximum number of corners the buffers can hold.
navquery	The query object used to build the corridor.
filter	The filter to apply to the operation.
pathOffsetDistance	[UE4] Radius for path offsetting
earlyReachDistance	[UE4] Radius for early reach detection
bAllowEarlyReach	[UE4] Check if corner skipping for EarlyReachTest is available now
