rcFilterLowHangingWalkableObstacles

Marks non-walkable spans as walkable if their maximum is within `walkableClimp_ of a walkable neighbor.

Windows

MacOS

Linux

Warnings

Will override the effect of rcFilterLedgeSpans. So if both filters are used, call rcFilterLedgeSpans after calling this filter.

Syntax

void rcFilterLowHangingWalkableObstacles
(
    rcContext * ctx,
    const int walkableClimb,
    rcHeightfield & solid
)

Remarks

Marks non-walkable spans as walkable if their maximum is within `walkableClimp_ of a walkable neighbor.

Allows the formation of walkable regions that will flow over low lying objects such as curbs, and up structures such as stairways.

Two neighboring spans are walkable if: `rcAbs(currentSpan.smax - neighborSpan.smax) < waklableClimb_

Will override the effect of rcFilterLedgeSpans. So if both filters are used, call rcFilterLedgeSpans after calling this filter.

Parameters

Parameter	Description
ctx	The build context to use during the operation.
walkableClimb	Maximum ledge height that is considered to still be traversable. [Limit: >=0] [Units: vx]
solid	A fully built heightfield. (All spans have been added.)
