class UPCGPathfindingSettings : public UPCGSettings

Remarks

Finds the optimal path across the points of a given point cloudshould one existwhen provided a start and goal location, and a maximum jump distance between points. Can return a partial path.

Variables

  Type Name Description
Public variable UProperty Category, EditAnywhere, Meta BlueprintReadWrite bool bAcceptPartialPath Even if the path is not complete, return a viable partial path to the point closest to the goal.
Public variable UProperty Category, EditAnywhere, Meta BlueprintReadWrite bool bCopyOriginatingPoints Copy the properties and attributes from the originating point input to the output points.
Public variable UProperty Category, EditAnywhere BlueprintReadWrite bool bGoalLocationsAsInput  
Public variable UProperty Category, EditAnywhere BlueprintReadWrite bool bOutputAsSpline The final path will be a spline. If false, the final path will be an ordered point data.
Public variable UProperty Category, EditAnywhere BlueprintReadWrite bool bStartLocationsAsInput  
Public variable UProperty Category, EditAnywhere, Meta BlueprintReadWrite bool bUsePathTraces Controls whether raycasts will be used to test for collisions along the path (hit results will be considered obstacles for the pathfinding).
Public variable UProperty Category, EditAnywhere, Meta BlueprintReadWrite FPCGAttributePropertyInputSelector CostAttribute Attribute to use as part of the cost function - it's meaning will depend on the cost function mode (fitness value, scalar multiplier, or else).
Public variable UProperty Category, EditAnywhere, Meta BlueprintReadWrite EPCGPathfindingCostFunctionMode CostFunctionMode Controls whether the cost function will use a given attribute as a scalar wrt to the distance.
Public variable UProperty Category, EditAnywhere, Meta BlueprintReadWrite FVector Goal The location the pathfinding should attempt to reach.
Public variable UProperty Category, EditAnywhere, Meta BlueprintReadWrite FPCGAttributePropertyInputSelector GoalLocationAttribute  
Public variable UProperty Category, EditAnywhere, Meta BlueprintReadWrite double HeuristicWeight The heuristic estimates a faster path to speed up processing.
Public variable UProperty Category, EditAnywhere, Meta BlueprintReadWrite double MaximumFitnessPenaltyFactor Fitness penalty scalar (maximum penalty applied when fitness is zero.)
Public variable UProperty Category, EditAnywhere, Meta BlueprintReadWrite FPCGWorldRaycastQueryParams PathTraceParams  
Public variable UProperty Category, EditAnywhere, Meta BlueprintReadWrite double SearchDistance The max distance from each point to search for the next viable point in the path.
Public variable UProperty Category, EditAnywhere, Meta BlueprintReadWrite EPCGPathfindingSplineMode SplineMode Determines how the output spline's curves will be calculated.
Public variable UProperty Category, EditAnywhere, Meta BlueprintReadWrite FVector Start The location the pathfinding should attempt to reach.
Public variable UProperty Category, EditAnywhere, Meta BlueprintReadWrite FPCGAttributePropertyInputSelector StartLocationAttribute
