Unreal Engine 4 - NavigationMesh & Dijkstra pathfinding on a Spline's Graph
Quick explanation of what's going on... The Target is:
// White case
Not on the NavMesh
Probably reachable via a Spline but the furthest point on the NavMesh pointing the closest SplinePoint is not reachable
- Random location at 75% of the NavMesh Invoker Radius
// Green case
Not on the NavMesh
Probably reachable via a Spline and the furthest point on the NavMesh pointing the closest SplinePoint is reachable
- Furthest point on the NavMesh pointing the closest SplinePoint
// Blue case
Not on the NavMesh
Probably reachable via a Spline and the furthest point on the NavMesh pointing the closest SplinePoint is on the NavMesh
- Furthest point on the NavMesh and on the Spline
// Yellow case
Not on the NavMesh
Distance to the Segment (Target - ClosestSplinePointFromTarget) is inferior of the InvokerRadius
- Furthest point on the NavMesh pointing to the Target
// No debug sphere
On the NavMesh
