RaycastGround

Analytic ray against the ground: no physics scene, never hits anything but ground.

Declaration

UFUNCTION(BlueprintCallable, Category="Orrery|Terrain|Query", meta=(AutoCreateRefTerm="Start,End"))
bool RaycastGround(const FVector& Start, const FVector& End, FVector& OutPoint, FVector& OutNormal,
                   EOrreryTerrainSurface Surface = EOrreryTerrainSurface::Modified) const;

- In Target (self object): self
- In Start (Vector): (0.0, 0.0, 0.0)
- In End (Vector): (0.0, 0.0, 0.0)
- In Surface (EOrreryTerrainSurface): Modified

Module: PublicDependencyModuleNames.Add("OrreryTerrain"); in your module’s Build.cs.
Stability: Stable: changes within a major version only add.
Thread: Every member function is game thread unless it says otherwise. (the rule of UOrreryTerrainSubsystem)
Blueprint: Raycast Ground, in Orrery › Terrain › Query

Parameters

Name	Type	Default	Meaning
`Start`	`const FVector&`	—	World positions, cm.
`End`	`const FVector&`	—	World positions, cm.
`OutPoint`	`FVector&`	—	Hit position, cm.
`OutNormal`	`FVector&`	—	Unit normal, Z up.
`Surface`	`EOrreryTerrainSurface`	`EOrreryTerrainSurface::Modified`	Which ground to trace: Modified (the default) is the ground as edited.

Returns

true on a hit between Start and End.
