UKismetSystemLibrary::DrawDebugCylinder

function Engine Blueprint Since 4.0

#include "Kismet/KismetSystemLibrary.h"

Access: public Specifiers: staticUFUNCTIONBlueprintCallable

Description

Draws a wireframe cylinder between two points, useful for visualizing capsule collision without the hemisphere caps or a custom volume shape.

Caveats & Gotchas

• Start and End define the centers of the two flat caps, so the cylinder's total height is the distance between them — it does not take a separate height parameter.
• Compiled out entirely in Shipping and Test builds since the UFUNCTION is DevelopmentOnly.

Signature

static void DrawDebugCylinder(const UObject* WorldContextObject, const FVector Start, const FVector End, float Radius=100.f, int32 Segments=12, FLinearColor LineColor = FLinearColor::White, float Duration=0.f, float Thickness = 0.f, EDrawDebugSceneDepthPriorityGroup DepthPriority = EDrawDebugSceneDepthPriorityGroup::World)

Parameters

Name	Type	Description	Default
WorldContextObject	const UObject*	World context used to resolve which world to draw in.	—
Start	const FVector	World-space center of one cap of the cylinder.	—
End	const FVector	World-space center of the other cap of the cylinder.	—
Radius	float	Radius of the cylinder.	100.f
Segments	int32	Number of segments used to approximate the circular cross-section.	12
LineColor	FLinearColor	Color of the drawn cylinder.	FLinearColor::White
Duration	float	How long the cylinder persists, in seconds. 0 draws for a single frame.	0.f
Thickness	float	Line thickness in screen pixels.	0.f
DepthPriority	EDrawDebugSceneDepthPriorityGroup	Whether the cylinder is depth-tested against the scene or always drawn in the foreground.	EDrawDebugSceneDepthPriorityGroup::World

Return Type

void

Example

Draw a vertical cylinder C++

const FVector Base = GetActorLocation();
UKismetSystemLibrary::DrawDebugCylinder(
    this,
    Base,
    Base + FVector(0, 0, 200.f),
    50.f,
    16,
    FLinearColor::Blue,
    2.0f);
