function
UButton::GetTouchMethod UMG

Returns the touch action currently required to trigger the button's click on touch input devices.

property
UCharacterMovementComponent::MaxTouchForce Engine

Upper bound on the force applied to physics objects the character touches, computed from TouchForceFactor.

property
UCharacterMovementComponent::MinTouchForce Engine

Lower bound on the force applied to physics objects the character touches, computed from TouchForceFactor.

function
AActor::NotifyActorOnInputTouchBegin Engine

Called when this actor is touched by a finger when click events are enabled in the PlayerController.

function
AActor::NotifyActorOnInputTouchEnd Engine

Called when a finger is lifted off this actor when click events are enabled in the PlayerController.

function
AActor::NotifyActorOnInputTouchEnter Engine

Called when a touch finger moves onto this actor while touch-events are enabled, analogous to NotifyActorBeginCursorOver but for touchscreen input.

function
AActor::NotifyActorOnInputTouchLeave Engine

Called when a touch finger moves off this actor while touch-events are enabled.

property
AActor::OnInputTouchBegin Engine

Delegate fired when a touch input begins over this actor while touch events are enabled in the player controller.

property
AActor::OnInputTouchEnd Engine

Delegate fired when a touch input that began over this actor is released, while touch events are enabled in the player controller.

property
AActor::OnInputTouchEnter Engine

Delegate fired when a finger moves onto this actor's touch area while a touch is already active and touch over events are enabled in the player controller.

property
AActor::OnInputTouchLeave Engine

Delegate fired when a moving finger leaves this actor's touch area while a touch is active and touch over events are enabled in the player controller.

function
UKismetInputLibrary::PointerEvent_GetTouchpadIndex Engine

Returns which touchpad generated this event, for platforms and controllers that expose more than one touch surface per user.

function
UKismetInputLibrary::PointerEvent_IsTouchEvent Engine

Returns true if this pointer event originated from a touch input rather than a mouse.

function
AActor::ReceiveActorOnInputTouchBegin Engine

Blueprint implementable event called when a touch input begins on this actor.

function
AActor::ReceiveActorOnInputTouchEnd Engine

Blueprint implementable event called when a touch input ends over this actor.

function
AActor::ReceiveActorOnInputTouchEnter Engine

Blueprint implementable event called when an active touch point moves onto this actor's area.

function
AActor::ReceiveActorOnInputTouchLeave Engine

Blueprint implementable event called when an active touch point moves off this actor's area.

function
UButton::SetTouchMethod UMG

Sets which touch interaction pattern triggers the button's OnClicked event on touch-input platforms.

function
UKismetMathLibrary::Box_IsInside Engine

Returns true only when InnerTest is completely contained within OuterTest, with no part touching or crossing the outer boundary.

function
UKismetMathLibrary::Box_IsPointInside Engine

Tests whether a world-space point lies strictly inside an axis-aligned bounding box.

function
UKismetRenderingLibrary::ImportBufferAsTexture2D Engine

Decodes an in-memory image buffer and creates a new transient Texture2D from it, without touching disk.

function
UKismetInputLibrary::Key_IsAxis2D Engine

Returns true if the key is a 2D (vector) axis, such as mouse movement or a touchpad's XY position.

function
UKismetMathLibrary::Matrix_GetMatrixWithoutScale Engine

Returns a copy of the matrix with scale removed — each row is normalised to unit length.

function
ACharacter::OnLanded Engine

Blueprint-implementable event fired automatically by Landed() when the character touches down.

function
UKismetInputLibrary::PointerEvent_GetGestureType Engine

Returns the type of trackpad/touch gesture — Scroll, Magnify, Swipe, Rotate, or LongPress — associated with this pointer event.

function
UKismetInputLibrary::PointerEvent_GetPointerIndex Engine
