Food Truck Blueprints

Demo

Place one of the food truck blueprints in the scene and run the game. Press "O" to open the food truck elements and "C" to close them. The section marked as DEMO in the Blueprint's EventGraph can be safely removed if not needed.

Information

Each of the four food trucks has some movable elements: doors, shutters, and optionally a window. There are events exposed to be called by external functions to open/close those elements of the food truck.

Opening/closing over time uses Timelines and the opposite method can be safely called before the previous rotation finishes - the element will reverse the rotation appropriately.

Adjustable parameters allow for setting the time it takes for the element to open/close and how widely it opens when the open method is called on it.

Callable Events

• OpenDoor, CloseDoor, OpenWindow, CloseWindow, OpenShutters, CloseShutters - to be called at runtime to fully open/close the respective elements over time

• UpdateDoorWindowShuttersInEditor - to be called in the Editor mode to update the actor model to how much open (percentage-wise) the doors, windows, and shutters elements are according to the DoorOpenPercent, WindowOpenPercent, and ShuttersOpenPercent values edited on the Actor

Adjustable Parameters

• DoorOpenPercent, ShuttersOpenPercent, WindowOpenPercent - editable on Actor instance in the Editor. Call UpdateDoorWindowShuttersInEditor in Editor to update the Actor on the scene in the Editor mode.

• TimeFromClosedToOpen - the time in seconds it should take for the elements to open fully from closed state and close fully from open state. Default value: 2.0s

• Door/Window/Shutters MinAngle and MaxAngle - local variables for SetDoorOpen, SetWindowOpen, and SetShuttersOpen methods. Adjust the MaxAngle to change how wide (in degrees) the element opens when open at 100% by SetDoorOpen, SetWindowOpen, SetShuttersOpen. The default values reasonably represent the elements when fully open without colliding with other elements of the food truck. Adjust the MinAngle if you don't want the element to close fully when closed - default value of 0.0 degrees represents the elements when fully closed, matching the food truck frame.

Internal Methods

• SetDoorOpen, SetShuttersOpen, SetWindowOpen - internal methods called to set the respective element's rotation at runtime and in Editor according to the given OpenPercent value.

• SetOpeningDuration - internal method called on Event BeginPlay. It sets the PlayRate of the relevant timelines to reflect how long it should take for the elements to open fully from closed state and close fully from open state.

• SetMovingPartsState - internal method called at runtime on Event BeginPlay or in the Editor through UpdateDoorWindowShuttersInEditor event. It sets the angle of all food truck elements instantly.
