Template Overview

Using the Arcware Pixel Streaming Template Project

Navigation System Overview

The navigation system operates on both mobile and desktop platforms with three modes: Orbit, Fly, and Walk.

Orbit Mode

• Desktop: Right-click and drag to rotate, Middle click and drag to pan, Double right-click to change focus, Mouse scroll to zoom.

• Mobile: One finger drag to rotate, Double tap to change focus, Pinch to zoom, Three-finger drag to pan.

Fly Mode

• Desktop: Use W/A/S/D to move, Left-click to rotate, Q/E for vertical movement, Middle click and drag to pan.

• Mobile: Touch for movement, Drag to rotate.

Walk Mode

• Desktop: Use W/A/S/D to move, Left-click or mouse move to rotate, Spacebar to jump.

• Mobile: Touch for movement, Drag for rotation. Extra actions like jumping might be automated.

Developers can use this framework to ensure a consistent user experience across devices, with room for adjustments based on user feedback.

Project Context: Created with an 'Automotive/Product Design/Manufacturing' template without starter content.

Arcware Specific Assets in the Project

- BP_Arcware_GameMode ( this GameMode contains the reference to BP_Arcware_Pawn and BP_Arcware_Player_Controller ) - BP_Arcware_Pawn ( this Pawn is used for controlling the player camera. All of the settings you will need related to camera movement speed/zooming/panning etc, are editable in the Pawn actor's detail panel, meaning you can tweak the camera movement style without needing to open the blueprint ) - BP_Arcware_Player_Controller ( this Player Controller contains blueprint nodes for handling the Pixel Streaming events/responses. This is where you can send/receive json messages from the Web browser to trigger events in Unreal Engine ) - BP_Arcware_HUD_Hidden_Mouse ( this HUD should be used when your pixel stream has UI provided via the web-browser. In this scenario, you don't need to click any UI in the game so you don't need to show the in-game mouse cursor ) - BP_Arcware_HUD_Visible_Mouse ( this HUD should be used when your pixel stream has in-game UI. In this scenario, the user needs to interact with the in-game UI so the in-game mouse cursor must be visible. When this HUD is used it provides an example of in-game UI, which shows the most useful functionality for the in-game mouse, such as, only showing the mouse cursor when the menu is open )
