Introduction

XRCC PC offers a block-based graphical user interface with a large library of built-in operators, control flows, events, and actions, that allow you to put together the flow of the behaviours in a visual manner, without needing to write a line of code.

Below is a list of behaviour block categories accessible by all object types:

Icon	Description
	Provides behaviour blocks as a starting point to trigger execution, including scene starting and controller event.
	Provides behaviour blocks for sound controls, including playing and pausing.
	Provides behaviour blocks for scene controls, including fading effect transition and scene changing.
	Provides behaviour blocks for user controls, including user movement and travel destination.
	Provides behaviour blocks to control the execution flow, including branching, looping, and waiting for a certain condition or amount of time.
	Provides behaviour blocks to measure time, including timer and stopwatch control.
	Provides behaviour blocks for controlling variables including get and set scenes and item variables.
	Provides behaviour blocks for math-based operations, including value assignment, mathematical calculation, and logical control.
	Provides behaviour blocks for controlling project wide variables.
	Provides behaviour blocks for string-based operations, including string manipulation and comparison.
	Provides behaviour blocks for using Wit.ai with XRCC.
	Provides behaviour blocks for controlling a Microbit circuit board from XRCC.

There are also object-specific behaviour blocks only accessible by objects of certain types:

Icon	Available Object Type	Description
	All object types except Scene	Provides behaviour blocks that use item interaction to trigger execution, including pointing, touching and clicking object.
	All object types except Scene	Provides behaviour blocks that determines whether an item can be grabbed or interacted with, and whether it should be shown.
	All object types except Scene	Provides behaviour blocks that perform an action on the chosen object, including move, rotate, and scale.
	All object types except Scene	Provides behaviour blocks related to display effect on an item, including outline, overlay, and blinker.
	All object types except Scene and Light Object	Provides behaviour blocks related to physical interactions.
	3D Model	Provides behaviour blocks to control model, including animation, material and grabbing.
	2D/3D Image	Provides behaviour blocks to control Image object, including setting image.
	2D/3D Video	Provides behaviour blocks to control Video object, including pause and stop video.
	Document	Provides behaviour blocks to control Document object, including changing page.
	Text	Provides behaviour blocks to control Text object, including setting text.
	Character	Provides behaviour blocks to control Character object, including motion and voice.
	Option Box	Provides behaviour block to hide option box.
	Light	Provides behaviour blocks to control light.
	2D Slideshow	Provides behaviour blocks to control 2D slideshow.
	3D Slideshow	Provides behaviour blocks to control 3D slideshow.
	Button	Provides behaviour blocks to control button object, including setting button's color.
	Empty Object	Provides behaviour blocks to control collider of the empyty object as wall.
