When the user reaches that step, VR Builder automatically calls the selected function.<\/li>\n<\/ol>\n\n\n\n<p class=\"wp-block-paragraph\">For example, a designer could select a door GameObject and choose its <code>Open()<\/code> function. When the learner completes the designated step, the door opens automatically\u2014without the designer needing to write any code or manually configure an event listener.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Behind the scenes, the C# script does the heavy lifting.<\/strong> It uses reflection to discover eligible public methods on the target GameObject&#8217;s components, filters out Unity and VR Builder framework methods, and presents the available functions in the Step Inspector. It then saves the target object reference, component type, and selected method name so it can locate and invoke the correct method when the step activates.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The Behavior also supports coroutine-based methods, provides error reporting when a selected method can no longer be found, and executes during step skipping or fast-forwarding to help maintain workflow consistency.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The real benefit is separating <strong>building functionality from using functionality<\/strong>. Developers can create custom interactions in C# once, and instructional designers can reuse them throughout a VR training experience through a simple visual interface.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">This approach expands what&#8217;s possible with VR Builder while making more advanced, customized VR learning experiences accessible to people who may not have programming experience.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>I&#8217;ve been extending the capabilities of Unity&#8217;s VR Builder by developing custom Behaviors in C# that make it easier to create interactive VR experiences and training simulations.
