VR Look-At Trigger
Method #
This node allows you to create effects based on what the VR user is looking at. The target is a cuboid region specified by the scale and position.
When the user looks at the defined space, the Current Value parameter will increase (at a rate defined by Required Hit Duration).
All nodes connected to this node are treated as if flowing to the parent node, and inherits any transformation changes along the chain. When connected to an Extractor modifier, you can use the Current Value / Current Value With Button to activate and control other nodes and effects.
Parameters
These properties control the 3D transforms of the node. Transforms will generally be inherited by child nodes, although they can be ignored through the Inherit Transform Channels attributes.
Parameter Details
Position X Move along the local x-axis.
Position Y Move along the local y-axis.
Position Z Move along the local z-axis.
Rotation Heading Rotate around the local y-axis.
Rotation Pitch Rotate around the local x-axis.
Rotation Bank Rotate around the local z-axis.
Scale X Scale along the local x-axis.
Scale Y Scale along the local y-axis.
Scale Z Scale along the local z-axis.
Toggle which transform channels should be inherited from the parent node. By default, all transforms will be inherited.
Parameter Details
Position X Toggle inheritance of the X Position from the parent.
Position Y Toggle inheritance of the Y Position from the parent.
Position Z Toggle inheritance of the Z Position from the parent.
Rotation Heading Toggle inheritance of the Rotation Heading from the parent.
Rotation Pitch Toggle inheritance of the Rotation Pitch from the parent.
Rotation Bank Toggle inheritance of the Rotation Bank from the parent.
Scale X Toggle inheritance of the X Scale from the parent.
Scale Y Toggle inheritance of the Y Scale from the parent.
Scale Z Toggle inheritance of the Z Scale from the parent.
World Position Only Inherit the world position from the parent only, rotation and scale will be ignored. Overrides above properties.
Inherit Time Toggle inheritance of time from the parent.
These properties control the core behaviours of the node.
Parameter Details
Current Value Value moves from 0.0 to 1.0 as the VR user looks at the target. Speed is set by Required Hit Duration.
Current Value With Button Value moves from 0.0 to 1.0 as the VR user looks at the target, but increases greatly when a button is pressed. Speed is set by Required Hit Duration With Button.
Required Hit Duration The time it takes for the current value to move from 0.0 to 1.0, while the user is looking at the target.
Required Hit Duration With Button The time it takes for the current value with button to move from 0.0 to 1.0, while the user is looking at the target.
Lookat Speed Multiplier Modify how quickly the Lookat Speed increases on the Current Value With Button.
Check VR Controllers Enable / Disable the Vr Controllers to be checked if pointing to target.
These properties control how the hit point is visualised, useful for debugging.
Parameter Details
Show Hit Points Enable/Disable Hit Point images.
Hit Point Size Size of the Hit Point image.
Hit Point Alpha Alpha of the Hit Point image.
Hit Point Colour Tint the colour of the Hit Point image.
Hit Point Image Select an image to be shown when the nodes is activated. Will be overwritten by input nodes.
