SCNActionMBS.fadeIn(duration as double) as SCNActionMBS

Type	Topic	Plugin	Version	macOS	Windows	Linux	iOS	Targets
shared method	SceneKit	MBS Mac64bit Plugin	19.1	✅ Yes	❌ No	❌ No	✅ Yes	Desktop & iOS

Creates an action that changes the opacity of the node to 1.0.

duration: The duration, in seconds, of the animation.

Returns a new action object.

When the action executes, the node’s opacity property animates from its current value to 1.0.
This action is reversible; the reverse is created as if the following code had been executed:

SCNActionMBS.fadeOut(Duration)

Some examples using this method:

• /Mac64bit/SceneKit/SceneKit Images

SCNActionMBS.fadeOpacityBy(factor as double, duration as double) as SCNActionMBS

Type	Topic	Plugin	Version	macOS	Windows	Linux	iOS	Targets
shared method	SceneKit	MBS Mac64bit Plugin	19.1	✅ Yes	❌ No	❌ No	✅ Yes	Desktop & iOS

Creates an action that adjusts the opacity of a node by a relative value.

factor: The amount to change the node’s opacity by.
duration: The duration, in seconds, of the animation.

Returns a new action object.

When the action executes, the node’s opacity property animates to its new value.
This action is reversible; the reverse is created as if the following code had been executed:

SCNActionMBS.fadeOpacityBy(-factor, duration)

SCNActionMBS.fadeOpacityTo(opacity as double, duration as double) as SCNActionMBS

Type	Topic	Plugin	Version	macOS	Windows	Linux	iOS	Targets
shared method	SceneKit	MBS Mac64bit Plugin	19.1	✅ Yes	❌ No	❌ No	✅ Yes	Desktop & iOS

Creates an action that adjusts the opacity of a node to a new value.

opacity: The new opacity value of the node.
duration: The duration, in seconds, of the animation.

Returns a new action object.

When the action executes, the node’s opacity property animates to its new value.
This action is not reversible; the reverse of this action has the same duration but does not change anything.

SCNActionMBS.fadeOut(duration as double) as SCNActionMBS

Type	Topic	Plugin	Version	macOS	Windows	Linux	iOS	Targets
shared method	SceneKit	MBS Mac64bit Plugin	19.1	✅ Yes	❌ No	❌ No	✅ Yes	Desktop & iOS

Creates an action that changes the opacity of the node to 0.0.

duration: The duration, in seconds, of the animation.

Returns a new action object.

When the action executes, the node’s opacity property animates from its current value to 0.0.
This action is reversible; the reverse is created as if the following code had been executed:

SCNActionMBS.fadeIn(duration)

Some examples using this method:

• /Mac64bit/SceneKit/SceneKit Images

SCNActionMBS.group(actions() as SCNActionMBS) as SCNActionMBS

Type	Topic	Plugin	Version	macOS	Windows	Linux	iOS	Targets
shared method	SceneKit	MBS Mac64bit Plugin	19.1	✅ Yes	❌ No	❌ No	✅ Yes	Desktop & iOS

Creates an action that runs a collection of actions in parallel.

actions: An array of SCNActionMBS objects.

Returns a new group action object.

When the action executes, the actions that make up the group all start immediately and run in parallel. The duration of the group action is the longest duration among the collection of actions. If an action in the group has a duration less than the group’s duration, the action completes and then idles until the group completes the remaining actions. This matters most when creating a repeating action that repeats a group.
This action is reversible; it creates a new group action that contains the reverse of each action specified in the group.

SCNActionMBS.hide as SCNActionMBS

Type	Topic	Plugin	Version	macOS	Windows	Linux	iOS	Targets
shared method	SceneKit	MBS Mac64bit Plugin	19.1	✅ Yes	❌ No	❌ No	✅ Yes	Desktop & iOS

Creates an action that hides a node.

When the action executes, the node’s hidden property is set to true.
This action is reversible; the reverse is equivalent to the unhide action.

SCNActionMBS.javaScriptActionWithScript(script as string, duration as double) as SCNActionMBS

Type	Topic	Plugin	Version	macOS	Windows	Linux	iOS	Targets
shared method	SceneKit	MBS Mac64bit Plugin	19.1	✅ Yes	❌ No	❌ No	✅ Yes	Desktop & iOS

Creates an action that executes a JavaScript script periodically over a specified duration.

script: A string containing JavaScript source code.
seconds: The duration of the action, in seconds.

SceneKit exposes its classes, methods, and functions in the JavaScript context that runs the script—see the SCNJavaScript.h header file for details.

When the action executes, SceneKit runs the script repeatedly until the action’s duration expires. Each time SceneKit runs the script, it computes the elapsed time since the action began executing (as a fraction of the action’s duration between 0.0 and 1.0) and makes it available to the script as a variable named elapsedTime. The script can also reference the SCNNode object running the action as a variable named node.
This action is not reversible; the reverse action executes the same script.

SCNActionMBS.moveBy(delta as SCNVector3MBS, duration as double) as SCNActionMBS

Type	Topic	Plugin	Version	macOS	Windows	Linux	iOS	Targets
shared method	SceneKit	MBS Mac64bit Plugin	19.1	✅ Yes	❌ No	❌ No	✅ Yes	Desktop & iOS

delta: A vector that describes the change to be applied to the node’s position.
duration: The duration, in seconds, of the animation.

Returns a new action object.

When the action executes, the node’s position property animates from its current position to its new position.
This action is reversible; the reverse is created as if the following code had been executed:

dim reverseDelta as SCNVector3MBS = SCNVector3MBS.Vector(-delta.x, -delta.y, -delta.z)
SCNActionMBS.moveBy( reverseDelta, duration)

deltaZ: The distance to move the node in the Z direction of its parent node’s local coordinate space.
duration: The duration, in seconds, of the animation.

Returns a new action object.

When the action executes, the node’s position property animates from its current position to its new position.
This action is reversible; the reverse is created as if the following code had been executed:

duration: The duration, in seconds, of the animation.

Returns a new action object.

Type	Topic	Plugin	Version	macOS	Windows	Linux	iOS	Targets
shared method	SceneKit	MBS Mac64bit Plugin	19.1	✅ Yes	❌ No	❌ No	✅ Yes	Desktop & iOS

Creates an action that repeats another action a specified number of times.

action: The action to be executed.
count: The number of times to execute the action.

Returns a new action object.

When the action executes, the associated action runs to completion and then repeats, until the count is reached.

Creates an action that repeats another action forever.

action: The action to execute.

Returns a new action object.

When the action executes, the associated action runs to completion and then repeats.
