MoveBy Action

Overview

The MoveBy Action Node.

The MoveBy Action Node continuously modifies the Position of an Object by the values specified in Offset for a given period of time, thus creating an Animation. Find an example of how to use this Node and its effect over an Object at the end of this page.

Furthermore, visit the Actions Nodes page for a general introduction to these Nodes, and Position for more detail about the Position Attribute.

Scope: Scene, Function, Prefab.

Attributes

The MoveBy Action Node Attributes.

Attribute	Type	Description
Offset	Vector3	The amount to modify the Position of an Object along the X, Y, Z axes, if none is given in the Offset Input Socket.
Duration (sec)	Float	The total time of the Action, if none is given in the Duration Input Socket.
Interpolation	Drop-down	The Interpolation method to use for calculating the intermediate values of the Position. It can be Linear, Sine Ease In, Sine Ease In Out, or Sine Ease Out.

Inputs

Input	Type	Description
Instance ID	InstanceID	The assigned Instance ID of the Action. If nothing is received, it automatically assigns 0 as the Instance ID.
(►) Start	Pulse	A standard Input Pulse, to trigger the execution of the Node.
Object ID	ObjectID	The ID of the target Object.
Duration	Float	The total time (in seconds).
Offset	Vector3	The amount to move the Position of an Object along the X, Y, Z axes.

Outputs

Output	Type	Description
Instance ID	InstanceID	The assigned Instance ID of the Action.
OnStart (►)	Pulse	Flows to the next Node following MoveBy Action when the Action starts.
OnEnd (►)	Pulse	Flows to the next Node following MoveBy Action when the Action stops.

Example

This section shows a simple example of how to use the MoveBy Action Node and the effect it has on an Object. We start by configuring the Scene, then build the Logic, and finally show the result.

Scene Configuration

We consider a Scene with two Objects: a red arc over a black background, both of which can be easily created in the Scene Outliner. Then, we set the Size Attribute of the arc to $(150, 150, 1)$. See this configuration in the following image:

Scene configuration.

Logic

We then need to configure the Logic. This is done in the Logic Editor.

We use the MoveBy Action Node with the following Attributes:

• To: $(-200, -200, 0)$
• Duration (sec): $3$
• Interpolation: Linear

And we connect to it the Object Node of the red arc and a Pulse to the Start Input Socket. Thus, having the following Logic configuration:

Logic configuration.

Final result

Finally, the effect of the ScaleTo Action Node when triggered is the following:

Final result.
