Operating Form Builder

This section offers detailed step-by-step information on utilizing the Form Builder for beginners. Departing from the information provided in this section, you can drive more complex scenarios independently.

This section uses the MainLevel map of the RealityExamples template, compatible with Reality Engine version 4.27. It is the default project that comes with a fresh installation. After launching the Reality Editor, you can create the same project through the Virtual Studio template. For more details, visit Reality Starter Projects.

Please keep that in mind; to see the results of your template Forms, you must use the Playout module.

Preparing Action

Example Node Tree along with the activated APM

• Activate the Nodegraph/Actions tab

• Create the node tree as shown in the image above
• Activate the APM

• Activate the Actions tab, click on the New Action button, rename it if you like

• Select the UserTrack_0 node, go to its Properties panel, find the UserTransform property under the Input property group
• Hover your mouse over the UserTransform​ property circle, right-click on it, and select the Timeline.

• Go to the first frame in the Action Timeline, right-click on the UserTransform property circle, and select the Add Keyframe.

• Go to the third second in the Timeline, and change the UserTransform property values using the GamePad feature.
• Right-click on the circle of the UserTransform property, select the Get Value option, then right-click again and this time select the Add Keyframe.

• While the second keyframe is selected, go to the Animation Interpolation, and change the interpolation type to EaseInEaseOut.

• Go to the Actions Menu and Save it

Your setup must look like in the image above.

Now:

UserTransform Property Inside the Action Timeline

• Go to the Action tab, click on the Add button, create a New Action, and rename it if you like

• Repeat the same process twice with different UserTransform values

As the image above shows, we have three different Action animations (Cam 1, Cam 2, and Cam 3) of the same UserTransform.

Now it is time to design our template form via Form Builder.
