Create An Action That Adds Force To An Object
This guide provides instructions for setting up the EntityRigidbodyAddForceInPhysics action. In the sample app, once the avatar enters the blue trigger area, a force is applied to the sphere.
The sphere is not moving before the avatar enters the trigger area.
Once the avatar enters the trigger area, a force is applied to the sphere in the direction based on the parameters.
In this example, a trigger is created and when the avatar or other objects enters the trigger area, an action adds force to an object. Any object can be used as a trigger, as long as the object has a collision component. This example uses a 3D box as the trigger area.
A. Create a new 3D Box entity.
B. This Collision component is not required for the EntityRigidbodyAddForceInPhysics action to work. The Collision component is required for the EntitySubscribeTriggerEnter trigger that will be used in this example.
C. Adding a material is optional. A transparent material has been added so that the trigger area is visible in play mode.
D. Click the Edit Viverse Extension button.
A. In the VIVERSE extension, select the TriggerAndAction plugin for the Select plugins dropdown.
B. Add a Trigger and select EntitySubscribeTriggerEnter.
C. Add local-player to the tags to filter field.
D. Add an Action and select NotificationCenterPublish.
E. Create a unique name for the notification and add it to the notification name to publish field. In this example, the AddForce name is added.
Create the 3D object that the physics force will be applied to
A. Create a new 3D object.
B. Add a Collision component.
C. Add a Rigidbody component.
D. Set the Collision Type to Dynamic.
E. Click the Edit Viverse Extension button.
A. In the VIVERSE extension, select the TriggerAndAction plugin for the Select plugins dropdown.
B. Add a Trigger and select NotificationCenterSubscribe.
C. The same text that was added to the notification name to publish needs to be added to the notification name to subscribe.
D. Add an Action and select EntityRigidbodyAddForceInPhysics.
E. In the X Force, Y Force and Z Force fields, add values for the amount of force to apply in each direction.
