An Action That Toggles An Object's Collider On/Off
This guide provides instructions for setting up the EntityToggleCollision action. In the sample app, every time the avatar enters the green trigger area, a notification is sent to the wall and the collider on the wall is toggled on/off. The wall is green when the avatar can pass through and red when the avatar can not pass through.
Before the avatar enters the green trigger area, the wall is red and the avatar can not pass through it.
Once the avatar enters the green trigger area, the collider on the wall is toggled to be disabled. The wall is green and the avatar can pass through it.
In this example, a trigger is created and when the avatar enters the trigger area, an action sends a notification to toggle another object's collider on/off. 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. Add a 3D object to the scene.
B. The Collision component is not required for EntityToggleCollision action to work. The Collision component is required for the EntitySubscribeTriggerEnter trigger that will be used in this example.
