Take a Picture and Add/Generate a Billboard

Hi Nicolas! This is definitely possible. First, we'll create a new camera and camera texture that will represent our photo taking. Then, we'll create a billboard that utilizes this camera's texture. We'll then show the billboard when the "photo is taken". And this is very similar to how the freeze camera textures work in the Fullscreen template. I'll walk through how to set this up. 

• Create a new camera. In the Objects panel: Add New -> Camera
• Set the new camera's input texture to Device Camera Texture
• Create a new camera texture from this camera. In the Resources panel: Add New -> From Camera -> select the newly created camera. You'll now have a texture in your Resources that represents the camera's feed.
• Create a new billboard. In the Objects panel: Add New -> Billboard
• Assign the billboard's texture to your newly created camera texture

Then, to take a photo, you need to create a simple script to turn off the camera (which freezes the camera texture) and turn on the billboard. Here's a quick script to do that which I bound to the tapped event so that when you take the screen, it takes the picture and shows the billboard. Note, this script assumes you've turned off the billboard (unchecked) in the objects panel. 

// -----JS CODE-----
// @input Component.Camera camera
// @input SceneObject billboard

script.camera.enabled = false;
script.billboard.enabled = true;

Hello Travis!

Wow! Thank you so much. I am going through this right now and am wondering what tapped event you are referring to. Are you referring to a tapped event inside of one the provided scripts in Interactive tap?

Also, when you're assigning the billboard's texture to your newly created camera texture, are you assigning it to the Orthographic camera set up with the billboard? Or are you using a sprite with your new camera?

This might also lead to the right direction. I am thinking that you want me to assign the script to the sprite within the Billboard setup. I just need clarification. :)

Also, I can't really seem to find a script that activates events when you take a picture with the camera. Is there a piece of script that I can set Events with taking pictures with the camera? 

For example, If the user takes picture then activate Billboard. The user is going to be using "Tapped" to trigger the Tapped Event the Character plays in the Interactive Play. I want to trigger the Billboard when the user takes a picture, not by tapping once on the screen because I need that function to play animation.

Hey Nick! I went ahead and created a sample project of this. You can download it here:

Hope that helps!

Travis - is there any way that I can lock the shape of the billboard? I need my snapshot billboard (which I've resized to a square using the aligner width and height) to line up on top of a graphic on the billboard behind it, but when switching devices in the preview it is making the snapshot billboard stretch (the shape is still filled, but it is a horizontal rectangle, for example, instead of the original square).
