Camera shake

Hey Patrick,

You’re very close! Since the camera object’s position/rotation will often get modified by other components (such as World Tracking or Gyroscope), it’s better to display the result of the camera and then modify the display so they don’t conflict.

The fastest way to do this would be to go into your Objects panel: Add New > Billboard. This will create a new billboard to display a texture. 

Then, to display your Camera result: in the Inspector panel of your billboard, click “BaseTex”, then select “Camera Output”.

Since billboards covers the screen using an Aligner, in your script you want to access that instead of the SceneObject component.

// @input Component.SpriteAligner toShake

Then instead of modifying the SceneObject’s transform, you can modify the binding point of the aligner

script.toShake.bindingPoint = new vec2(newX, newY);

So your final script will look something like:

//shake.js

// Event: Frame Updated/tap/react


//adding for customisation

// @input float speed = 4

// @input float amount = 4

// @input Component.SpriteAligner toShake


var currentPos = script.toShake.getTransform().getLocalPosition();

script.yPos = currentPos.y

script.ZPos = currentPos.z


var newX = Math.sin(getTime() * script.speed) * script.amount;

var newY = script.yPos;

var newZ = script.ZPos;


//wrap in function for future calling

//function shakeObject(){

script.toShake.bindingPoint = new vec2(newX, newY);

//}

Using a speed of 40, and an amount of .10 I was able to get:

Can't wait to see what you come up with!

Hey Patrick,  Aww, Sorry about missing the deadline :( I went ahead and answered it the other post as well. I hope both of these can come handy in the future! Please let us know what cool stuff you make :)

Hi Bram, 

Hmm, what event are you setting the script to? The shake occurs because the billboard is displaced every frame. If it's only happening once, try setting the script to "Frame Updated". 

If you're still having issues, would you mind showing us the script and how your project is set up (picture of the Object and Inspector panel) so we can take a look?

Thanks!

Jon
