Cross Fading

Cross Fading

In this article, we explain cross fading, provide the different techniques to create this effect, situations for which this can be useful and how to cross fade Doodly provided assets.

What is cross fading?

A cross fade is when two imported images provide the appearance of one fading out while the other is fading into the canvas.

Cross Fading Situations

• Custom Scene Transitions: Using the None Transition we can create our own custom scene transitions Watch the SoloBoss Scene Transitions video tutorial

• Asset Transfer: Transitioning from one asset to another. There are two items to watch out for when attempting this type of transition.
  1. Doodly provided assets draw the outline first prior to fading.
  2. Fully covering the initial asset during the transfer.
  
  Note: Read below under the Doodly Asset Transition section for more information on how to get around this issue.


• Creating Animation: Using a cross fade we can provide the appearance of animation. Read the Keyframing section below.

Custom Scene Transitions

There are several methods for cross fading full transitions.

• Exporting a full scene and using that as a background image in a new scene with the None transition, then fading another imported background image asset on top of it.


• Disabling Erase Mode then fading a full background scene on top of the other image within the same scene.


• Disabling Erase Mode, exporting a full scene screenshot and using that as canvas cover image on the next scene using the None Transitions and then covering that image asset with another asset while choosing the fade option.

Doodly Asset Transition

The Issue: Doodly draws the outline before it fades the asset into the canvas.
The Solution: Read Intermediate Skill Level Doodly Tutorial #29: Rapidly Export Multiple Multiple Assets.

• Export the Asset that is desired to cover the other asset. Ensure the background is with it and then screenshot that as a full screen view video.


• Import that image back in with the background. Having the background is important because we need the fading effect to cover the initial asset already on the canvas and the background will do this without it appearing that we are changing anything.


• Import the background screenshot into Doodly and onto the canvas.


• If you are using a 1920px X 1080px canvas, set the asset settings are set to the coordinates and width and height to:
  X=960
  Y=540
  Width=1920
  Height=1080

Note: If you are reading this and don’t understand why you cannot set the width and height separately, please read my Beginner Skill Level Doodly Tutorial #8: Working with Images

Key Framing

This is the act of placing one image after another for the appearance of animation.
