Doodly Advanced Tutorial

Slide In Reveal Method

Advanced Tutorial #26

Slide In Reveal

We’ve all seen the exit animation for transitioning to another scene where the objects seamlessly fly off the canvas. This article teaches you how to create that same effect when introducing your assets.

Note: This effect works within limitations of Doodly. Doodly natively supports only two options for this effect. Natively we can do just the first asset or all assets at once for the desired effect introduced to the scene using a whiteboard or solid color background as long as there are not other stationary assets already on the canvas. We can use other advanced techniques to provide an individual swipe in effect for each asset, if desired.

Prerequisites


Grid Usage

Requirements


Green Screen and Masking

For a single scene individual asset slide in effect.

Preparation

We are using the Pan and Zoom for this effect. Pan and zoom does not have a grid, snapping or any other type of aligning tools available to us so we need to manually align everything. Use the SoloBoss asset alignment tool as a background image for the custom canvas to assist with this task.

All the Doodly provided assets are Scalable Vector Graphics (SVG). They can be resized without losing quality of the image. This trick makes use of the SVG architecture and the unlock start option in the Doodly Pan and Zoom feature.

There are 2 main issues that are addressed with creating this effect.

  1. In order to get the panning option, we must lower the size of the viewable canvas inside the pan and zoom. This means resizing the the assets within that canvas.

  2. When we increase the viewable size of the canvas back to full screen, the assets will appear much smaller so we must resize them and move them into the correct location. We use the grid and snap to grid feature to solve this issue.

Creating the Fly-In Swiping Action

This requires 2 scenes.
First Scene: Asset Movement

Second Scene: Resizing the Asset

Advanced Technique for Individual Slides

We can create a single scene where all the assets individually slide out by using green screen techniques and matching them up in a separate video editor.

Frequently Asked Questions

Doodly only offers limited native support for this type of entrance. You can apply the entrance to either the very first item or all items simultaneously. This native method also requires a plain whiteboard or a solid color background, and it will not work if you already have stationary items on your screen.

The pan and zoom tool does not include a grid or snapping tools to help you line things up. To solve this problem, you should set a custom canvas and use an alignment tool as your background image. This background guide will help you manually place your items in the exact right spots before you finalize the scene.

You need to unlock the start option in the pan and zoom settings and reduce the viewing area to about half of the total width and height. You then place your starting and ending points based on the direction you want the item to travel from. Making the duration of this camera movement longer will result in a slower and smoother entrance for your item.

Building this animation requires two separate scenes. The first scene handles the actual movement of the item using a custom canvas and camera panning. The second scene returns the camera to full screen and requires you to resize the item and adjust its position so that it matches the final placement perfectly.

Yes, but you will need to use an external video editor to achieve this advanced technique. You must export a separate video for each individual item using a green screen background. Once you import these separate videos into your external editor, you can use a chroma key tool to remove the green background and layer them together to appear sequentially.
