Moving Pictures

I managed to kill 2 birds with one stone today and built a quick little demo that both demonstrates some motion paths in SL2 (which I wanted to do on the blog this week) and completes this week’s ELH Challenge!

This week’s challenge was to create create some pictograms for a specific industry or topic.  I am about to embark on a project that will have lots of images of kids, so that was my inspiration.

Creating the characters

All of these characters and their accessories were created in SL2 using the built in shapes.  I think the components are pretty easy to see, but feel free to download and dissect the file if you are unsure about how a shape was created.

Adding motion paths

Each character or their object moves when the character clicked. Here’s how each motion was created (from left to right):

2014-10-08_15-57-05Character 1 – The truck zooms away from the boy on one click, and then back to him on the next. Each motion is it’s own motion path. The first path is freeform, the second is a simple line. I changed the state of the truck image so that it would “point” in the direction it was moving. In order to trigger the correct motion path on a click, I used a T/F variable. It is toggled each time a motion path completes.

Character 2 – The doll moves between the arms of the girl. This was accomplished just like with character 1, but arc motion paths were used for both directions.

Character 3 – Her arm moves along a small circle path each time you click.

Character 4 – The ball is thrown up in the air… then falls back down to his hand. This is 2 connected motions, each a simple line. The trick is that I used a relative start point for the second path so it would be one smooth motion. (Relative start points were also used for characters 1 & 2).

Character 5 – Her books opens and glasses appear. This is just a simple state change!

The new motion paths in SL2 really open up a world of possibilities – this is just scratching the surface. If you are unsure where to start, you can check out this blog post by Mike Enders or some of these videos from Arlyn Asch. There is also a great practice activity in the community tutorials.

Most of all, have fun!
