Unit 3 Lesson 13 Example Animation Scene Bubble 2 or 3

[e201603892]

In Lesson 13, there is an example animation on bubble 2 and 3.

Code.org

The text in the lesson scrolls up the page with the Alien, we cannot see the code to see how this is working.
How is the text scrolling with the 2nd alien while the 1st alien wiggles and that text stays still. I would really love to be able to see this code.

Here’s a link to a previous response to this same question on the forum.

Code for U3L13 page 3

@colglazierj, I’m guessing it wasn’t done with javascript, but rather with variables. I’ll refer to the vertically scrolling text, (but a similar concept would explain the jittery text as well). If instead of specifying a precise y value for the text, you were to set the y value of the text to be equal to a variable (ylocation), you could then update the value of the ylocation variable inside the draw loop … (ylocation = ylocation -1); This would then cause the text to move vertically across …

Let us know if you still have questions after looking at it.

Thank you for your response, I am still not sure how to set this up. I have tried to create a variable, but am unsure how to then connect it to the text string, so I am unable to follow these instructions.

Here’s a link to a project I made that has a similar effect.
