In Unit 6(A) Lesson 13 Bubble 8, there is a function PioneerApp that is called, but not defined. I’m assuming the definition is somehow hidden from the code students can see. I have a student who would like to use the assistive technology from this bubble in his Innovation Project, but we don’t know how to define it. Can anyone help?!

Hi @shannon_spisak,

Hmmm…I am pretty sure _PioneerApp_ is a way to point to the object that is the app. I don’t think we can see that and that it is why it was done for us. I tried to use “this.isClicked()” but that didn’t work.

I did recreate the app so it works by just checking to see if the x & y position of the pointer is within 30 pixels or so of the of the x & y position of the first image and if it is, then using setScreen to open the right screen. Would probably need to play with my numbers but I was able to open the Victoria screen when the pointer was under the Victoria image and I clapped but not when the pointer was in the starting position and I clapped (if that makes sense). FYI - when I ran the app with the accelerometer, the pointer goes behind the buttons. I didn’t play with the order of the app elements but that should fix it. [Here is my app](https://studio.code.org/projects/applab/qx5NXGo71OcGKr9YtFBj-q5xaJcz8F3pAQd_YqY4FXQ) **without the accelerometer code** since students should be working to figure that out. But, teachers can find that code in the exemplar.

If others have ideas, please share!

Hope that helps
