Code Problem - total beginner
1 Comment
Hi everybody,
I am a total beginner (wikitude and coder). I am working on my bachelor thesis - support deaf children to learn reading.
I only want a normal image tracking in connection with a video overlay.
So I took the wikitude example and tried to change the code.
e.g. for the adjectives I have 50 different images to track and want to play 50 different videos ( in connection with the correct image).
I need also a button which should repeat the video.
I made the wtc file. - and I tried to code. ( see below)
Is this correct, or how should the code looks like ?
Thank you so much!
Markus
