Change ImageTarget during runtime

asked Apr 11 by guilhermeflex (610 points)
Hello! I want to download a few images from my asset bundle and use them as target for Image Track.

Can I download the imagem directly into StreamingAssets and change the image tracking reference during runtime?

Thank you!

Of course. Try the sample.

Which sample? I couldn't find a sample specific for this feature.

The samples load images from streaming assets, aren't they what you looking for?

Noup. I want to make a project with one target and build for Android/iOS. AFTER I built, I want to use Unity's asset bundle to add more targets, with user downloading images from their phone and setting these new images as targets.

Not in Unity scene, doing that in the live app downloaded from the store

Not sure about what you are trying to do. But let me explain in another way.
The samples show how to create a target from memory buffer or image file. If you can find a way to create an image file (jpg or png) or get image byte array (byte []), then you can do it.
I believe getting image file or byte array will not be a blocking issue, at least they are not something AR related.

That's sort of what I wanted!
So, EasyAR documentation doesn't have a tutorial on how to achive what you explained, right?

At least I couldn't find.

The idea is to create new targets during runtime by downloading images on my smartphone.

Let me know if you got it working! I'm doing the same thing, loading targets from a downloaded image, i got it working in unity editor, but i had no luck with it on android build, also adding file:// at the beginning of the loading path of the imagetarget.
