Search help

  • Simple searches use one or more words. Separate the words with spaces (cat dog) to search cat,dog or both. Separate the words with plus signs (cat +dog) to search for items that may contain cat but must contain dog.
  • You can further refine your search on the search results page, where you can search by keywords, author, topic. These can be combined with each other. Examples
    • cat dog --matches anything with cat,dog or both
    • cat +dog --searches for cat +dog where dog is a mandatory term
    • cat -dog -- searches for cat excluding any result containing dog
    • [cats] —will restrict your search to results with topic named "cats"
    • [cats] [dogs] —will restrict your search to results with both topics, "cats", and "dogs"

Testing AR - Do I have to build every time?

Hi!

I'll be developing an AR app for mobile devices that support ARKit / ARCore. My question is, every time I wish to test a change or toubleshoot something, do I have to re-build the whole project and re-deploy it on my device? Is there a possibility, to somehow feed the data from the mobile device back into the engine and just rapidly prototype things, without the massive downtime each time I wish to test a change?

Thanks!

Yes, I also would like to know about possible ways to emulate AR on PC. Currently, I do a small change and compiling it for 30 min to preview this change and then I move on again. It takes a long time in production.

Howdy Hi!!!!

That would depend on what you are testing, and if you are changing code. If your changing blueprints, or C++ your going to need to rebuild. If your only testing, how the "data" that you refer too is impacting the code, then only that should need to be changed. If your testing changes to a 3rd Party Library, only the library would need to be changed, if you are loading the library itself, and not integrating it into the "game" itself.

But without a clear definition of the "data" that you reference, it's hard to give a more clear answer. Bottom line is, whatever your changing, will need to be rebuilt.
