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"

Uncaught typeError : cannot read property 'size' of null


I have packaged and uploaded my first UR4 creation in HTML5 to my server and the game works perfectly on Windows 7 64bit inside Chrome 32 bit and 64 bit. However, if I try to play it on a Windows 7 32-bit, I get the "Uncaught typeError : cannot read property 'size' of null" error inside the browser window. Is there any setting that I could change in my build process that will fix this?

Here is the link to the game. I extended on the basic online lesson on how to create an infinite runner and learnt a ton of stuff about programming UR4 with blueprints, but as you can see, I still have A LOT to learn! To run the game, click on the orange button at the bottom (Démarre l'application). (http://www.educatom.com/robosprint)

Thanks for any help on this! Tom
