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"

Why a rolling ball jumps when cross boarders of landscape components? How to fix this?

This is very easy to reproduce. 1. Create a rolling template project and delete everything except the ball, lights and the player start. 2. Create a flat landscape filling the world. 3. Play and start rolling the ball.

If the ball gets enough speed, you will see a very high jumping when the ball cross the boarder of landscape components. It's easier to see the jumping location with the "landscape visualizers" set to "Layer Usage". Components boarders are shown as black lines in this mode.

We are developing a golf game. Our golf courses are created using landscape. So these "collision gaps" are causing very serious problems when golf ball rolls on green. Is there anyway we can avoid this problem?

Unfortunately, at this time we are not aware of any work around for this issue. We apologize for any inconvenience this may cause, but the rolling ball template is meant to be a template or to simply showcase how to create a project with a rolling ball theme.

Is there any news for that issue ? I want to use a physics simulated sphere on a landscape and I have exactly the same problem. I can't combine that two basic features and it's annoying.
