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"

How can I create a trigger box orActor that on collision updates a score sent to the HUD?

Hi, Ive been working on a VR version of the playground game 4 square and its going fine but i have a question. How can I create either an actor or trigger box that checks how many times an acor has collided with it the object in this case is the ball (Static Mesh Actor with collision) so I want to check if it has has colided with the trigger box or actor greater than 2 times then i want a counter on the HUD to go up by 1 However i also have an actor nammed destroy that destroys the ball when it collides with it then respawns it and so if the ball bounces in the trigger box or actor twice i want the counter to stay at its current value but if the ball has not bounced in any squares to reset the counteralt text
