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 to know which direction a car is facing?

Hello guys, I am currently working on a car game project and I want to make it impossible for the player to go in the opposite direction the race is going, so he always has to go in the correct direction. Any ideas on how to implement this?

Hi,

you can make hidden indexed check points through your map on every corner (so actually it will be actors putted into array after creation), so when player come across one, write it in his custom player controller. Then in tick event in custom player controller BP check if player's car direction (you can get it with function called "GetRotation") are the same one as direction from player's car to next hidden checkpoint (actually it should be angle between 2 direction, if it's not more than 90%, then more likely player going in right direction.
