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"

Prevent Interaction through actors

I was following this tutorial on how to create a reliable interaction system that allows the player to choose which object to interact with based on vectors (https://www.youtube.com/watch?v=JDrdfCyujJE). His system works perfectly fine and it provided all the utility that I needed from an interaction system. However, my biggest issue is that the player can still interact with the objects even if there's a wall between the object and the player. How do you make it so that the player cannot interact with the object if there's a 'solid actor' between the player and the object? Is there a setting that I need to enable, like how there's one for collision? Side Note: If we imagine a scenario where there's a box and in front of it there's a pillar, the player can still interact with the box if he/she look next to the pillar and see the box while standing in front of it (while the box is covered and on the other side). So I want it to be based off the mesh of the 'solid object' rather than based off of a trigger box or a location value.
