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 get box collision to react to launced (impulsed) actor

I have a box collision set up to toggle a light, everything works fine when i carry the actor to the box, but when i launch the actor with an impulse the event does not trigger at all, (i am working in blueprints if that matters) if anyone knows a solution or workaround that would be greatly appreciated!

Merry christmas :D

Showing what you have will go a longer way towards a helpful response than a basic explanation. No clue how you're doing the detection.

Thanks for pointing that out, new to the forum and UE4 in general, are these illuminationg enough?

If the velocity is quite high, the period of time when the cube is within the Collision Box may actually fall between ticks. I suggest finding the Use CCD checkbox (both in the wall and in the launched cubes) and tick it. Thus the launched cube will (well, should) always stop upon hitting the wall and actually be within the Collision Box.

Unfortunately, the Continuous Collision Detection (CCD) only works with blocking, not overlapping, so if there's something to block the projectile, like in your case, that's fine; but if the Collision Box is on its own, that won't probably work.
