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"

Thin walls being penetrated by projectiles

Hi guys,

I have a thin wall, which is a default cube scaled by 0.1 (10 cm) as it's thickness (so that it looks like wall). Wall is set as BlockAll. Projectile is a static mesh with capsule, and the capsule defines the collision (and is set to block all). Projectile component is also there. While I shoot into the wall, the bullets sometimes penetrate it. Here is a video of it:


What should I do?

In the projectile's properties, under the Collision category (also check Show Advanced Properties), check "Use CCD" (CCD = continuous collision detection).

PS. In C++ it would be ProjectileCollisionComponent->BodyInstance.bUseCCD = true;.

Do you know by any chance how to change the UseCCD bool with blueprints?

sure. You can find it under Collision section in the component details.

Thanks. Would have never guessed that :)

Glad to help! You have to check "Answered" again though, it clears if you post a comment after checking it.
