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"

Aligning CollisionBox and ArrowComponent to Mesh side

I've created an Actor called "FloorActor" to represent generated floor meshes in my level. The design is similar to "Endless runner" game in the tutorials, though my meshes are scaled randomly. I've also created a scale function inside the FloorActor class to handle scaling:

 /** Set floor mesh scale */
 void AFloorActor::SetMeshScale(float X, float Y, float Z)
     FloorMesh->SetWorldScale3D(FVector(X, Y, Z));

My GameMode blueprint handles creating the first floor under the DefaultSceneRoot and scaling the created floor randomly. I haven't created any generator for further floors as I don't know where to place them in my world: alt text

Am I able to attach and align a CollisionBox and Arrow Components as I am scaling the floor? The alignment should look like this: alt text

This is for my GameMode to know when my character enters a certain floor, thus creating a new floor ahead and destroying the passed floor.

Any help and even design suggestions are greatly appreciated.
