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"

Collision for procedural mesh generation

Hello all!

I use this link, and this link for making collision for generation meshes. I try include Physic Simulation and after that my mesh flying into the floor and remove from level. If i hadn't it , my character can jump on it and stoping.

Code which make mesh:

 PrimaryActorTick.bCanEverTick = true;
     Mesh = CreateDefaultSubobject<UCustomProceduralMeshComponent>(TEXT("ProceduralCube"));
     // Generate a cube
     TArray<FCustomProceduralMeshTriangle> triangles;
     GenerateCube(100.f, triangles);
 //    RootComponent = Mesh;

How i can include physic simulation and get correct work?

P.S.: I use MacOS.

Thanks for help!

UProceduralMeshComponent::CreateMeshSection(int32 SectionIndex, const TArray& Vertices, const TArray& Triangles, const TArray& Normals, const TArray& UV0, const TArray& VertexColors, const TArray& Tangents, bool bCreateCollision);

When you're building the mesh, make sure to set the bCreateCollision flag..set the collision channel response as you require and it should work fine.

In my case, when using UE 4.17.1 and procedural meshes, the collision only worked in preview mode, but in launch mode, they would not work even with the above suggested flag set to true. I had to add the following line after setting up mesh data:

 // Activates building collision data
