Hello everyone, i have a question, i’ve created a blueprint based on custom class which extended from AActor, when i tried use raycast to get calss name, it doesnt see this object, so what should i do?

Hey man,

There are few possibilities for that.

  1. If i understand correctly, the raycast doesn’t find your object am i right ?
  2. if it’s that you need to check the collision channel you use for the raycast ie : ECC_Camera, ECC_Visibility, …
  3. You must check the response for that channel on the specific object you try to raycast.

see the documentation for more details

thanks for reply. Yes, you are right. Channel response is blockall, my raycast collision channel is ECC_Visibility

Do you use a simple line or a multiple or a sweep ? Also you mean that your object youre trying to raycast is set to block all on collision channnel property ?

Did you set set a breakpoint to see what the raycast caught ?

Check the FHitResult

Did you catch something ? if yes the Bhit within the FHitresult will be at 1.

ok, thanks man, i solved this problem. My blueprint consists of Skeletal Mesh, so i had to add box collider for collision. so I added this box and put collision type to BlockAll, and now it works.
