I placed the entities in redist/custom_storys/entities/walls/...
And also in redist/entities/walls/....
But as title says, there are not available in the Editor.
Can anyone tell me why?
You can't simply copy the files from static_objects into the entities folder, if that's what you did. You need to import the .dae files into the Model Editor and add bodies and customize additional properties of the entity and save it as an .ent file.
Try moving all the files up one level. If you have them in too many subdirectories the level editor might not find them. Also try hitting the refresh button and/or restarting the level editor.
Ok now I placed it just in the redist/entities/... folder and made there a new called walls and put them files into it.
Now it works, thank you very much.
