CreateEntity() failing

[williamvanhoecke]

Hello,
Does someone know why the ENT = CreateEntity(#PB_Any, MeshID(LIN), #PB_Material_None,0,0,0,-1,#Mask2) does not work in the below example code ?
Thanks in advance

Code: Select all

  #Mask1 = 1 << 0 ;binary 1
  #Mask2 = 1 << 1 ;binary 2 
  InitEngine3D()
  InitSprite()

  OpenWindow(0, 0, 0, 640, 480, "Line3D example", #PB_Window_SystemMenu | #PB_Window_ScreenCentered)
  OpenWindowedScreen(WindowID(0), 0, 0, 640, 480, 0, 0, 0)

  ; Light
  CreateLight(#PB_Any, RGB(25, 25, 180), -5, 10, 5, #PB_Light_Point)

  ; Camera
  CreateCamera(0, 0, 0, 100, 100)
  MoveCamera(0, 2, 1, 3, #PB_Absolute | #PB_Local)
  CameraLookAt(0, 0, 0, 0)

  ; Create the line and attach it to the scene
  OBJ = CreateNode(#PB_Any,0,0,0)
  LIN = CreateLine3D(#PB_Any, 0, 0, 0, RGB(255, 0, 0), 1, 1, 1, RGB(0, 0, 255))
  ENT = CreateEntity(#PB_Any, MeshID(LIN), #PB_Material_None,0,0,0,-1,#Mask2)
  AttachNodeObject(OBJ,EntityID(ENT))

  Repeat
    RenderWorld()
    FlipBuffers()
  Until WaitWindowEvent(1) = #PB_Event_CloseWindow

Hello, this work.
A line 3D is a mesh but work like an entity.

Code: Select all

  #Mask1 = 1 << 0 ;binary 1
  #Mask2 = 1 << 1 ;binary 2 
  InitEngine3D()
  InitSprite()

  OpenWindow(0, 0, 0, 640, 480, "Line3D example", #PB_Window_SystemMenu | #PB_Window_ScreenCentered)
  OpenWindowedScreen(WindowID(0), 0, 0, 640, 480, 0, 0, 0)

  ; Light
  CreateLight(#PB_Any, RGB(25, 25, 180), -5, 10, 5, #PB_Light_Point)

  ; Camera
  CreateCamera(0, 0, 0, 100, 100)
  MoveCamera(0, 2, 1, 3, #PB_Absolute | #PB_Local)
  CameraLookAt(0, 0, 0, 0)

  ; Create the line and attach it to the scene
  OBJ = CreateNode(#PB_Any,0,0,0)
  LIN = CreateLine3D(#PB_Any, 0, 0, 0, RGB(255, 0, 0), 1, 1, 1, RGB(0, 0, 255))
;   ENT = CreateEntity(#PB_Any, MeshID(LIN), #PB_Material_None,0,0,0,-1,#Mask2)
  AttachNodeObject(OBJ,MeshID(LIN))

  Repeat
    RenderWorld()
    FlipBuffers()
  Until WaitWindowEvent(1) = #PB_Event_CloseWindow

Thanks minimy
Confusing dough, helpfile clearly says a line3d is a mesh. So assumed that an Entity could be created from it.
I need the Entity because I need a visibility mask to NOT let it show on all cameras
The way you do it works, but .... I am losing the visibility mask and the line is shown on ALL cameras

Hello, can create a 'dummy' entity like in this example or can create vertex to make a mesh for use as line.

This example work. You can see line in camera 0 but not in camera 1
I hope this help.

Minimy,
I already found another way around, I simply used a cube entity to form a line.
But the explanation with the invisible Entity as container for some other visible entitys is usefull for another problem I have.
Thanks.
