  hello, i have 2 files - main.nim and objects.nim main.nim:

  
  import libs/csfml/csfml
  import libs/opengl/opengl
  import objects
  
  var window = newRenderWindow(videoMode(500, 500), "OpenGL")
  window.verticalSyncEnabled = true
  
  opengl.loadExtensions()
  
  var event: Event
  
  while window.open:
    while window.pollEvent(event):
      case event.kind
        of EventType.Resized:
          glViewport(0, 0, event.size.width, event.size.height)
        of EventType.Closed:
          window.close()
        else: discard
    
    window.clear Black
    glRotatef(1,0,0,1)
    
    var a:object3d;
    object3d.draw
    
    window.display()
  
  window.destroy()
  
  Run

  objects.nim:

  
  import libs/opengl/opengl
  type
    object3d = object
  
  proc draw(this: object3d) =
    glBegin GL_TRIANGLES; block:
      glColor3f(0.0, 1.0, 0.0); glVertex2f(-1.0,  1.0)
      glColor3f(1.0, 0.5, 0.0); glVertex2f( 1.0,  0.0)
      glColor3f(0.0, 0.5, 1.0); glVertex2f( 0.0, -1.0)
    glEnd()
      
  Run

  and this code does not work. compiler writes: main.nim(24, 9) Error: undeclared identifier: 'object3d' but why? i used import -

   objects
  Run

  . everything must work, import dirrective adds code from objects.nim to main.nim and everything is should be compiled. please help me, i really dont know, why my code does not want to work

  Have you considered reading the fine tutorial?

  https://nim-lang.org/docs/tut1.html

  As you learn, in Nim like in other languages like Modula or Oberon public symbols in modules have to be marked with asteriks, so try something like

  type
    object3d* = object
  Run

  I solved the problem by writing

   objects
  Run

  I solved the problem by writing include objects

  Sure, you can do that, but it is not very smart. Why do you ask here when you are not willing to learn something?

  I created myself some future problems by writing include objects

  FTFY
