hi,

  1. how can i scale my object using the "WORLD" coordinate system  in python ?
    i tested many many possibilities, but no success

here an example of what i'm trying to do,

  
#transform a 45° rotated cube into lozenge by making 200% scale on the X-axis    
obj = doc.GetActiveObject()
obj_Mat = obj.GetMg()         #my cube matrix
sc_vec = c4d.Vector(2,1,1)
sc_mat = c4d.utils.MatrixScale(sc_vec)
myObj.SetMg(obj_Mat.GetNormalized()*sc_mat)
  
##result : local x scaling   
  1. how to change the size of my " Primitive" object without changing it's scale ?
  2. is it possible to add some informations to the HUD using python?

thanks in advance

To do that you can access the object description. For example drag the cube's Size.x to the edittext in the console, you'll get:

Cube[c4d.PRIM_CUBE_LEN,c4d.VECTOR_X]

Now you can set the Size.x:

Cube[c4d.PRIM_CUBE_LEN,c4d.VECTOR_X] *= 2

By HUD do you main GUI ? What kind of information do you want to ouput ?

let me be more precise, i agree with you, but i'm looking for something more 'general'. while this formula will work only with cubes ... i don't know if this is possible, thats why i'm asking ;)

i mean tha same thing when you drag&drop any properties into the viewport, or by doing right click>> Add to the HUD.
i want to display some integer values, or custom text.
 
thank you again!
cheers

For all primitive objects you can scale them with ID_BASEOBJECT_REL_SCALE:

Cube[c4d.ID_BASEOBJECT_REL_SCALE,c4d.VECTOR_X] = 2.0

I'm afraid, this isn't possible to do in Python.

hmm ... ok!

..which means that is possible in c++?
thank you!
Best.

In C++ neither.

Concerning to what littledevil said, you may use the DrawHelper plugin to enhance your skills with
the BaseDraw class. 😉 It is similiar to the PyGenerator Object, but instead of generating Objects,
it enables you to do drawings into the Viewport.

Available gloabl variables are:

raw:       the ObjectData Instance of the DrawHelper object
op:        the BaseObject Instance (like in a PyGenerator)
drawpass:  the Drawpass
bd:        the BaseDraw Instance
bh:        the BaseDrawHelper Instance

Note: Take care that you don't have important scenes opened. I must admit that I have noticed several crashes when closing Cinema 4D and the DrawHelper object is present in your scene.

Yes, it is possible. By first drawing text into a bitmap with the GeClipMap class. Then drawing this bitmap with DrawTexture() into a view BaseDraw.

i'll test this, thnx 😄

actually, another problem disturbing me now, in fact i'm trying to make a plugin tool, and i'm trying to understand how to get some values (combobox value, and number) from the subDialog interface.

i tried to get them from the 'data' container (cf. mouseinput, draw, etc..)  but it seems empty :S

here an example that i did yesterday :

import c4d, os
  
IDP = 1000001
  
  
class myToolDialog(c4d.gui.SubDialog) :
	
	ID_COMBO	 = 10002
	ID_NBR	   = 10003
		
	def CreateLayout(self) :
  
		self.GroupBegin(10000, c4d.BFH_FIT, 3, 1)
		self.GroupBorderSpace(10, 10, 10, 10)
		
		self.AddStaticText(10001, c4d.BFH_LEFT,0,0," Value  ", c4d.BORDER_NONE)
		self.AddComboBox(self.ID_COMBO, c4d.BFH_SCALE | c4d.BFH_FIT, 0, 0, False)
		self.AddChild(self.ID_COMBO, 200, " Red ")
		self.AddChild(self.ID_COMBO, 201, " Blue ")
		self.AddEditNumberArrows(self.ID_NBR, c4d.BFH_FIT)
		
		self.GroupEnd()
		
  
		return True
  
  
  
	def InitValues(self) :
		self.SetLong(self.ID_COMBO, 200)
		self.SetReal(self.ID_NBR, 10)
		return True
  
  
		
		
		
class MyToolPlugin(c4d.plugins.ToolData) :
  
  
	def MouseInput(self, doc, data, bd, win, msg) :
		value   = self.dialog.GetLong(10002)
		nbr	 = self.dialog.GetReal(10003)
		
		#print 'On Click >>> Value : ', value, ' >>> Nbr : ', nbr
		return True
  
		
	def Draw(self, doc, data, bd, bh, bt, flags) :
	
		value = self.dialog.GetLong(10002)
		nbr	 = self.dialog.GetReal(10003) 
		print 'Draw >>> Value : ', value, ' >>> Nbr : ', nbr
		
		if value == 200:
			color = c4d.Vector(1,0,0)
		else:
			color = c4d.Vector(0,0,1)
			
		bd.SetMatrix_Matrix(None, c4d.Matrix())		
		bd.DrawSphere( c4d.Vector(0,0,0), c4d.Vector(nbr, nbr, nbr), color, 0 )
		
		return c4d.DRAWRESULT_OK
  
	
	
	def AllocSubDialog(self, bc) :
		self.dialog = myToolDialog()
		return self.dialog		
  
  
if __name__ =='__main__': 
	mypath, myfn = os.path.split(__file__)
	c4d.plugins.RegisterToolPlugin(id=IDP, str="Test", info=2,icon=None, help="TEst test", dat = MyToolPlugin())

Please have a look at Liquid Painter example to see how this could be done.

I'm not very good at dictionaries( because I don't use them very often). And I found the code in the LP plugin quite convoluted and hard to follow.
It was quite a frustrating experience for me.

I re-wrote my SplineDraw tool using a dictionary in a similar manner. And I think it's a lot simpler and easier to understand how it works the way I wrote it.
