Painting Plugin Help

[renderiza]

Hi,

I want to create a plugin that will feel like I am painting. Have couple ideas but want to start by copying a 2D or 3D geometry and by pressing & holding a key it will keep pasting the geometry so that if I move the mouse it will feel like a Photoshop brush.

Javascript Code that will be sended to Ruby with other code using params;

if (keyIsDown[SPACE]) {		
paint = 1  			
}
if (keyIsDown[SPACE] == false) {
paint = 0 ;
}

Here is Ruby Script ;

if params['paint'].to_i == 1  ;	  
  Sketchup.send_action(CMD_PASTE) ; 
end

The thing is that when I click Spacebar the object paste itself but problem is I need to click with mouse to put it down and this disrupt the flow of things. I want to Press spacebar and object automatically paste itself down without clicking mouse.

Any Suggestions?

Yeah, you need to specify in your code where to put the instance. You would do that with a pickhelper. Is this plugin written inside a SketchUp Tool class? You will need to do it as a tool to track the cursor position, so you can then insert the instance at the cursor position.

The description is a bit lacking. Not 100% sure what you're code is doing, but when you say "I need to click with mouse to put it down and this disrupt the flow of things." I then take it you used Model.place_component? In order to just insert a component you use entities.add_instance.

... ah ... you trigger SketchUp's Copy and Paste commands. What you probably want to do instead is use a variable to store the reference to the instance or definition you want to "copy" - then you can use entities.add_instance.

Didier Bur has done several Component Spray plugins. Look at what he has done.

Hi, thanks for the replays

Chris Fullmer this might be the answer but I need to study how to apply this little more. If I am not mistaken this will get the coordinates of the object that is referenced under the mouse.

So somehow I need to make a variable that gets the values of does coordinates so I can do what Thomthom said... entities.add_instance

Dan Rathbun the Compo Spray has the same issue I am having and that is that in other to keep dropping coponent one has to keep clicking the left mouse click.

It would be ideal to click & hold and components constantly keep dropping.

I already have web dialog updating 15 frame a second all I need is a way to get rid of the multiple clicks and I am golden.

Note: Still lack a lot of knowledge in creating geometry with code but little by little I will learn...thank you guys really appreciate it.

Here is a really quick tool that shows how to "paint" with components. I forget how the "flags" work, but it looks like you get a flag of 1 if the mouse button is down. Isn't there a list somewhere of the flags?

I wrote this quickly as a test code. I run my code snippets like this in a multi-line code editor in SU (Like Jims, or Alex Schreyers, or Aerilius).

You must have a component selected before running the snippet. Then just hold the left mouse button down and move the mouse and it will paint the selected instance.

class Cltool


def activate
@@sel = Sketchup.active_model.selection[0]
@@ents = Sketchup.active_model.active_entities
end

def onMouseMove(flags,x,y,view)
  ip1 = view.inputpoint x,y
  point = ip1.position
  if flags == 1
    add_object(point)
  end
end

def add_object(point)
t = Geom;;Transformation.new(point)
@@ents.add_instance(@@sel.definition,t)
end


end
Sketchup.active_model.select_tool Cltool.new

Christ Fullmer you are a genius!!!

This transform SketchUp into the best painting application in my opinion...I will see If I can expand this & add new features to make it even better.

I am so excited!...again thanks!
