here’s the script :
http://pikilipita.free.fr/blender/piki-stalac.py
It’s a script which randomly creates several piles of boxes.
It’s not very usefull, but i made it as an exercise…
here’s the result :
And here’s a Yafray render :
I don’t think you should characterize it as ‘not very useful’. Fiddling with a few of the parameters would enable it to generate cities, molecules, pseudo-metaballs, treetrunks… and in conjunction with the build effect…
Don’t get boxed in by the boxes!

This could be the beginning of a nice greeble plugin!
Fligh is right, this script could very well be the beginning of a city script, like the one here. http://members.tripod.com/~DCieslak/util.html
Exactly !
My initial goal was to make a city gerenator.
But for the moment, i’ll try simpler things…
I’ve updated my script, it now has a Gui, and you can choose
a few values in the generator.
BUT , each time you hit the “generate” button, the value of
each button return to its start value.
AND i don’t want this toi happen…
How to make the buttons not to reset ?

Blender.Draw.Button("Exit", 1, 120,10,100,25, "Exit script")
The trick is to replace the Default values in the buttons by the value of the button (variable.val).
Martin
Oh yes, i understand !
Thanks
Oh no,
it didn’t worked
File “piki-stalac.py”, line 113, in gui
ttributeError: ‘int’ object has no attribute ‘val’
or
File “piki-stalac.py”, line 113, in gui
ttributeError: ‘float’ object has no attribute ‘val’
try initializing them at the start of the script.
pilex = Blender.Draw.Create(1)
piley = Blender.Draw.Create(1)
pilez = Blender.Draw.Create(1)
You need to use the Blender.Draw.Create function when you want to use a variable to store a button’s value.
Martin
Thanks a lot Theeth, it worked !
a few last questions :
-
what is the default value of a variable when you use it for the first time ?
Zero ? -
How, using script, can i delete one of my boxes ?
for example the one called :
ME:box1 OB:Mesh.001 -
And by the way,
i guess , ME is for mesh and OB for objet
but what is the difference between a mesh and an objet ?
is this difference only used in realtime engine ?
A variable is not initialised until you create it. Then, when you create it, it has the value you give it, so there is no initial value as is.
I don’t recal how to do that, but there must be a way.
The Object contains the data about the position, rotation and sizing of the object. The Mesh contains the data that is inside the object. If it is a mesh, that means that the Object data is linked with a Mesh data. You can also link Lamp data with Object data, Camera data with Object data, …
I hope that’s a bit clear.
