Hi, everyone. I'm new to houdini and i find the structure of the program something beautiful!
I've done the stikies animation tutorial http://www.sidefx.com/images/stories/tutorials/stickies/stickies_animation_tutorial.pdf [sidefx.com] and need to change the way the stickes moves randomly.
The point is that i want to move the stickies only when they change color. One by one.
Right now they change alls at the same time and it's not what i want.
I've done this expression
if(chf(“../pointColor/diffb”, $F - 1)==ch(“../pointColor/diffb”),$F,0)
in the seed attribute of the sort node, but take the change in a way i don't understand …
Anyone can help?
Thanks,
Marco

EDIT: i've discovered that the jitter node works in relation to the number of the point's array. It make the change in rotation and blend just when the point's number change. So what i need is to change the point number when it changhe color ………. it's right? …….. and how?!

EDIT 2: well … i can't solve the problem that way. But i think i can do in another one: creating 2 grids one for the standard color stickies, and this one never change it's rotation and blend. The other one whit the stickies that has a color different form the standard one. Simply use the alpha to hide the ones that i don't need in the groups.
I'll give a try in this week …
If anyone have a better solution i like to know it … just to learn some more
