Battling with a script to create specified number of color entries in a 2d ramp

[Robert Bateman]

You are missing a } at the end. You also seem to be adding ..... ?
setAttr ("rampSpecial"+".colorEntryList["+$i+"]"+".position" + $d + );

\edit
Personally I don't much care for the style of

for () {
}

You'll have less problems of this sort using:

for ()
{
}

just my 2cents...


\p.s.

this might be a nice thing to do:

setAttr -size 300 ("rampSpecial"+".colorEntryList);

and in addition, not sure what you are doing with $d? Should be 2 variables perhaps?


float $d = 1/300;
for ($d = 0; $d<1; $d++) {

Hey Robert,
Thanks for the reply and the helpful tips. I've had another attempt at the script after your post and doing some more reading.

setAttr ("rampSpecial"+".colorEntryList["+$i+"]"+".position" + $d +);
Yeah over here I was trying to make the "colorEntryList" create more entries counting up in integers
to the specified maximum value of 300. And then I wanted each of these new entries to be evenly spaced along the ramp, so the final result would be 300 colors on a ramp with 299 equal spaces between each color. But as you can tell I failed :blush:

With $d I was trying to divide 1 by 300, to give me a float value for the spacings between the colors on the ramp. I then wanted to add this float value to each respective colorEntry's position to space out the 300 colors evenly. I know now that I was supposed to convert the numbers to floats to give me a float output and also divide by 299 instead...float $d = (float (1) /float (299));

Also I tried this like you said after creating a node called rampSpecial..
setAttr -size 300 ("rampSpecial"+".colorEntryList");
Maya ran that line fine with no complaints but it didn't create 300 color entries. The ramp remained remains the same with it's default 3 inputs.

I thought I should start with something simpler.. making a ramp with 6 colors spaced randomly and then trying to space these color entries evenly along the ramp into 5 equal divisions using a mel script.
I know the steps would be:
-list each color entry,
-for each consecutive entry add 0.2 to the position value.

so it gives me a result like ..

"rampSpecial.colorEntryList[0].position" 0;
"rampSpecial.colorEntryList[1].position" 0.2;
"rampSpecial.colorEntryList[2].position" 0.4;
"rampSpecial.colorEntryList[3].position" 0.6;
"rampSpecial.colorEntryList[4].position" 0.8;
"rampSpecial.colorEntryList[5].position" 1;

I know that using
int &i;
for ($i = 0; $i<6; $i++) {
}
creates a variable $i that counts up.


and that this bit of script
float $c = (float (1) /float (5));

{
}
would give me an output of 0.2 , but in the end I would need to ++ add this value to each consecutive colorEntry's position. How do I do this? :cry:


Any further help would be greatly appreciated :bowdown:
