How to get MEL script to read multiple columns

[haggi]

I suppose the layout of your file looks like the following:


tx1 ty1 tz1 rx1 ry1 rz1
tx2 ty2 tz2 rx2 ry2 rz2
...


To read this it is much more conveniant to read one line at once with fgetline().

string $line = fgetline(fileID);
while($line)
{
string $array[];
tokenize " " $line $array; //I'm not sure about the syntax here
setAttr yourObject.translate (float)$array[0] (float)$array[1] (float)$array[2];
setAttr yourObject.rotate (float)$array[3] (float)$array[4] (float)$array[4];
$line = fgetline(fileID);
}


Or a bit shorter with python:


fh = open("file.txt", "r")
for line in fh:
tx, ty, tz, rx, ry, rz = map(float, line.split())
cmds.setAttr("yourObject.translate", tx, ty, tz)
cmds.setAttr("yourObject.rotate", rx, ry, rz)


Or even shorter with pymel:

fh = open("file.txt", "r")
yourObject = PyNode("yourObject")
for line in fh:
v = map(float, line.split())
yourObject.translate.set(v[:3])
yourObject.rotate.set(v[3:])


I didnt test this code so there are maybe some errors.

edit: Just saw that your file layout seems to be more like this:
rx
ry
rz
.....

So it may be a bit different. But the getline() is here useful too with the difference that it returns only one value.
The code above coule be modified this way:

while($line= fgetline(fileID))
{
string $array[];
$array[0] = $line;
// read the next 5 lines
for(int i = 0; i < 5; i++)
$array[size($array)] = fgetline(fileID);

tokenize " " $line $array; //I'm not sure about the syntax here
setAttr yourObject.translate (float)$array[0] (float)$array[1] (float)$array[2];
setAttr yourObject.rotate (float)$array[3] (float)$array[4] (float)$array[4];
}
