Beginner having troubles

Hi guys
string axis = "x";
MPoint point;
if (point.axis == 0)
{
}
Simplified version of some maya api code,but you get the idea :)
axis is the flag for the command and can be x,y or z.In this case it is set to x for demonstational purposes.
This is the problem point.axis
I can't do it like that,and i want if x is chosen to compare only x value of the point with some else.So how to do it?
thank you
Quote:Original post by TheMan22What's wrong with if (point.axis.x == 0)? What is "MPoint::axis"?

What does the local variable, "axis" have to do with anything?

MPoint does not have axis method.
axis is a variable and can get values x,y,or z.
MPoint has methods MPoint::x,MPoint::y and MPoint::z
So axis tells which one of those should be used,you understand now?

Quote:Original post by TheMan22Ah, I see. Then you'll want something like:

if(axis == "x" && point.x == 0){ // Whatever}else if(axis == "y" && point.y == 0){ // Whatever}else if(axis == "z" && point.z == 0){ // Whatever}Assuming C++, that is. Also note that string comparisons are case sensitive.

no other way to do this ?
I must use if statements?
In mel for example you do this :
polyCube -name "some" // means create a 3d cube called some
And you can do something like this :
string $name = " -name ";
eval("polyCube" + $name + "\"some\"");

string $name = " -name ";
eval("polyCube" + $name + "\"some\"");
