Issue with curve()
Jan 23rd, 2009, 11:35am  
I've just started using Processing (and programming in general), so bear with me if I'm making silly mistakes.

I'm attempting to get the curve() function to work. I wrote the following code into my program to test the function out...

curve(142.5,90,165,65);

Unfortunately, I'm getting the following error: "The method curve(float,float,float,float,float,float,float,float) in the type PApplet is not applicable for the arguments (float,int,int,int)". I have no idea what that means. I've tried changing it to:

curve(142.5,90,155,75,165,65);

in the hopes that perhaps I just needed an extra set of points, but I received the same error. It's rather clear to me that I have no idea how this function actually works, and the reference page is of little help. If someone could provide some insight as to how to use this function, I would be rather grateful.

curve() needs either 8 or 12 variables, the references is rather clear on that imho.

Hope this helps.

Ah, I was under the impression that eight variable was simply an arbitrary number (that is to say, they could have easily used six or ten). Apologies for the silly mistake.

Thank you much for the help!

T.J., for your information, Java has no functions with variable number of arguments, so you have to provide the exact number of arguments shown by the reference.

Now, I lied... Since 1.5, Java can have functions with variable number of arguments, but Processing doesn't support that (yet), so the above is true in our context... Smiley
