# Less repetition and code?

Hi there! I’m pretty new to OF (2 weeks in) and still just getting the hang of things. I was practicing by creating a pattern of the letter W and have it rotate from the center to mouseX. The thing is, I found myself copying and pasting this over and over.

``````ofPushMatrix();
ofTranslate(50,50);
ofRotate(mouseX);
drawW(-40,-40,20,80);
ofPopMatrix();

ofPushMatrix();
ofTranslate(150,50);
ofRotate(mouseX);
drawW(-40,-40,20,80);
ofPopMatrix();

ofPushMatrix();
ofTranslate(250,50);
ofRotate(mouseX);
drawW(-40,-40,20,80);
ofPopMatrix();
``````

etc…

There’s gotta be a way to generate the pattern so my Draw function isn’t 100’s of lines long right? Perhaps something with for loop? Do you guys have any recommendations?

thanks

it sounds like you are one my students for these kinds of questions feel free to email the mailing list (ie, homework related questions)

you could make a function that does this:

``````void drawWwithRotation( float x, float y, float rotation){
ofPushMatrix();
ofTranslate(x,y);
ofRotate(rotation);
drawW(-40,-40,20,80);
ofPopMatrix();
}
``````

then your code in draw would look like:

``````drawWwithRotation(50,50, mouseX);
drawWwithRotation(150, 50, mouseX);
drawWwithRotation(250,50, mouseX);``````

then if you felt like this was a pattern:

``````drawWwithRotation(50,50, mouseX);
drawWwithRotation(150, 50, mouseX);
drawWwithRotation(250,50, mouseX);
``````

you could do:

``````for (int i = 0; i < 3; i++){
drawWwithRotation(50 + 100*i,50, mouseX);
}``````

Awesome! Thanks Zach. Yes I’m in your class now. Will email the mailing list so they can benefit from the answers.
