I need some help with the project "Moles in holes"

var drawMole = function(moleX, moleY) {
var moleX = 248;
var moleY = 185;

noStroke();
fill(125, 93, 43);
ellipse(moleX, moleY, 60, 60); // face
fill(255, 237, 209);
ellipse(moleX, moleY+10, 33, 28);
fill(0, 0, 0);
ellipse(moleX-10, moleY-15, 10, 10); // eyes
ellipse(moleX+10, moleY-15, 10, 10);
ellipse(moleX, moleY-5, 10, 10); // nose
ellipse(moleX, moleY+10, 20, 5); // mouth

};

background(52, 168, 83); // green grass
fill(0, 0, 0);
ellipse(200, 200, 100, 30); // holes!
ellipse(70, 119, 100, 30);
ellipse(300, 60, 100, 30);
ellipse(297, 350, 100, 30);
drawMole(moleX, moleY);

Please look at this and see if anyone can find the error. The oh noes guy keeps saying this** you are trying to use MoleX and moleY in your call to the drawMole function, This doesn't work because function parameters and variables declared inside a function can't be seen outside of that function (they are"undefined" outside of the function). This will be explained more when we talk about local and global variables.

If anyone can find the error please advise and thanks!

Hi, hunterw0808.

What Oh Noes is basically saying is that you have a local variable being used like a global one.

Or, that a variable that you define in the function stays in the function. That's a local variable. A global variable is a variable defined outside of a function, and can be used anywhere -- not just restricted to a function.

However, you don't need to put a global variable in the parameters for the drawMole() function. You can just use x and y coordinates, and the entire mole will move to those coordinates.

Let me know if you have any questions! :)
