Help with my error please. " expecting EOF, found 'if' "

void setup() {
size(1000,1000);
fish(250,250,80,40,23,64,232,1);
}
int d;
if (d=1){
void fish(int xOffset, int yOffset, float xBody, float yBody, int r, int g, int b, int d) {
fill(r,g,b);
ellipse(250 + xOffset,250 + yOffset,xBody,yBody); //body of the fish
triangle(250 - xBody/2 + xOffset, 250 + yOffset, 250 - xBody/2 - yBody*sqrt(3)/2 + xOffset, 250 - yBody/2 + yOffset, 250 - xBody/2 - yBody*sqrt(3)/2 + xOffset, 250 + yBody/2 + yOffset); //tail of the fish
fill(255);
ellipse(250 + (0.25)*(xBody)+ xOffset,250 - (0.25)*(yBody) + yOffset,2*sqrt(xBody*yBody/128),2*sqrt(xBody*yBody/128)); // sclera of the fish (white part of the eye)
fill(0);
//ellipse(250 + 0.5*sqrt((xBody+yBody)*(xBody-yBody)) + xOffset,250 - (yBody*yBody/xBody) + sqrt(xBody*yBody/128) + yOffset,2*sqrt(xBody*yBody/pow(2,9)),2*sqrt(xBody*yBody/pow(2,9))); //iris of the fish

}
}
else if(d=0) {
void fish(int xOffset, int yOffset, float xBody, float yBody, int r, int g, int b, int d) {
fill(r,g,b);
ellipse(250 + xOffset,250 + yOffset,xBody,yBody); //body of the fish
triangle(250 + xBody/2 + xOffset, 250 + yOffset, 250 + xBody/2 + yBody*sqrt(3)/2 + xOffset, 250 - yBody/2 + yOffset, 250 + xBody/2 + yBody*sqrt(3)/2 + xOffset, 250 + yBody/2 + yOffset); //tail of the fish
fill(255);
ellipse(250 - (0.25)*(xBody)+ xOffset,250 - (0.25)*(yBody) + yOffset,2*sqrt(xBody*yBody/128),2*sqrt(xBody*yBody/128)); // sclera of the fish (white part of the eye)

//ellipse(250 + 0.5*sqrt((xBody+yBody)*(xBody-yBody)) + xOffset,250 - (yBody*yBody/xBody) + sqrt(xBody*yBody/128) + yOffset,2*sqrt(xBody*yBody/pow(2,9)),2*sqrt(xBody*yBody/pow(2,9))); //iris of the fish

}
}

So basically when I try to run this code, I get an error saying " expecting EOF, found 'if' "

I've only been programming for 1 week now but i'm not sure if what i'm doing is even possible or if it's more of a language issue that i'm saying.

Basically what i want this to do is the following. I have to draw a fish.

              um i have a parameter called "d" If I put in a "1", I want the fish to have a "right" orientation. However if i put in a "0", I want the fish to have a "left" orientation. I think I can do this with an if statement
             

              because there's only 2 states right? left and right. I can say if the "d" value is "1" then draw a fish with a right orientation. 
              
(Now this part i'm not sure... ) else if "d" value is "0" then draw a fish with a left orientation.

             Please help =/

you can't put method definitions like void fish() inside if() statements, they have to be outside.

you need two methods, call them fishLeft and fishRight, exact copies of your two methods, just outside the condition. then just

if (d == 0) {
fishLeft();
}
if (d == 1) {
fishRight();
}

(actually, that's just the start, that'll get you something, but it's all a bit of a mess)
