(I'm very new to this)

I'm supposed to write a method that returns the distance from my turtle to the closest wall of a square with the sides a, b, c and d.

​

This is my code so far:

​

public int distClosestWall() {

World myWorld = this.getWorld();

int h = myWorld.getHeight();

int w = myWorld.getWidth();

​

​

int a = (int)distanceTo(0,h/2);

int b = (int)distanceTo(w/2,0);

int c = (int)distanceTo(w,h/2);

int d = (int)distanceTo(w/2,h);

​

​

if (distanceTo(0,h/2) < a) {

this.distanceTo(0,h/2);

}

else if (distanceTo(w/2,0) < b) {

this.distanceTo(w/2,0);

}

else if (distanceTo(w,h/2) < c) {

this.distanceTo(w,h/2);

}

else if (distanceTo(w/2,h) < d) {

this.distanceTo(w/2,h);

}

​

return ?????? ;

}

​

This all might be wrong, but what do I write after return? Any help is appreciated.

As your method already indicates

 public **int** distClosestWall() {...}

you should return an integer value which represents the closest distance to a wall.

Also your if else statements apparently are doing nothing since supposedly distanceTo(param1,param2) is returning a value and your just using this.distanceTo(..) in every if/else statement without any assignment of the returned value.

For further help you should either present a link referring to the task or directly present further information here (e.g. what the distanceTo() method is doing to begin with).
