"The Method is not Applicable for the Arguments" - Why does it say this?

in Programming Questions • 1 year ago

I cannot keep working because Processing doesn't like something that I am doing..

It says The Method is not Applicable for the Arguments(int,int,int,int)

Do you know what's going on?

Thanks!

Copy code

int gridHeight;
int gridWidth;
float circleRadius;
int drawGridOfCircles;
void setup() {
gridHeight=5;
gridWidth=10;
size(600, 600);
}
void draw() {
background(255);
fill(255,0,0);
circleRadius =mouseY/20;
drawGridOfCircles(gridHeight, gridWidth, mouseX, mouseY);
//drawGirdOfCircles(20,3,50);
}
void drawGridOfCircles() {
//void drawGridOfCircles(int a, int b, float c){
for (int i=1;i<gridWidth;i=i+1) {
for (int j=1; j<gridHeight; j=j+1) {
ellipse(i*20, j*20, circleRadius, circleRadius);
}
}
}

I'm assuming that it highlights line 27...

That would be because you are trying to call drawGridOfCircles() with invalid parameters.
The call (line 27):

Copy code

drawGridOfCircles(gridHeight, gridWidth, mouseX, mouseY);

and the declaration (line 32):

Copy code

void drawGridOfCircles() {

's parameters do not match.
Either clear the parameters for the call or create four ints for the declaration.

Yes, it's line 27 (now 31).

I need to create four ints for the way I have to keep working. So now I did like this, but it doesn't like it neither..

Maybe this is not the right way to declare the ints?

Thanks!

Copy code

int gridHeight;
int gridWidth;
float circleRadiusX;
float circleRadiusY;
int drawGridOfCircles;
void setup() {
gridHeight=5;
gridWidth=10;
size(600, 600);
}
void draw() {
background(255);
fill(255,0,0);
circleRadiusX =mouseX/20;
circleRadiusY =mouseY/20;
drawGridOfCircles(gridHeight, gridWidth, circleRadiusX,circleRadiusY);
}
void drawGridOfCircles() {
//void drawGridOfCircles(int a, int b, float c){
for (int i=1;i<gridWidth;i=i+1) {
for (int j=1; j<gridHeight; j=j+1) {
ellipse(i*20, j*20, circleRadiusX, circleRadiusY);
}
}
}

Lines 31 and 36 must match (same numbers of parameters).

You call it with: int int float float

Thus

void drawGridOfCircles ()

would need 4 parameters.

On the other hand:

Leave 36 as it is.

Line 31:

drawGridOfCircles () ;

without Parameters

Since the vars you want to pass are global vars anyway - no need to pass them.

That's great, and I understood what you mean. Now I was able to keep going on my work.

Thank you!

I am having exactly a similar problem here, and I still don't get what's wrong.

Line 11, it cannot find anything called drawSquares and so i am stuck again.

Do you know what do I miss now?

Thanks

Copy code

int x =0;
int y =0;
void setup() {
{
size(400, 400);
fill(0);
drawSquares=rect(x, y, 20, 20);
drawSquares(19);
}
}
void drawSquares (float number) {
while (x<width) {
while (y<height) {
rect(x, y, 20, 20);
y=y+height;
}
y=0;
x= x+40;
}
}

The compiler thinks you are trying to assign a variable called drawSquares to be the value of rect(x, y, 20, 20);, which is void.

What exactly are you trying to do?
Is just:

Copy code

rect(x, y, 20, 20);

what you need?

Having a number (as you see in my example, in line 13 -drawSquares(19)-), I have to draw a line of Squares using while loop.

I think the rest of the code should work, but it doesn't let me go forward.

What do you think I should do? It doesn't like anything I am doing right now..

No, what are you trying to achieve with line 11?

It should be the first square that I am going loop using the while loop.

It is in position x, y and dimension 20, 20

Quite frankly, I don't understand what you're doing.
Do you need the portion of it that comes before the equals sign?
What happens when you get rid of that line?

At the end I did like this, I took it away and I called at the top. It's just a simple line of squares, but it works!

Thank you so much for all your help!

Copy code

int x =0;
int y =0;
float drawSquares;
void setup() {
size(400, 400);
fill(0);
drawSquares(19);
}
void drawSquares (float number) {
while (x<width) {
while (y<height) {
rect(x, y, 20, 20);
y=y+height;
}
y=0;
x= x+40;
}
}

Yes! To get rid of that line was such a great idea!
