how to implement method function properly in my program?

in Programming Questions • 2 years ago

i am trying to put my character in a method/function and then calling it, by:

clearing the background

calling the method scene

providing x,y,rotation, and scale parameters of my chararchter method.

then I want to call my charachter method atleast 8 times with dif positions and rotations and scaling!

now my problem is that when I call my object methods, it doesnt show anything!! I need some help with that and what ive done wrong!

I really appreciate your help.

void setup() {

Re: how to implement method function properly in my program?

2 years ago

I see no objects nor methods in your program, I fear you mix up a bit the vocabulary.
In Java, speaking about objects (in the programming sense, at least) implies you have classes: you create objects out of them.
And methods are functions attached to a class, you only use functions there.

I would be surprised your code compiles with a line like:
for(int i=1; i<<9; i++){
i<<9 is a bitshift operation, not resulting in the expected boolean. You probably wanted to write
for(int i=1; i< =9; i++){
and a more idiomatic way to do the loop would be
for(int i= 0; i <9; i++){

Other problem: " I want to call my charachter method atleast 8 times with dif positions and rotations and scaling!"
drawLooLoo(mouseX, mouseY, mouseY/200, - PI/4);
You call the function with the same parameters, so the position won't change: mouseX/Y doesn't change in the loop. And in setup(), I think these values are 0, so you probably draw out of the window.

Try putting the drawing functions in draw(), and vary the parameters in your loop.

Thanks for the response!

can you check to see what is wrong now? I tried to create the parameters inside my function and call it from my draw, but it doesn call it

I would really appreciate it

Re: how to implement method function properly in my program?

Very nice... But I don't see where the problem is, I see the background and your LooLoo character.
Now, if you want to see it move, call it with: drawLooLoo(mouseX,mouseY,0.5,PI/4);
And, more importantly, don't overwrite the parameters at the start of the method!
Ie. remove the lines:

              x=0;
             

              y=0;
             

              lScale=1;
             

lRotate=-PI/4;
as they just make the parameters constant.
