Hi everyone, I would really appreciate the help trying to figure out this code. I have been working at it for hours and I haven’t gotten any progress on it at all. I hope that you are able to help in any kind of way. The image below is supposed to be the outcome of the code. Thank you

thank you!
this code is not runnable
Did you write the code?
I wonder about the \_ . Did you put them there or your teacher?
What have you tried, where are you stuck?
**Remark**
Some things should be clear, for example: rotate( … );
take a guess, what has to be written there?

No, I didn’t write the code it was given to me like that from my teacher. I put the underscores there to signify the empty space. I have tried input the x,y, s, angle, and alpha to the translate, rotate, and scale but it didn’t work and I am confused about the DrawFlower(); part on what to put in there.

Do you know the purpose of a function?
As you can see, the function name is DrawFlower and some numbers are passed to it (which are then stored in variables (that are known within the function))
- x,y signifies the location - use with translate
- s signifies the scale
- angle the angle of the leaf (between 0 and 2 PI)
- and alpha the degree of opaqueness
this is for:

son now you can fill in
```auto
translate( _ , _ );
rotate( _ );
scale( _ , _ );
```
with the variables from the header of the function: x,y and so on
can you show me?

translate( x , y );
rotate( angle );
scale( s , alpha);
would this be wrtie

here you mean the line
` DrawFlower( _ , _ , _ , _ , _ );`
in the function draw() where we actually call (use) the function DrawFlower.
- Now, we want to pass the parameters to the function that the function wants to hear.
- (what we write here: ` DrawFlower( _ , _ , _ , _ , _ );` must match this: `void DrawFlower(float x, float y, float s, float angle, float alpha)` )
We start with (check definition of function DrawFlower(float x, float y, …) ) x,y, which is the position, so we want to pass the position. Let’s use the center of the screen.
Ideas?

WELL DONE!!
almost correct
except
> [@Onipunch777](#):
>
> scale( s , alpha);
we want scale( s , s);
the alpha is for opaqueness of the color so use fill(0, alpha ); please
**so your function is finished now.**
Now look up to my previous post as how to call the function from draw() please

would it be width/2 and height/2 or would it be something completely different?

That’s nice!
Excellent.
Next is ? s.

Would it be between 0.5 and 1 right or would it be just s?

that’s the scale (size)
let’s go for 1 first.
you can replace it with a random number like random(0.5,1) later
**Next is ?**

that was a great way to handle a homework question @Chrisir

the next would be float angle with the DrawFlower

that’s right.
That angle should **increase** with every step.
Let’s put `i` for a test
**i** is our variable from the for-loop, so **i** gets bigger by one every time

so all would be left is float alpha

What’s next?
`alpha`
which is how opaque our color is.
alpha is correct
let’s say 60
* * *
**Now**
try run your code
Does it run?
you need a running code to improve the graphic
I suggest we take care of the angle first.
That’s probably very wrong. Ideas?

WELL DONE!!
Now, we have differences to the initial graphic.
you can use some random.
Do you have ideas where we want to use random?

we could use it in scale
