Hi all,
I’m wondering if anyone has any insight into why some functions, will affect the next frame in the draw loop, while others won’t.
For example:
1. the fill() function (written at the bottom of the draw loop) will affect the ellipse (written at the top of the draw loop)
```auto
function setup() {
createCanvas(400, 400);
}
function draw() {
ellipse(100, 100, 100, 100);
fill(255, 0, 0);
}
```
1. the translate() function (written at the bottom of the draw loop) will NOT affect the ellipse (written at the top of the draw loop)
```auto
function setup() {
createCanvas(400, 400);
}
function draw() {
ellipse(100, 100, 100, 100);
translate(200, 200);
}
```

That’s true.
The Matrix gets resetted (like with popMatrix()) at start of the draw() function
The colors get not

The main canvas got all of its transformation methods reset before each **draw()** callback iteration:
- [reference | p5.js](http://p5js.org/reference/#group-Transform)
Other method groups like color stick on the main canvas for each **draw()**:
- [reference | p5.js](http://p5js.org/reference/#group-Color)
Canvas created via **createGraphics()** don’t auto-reset its transformation btW:
- [reference | p5.js](http://p5js.org/reference/#/p5/createGraphics)

I would say, why do some parameters (set by functions like fill or translate or rotate…) stay fixed when draw() begins a new cycle and others don‘t
