I want the key “Q” to restart the program, but the reset function isn’t working.

Check out the reset function in my code, and the mousepressed function should give you an idea of how to reset your sketch

your basic idea works here:
```auto
float ang=0;
void setup() {
println("click on canvas and press key [s] stop or [q] run");
}
void draw() {
background(200, 200, 0);
translate(width/2,height/2);
rotate(ang);
ang +=0.01;
line(10, 10, 20, 20);
}
void keyPressed() {
if ( key == 's' ) noLoop();
if ( key == 'q' ) loop();
}
```
but sorry, will not check all that code…
also working with `noLoop();` at all is a unusual concept.

Apologies, seems my suggestion was already implemented. Thanks for pointing it out @kll

pls see his line 540 where this actually is done that way,
i try:
```auto
float ang=-PI/2;
void setup() {
println("click on canvas and press key [s] stop or [q] run or [r] reset");
}
void draw() {
background(200, 200, 0);
translate(width/2, height/2);
rotate(ang+=0.01);
line(10, 0, 40, 0);
}
void keyPressed() {
if ( key == 's' ) noLoop();
if ( key == 'q' ) loop();
if ( key == 'r' ) reset();
}
void reset() {
println("reset");
ang = -PI/2;
loop();
}
```
and my short form also works that way
so must be an other logic problem ???
@Kitty, you are aware that we are limited to read your code
as you not store the whole project ( 12 pictures ) at github
we can not run it.

Inside `void reset()` you seem to be redeclaring global variables:
```auto
// line 560 and upwards:
int rad = 60;
float xpos, ypos;
float xspeed = 2.8;
// ... rest of the code
```
Instead of redeclaring them, only reinitialise them. Does that solve your issue?

So the reset function works now, but only the timer doesn’t?
I think it wouldn’t hurt to take another look at your code and clean it. It’s filled with points of improvements which all might influence the expected outcome. Some examples:
- Inside `void reset()` I still see variables getting declared that are already global variables;
- Inside `void reset()` the same variables get appointed new values several times;
- These two issues are happening elsewhere in your sketch as well (such as redeclaring `float timer` even though it’s a global variable).

Here is the updated code, the timer still doesn’t reset.
Another problem is that the win screen when time reaches 30 it doesn’t work anymore.

Well just taking a fast look, the timer can’t reset because in the line 154 (if I’m not mistaken) you had something like:
```auto
float timer = (millis() + t)/1000;
```
That takes the time since the beginning of the program, using this, the timer resets:
```auto
timer += 1/frameRate; //float timer = (millis() + t)/1000;
```
Also changed the text just to see time with one digit
```auto
text("Time: " + (0 + (int)timer), 10, 20);
```
And trying a little bit the game, I’m not totally sure, but when I reached the 34 secs without die, no more obstacles appeared 🤔🤔

The goal of the game is to survive 30 seconds.
But after 30 seconds the win screen won’t load. So yeah, that’s one of my problems

Okay, I saw the win screen isn’t implemented, but thought the cause of the obstacles stopped was because it was being restarted.
Its the time okay now?

Remove the line from the preset function and move it outside of the function and remove the line which reinitializes it.

I’m not sure, I’ll have to test it out at a later time.
It runs fine when changed on your side, correct?
