Faster and faster squares (Click game)

Processing
1

Hello,
I would like in my game that every 15 seconds the speed of appearance of the edges increases by x time (example the first 15 seconds is 1 square every 1 second then the next 15 seconds will be 1 square every 0.7seconds … etc) except that when I had done it it had worked but in reverse.

This is your variable wait (see this line: if (lastTime + wait < millis()) {).

wait is 1000 (milliseconds, so 1 second)

you can reduce wait by 90 in randomize_square_position()

3

Yes I know but I would like the speed to change every 15 seconds. With what I have already I can just change the speed but it will always remain the same speed it will not increase progressively

4

Okay, make a timer for this and say wait -= 90;

You already have another timer so you should be able to do it on your own

5

To decrease the wait every 15 seconds you can just use

float wait = 1000 - millis()/15000*90; //gradual decrease (\)
float wait2 = 1000 - floor(millis()/15000)*90; //sharp decrease (`-_)

Thanks but it is marked every time: “unexpected token : float”
Its the : "int lastTime = 0 ; " which poses a problem?

I forgot to add a ;
I edited the code now (add a ; before the comment)

Thanks but I have to edit

  if (lastTime + wait < millis()) {             //si j'ai pas click au bout de X temps
    randomize_square_position();                //alors nouveau carré

for this to work because I don’t see any difference with just the variables

yeah don’t worry, I was just providing an alternative. Feel free to use anything, it’s your code after all : P
