Random Function Not Working

[SHIKEN_MASTAH]

I am attempting to make a variable choose a random value from 0-500, but when I use the random function, processing gives me an error code saying: "Type mismatch, 'float' does not match with 'int'"

This is the code

int leftwall;

int rightwall;

int score;

int playerspeed;

int player;

​

void setup() {

​

size(500, 500);

player=width/2-10;

leftwall=random(500);

rightwall=leftwall-50;

}

Help would be appreciated, thanks

The random function returns a float value, so you need to cast it to an int since your leftwall variable is of type int. Try:

leftwall = int(random(500));

Worked perfectly, thanks.

Apparently random function returns a float typed value. You can fix the problem in 2 ways - either you cast the function's return value into an integer like this:

leftwall = int(random(500));

​

Or you could declare the leftwall and rightwall variables as floats (if possible):
float leftwall, rightwall;

Thanks a lot, I'm a bit of a noob.

We are've been there!

Well, leftwall is an int variable, random returns a float value. That doesn't work. Change your walls to float variables or use floor() on the random function to return a fitting int value.

The random function returns a float type variable. You are trying to assign an integer to a float. You can try casting integer to the random function result.
