Kogics

Hi Joe,

we are doing some really cool stuff here at my school.

Good to hear that! Would you mind sharing your school name/location?

How does the following work for what you have in mind? This plays with the idea that 'bigger' squares are red and 'smaller' squares are blue (and can later be extended to do a smooth gradient between two colors).

def sq(n: Int) {
    if (n > 100) {
        setFillColor(red)
    }
    else {
        setFillColor(blue)
    }
    repeat(4) {
        forward(n)
        right()
    }
}
clear()
sq(120)
sq(80)

Note for later: if-else really comes into its own when you start using recursion.

Btw, what version of Kojo are you using? Have you tried the (recently released version with the) Instruction Palette (http://kojoenv.wordpress.com/2013/01/30/new-kojo-release-290113/)? You might find this useful at the 'beginner' stage.

Cheers,
