Functions

The syntax for functions is as follows:

function <name>(<parameter 1>: <data type 1>, <parameter 2>: <data type 2>, ...) returns <return value data type>:
<expression>
return <expression>

Example:

func fibonacci(x: Number) returns Number:
    if x <= 1:
        return x 
    else:
        return fibonacci(x - 1) + fibonacci(x - 2)
            
info(fibonacci(10))

Output:
55

For a non-returning function, remove the returns subclause in the function header, as well as the clause in the function body.

Example:

func printMe(txt: Text):
    txt2: Text = "00" + "0"
    txt2 += "0"
    txt += txt2
            
    info(txt)
            
printMe("#FF")

Output:
#FF0000

IMPORTANT: Since draw commands should be placed at the end of the source code, they cannot be enclosed inside functions. A workaround is to return the object to be drawn, then draw it outside the function.

Example:

func draw_circles(x: Number) returns Number:
    if x == 0:
        return 0
                
    y += 30
    circles += circles(60, y, 20)
    draw_circles(x-1)

    return 0
            
circles: Object = circle(60, 20, 20)
y = 20

draw_circles(3-1)

circles.draw(1, 1000)
