Description
This function is what runs your program for you. When you write setup() and draw() functions in your work space, then you call Run with the names of those functions to loop your program.
Setup will be called exactly once at the beginning of the program. Draw will be called once per frame for the life of the program.
The setup() and draw() functions must take no parameters and return nothing.
Example Usage
1void setup(void)
2{
3 /* Set the size of the window */
4 size(500, 500);
5}
6
7void draw(void)
8{
9 /* Set the background color to black every frame */
10 background(0, 0, 0, 255);
11
12 /* Draw a rectangle at the mouse position */
13 rect(mouseX, mouseY, 50, 50);
14}
15
16int main(void)
17{
18 /* Run the program */
19 Run(setup, draw);
20}
