line()
Description
Line is a function that draws a line using two points. For most shapes you can set the color using fill() , but a line is only a stroke, so you must use stroke() to set the color.
Parameters
line(x1, y1, x2, y2);
- x1 - (float) the first point's x position
- y1 - (float) the first point's y position
- x2 - (float) the second point's x position
- y2 - (float) the second point's y position
Example
void update()
{
// set the stroke color to orange
stroke(color(255, 160, 20, 255));
// draw a line from (100, 100) to (100, 200)
// x1 y1 x2 y2
line(100.0f, 100.0f, 500.0f, 100.0f);
// set the stroke color to light blue
stroke(color(0, 160, 255, 255));
// draw a line from the origin to the mouse position
line(0.0f, 0.0f, mouseX, mouseY);
