Name

rotate()

Class

PShape

Description

Rotates a shape the amount specified by the angle parameter. Angles should be specified in radians (values from 0 to TWO_PI) or converted to radians with the radians() method.

Shapes are always rotated around the upper-left corner of their bounding box. Positive numbers rotate objects in a clockwise direction. Transformations apply to everything that happens after and subsequent calls to the method accumulates the effect. For example, calling rotate(HALF_PI) and then rotate(HALF_PI) is the same as rotate(PI). This transformation is applied directly to the shape, it's not refreshed each time draw() is run.

Examples

  • PShape s;
    
    void setup() {
      size(100, 100);
      s = loadShape("ohio.svg");
    }
    
    void draw() {
      background(204);
      shape(s);
    }
    
    void mousePressed() {
      // Rotate the shape each time the mouse is pressed
      s.rotate(0.1);  
    }
