Text¶
f.text_size() sets the size in pixels, and f.text() places a message by its top-left corner. f.text_width() measures a message, which is how the first line is centred.
How it works¶
- f.text(message, x, y) draws words with their top-left corner at (x, y). It uses the current fill colour.
- f.text_size() sets the size in pixels. It stays the same until you change it, so the example sets 40 for the heading and 18 for the notes.
- f.text_width(message) tells you how wide a message is. Centring is (f.width - width) / 2.
- f.text() turns a number into text for you, so f.text(3.14159, 40, 200) works.
- The color= option sets the colour for one call only, as in the frame counter. f.frame_count is the number of frames drawn so far.
Make it yours¶
- Change the message, or change 40 in f.text_size(40), and watch the centring keep up.
- Change the heading colour: f.fill("black") can be any colour name, such as "navy".
- Centre the grey lines too. Use f.text_width() on each one, in the same way as the heading.
- Show a changing number: f.text(f.mouse_x, 40, 280) follows the mouse.
- Write a line several times: for i in range(5): f.text("Hi", 40, 280 + i * 20).
