Note that this will set the font to use for all subsequent draw text calls, and so can be called once at the beginning of the game - in any event, not just the Draw Event - and all draw text actions will use the set font. However if you require multiple fonts in your game, then you will need to call this action before drawing any text with the required font.
The above action block code sets the draw colour, the font, and the alignment for some text that is drawn.
