This function will return the maximum width (in pixels) of the input string, taking into account the line separation and line-break width (which is defined as the number of pixels that the string can occupy before a line break is inserted). It is very handy for calculating distances between text elements based on the maximum width of a string that is split over several lines as it would be drawn with draw_text_ext() using the currently defined font. Separation and width can be set to -1 to get the default spacing.
string_width_ext(string, sep, w);
| Argument | Type | Description |
|---|---|---|
| string | String | The string to measure the width of. |
| sep | Real | The distance in pixels between lines of text as if the string was being drawn. |
| w | Real | The maximum width (in pixels) of the string before a line break as if the string was bring drawn. |
var ww = string_width_ext(str_Story_Text[1], -1, 100);
draw_text_ext(32, 32, str_Story_Text[1], -1, 100);
draw_text_ext(32 + ww, 32, str_Story_Text[2], -1, 100);
The above code will get the width of the given string, taking into account the line separation and line-break width, and then draw two lines of text, using the returned total string width as a separator.
