[edit] Definition

A text is a text written on screen with texts functions, like write() or write_int(). A text is addressed using the associated TextID.

There are two kinds of texts:

• Static text is any text written with write(); it is static, because the content of the text cannot be changed after writing, but the text can be moved and deleted.
• Dynamic text is any text written with write_xxx() functions; it is dynamic because the content of the text always reflects the current value of the variable specified. Of course moving and deleting is also possible.

[edit] Writing texts

There are multiple ways to write texts: the write() function, write_xxx() functions and the write_in_map() function. With the first two, some the global variable text_z is important and with all three of them, the following are important:

• The functions set_text_color() and get_text_color()
• The font
• The alignment
• The global variable text_flags

Also the function move_text() can be handy, as it moves a previously written text to a different location.

[edit] Example

Program texts;
Const
    maxtexts = 10;
Private
    int textid[maxtexts-1];
    string str;
    float flt;
Begin

    // Set FPS
    set_fps(60,0);

    // Init text settings:
    text_z = 0;
    text_flags = 0;
    set_text_color(rgb(255,255,255));

    // Write some texts
    textid[0] = write(0,0,0,0,"FPS:");
    textid[1] = write_int(0,30,0,0,&fps);
    textid[2] = write_string(0,160,95,1,&str);
    textid[3] = write_float(0,160,105,0,&flt);

    // Show z workings
    set_text_color(rgb(50,150,150));
    textid[4] = write(0,20,20,0,"Underlying text");
    text_z = -1;
    set_text_color(rgb(255,255,255));
    textid[5] = write(0,22,22,0,"On top text");

    // Update the texts until ESC is pressed
    Repeat
        // Notice the texts get updated as the values of str and flt changes.
        // The same goes for the value of fps.
        str = "This program is running for " + timer/100 + " seconds.";
        flt = (float)timer/100;
        frame;
    Until(key(_esc));

    // Delete the texts (this section would be good for OnExit)
    for(x=0; x<maxtexts; x++)
        if(textid[x]!=0)
            delete_text(textid[x]);
        end
    end

End

Used in example: set_fps(), set_text_color(), write(), write_int(), write_string(), write_float(), key(), delete_text(), text_z, text_flags, fps
