Definition

INT write_int ( <INT fontID> , <INT x> , <INT y> , <INT alignment> , <INT POINTER var> )

Writes an integer to the screen, which will be automatically updated when the value of the integer changes. The integer will remain on the screen until deleted with delete_text().

Parameters

INT fontID	- The FontID of the font to be used for the text.
INT x	- The X coordinate of the text.
INT y	- The Y coordinate of the text.
INT alignment	- The type of alignment.
INT POINTER var	- A pointer to an integer.

Returns

INT : TextID

0	- Error. The text could not be obtained or was empty.
!0	- The TextID of the text.

Notes

There is a limit of 511 texts to simultaneously exist on the screen. The program will crash with an error when this number is reached.

The text depth can be changed by adjusting the global variable text_z.

Instead of write_int(), write_var() can be used for the same purpose, which is a more general function that allows you to write variables of any type to the screen.

Example

Program test;
Global
    My_integer=0;

Begin
    Write_int(0,320/2,200/2,4,offset My_integer);
    Loop
        My_integer=rand(1,1000);
        Frame;
    End
End

Used in example: rand()

This will result in something like:
