Definition

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

Writes a floating point variable to the screen, which will be automatically updated when the value of the variable changes. The floating point variable 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.
FLOAT POINTER var	- A pointer to a floating point variable.

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_float(), 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.

Errors

Example

Program test;
Global
    Float My_float=3.14159265;

Begin
    Write_float(0,320/2,200/2,4,offset My_float);
    Loop
        Frame;
    End
End

This will result in something like:
