Definition
INT write_int ( <INT fontID> , <INT x> , <INT y> , [<INT z>] , <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 z | - The depthplane of the text (optional, introduced in version rc282). |
INT alignment | - The type of alignment. |
INT POINTER var | - A pointer to an integer. |
Returns
INT : TextID
-1 | - Error. |
>=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.
Errors
Too many texts onscreen | - There are too many texts on the screen. |
Example
Program test; Private my_integer=0; Begin write_int(0,320/2,200/2,4,my_integer); Repeat my_integer=rand(1,1000); frame; Until(key(_ESC)) End
