Write var
From FenixWiki

[edit] Definition
INT write_var ( <INT fontID> , <INT x> , <INT y> , <INT alignment> , <VARSPACE var> )
Writes a variable of any kind to the screen, which will be automatically updated when the value of the variable changes. The variable will remain on the screen until deleted with delete_text().
[edit] 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. |
VARSPACE var | - The name of any variable. |
[edit] Returns
INT : TextID
-1 | - Error. |
>=0 | - The TextID of the text. |
[edit] Notes
Please note that for the varspace var parameter no pointer should be filled out, while write_int()/write_string()/write_float() do require a pointer.
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_var(), write_int() could be used to write an int to the screen, write_string() for a string, write_float() for a float.
[edit] Errors
Too many texts onscreen | - There are too many texts on the screen. |
[edit] Example
Program test; Global my_integer=0; string my_string="Fenix"; Begin write_var(0,0,0,0,my_string); write_var(0,320/2,200/2,4,my_integer); Repeat my_integer=rand(1,1000); frame; Until(key(_ESC)) End
