Script
Introduction
Clonk supports its own scripting language: C4Script.
Object definitions and scenarios can contain a script. Function calls made from scenario scripts are considered "global" calls. Function calls made within an object script are considered "local" calls.
For further information on the two types of script see
object scripts and
scenario scripts.
C4Script uses a C-style syntax. It includes
operators,
variable declarations, compound statements, conditional statements (
if) and loops (
for and
while).
Debugging
Activate the debug mode in the developer section of the game options to have additional error messages displayed. Anyone writing scripts should do this.
Functions
As in other programming languages you can define
functions in C4Script:
func CreateRock()
{
[Erzeugt einen Stein|Image=ROCK]
CreateObject(ROCK,50,50);
return(1);
}
Directly following the function name you can include a short descriptive text, an icon reference (object ID of the object whose image is to be used), and a conditional statement for when to display the function in the context menu, all within a set of [ ] brackets, separated by a | symbol.
Variables/Parameters
Variables can hold values of type int, bool, id, string, or object. Any parameter not directly specified in a function call will hold the default value 0. Functions can have a maximum of ten parameters.
Comments
Scripts may contain code comments in C-style. Comment test will be completely ignored when the script is comipiled for execution.
func MeineFunktion() // Ein Kommentar bis zum Ende der Zeile
{
Message("Dieser Code wird ausgeführt"); /* Ein Kommentar in einem Block */ Message("Dieser auch");
return(1);
}
