[edit] Definition

INT signal ( <INT processID|processTypeID> , <INT signal> )

Allows a process/function or a range of processes/functions of certain processType to be controlled in a limited number of ways, by sending signals.

[edit] Parameters

INT processID|processTypeID - The ProcessID of the process or the ProcessTypeID of the type of processes to which the signal is to be sent.
INT signal - The code of the signal that is to be sent to the target process.

[edit] Returns


false - The specified processID|processTypeID was 0 or a processTypeID.
true - The specified processID|processTypeID was a processID.

[edit] Errors

Invalid processID - The process with specified processID is not alive. (Pre 0.90.2 only)
Invalid signal - The specified signal is invalid.

[edit] Notes

To obtain the processType of a function, the operator Type can be used. For a process to send a signal to itself, the local variable id can be used. The parameter signal is passed by way of a set of signals which denote the signal which is to be sent.

To kill all processes at once, except the calling one, use let_me_alone().

[edit] Example

signal( get_id(type enemy) , s_kill ); // Kills a process of type enemy
signal( id , s_kill_tree );            // Kills the process that calls it, and all of its descendants
signal( Type player , s_freeze );      // Freezes all processes of type player so that they are
                                       //     still displayed, but do not execute any code.
