SCRP is a CAOS command used to mark the beginning of a script.
scrp family(int) genus(int) species(int) script_number(int)
*events to happen
Note that a SCRP command needs to have its closing command, ENDM.
Family, genus, or species can be entered as 0 for wildcard matching, like the mating script for creatures:
scrp 4 0 0 34 *stuff endm
Using wildcard matching, you can have 1 script instead of having 6 scripts (one for each species and sex).
The following script will change the name of the Hand to Banana when any gadget is activated (pushed):
scrp 3 8 0 1 hand "Banana" endm
