Passing struct "structures"

08-18-2008, 04:08 AM

how do i pass a particular, created struct and its methods over to another struct w/c i will use to execute the methods of the former?

Example:

i create from struct: SPELL A an instance A in an ability trigger then pass it over to another struct: EFFECT, w/c will execute A's functions/methods. in the struct: EFFECT, how do i identify the struct to be run (A) its "struct-type" (SPELL A) and its associated methods (those in struct SPELL A); how do i execute SPELL A's methods for instance A in struct EFFECT?

Vexorian	Please explain what you want to do. Cause that example you just posted is very confusing.

fX_	i want to treat the ability struct as an object, operated on by the EFFECT struct; this, so i can "open it up" - change values, terminate it, etc. i want to be able "pause", transfer(spell steal), "resist", block, etc. spell effects. i do not know how to have my operator, EFFECT, open the structs up and manipulate them at its table (library Effect).

the-thingy	From my understanding of what you're saying (you want to be able to use struct B's methods for struct A instances?), couldn't you make struct B a parent of A i.e. (not sure on whether you can use struct B's members, or static methods) JASS: struct B ... endstruct struct A extends B ... endstruct

fX_: I am quite sure interfaces are the solution to this issue, if after reading the interfaces part of the manual and the sample that comes in jasshelper/samples you cannot understand it, I would have to post code, but in order to post code that does what you want to do, you will have to describe what you truly intend to do, to do this, explain the behaviors of all your functions, but avoid trying to use words like struct or structure to explain that stuff, think that you are designing the system a lot before thinking about the implementation.
