Unit Point Value for automatic indexing

[sethmachine]

Hi,

So suppose I've got a few hundred unique unit types, each of which correspond to some unique object/struct in the map code.

To bind these unit types to these structs, I have been using their unit point value as the index of where the structs are in the global array.

The main function looks something like this:

function main takes nothing returns boolean //for some event
  ...
  local unit u = GetTriggerUnit() //this is the type we want
  local integer upoi = GetUnitValue(u) //this is the unit point value
  …
  call structs[upoi].foo(…)
  …
endfunction

Would anyone have a better way of doing this?

Unit or unit type? Dunno why everyone tries to use something special. For me, any native->struct assignment is done via hashtable.

After thinking about it, your way is probably more ideal. I'd just have to change my code a bit to manage it.

As things are I'm just using a python script to generate the correct assignment each time. It's like killing sparrows with a cannon but it gets the job done and hides all the internals behind the scenes, which is the high level coding experience I think vJASS should be.

Well, at least wrap it in functions.

local Unit U = Unit.getFromUnit(u)
call U.foo(…)

I do not work with the native types anywhere outside of low level header/special tasks. Always go to the struct type asap.

local Unit u = Unit.getTrigger()
