[vJASS] speed difference

[kStiyl]

I have a system dealing with unit movements
i happen to save their coordinates periodically onto variables (all systems changing unit's x/y also change these variables)

would it be better to get their coordinates by just doing
x[unitId] or just use GetUnitX(unit)?

 

[mckill2009]

you dont have to use Table for that, GetUnitX is fine...

its real array though.. not hashtable

i was thinking if theres benefit to using it because the system saves the coordinates for its own uses..

 

[mckill2009]

I dont think that's even possible coz array variables has an 8190 limit, using
unit of units are millions, besides, x[unitId] calls 3 while GetUnitX(u) calls 2...

mckill2009 : ever heard about unit indexers ? ...

Now it depends, if you need it several times or not.
If you use it several times just after storing it, a not array variable would be even better.

mckill2009 : ever heard about unit indexers ? ...

No, but I assume NOW that unitID is same as custom value, so its possible...
what I was talking about is the unitId of a particular unit, means something
like 'Hamg' and a-like which is really not possible...

 

[Troll-Brain]

Unit indexers use the custom value, and unless you have more than 8190 units indexed on the map at the same time it works just fine.
The usual name to get the unit "id" is GetUnitId, but it inlines to GetUnitUserData.

Now, why the hell you are talking about unit rawcodes ?!

No, but I assume NOW that unitID...

pardon, but I know unit indexers as I even used that in my AI-system, what I dont know is unitID's...My mistake there...

Now, why the hell you are talking about unit rawcodes ?!

coz I thought that unitID==GetUnitTypeId(), that's why I said millions XD...
