GetLocalPlayer() and AddLightning()

[Mooglefrooglian]

I'm trying to create a simple "location" spell for a map. I am using a camera centered one one unit, and the minimap is hidden for various reasons. Thus, it seemed to be mt he best way to detect and find other units would be to create a lightning from the caster to the other units in the map.

What I have works perfectly, except I''m sort of worried about using an AddLightning() inside of a GetLocalPlayer() block.

Would this desync? It didn't seem to in my tests.

        if GetLocalPlayer() == ID then
            set Ray[i] = AddLightning("CLPB", false, GetUnitX(Caster), GetUnitY(Caster), GetUnitX(Unit), GetUnitY(Unit))
            call SetLightningColor(Ray[i], ColorCodesRed[Target], ColorCodesGreen[Target], ColorCodesBlue[Target], 230)
        endif

Should I be using inside the GetLocalPlayer block just setting a string to "CLPB", then creating the lightning out of it?

The answer is yes.

AddLightning extends a handle and therefor desyncs.

lightning is a pseudo handle, therefore using it in GetLocalPlayer()-blocks is fine and does not desync.

Great, two answers that seem contradictory. <3

You can use them (and texttags too, if I remember correctly).

Thank you very much. I've tested it with another person, and neither desynced, and it seems the majority say they do not.

If anyone could explain a "pseudo handle" I'd be much indebted.

They are not normal handles. Normal handles share indexes, eg an index can one moment be a unit, but if the unit is removed a destructable or location can reuse that index.

Floating text uses a fixed 100 sized range of indexes reserved specificly for them. Only floating text may use those indexes. Also floating text can not leak more than 100 times, afterwhich the last one is simply recycled.

Lightning is very simlar.

You may also create local effects with in reason I believe.

As far as I know, handle indexes do not really cause desyncs as long as you create objects for all players. You can however only display them to one player, which is how local multiboards are done and local effects.

Effectually, this means you avoid issues like this one, but are given a cap on the max allowable at a single time.

Erm, pseudo handles.

The list of those is rather long, but most of them arent used anyway (like playerevent and so on)

The ones that might be used, that i know of are pseudo handles are:

image // very useful, although tricky to use
lightning //
ubersplat // have not found any good application for those yet
texttag //
weathereffect // this is the worst pseudo handle blizzard implemented, imo. Do NOT try to use it, unless you have lots of time and a good resource on the bugs with this handle.

Pseudo handles each have their own stack (meaning, H2I() on them returns a value around 0, not around 0x100000). All of them are not relevant to actual gameplay (they cant infulence the outcome of the game).

My bad, deaod is right
