[JASS] How to set a unit's size only for one player?

[tarik00555]

I started experimenting with GetLocalPlayer() and I was wondering if it's possible to set a unit's scale only for the local player. I want to set the unit's scale to 0 so the owner of that unit can't see the unit but everyone else can.

I know of this function:

SetUnitScale(unit, x, y, z)

So I was wondering if this is possible. I read somewhere that it's safe to change the vertex color of a unit only for the local player, so I'm assuming you can change the scale too.

I managed to figure it out!

Pick every unit owned by player ...
and do that SetUnitScale(GetEnumUnit(), 200, 200, 200)

(I think you can do that with only native functions)

If you set the scale to 0, you can still drag-select it can't ya?
So I'd rather hide the unit for a specific player instead.

Sorry I didn't read the post and just gave an answer to the title.

Here is the real answer:
Loop through all players:
if LocalPlayer = owning player then
Set unit scale to 0, 0, 0
else
Set unit scale to 1, 1, 1

I think that this wouldnt work but you could try set vertex coloring with 100% transparency instead
(As we are talking about colors, make sure you check out what the BJ function does before you remove it... you might even keep the BJ instead of the native.)

EDIT:
Hide unit does not hide a unit does it?
The editor sais that it is only hidden for regions.

this will desync if the player that cant see the unit will try to do enter the unit's collision range with his unit's collision range(basically step over it).

I have tried this personally before, I wanted to hide units inside village for only players that finished certain quest, but there is no easy method to do this

i dont know about setting the scale, but setunit x/y works locally ive tested it, works 100% no desynchronization. you might want to disable the unit's minimap image too

 

[edo494]

SetUnitX/Y will also desync if you try to step to position where the unit should be for another player, because you desync the game states(Player A's game thinks your unit stands there, Player's B game thinks your unit cant be there, because some other unit is standing there)

Why not use transparency?

 

[DracoL1ch]

everything which mess with object's behaiour CANNOT be runned locally.
nothing in WC3 cares about unit's tint, size - but everything cares about his X/Y/life.
so you may assume tint and size can be modified locally - what does it matter, if enemy will see black or standard model? but messing with unit's coorinated will lead to desync as soon as enemy will try to do something with moved unit.
it's safe as long as enemy can only "watch", but once it starts to be interactive, you have no rights to do such stuff locally.

This. Just use SetUnitVertexColor() to make the unit completely transparent.
