How to add unit to unit group

[Shadow]

I inlined the gui to get GroupAddUnit but how do I add last created units to a unit group?

GroupAddUnit(MyUnitGroup, ? )

 

[Laiev]

call GroupAddUnit(MyUnitGroup, bj_lastCreatedUnit)

 

[Shadow]

is bj_lastCreatedUnit safe to use?

 

[Laiev]

for last created unit in gui, yes...

if you want to use CreateUnit(...) in jass...

just do

local unit u = CreateUnit(....)
call GroupAddUnit(myGroup, u)
set u = null

 

[emjlr3]

you could always still use bj_lastCreatedUnit in the same fashion

 

[Sevion]

No, you'd have to use the BJ to use bj_lastCreatedUnit. The native would not set bj_lastCreatedUnit.

Using it with the native would be the same as using the local unit variable by replacing all instance of u with bj_lastCreatedUnit and not declaring it as a local.

 

[emjlr3]

aren't we talking about JASS here? he is calling a native function, so I imagine he can declare and/or use globals as required

 

[Sevion]

He can't use bj_lastCreatedUnit with the native is what I'm saying. Natives don't automatically set bj_lastCreatedUnit.

 

[emjlr3]

it doesn't use a global or local, and so long as he is using jASS natives, he will need to use a local or global unit to store the last created unit so he can then add it to a group

in which case bj_lastCreatedUnit fits the bill, just the same as a local unit would, minus the deceleration

 

[Sevion]

I think you misunderstood what I was saying...

All I'm saying is that he can't use bj_lastCreatedUnit if he uses the native unless he sets it to the returned unit because the Native does not automatically set the global to that value.

 

[emjlr3]

well then to answer his initial question - yes, it is perfectly safe to use
