[General] how to check if player has unit?

[stan0033]

I need to check if player has specific hero type. Any ideeas?

If you want to check if he has hero (a hero that he created, but it does not matter to you if that hero is currently alive or dead), then you can make boolean array check whenever new unit enters area, if unit-type of that unit is your hero, you save "true" into the boolean and as an index you use player's number.

Then it is simply checking if bool for that player == true

Events
    Unit enters playable map area
Conditions
    Unit-type of triggering unit == your hero
Actions
    Set bool[player number of (triggering player)] = true

------
then you check if bool[X] == true (X is number of player you want to check - e.g. 1 for player 1 (Red) )

----
Alternatively, you can use this trigger as well
Events
    Unit dies
Conditions
    Unit-type of triggering unit == your hero
Actions
    Set bool[player number of (triggering player)] = false

This way it will be false if that hero is dead

set tempgroup = units Footmen owned by Player 1
if units in tempgroup > 1

cleanup leaks.

It's something like that, hell I'm sure it's even easier.

Since you probably have a unit group that stores all units in it when they enter map loop through that and check if the player owns unit of type.

Tell me, how many "unit" that you want to be checked ?
I would suggest a boolean approach in which, whenever a unit that is newly owned by a player, set the boolean to true.
If the unit dies, or whatever, set it to false.

To check, simply check the boolean instead to enumerate all the units in the map, that would be too power-consuming method.

afaik the only choices you have are to either
a) use the unit group and iterate through each unit and check if the unit-type is in the group ==> simple trigger (in PoW of the developer), but it's a heavy process, more so if you have many units in game

b) do it via the boolean like I and Defskull wrote... these may seem more complex (requires 3 triggers), but those are simple triggers and way more efficient than iterating through each unit that player has.

@Nichilus
That only works if you have 1 Hero per Player.
We need to know how many Hero/Unit he intend to allocate per Player first.

But if he only needs one per Player, your trigger would work best.

Because judging by this;

I need to check if player has specific hero type...

I'm sensing that there would be more than 1 check to be done, say, he wants to check from the pool of 6 units.

Either way, we must wait for his more in-depth explanation so that we can adjust our triggering scope to adapt his desired situation.

Actually there is only one hero per player, @Defskull

Then use Nich's suggestion directly.
