[JASS] Creating Forces?

[Blue_Jeans]

Creating Forces and assigning an upgrade?

I've taken a 2 year break from Warcraft III, and now I'm getting back into it. Horay for me. However, it means I've lost almost everything I learned.

Problem:
In Scenario > Force Properties I've created two forces, Alliance and Horde. Now... how do I use those forces in a trigger? Do they have a global variable or something?

I'd also like to know how to create a force in JASS, I can't seem to remember all the aspects of doing this. I mean, selecting a player in a slot and then adding them to a force depending on the slot they are in. Then depending on which force they are in, research an upgrade.

Obviously, I've rusted

I don't think the Force Properties affect the triggers. (basically, I don't think it creates a global) Thus, you will have to manually group them as a force. In GUI, it is a player group. In JASS:

local force Alliance = CreateForce()
call ForceAddPlayer(Alliance,Player(0))

Or however you'd like to do it.

//============================================================================

Welcome back.

I added some code to my first post. I just need to figure out how to add each player to his corresponding force and it SHOULD work. Think so? I also realized that I don't need to create a local force, simple set up the global forces (because they will be used elsewhere) and then run an upgrade for each force. I realized the code is overcomplicated, I'll fix it in a moment.

And yes, those udg_'s are defined. And I keep udg_ there to remind me that they are globals, in case you are wondering.

Edit: Updated code. Think it will work?

 

[PurgeandFire]

Yep. You can just look in the force properties and copy whatever forces each player is in; and then on map initialization, you would do something like this:

function InitializeForces takes nothing returns nothing
    local integer i = 0
    set udg_Alliance = CreateForce()
    set udg_Horde = CreateForce()
    loop
        exitwhen i==6 
        call ForceAddPlayer(udg_Alliance,Player(i))
        call ForceAddPlayer(udg_Horde,Player(i+6))
        set i = i+1
    endloop
endfunction

For this example, it will create the forces, and then add Player 1, 2, 3, 4, 5, and 6 to Alliance, and 7, 8, 9, 10, 11, and 12 to the Horde.

@Your code: Well, since it isn't responding to a player event, GetTriggerPlayer() would return as null. You might be looking for GetLocalPlayer() instead, which refers to the player currently running the code.

Noted.

Okay, I have the following code. I added a piece so that each player in the force gets their starting gold set. It helps me debug whether it works, plus it needs done anyway. I also added the CreepSpawnPreload() function so that creeps will spawn based on the upgrade. I know the system works, no trouble there. However, in game this doesn't work:

InitForces

scope InitForces

private function Alliance takes nothing returns nothing
    call SetPlayerState( GetEnumPlayer(), PLAYER_STATE_RESOURCE_GOLD, 900 )
    call SetPlayerTechResearched( GetEnumPlayer(), 1, udg_ResearchId[0] )
endfunction

private function Horde takes nothing returns nothing
    call SetPlayerState( GetEnumPlayer(), PLAYER_STATE_RESOURCE_GOLD, 900 )
    call SetPlayerTechResearched( GetEnumPlayer(), 1, udg_ResearchId[25] )
endfunction

private function Actions takes nothing returns nothing
    local integer i = 0
    call CreepSpawnPreload()
    set udg_Alliance = CreateForce()
    set udg_Horde = CreateForce()
    loop
        exitwhen i==6 
        call ForceAddPlayer(udg_Alliance,Player(i))
        call ForceAddPlayer(udg_Horde,Player(i+6))
        set i = i+1
    endloop
    call ForForce(udg_Alliance, function Alliance )
    call ForForce(udg_Horde, function Horde )
endfunction

//===========================================================================
public function InitTrig takes nothing returns nothing
    local trigger trig = CreateTrigger(  )
    call TriggerAddAction( trig, function Actions )
endfunction

endscope

No gold is set, and my footmen don't spawn as if the research isn't done.

I forget whether or not you need to add initializer or not. (I think you could just use "InitTrig" before, but I am not sure. You can try adding an initializer anyway)

scope InitForces initializer Init

private function Alliance takes nothing returns nothing
    call SetPlayerState( GetEnumPlayer(), PLAYER_STATE_RESOURCE_GOLD, 900 )
    call SetPlayerTechResearched( GetEnumPlayer(), 1, udg_ResearchId[0] )
endfunction

private function Horde takes nothing returns nothing
    call SetPlayerState( GetEnumPlayer(), PLAYER_STATE_RESOURCE_GOLD, 900 )
    call SetPlayerTechResearched( GetEnumPlayer(), 1, udg_ResearchId[25] )
endfunction

private function Actions takes nothing returns nothing
    local integer i = 0
    call CreepSpawnPreload()
    set udg_Alliance = CreateForce()
    set udg_Horde = CreateForce()
    loop
        exitwhen i==6 
        call ForceAddPlayer(udg_Alliance,Player(i))
        call ForceAddPlayer(udg_Horde,Player(i+6))
        set i = i+1
    endloop
    call ForForce(udg_Alliance, function Alliance )
    call ForForce(udg_Horde, function Horde )
endfunction

//===========================================================================
private function Init takes nothing returns nothing
    local trigger trig = CreateTrigger(  )
    call TriggerRegisterTimerEvent(trig,0,false)
//you can either: 
//   - checkmark "run at initialization"
//   - use this timer event
//   - or just directly replace all this functions' contents with "call Actions()"
    call TriggerAddAction( trig, function Actions )
endfunction

endscope

I've tried all three methods you mentioned (who knows if I did them correctly), but I couldn't get them to work. I uploaded the map to my first post. Help if you can! I can't see why it doesn't work. If you cheat and give yourself gold, research the call rifleman upgrade and he should appear every 30 seconds...

 

[PurgeandFire]

Works for me (at least the gold part, didn't check the other one) when I add this initializer:

scope InitForces initializer InitForces

private function Alliance takes nothing returns nothing
    call SetPlayerState( GetEnumPlayer(), PLAYER_STATE_RESOURCE_GOLD, 900 )
    call SetPlayerTechResearched( GetEnumPlayer(), 1, udg_ResearchId[0] )
endfunction

private function Horde takes nothing returns nothing
    call SetPlayerState( GetEnumPlayer(), PLAYER_STATE_RESOURCE_GOLD, 900 )
    call SetPlayerTechResearched( GetEnumPlayer(), 1, udg_ResearchId[25] )
endfunction

private function Actions takes nothing returns nothing
    local integer i = 0
    set udg_Alliance = CreateForce()
    set udg_Horde = CreateForce()
    loop
        exitwhen i==6 
        call ForceAddPlayer(udg_Alliance,Player(i))
        call ForceAddPlayer(udg_Horde,Player(i+6))
        set i = i+1
    endloop
    call ForForce(udg_Alliance, function Alliance )
    call ForForce(udg_Horde, function Horde )
endfunction

//===========================================================================
public function InitForces takes nothing returns nothing
    local trigger trig = CreateTrigger(  )
    call TriggerRegisterTimerEvent(trig,3,false)
    call TriggerAddAction( trig, function Actions )
endfunction

endscope

Good luck.

I know I didn't used to but an initializer on scopes. Is it only for this type of trigger, or what?

 

[PurgeandFire]

Yeah, it used to require you to use:
public function InitTrig takes nothing returns nothing

I'm not sure if that works still, it might.

But basically, initializers just allow you to declare any function you want to be called upon map initialization. It works on any kind of trigger/scope.

EDIT: Yeah, using public function InitTrig takes nothing returns nothing still works. It is just a choice of preference. Most people ditched using that, I guess they like typing "Init" more than InitTrig. Anyway, it is the same thing for the scope. It just helps to have initializers if you want more than one scope (with initializers) in a trigger. It is the same efficiency-wise though.

Using structs, that function name becomes a simple name "onInit" that also does not require any "initializer" declaration.

Same with Zinc, but Zinc is so pro that there is a lot of good things I can say about it.

 

[PurgeandFire]

Using structs, that function name becomes a simple name "onInit" that also does not require any "initializer" declaration.

Still:

scope initializer > library initializer (and onInit)

Scope initializer == function call
library initializer == ExecuteFunc()

 

[Bribe]

Zinc doesn't have scopes/readonly

 

[Blue_Jeans]

When I would use the timer, the map freezes. My final solution was to add the initializer and directly call Actions inside of the InitTrig.

I'm done with this thread, but could you send me a link for Zinc?

 

[Bribe]

In my sig I link the Zinc manual, and it comes automatically with JassHelper 0.A.2.B

How do you check to see if a player is controlled by a guy in front of the computer?
