Spawning a unit in 2 scenarios later based on a choice

[tribes55]

Didn't really know what to put in the subject line.

So, in one of my scenarios you can choose 4 units out of a total of eight units to accompany you in the following scenarios.
Two scenarios later, I spawn in the units that you didn't pick to help defend.

But it's not working; they are not spawning, and I don't know why.

Here is an example of what I have for one of the units:

Scenario 3 (Where you pick the units) I did not include the entire event as it is large.

Spoiler:

Code: Select all

[event]
	name=moveto
	[filter]
		id=Gandfal
		[filter_location]
			[filter]
			id=Harlar
			[/filter]
			radius=1
		[/filter_location]
	[/filter]
	[if]
		[variable]
			name=count_done
			equals=1
		[/variable]
		[then]
			[message]
				speaker=Gandfal
				message= _ "We have enough people. I think it's time we move on North to investigate."
			[/message]
			[set_variable]
				name=harlarvar
				value=1
			[/set_variable]	
		[/then]
		[else]
	[message]
		speaker=Harlar
		message= _ "..."
	[/message]
	[message]
		speaker=Gandfal
		message= _ "Hey Harlar... "
		[option]
				label= _ "Recruit Harlar"
			[command]
			[message]
				speaker=Gandfal
				message= _ "I need some men to go investigate the North Gate. You're experienced, a great warrior, if not a bit quiet."
			[/message]		
			[message]
				speaker=Harlar
				message= _ "..."
			[/message]
			[modify_unit]
				[filter]
					id=Harlar
				[/filter]
					side=1
			[/modify_unit]
			[set_variable]
				name=harlarvar
				value=2
			[/set_variable]	
			[fire_event]
				name=count_units
			[/fire_event]
			[/command]
		[/option]
[/event]		

So that event makes it where the variable is set to 2 if you choose him. Otherwise, it is set to one. I also set the variable to one at the start of the scenario, so it's rather redundant, but it's there for the sake of testing.

Two scenarios later, I do a check and attempt to spawn in the unit.

Code: Select all

[event]
	name=harlarvar
[if]
	[variable]
		name=harlarvar
		equals=1
	[/variable]
	[then]
	{NAMED_UNIT 4 "Dwarvish Steelclad" 13 9 Harlar "Harlar the Quiet" hitpoints=38}
	[/then]
[/if]
[/event]

But he doesn't spawn, despite the variable's value being 1. Nothing happens.
So to recap: I want the units that aren't picked to spawn in two scenarios later. I do this by assigning variable's value to 1 if they're not picked, and 2 if they're picked. Two scenarios later, I check if the value is 1. If it's one, I attempt to create the unit, but it doesn't work.

Thanks!

Do you mean equals=1 instead of value=1?

Oh yes, I did. I have made the adjustment to the second part, I think that's all that's necessary to make since the first part isn't conditional around the variable.
But it still doesn't work.

Are you sure the event in the later scenario is triggering? It has name=harlarvar, but I'd expect name=start or name=turn 1.

BTW, you don't need conditional code, you can just store an array of units in a variable with [store_unit] and unstore them in a later scenario, which means you only need to put their stats in the first scenario.

[tribes55]

Yeah, I figured a work-around would be to switch their sides via [modify_unit], then store them. Then I suppose I could recall and then modify their side again, but that seems pretty duct-tapey. I don't want them to be owned by player one.

Edit:

I tried including it all in the start event (excluding the event tags of the original code, and their respective names) and it still did not work.

[octalot]

Split the problem in to smaller ones - put a [message] in the event, and check that the event triggers. Then put some debugging in to the message, or use an [inspect] tag, to check the values of the variables just before it fails.

They don't need to be owned by side 1 to be stored in a variable (although you would still have to switch the side number if it was a different side in the second scenario).
