Problem with adding variables into units and filtering them

[ZeoN_PoweR]

Hi all,

It's me again, I really find myself with poor WML skill and out of talent...

Anyway, I try to create some object to every unit who "equip" it, and I also want to add a variable on these unit for record so that I can add a filter to prevent them equip twice. This time my question is, I've tried [store_unit], [set_variable] to put a variable into these specific units, but when I use :inspect command to check them, their [variables] always shows empty. How do I access to these specific unit to store variable and make filter by their variable? Thank you.

here is my WML: (one more question, these code arrange step by step like a ladder in my UMC dev, but why after I paste them onto here, they show up in a mess??)

{VARIABLE $this_unit.variables.ironhorseshoe yes} remove $

Thanks Ravana & Sapient!!! You do solve my problem, although it still difficult for me to figure out how it works...

Here is another question with Variable.

Code: Select all

[set_menu_item]
	id=Landing_Down_{DIRECTION}
	description=_ "Landing Unit"
	[show_if]
		[have_unit]
			x,y=$x1,$y1
			side=$side_number
			ability=transport_humans
		[/have_unit]
		[have_location]
			terrain=Gg,Gs
			[filter_adjacent_location]
			x,y=$x1,$y1
			side=$side_number
			ability=transport_humans			
			adjacent={DIRECTION}
			[/filter_adjacent_location]		
		[/have_location]
	[/show_if]
	[command]

	[store_unit]
		[filter]
			x,y=$x1,$y1
			ability=transport_humans
		[/filter]
		variable=ship
	[/store_unit]
		
	[store_locations]
			terrain=Gg,Gs
			[filter_adjacent_location]
				x,y=$x1,$y1
				side=$side_number
				ability=transport_humans
				adjacent={DIRECTION}
			[/filter_adjacent_location]
		variable=landplace
	[/store_locations]
#situation1			{VARIABLE temp_x $landplace.variables_x}
#situation1			{VARIABLE temp_y $landplace.variables_y}	
--------------------
#situation2			{VARIABLE temp_x $landplace.variables.{DIRECTION}_x}
#situation2			{VARIABLE temp_y $landplace.variables.{DIRECTION}_y}
--------------------
#situation3			{VARIABLE temp_x $landplace_x}
#situation3			{VARIABLE temp_y $landplace_y}	

	[unstore_unit]
		variable=ship
	[/unstore_unit]
	
	{CLEAR_VARIABLE ship}
	{CLEAR_VARIABLE landplace}	
	{CLEAR_VARIABLE temp_x}	
	{CLEAR_VARIABLE temp_y}	
	
	[/command]
[/set_menu_item]	

When I use command [recall], I try to locate a specific landplace near my ship(x,y).
I use :inspect to look into the "x,y" of this variable landplace, and it do have the right input (x,y). But recall always end with unit appears near at my leader. How come?

Code: Select all

				[recall]
					id={target_unit_id}
					x,y=$temp_x,$temp_y
				[/recall]

[Pentarctagon]

The [recall] wiki documentation says that units are placed at those coordinates rather than next to the leader. Since you are giving an x and y coordinate and the unit is still appearing next to the leader, I would guess that $temp_x,$temp_y do not contain valid x and y coordinates.

Hi Pentarctagon,

Thanks for your explaination!!After I change WML to this, problem resolves!

Code: Select all

        {VARIABLE temp_x $landplace.x}
        {VARIABLE temp_y $landplace.y}
