DroppableItem

This page is for code fragments for dropping items.

Droppable on Death

This section is for macros that drop an item due to the death of unit.

Dropping a picked up item

This macro comes in two parts with space for [effect] code between them. Using this macro creates an item at a point on the map specified by X and Y, keeps track of it (when the unit carrying it dies) via two variable (which the user names!!) and provides an image for the map.

Note that if you want any unit to be able to pick up the item you can ignore the ADDITIONAL_FILTERS part.

Part One

#define DROPPABLE_ITEM X Y XVAR YVAR NAME IMAGE ADDITIONAL_FILTERS
[label]
x={X}
y={Y}
text="{NAME}"
[/label]
[event]
name=prestart
	{VARIABLE {XVAR} {X}}
	{VARIABLE {YVAR} {Y}}

	[item]
	x=${XVAR}
	y=${YVAR}
	image={IMAGE}
	[/item]
		
	[event]
	name=die
	first_time_only=no
	[store_unit]
	[filter]
	x=$x1
	y=$y1
	[/filter]
	variable=itemstore
	[/store_unit]
	[if]
	[variable]
	name=itemstore.variables.{XVAR}
	equals=on
	[/variable]
		[then]
		{VARIABLE_OP {XVAR} to_variable x1}
		{VARIABLE_OP {YVAR} to_variable y1}
		[item]
		x=$x1
		y=$y1
		image={IMAGE}
		[/item]
		[/then]
	[/if]
	[/event]

	[event]
	name=moveto
	first_time_only=no
		[filter]
		x=${XVAR}
		y=${YVAR}
		{ADDITIONAL_FILTERS}
		[/filter]
		
		[removeitem]
		x=${XVAR}
		y=${YVAR}
		[/removeitem]
		[store_unit]
		variable=itemstore
		[filter]
		x=${XVAR}
		y=${YVAR}
		[/filter]
		[/store_unit]
		{VARIABLE itemstore.variables.{XVAR} on}
		[unstore_unit]
		variable=itemstore
		[/unstore_unit]
		
		[unit_overlay]
		x=${XVAR}
		y=${YVAR}
		image={IMAGE}
		[/unit_overlay]
		
		[object]
		name={NAME}
		image={IMAGE}
		duration=forever
		cannot_use_message="-cannot use message-"
			[filter]
			x=${XVAR}
			y=${YVAR}
			[/filter]
#enddef

Effect goes here

Of course the code for the macro above will do nothing without an [effect] attatched to the item (via the [object] tag in the above macro) other than cart an image around. To add an effect, make an [effect] tag as below (or look at EffectWML:

#All this should be between the usage of the DROPPABLE_ITEM macro and its /DROPPABLE_ITEM
#		
# This is not the only thing you can do but for an item that increases movementspeed by 10(!) do:
[effect]
    apply_to=movement
    increase=10
[/effect]

Part 2

Once you have done all of the above, call the closing macro to close all the tags and clear the variables.

#define /DROPPABLE_ITEM XVAR YVAR
		[/object]
		
	{VARIABLE {XVAR} 0}
	{VARIABLE {YVAR} 0}
	[/event]
[/event]
#enddef

Dropping Loot

This macro makes it so that when a unit matching a filter dies, it will drop an item (eg gold!)

#Re writing... come back later.
