Advancement Effect apply_to=bonus_attack

[hyper_cubed]

I was perusing through Dugi's codebase for legend of the invincibles and found an advancement called arrow storm. I would like to do something similar, and have already instantiated the weapon special, but there is something that I cannot account for. As I search the database for "bonus_attack" in the context of [effect] I return no information.

Has anyone used a similar context modifier for [effect]?

Code: Select all

        [advancement]
            max_times=1
            always_display=yes
            id=arrowstorm
            description= _ "able to shoot a storm on arrows without giving the enemy a chance to counterattack"
            image=attacks/bow-elven-magic.png
            strict_amla=yes
            require_amla=""
            [effect]
                apply_to=bonus_attack
                name=arrow storm
                description= _ "arrow storm"
                icon=attacks/bow-elven-magic.png
                range=ranged
                defense_weight=0
                damage=-20
                number=-40
				clone_anim=yes
                [specials]
                    {WEAPON_SPECIAL_DISTANT_ATTACK}
                [/specials]
            [/effect]
            {AMLA_DEFAULT_BONUSES}
        [/advancement]

Given that damage and number is negative, this is only input for his code that creates such attack.

[Celtic_Minstrel]

Perhaps Dugi is using the feature new to 1.13.x that allows you to define custom values for [effect]apply_to= using Lua. See here for details of how to do that.

[The_Gnat]

I don't know what Dugi's effect does but perhaps you could use apply_to=new_attack.

That allows you to create a new attack when the unit advances, perhaps it is of some use?

iirc dugis addons implementes this type of effect manually in postadvance etc events, although it could also be implemented via the new 1.13 custom effects. One important different between duigs implementation and a possible 1.13 custom effect implementation is that dugis implementatiojn makes sure the bonus_attack effects are always applied last so that effect modifying the original attack will also effect an eariler bonus_attack

Hey so I figured out how dugis is doing it.

It is not a native functionality of Wesnoth, instead he is adding tags for post addition events as the last poster suggested. I wrote up my own code that will clone animations given that you can provide the unit_type, gender, attack_name, and the attack_name that you want to apply it to.

Dugi's code does it from Legend_of_the_Invincibles\utils\stats.cfg (about half way down ctrl + f "bonus_attack" will take you to it.

Here is what I came up with (I prefixed the names with _0 because I wanted to be able to clone multiple existing attacks)

Code: Select all

#define clone_anim_0 unit_type gender attack_id apply_to
[store_unit_type]
    type={unit_type}
	variable=unit_type
[/store_unit_type]
[if]
	[variable]
		name={gender}
		equals="male"
	[/variable]
	[then]
		{VARIABLE idx_1 0}
		[while]
			[variable]
				name="idx_1"
				less_than=$unit_type.attack_anim.length
			[/variable]
			[do]
				[if]
					[variable]
						name=unit_type.attack_anim[$idx_1].filter_attack.name
						equals={attack_id}
					[/variable]
					[then]
						[set_variables]
							name=grab_anim
							mode=append
							[value]
								apply_to=new_animation
								name={apply_to}
								[insert_tag]
									name=attack_anim
									variable=unit_type.attack_anim[$idx_1]
								[/insert_tag]
							[/value]
						[/set_variables]
						[set_variables]
							name=grab_anim.attack_anim[$idx_1].filter_attack
							mode=merge
							[value]
								__remove=yes
							[/value]
						[/set_variables]
						#{VARIABLE grab_anim.attack_anim[$idx_1].filter_attack.name "$empty"}
					[/then]
				[/if]
			{VARIABLE_OP idx_1 add 1}
			[/do]
		[/while]
		{CLEAR_VARIABLE idx_1}
		[set_variables]
			name=clone_anim_0
			mode=append
			to_variable=grab_anim
		[/set_variables]
		{CLEAR_VARIABLE unit_type}
		{CLEAR_VARIABLE grab_anim}
	[/then]
[/if]
[if]
	[variable]
		name={gender}
		equals="female"
	[/variable]
	[then]
		{VARIABLE idx_1 0}
		[while]
			[variable]
				name="idx_1"
				less_than=$unit_type.female.attack_anim.length
			[/variable]
			[do]
				[if]
					[variable]
						name=unit_type.female.attack_anim[$idx_1].filter_attack.name
						equals={attack_id}
					[/variable]
					[then]
						[set_variables]
							name=grab_anim
							mode=append
							[value]
								apply_to=new_animation
								name={apply_to}
								[insert_tag]
									name=attack_anim
									variable=unit_type.female.attack_anim[$idx_1]
								[/insert_tag]
							[/value]
						[/set_variables]
						[set_variables]
							name=grab_anim.female.attack_anim[$idx_1].filter_attack
							mode=merge
							[value]
								__remove=yes
							[/value]
						[/set_variables]
						#{VARIABLE grab_anim.female.attack_anim[$idx_1].filter_attack.name "$empty"}
					[/then]
				[/if]
			{VARIABLE_OP idx_1 add 1}
			[/do]
		[/while]
		{CLEAR_VARIABLE idx_1}
		[set_variables]
			name=clone_anim_0
			mode=append
			to_variable=grab_anim
		[/set_variables]
		{CLEAR_VARIABLE unit_type}
		{CLEAR_VARIABLE grab_anim}
	[/then]
[/if]
#enddef
#define clear_clone_anim_0
{CLEAR_VARIABLE clone_anim_0}
#enddef

and then when you want to implement it you just insert the clone_anim_0 variable as an effect to an existing attack.... easy mode from there.
call (note that a good deal of my weapon data was generated by pre-made queries so you wont see alot of hard coded values):

Code: Select all

{clone_anim_0 $unit.type unit.gender $attack_id "avatar"}
....do things
[advancement]
					id=dwarf_0
					always_display=yes
					description={desc_dwarf}
					image={img_race_dwarf}
					max_times=1
					strict_amla=yes
					require_amla=""
					[effect]
						apply_to=resistance
						[resistance]
							blade=-14
							impact=-12
							pierce=-4
						[/resistance]
					[/effect]
					[effect]
						apply_to=new_attack
						name=avatar
						description= _ "avatar"
						icon=Attacks/Melee_Avatar.png
						accuracy=-95
						type=$attack_type
						range=$attack_range
						damage=$mod_damage_0
						number=$mod_number_0
						[specials]
							{WEAPON_SPECIAL_CHARGE}
						[/specials]
					[/effect]
					[insert_tag]
						name=effect
						variable=clone_anim_0
					[/insert_tag]
					.....do more things
					{clear_clone_anim_0}
