-- API - registers an effect
|
|
-- required parameters in def:
|
|
-- name - string - effect name in code
|
|
-- description - translated string - actual effect name in game
|
|
-- optional parameters in def:
|
|
-- get_tt - function(factor) - returns tooltip description text for use with potions
|
|
-- icon - string - file name of the effect icon in HUD - defaults to one based on name
|
|
-- res_condition - function(object) - returning true if target is to be resistant to the effect
|
|
-- on_start - function(object, factor) - called when dealing the effect
|
|
-- on_load - function(object, factor) - called on_joinplayer and on_activate
|
|
-- on_step - function(dtime, object, factor, duration) - running every step for all objects with this effect
|
|
-- on_hit_timer - function(object, factor, duration) - if defined runs a hit_timer depending on timer_uses_factor value
|
|
-- on_end - function(object) - called when the effect wears off
|
|
-- after_end - function(object) - called when the effect wears off, after purging the data of the effect
|
|
-- on_save_effect - function(object - called when the effect is to be serialized for saving (supposed to do cleanup)
|
|
-- particle_color - string - colorstring for particles - defaults to #3000EE
|
|
-- uses_factor - bool - whether factor affects the effect
|
|
-- lvl1_factor - number - factor for lvl1 effect - defaults to 1 if uses_factor
|
|
-- lvl2_factor - number - factor for lvl2 effect - defaults to 2 if uses_factor
|
|
-- timer_uses_factor - bool - whether hit_timer uses factor (uses_factor must be true) or a constant value (hit_timer_step must be defined)
|
|
-- hit_timer_step - float - interval between hit_timer hits
|
|
-- damage_modifier - string - damage flag of which damage is changed as defined by modifier_func, pass empty string for all damage
|
|
-- dmg_mod_is_type - bool - damage_modifier string is used as type instead of flag of damage, defaults to false
|
|
-- modifier_func - function(damage, effect_vals) - see damage_modifier, if not defined damage_modifier defaults to 100% resistance
|
|
-- modifier_priority - integer - priority passed when registering damage_modifier - defaults to -50
|
|
-- affects_item_speed - table
|
|
-- -- if provided, effect gets added to the item_speed_effects table, this should be true if the effect affects item speeds,
|
|
-- -- otherwise it won't work properly with other such effects (like haste and fatigue)
|
|
-- -- -- factor_is_positive - bool - whether values of factor between 0 and 1 should be considered +factor% or speed multiplier
|
|
-- -- -- - obviously +factor% is positive and speed multiplier is negative interpretation
|
|
-- -- -- - values of factor higher than 1 will have a positive effect regardless
|
|
-- -- -- - values of factor lower than 0 will have a negative effect regardless
