Hey, so I coded this custom entity that's a lot like the iron ball from A Link to the Past's Eagle Tower- it's an object the hero can pick up and throw, and then pick up again and keep on throwing. You can even carry it to other maps and keep smashing it into enemies faces. I can it "toss_ball", haha.
You can set the properties "weight" and "damage" on the custom entity, which by default are 1 and 6. When this entity hits an enemy, it'll try to call enemy:hit_by_toss_ball() , so if you want certain enemies to exhibit different behavior on being hit by this than being damaged, define that function for those enemies (if, for example, you wanted an enemy to have its shield destroyed, or become vulnerable when hit with this or something.). Note: hit_by_toss_ball() will be called whether the hero throws the ball into the enemy, but also if the enemies runs into the entity while it's on the ground.
local entity = ...
local game = entity:get_game()
local map = entity:get_map()
local DEFAULT_DAMAGE = 6
function entity:on_created()
entity:set_traversable_by(false)
entity:set_drawn_in_y_order(true)
entity:set_follow_streams(true)
entity:set_traversable_by("enemy", true)
entity:set_weight(1)
if entity:get_property("weight") then
entity:set_weight(entity:get_property("weight"))
end
end
local enemies_touched = {}
entity:add_collision_test("sprite", function(entity, other)
if other:get_type() == "enemy" then
local enemy = other
if not enemies_touched[enemy] and enemy:hit_by_toss_ball() then
enemy:hit_by_toss_ball()
end
enemies_touched[enemy] = enemy
sol.timer.start(map, 1000, function() enemies_touched[enemy] = false end)
end
end)
function entity:on_lifting(carrier, carried_object)
carried_object:set_damage_on_enemies(game:get_value(DEFAULT_DAMAGE)
if entity:get_property("damage") then
entity:set_weight(entity:get_property("damage"))
end
carried_object:set_destruction_sound("running_obstacle")
--landing, and therefore needing to create a new toss_ball
function carried_object:on_breaking()
local x, y, layer = carried_object:get_position()
local width, height = carried_object:get_size()
local sprite = carried_object:get_sprite()
local direction = sprite:get_direction()
if carried_object:get_ground_below() == "wall" then y = y + 34 end
carried_object:get_map():create_custom_entity({
width = width, height = height, x = x, y = y, layer = layer,
direction = direction, model = "toss_ball", sprite = sprite:get_animation_set()
})
end
end
If you see any errors or mistakes I've made, please let me know so I can fix them! Have fun using this, modifying it, whatever you want.
