Collider:on_uncollide

Called when a collider or sensor stops colliding with this collider. Default implementation does nothing.

Usage

collider.on_uncollide = function(self, other_component, other_entity, contact)
  -- your code here
end

Arguments

Name	Type	Description
other_component	Collider or Sensor	Components this collider was overlapping with.
other_entity	Entity	Entity no longer being collided, owner of other_component.
contact	love.Contact	Contact generated by the collision.

As the LOVE documentation recommends:

The lifetimes of Contacts are short. When you receive them in callbacks, they may be destroyed immediately after the callback returns. Cache their values instead of storing Contacts directly.

Examples

local ecs = crystal.ECS:new();
ecs:add_system(crystal.PhysicsSystem);

local hero = ecs:spawn(crystal.Entity);
hero:add_component(crystal.Body);
local collider = hero:add_component(crystal.Collider, love.physics.newCircleShape(4));
hero:set_categories("characters");
hero:enable_collision_with("level", "characters");

collider.on_collide = function(self, other_component, other_entity, contact)
  print("Bonking against " .. tostring(other_entity));
end

collider.on_uncollide = function(self, other_component, other_entity, contact)
  print("No longer bonking against " .. tostring(other_entity));
end
