crystal.Drawable

A base Component for anything that can draw on the screen.

This base class is of little use without overriding the draw() method.

Constructor

Like all other components, Drawable components are created by calling Entity:add_component.

The constructor for Drawable expects no arguments.

Methods

draw	Draws the component. Default implementation does nothing.
draw_offset	Returns the offset to use when drawing this drawable.
draw_order	Returns the draw order of this Drawable.
set_draw_offset	Sets the offset to use when drawing this drawable.
set_draw_order_modifier	Sets how the draw order of this Drawable is computed.

local entity = ecs:spawn(crystal.Entity);
local drawable = entity:add_component(crystal.Drawable);
drawable.draw = function(self)
  love.graphics.rectangle("fill", 20, 50, 60, 120);
end
