Solarus 1.6 Tutorial [en] - #50: Metatables
8How to program a global behavior of all objects of the same type without duplicating the code? Metatables, a very powerful Lua feature, are an elegant answer to that problem.
The metatable of a type specifies the shared behavior of all objects of this type. When you assign a function to the metatable of a type, everything is like if all objects of that type had this function.
You can for instance define a default event on the sensor type instead of having to search for every sensor instance.
