==Another example== | |||
A custom object is something that you create that has [[Properties|properties]] like the other ROBLOX objects, such as game.Workspace.Brick.Transparency | |||
===Declaring an object=== | |||
Your data type here will be a "Vector2". | |||
<code lua>Vector2 = {} --this declares the class "Vector2"</code> | |||
<code lua> | |||
function Vector2.new(one, two) --the function that we will use to create new objects of this class | |||
newTB = {x, y} --this makes our new object with the properties, which you set as objects in the table | |||
newTB.x = one --set the value to the one called in the argument | |||
newTB.y = two | |||
return newTB | |||
end | |||
</code> | |||
Now, we can call a new object of the class as such: | |||
<code lua> | |||
a = Vector2.new(7, 8) | |||
print(a.x) --> 7 | |||
print(a.y) --> 8 | |||
a.x = 10 | |||
print(a.x) --> 10 | |||
</code> | |||
===Adding member functions to your object=== | |||
<code lua> | |||
function Vector2.new(one, two) | |||
newTB = {x, y} | |||
newTB.x = one | |||
newTB.y = two | |||
function newTB.reset() | |||
newTB.x = 0 | |||
newTB.y = 0 | |||
end | |||
return newTB | |||
end | |||
a = Vector2.new(5, 8) | |||
print(a.x) --> 5 | |||
print(a.y) --> 8 | |||
a:reset() | |||
print(a.x) --> 0 | |||
print(a.y) --> 0 | |||
</code> | |||
