This is a custom game that I made and I am looking for suggestions to better the game and/or condense the code. Thanks.

@JackMoody3 You need to learn about tables. That will cut the size of your code and make it easier to add to.

@dave1707 I agree, what is a good resource for learning about tables?

4

Tap on the “Wiki” option under Codea Talk at the top of the forum. A there are a lot of tutorials there.

Okay, thankyou

@JackMoody3

Tables aren’t that hard, just think of them as a way of storing multiple values:

x = {"Hello ", "World!"}
print(x[1])

So x is the table, and to get the nth index of that table you use [n] after the table.

I’m pretty sure you can store any values in a table.

There are two different ways you can use tables, as arrays, or as dictionaries.

In an array you can basically do what I did above:

x = {1, 2, 3, 4}

Remember how you would say [n] to get the nth value of the array? In a dictionary you can control the indexes:

x = {["Hello"] = "Hi ", ["Earth"] = "World!"}

Which can also be shortened with some syntactic sugar:

x = {Hello = "Hi ", Earth = "World!"}

Thank you Lua :smiley:

So then you can do this:

print(x["Hello"])

Or some more syntactic sugar!

print(x.Hello)

You can also create new indexes after you make the table in 3 ways:

x[n] = "Hello"
table.insert(x, n, "Hello")
rawset(x, n, Hello)

Aside from that Lua provides a whole table of different functionalities (we’ve already used one before)

The table is literally called just that, table.

Here’s a few main ones:

table.insert
table.remove
table.unpack

Another important note to remember, is that tables are stored by reference not by value:

x = {}
y = x
--Any changes to x or y will change the other:
x[1] = "Hi"
print(y[1])
--> Hi

Looping through a table COULD be done with a normal for loop:

x = {"Hi ", "Planet ", "Earth"}
for I = 1,#x do
print(x[I])
end

Or with pairs/ipairs:

for I,v in pairs(x) do
print(v)
end

Important note: #x won’t work if x is a dictionary!

In the generic for loop used above, I is the index, v is the value.

Difference between pairs and pairs:

pairs: Ignores nil Indexes

ipairs: Stops at the first nil index it finds

If you have any questions don’t hesitate to PM me!

You can also just think of a 1d array as a matrix. They are actually sort of simpler then matrixes.
