table dimensioning...

[phipslk]

I want to initialize a table that looks like this:

player[number].row[number].x=100
player[number].row[number].y=199

but I get errors, if I do

player={}

and then add values like

player[1].row[2].x=100

anyone who can point me to my error? better to use dim? but how?

thats because you can have table inside table (multidimensional tables) but tables are anonymous, only pointing by its position

check this, simulates what you want creating 3 player with 3 "rows" and x and y to each "row"
just keep in mind that "row" is the second dimension

Code: Select all

Dim player[2]
For i=0 To 2
	player[i]= {{x=i+10,y=i+20} , {x=i+30,y=i+40} , {x=i+50,y=i+60}}
Next
DebugPrint(player[0][0].y)
DebugPrint(player[0][0].x)
DebugPrint("Now see entire table how it looks")
DebugPrint(SerializeTable(player))

Plouf explained correctly, but might be easier to understand it this way.

The point here is that you can't just make Table = {} and then use something like Table.x{1].sub[2], because you have not made any tables beyond "table", as in Table.x doesn't exist yet, you have to first do it using Table.x = {}

However, if you start by directly doing Table.x = {}, without doing table = {} first, then it would fail again, since Table wouldn't exist yet.

To show the easier-to-understand way how your case would work is to do:

Code: Select all

Player = {}
Player[1] = {}
Player[1].Row = {}
Player[1].Row[1] = {x = 100, y=199}

Now you can use:

Code: Select all

Player[1].Row[1].x = 200
Player[1].Row[1].y = 300

But do realize that Player[2] or player[3] doesn't exist yet, neither do Player[1].Row[2], or Player[1].Row[3] exist yet, you have to make them into existence too, which you could do, for example, in the following way (easier to understand way perhaps)

Code: Select all

Player = {}
for p = 1 to 4
	Player[p] = {}
	Player[p].Row = {}
	for r = 1 to 10
		Player[p].Row[r] = {X = 1, Y = 2}
	next
next

Now you would have players 1-4, and each of them contains rows 1-10, with X and Y inside that table

cool, thank you both! I think I got it now.
