How does one use variables in standard table.maxn or similar functions?
I for example have a table called “maps”:
- local maps
- {
- “map_a”,
- “map_b”,
- }
I do then retrieve an element at random (at index 1 in the example) from the table “maps” and save it in a variable called “currentmap”:
- local currentmap = table.concat(maps, “”,1, 1 )
I have two more tables, one for each map:
- local map_a
- {
- “positon_aa”,
- “positon_ab”,
- }
- local map_b
- {
- “positon_ba”,
- “positon_bb”,
- }
Finally i want to calculate the number of elements in the table using table.maxn in combination with the “currentmap”-variable and save it in another variable called “positions” for further computations:
- local positions = table.maxn(currentmap)
When compiling it shows an error and says table.maxn is met with a string where a table was expected.
The problem is that my first table “maps” is containing strings, but these strings are also the name of a table.
How would i go about telling the programm to look for the string as a tablename or insert the elements as variables into the “maps”-table if that makes any sense?
When answering please keep in mind that this was just a simplified example.
If at all possible i need to “automate” the table.maxn and/or table.concat commands to the point where i don’t have to hardcode every possibility.
Thanks in advance
