Why does this code return 0? How do I get it to return 1?
[code]
local spawnObjects = {OBJECT1 = {image = “images/yellowRect.png”, color = “YELLOW”}};
numSpawnObjects = table.getn(spawnObjects);
print(numSpawnObjects);

It has to do with how Lua counts keys in it’s tables.
There’s a question on StackOverflow about this very thing.

By using spawnObjects as a dictionary (rather than a list) you’re getting the weird count.
Try this:
[code]
local spawnObjects = {
{image = “images/yellowRect.png”, color = “YELLOW”},
}
– shorthand
print(#spawnObjects)
