Why is this array saying there is nothing inside when there is?
1 | healList[v.UserId] = healBeam |
2 | for i,v in pairs(healList)do |
3 | print(v.Name) -- prints UserId of player |
4 | end |
5 | print(#healList) -- prints 0 |
The array has something inside as it printed out the UserId of the player, yet it says there is nothing in the array. Can anyone help me understand why this is happening?

The length operator doesn't actually count the number of elements in an array. It finds the largest consecutive index starting at 1. This means that:
1 | local array = {} |
2 | array[2] = 2 |
3 | array[3] = 3 |
4 | print(#array) -- will print 0, since array[1] is nil |
You are using UserIds, which of course would not be consecutive. To properly count the elements in your array:
1 | local count = 0 |
2 | for _,_ in pairs(healList) do |
3 | count = count + 1 |
4 | end |
5 | print(count) -- correct number of keys |
