Call function with variable (using AeroGameFramework)

Help and Feedback Scripting Support
#1

I am using Crazyman32’s AeroGameFramework, and I am creating a round based game. I am trying to call a function that is identified in the :Start() area of the round service with a string stored in a variable.
Here is the code I tried:

local event = events[math.random(1,#events)]
[event](player)

“events” is a table containing 4 strings, and each function is named after each string in the table.
I get the error ServerStorage.Aero.Services.RoundService:54: attempt to call a nil value

How do I call the function using the string stored in the variable “event”?

I don’t think you would need the square brackets on the second line:

local event=events[math.random(1,#events)]
event(player)

Not sure if that would work if it’s a string in the table, maybe?

I removed the square brackets, however I got the same error.
14:26:39.956 - ServerStorage.Aero.Services.RoundService:63: attempt to call a string value
(Different line because I added code above that block in the script)

#5

Can you show us what the events variable is?

#6

Just a table full of strings.

local events = {"Die","ColorPlate","Explode","Slow"}
#7

Well that’s your issue. You’re literally trying to call a string value. Let’s say the result of math.random(1, #events) ends up being 3 then what the event variable ends up being is "Explode".

Do you have a folder in ServerStorage or ReplicatedStorage which has all your RemoteEvents?

#8

Yes, and then that’s my question. How do I use a string value to call a function named the same thing as the value of the string?

This is all in a ServerScript created with AeroGameFramework, and I have no events besides one that updates the status bar at the top of the screen (a text label)

#9

Are your events such as “Slow” inside that same script or is it a global function?

#10

You should store the functions themselves in the table, not strings.

What you’re asking isn’t possible by any practical means.

#12

Can you possibly show us your entire script or provide an .rbxl? You can’t call a function by string.

“events” is simply the table name, not the actual object. They are all functions specified in the script.

#14

I can try to just store the functions in the table itself, instead of strings.

Yes we get that,but when you do #events your counting everything inside the table and going by 1 to the number of things in the table and selecting 1 thing at random

#17

What is your goal with this system in the first place? Are you trying to randomly pick a function and run it?

Yes, that is what I’m trying to do.

Because a data store is irrelevant here. OP isn’t trying to store data that is persistent through game sessions.

Technically you could call a function if it was _G, but since this is all in the same script I dont think it would be possible.

heres how you can link your functions into the events table

local events = {}
events.Explode = function ()
	-- Code here
end

It sounds like an event system for a minigame where something random happens to a player and he is trying to randomize what happens.

Here is an example that would work for randomizing events (this is a module per event basis as it would become more organized than having every event inside a table):
Example.rbxl (15.3 KB)

@helperobc’s method would work as well though.

I tried using this, however I get the interval empty error.

How do I get a random function from this example?
