ModuleScript.Source won't write string

Help and Feedback Scripting Support
#1

I’m experiencing with the BitBuffer module from:

https://dekkonot.github.io/bitbuffer/ / BitBuffer Documentation

And I tried to write the example use (found on Writing - BitBuffer Documentation) with kind of success, but it won’t let me write it to a ModuleScript source. This is basically the script:

local data = {
	name = "John Doe",
	health = 100,
	maxHealth = 100,
	points = 10,
	position = {
		x = 10.55915,
		y = -15.2222,
	},
	bossesKilled = { true, false, true },
}

local BitBuffer = require(game.ServerStorage.BitBuffer) -- The BitBuffer should be required here.

local buffer = BitBuffer()

buffer.writeString(data.name)
buffer.writeUInt16(data.health) -- This is assuming someone's health will get above 255 but stay below 32,767
buffer.writeUInt16(data.maxHealth)
buffer.writeUInt16(data.points) -- Also assuming someone's points will stay rather low
buffer.writeFloat32(data.position.x)
buffer.writeFloat32(data.position.y)
buffer.writeField(table.unpack(data.bossesKilled))

-- To do the math: 11 bytes for name (length prefix + raw bytes), 2 each for health, maxHealth, and points, 
-- 8 for position, and an extra 1 for bossesKilled (though you could write 5 more bools without loosing any space!). 
-- 11+6+8+1 = 26

local output = buffer.dumpString()

local bv = Instance.new("ModuleScript")
bv.Parent = game.ServerStorage
bv.Name = "Compiled?"

bv.Source = output

I’m running this code from the command bar. When I print:

print(output)

It does show me the compiled output string:

But the module script just remains empty.

Does anyone know why this is? I’ve seen multiple people work with BitBuffer so I don’t really understand why this doesn’t function correctly for me.

Thanks for the reply!

Have you tried string.pack and string.unpack? Those work pretty well over the BitBuffer module.

Edit: oh, I thought you were using an older version.

I’m executing from the command bar, if that is what you are referring to.

#5

But you’re assigning a string to the source attribute in the script, aren’t you?

#6

Yeah I’m assigning the Source attribute of the script.

#7

If I would insert any string, it would insert it into the source, but the bitbuffer output doesnt, thats the main issue

#8

You can’t insert into the source from another script, you can only do that from command bar and plugins.

#9

I have a gut feeling that he knows.

#10

The only issue I’m having is that it doesnt put the BitBuffer output in the script.

#11

If you check what is the first character of the output string, for example by using

print(string.byte(output))

you will notice that it has the ascii code 0, which is a Null character, or “\0”. It is used in a string to show where it ends, that is why, when you assign that output to the Source attribute - your module will be empty.

You can try:

module.Source = "test1 \0 test2"

And in your module you will only have “test1”, because Roblox treats “\0” as an ending of a string, therefore it doesn’t read anything beyond that.
