Re: Urgent help with Bioshock FPS and Weld Animation

I have a system for my FPS:

There is a script that will constantly weld arms to a screen. It can move and rotate those arms based on two values, RIGHT/LEFT Arm Position and Rotation (RAP, RAR, LAP, LAR).

In my gun script, I made a function that will clone a script that will execute a bit of code in a StringValue called sourc. Sourc will be set by the gun script as follows:

------------------------------------------------------------

function RunCoding(code)
if code then
clone = ScriptsGroup.zzzGUIDEzzz.RunScript:Clone()
clone.Parent = script
clone.Name = "CodeGo"
Sourc = Instance.new("StringValue", clone)
Sourc.Name = "Sourc"
Sourc.Value = code
clone.Disabled = false
return clone
end
end

function OnFire()

blabla gunstuff

--STOP ANIMATION HERE
if CoroutinesSk then
CoroutinesSk.Disabled = true
CoroutinesSk:Destroy()
RAP = RAP
end

--start anim here
local CoroutinesSk = RunCoding([[
print("doin it")
MyPlayer = game.Players.LocalPlayer
ScriptsGroup = MyPlayer.PlayerGui.Scripts

local LAR = ScriptsGroup.ArmsFollowScreen.LeftArmRotation.Value
local LAP = ScriptsGroup.ArmsFollowScreen.LeftArmPosition.Value
local RAR = ScriptsGroup.ArmsFollowScreen.RightArmRotation.Value
local RAP = ScriptsGroup.ArmsFollowScreen.RightArmPosition.Value
local RAPP = ScriptsGroup.ArmsFollowScreen.RightArmPosition.Value

for i=1, 3 do
wait(.1)
RAP = RAP - Vector3.new(0,0,.1)
end
print("SHOOTING ANIMATION HALF WAY THROUGH: " .. tostring(RAP))
for i=1, 3 do
wait(.1)
RAP = RAP + Vector3.new(0,0,.1)
end
RAP = RAPP
print("DONE")
script:Destroy() --haha
]])

blabla gunstuff

end

---------------------------------------------------------------

This allows it to simulate coroutines. I have a problem though. The above script is supposed to be a recoil script. When I shoot it, the arm doesn't even move. Not one bit. Why is this happening?

Also, what's this?

'blabla gunstuff'

Also, blabla gunstuff is essentially the bullet, the takedamage, the recoil spread, the flash, etc. Not really required for the post.

From a glance of the script it resets RAP

Although thats pointless with the introduction of local variables

Allow me to clarify. RAP is actually defined in the gun script ABOVE the functions. Thus, when I state RAP = RAP, it takes the value that it last has of RAP (which is the original) and makes that the value of RAP (Right Arm Position). It resets it.

The value of RAP in the gun script isn't changed at all by any code in CoroutinesSk, as that is merely a string to be executed in another script.

But still, it doesn't explain the problem - why does the animation not show?

BUUUMP.

Idea: Maybe it's because it takes too long to create a script with the StringValue and Enable it?

Not deciphering your code, your problem is probably scope. I don't know for sure exactly what the precedence is, but if you have something like this:

local RAP = whatever

...bluh...

function(RAP)
RAP = RAP --whut
end


change one of the variables' names to avoid the ambiguity.

Alright, but that still doesn't explain why the second script isn't producing the animation.

I'm thinking of perhaps getting rid of the entire secondary script method and using a normal coroutine, but I would need some way to kill it outside of the coroutine, which I haven't found yet.

@OP
From the title, it looks like you want us to prioritise this over helping others... why? What makes this any more important than helping someone with a simple function which breaks the joints of a character?

Well, Vector, if you want to go help someone else first, go do it by all means. I came here because it said "Scripting Helpers." I didn't come here to be asked insulting questions.

So if you would rather ask me why I worded a title the way I did than help me fix my problem, then I guess I'll just have to try and fix this myself.

So much for Scripting "Helpers."

If you think that was an insulting question, then you've no idea about the *other* sub-forums.
You're right, the name of the sub-forum is "Scripting Helpers", but not one place does it, nor should it, say that one person should be prioritised over another. I will return to my initial question.

@Vrakner; for the most part you can ignore the snobs around here. Most of us try to be helpful, but there's only so much a few users can do.

Also, it's not exactly prime time for American users, which encompasses the majority of ROBLOX's playerbase. The only reason I'm awake is because I never sleep. :>

What I suggest you trying is using Welds to animate everything. You'll only have to animate relative to a 'fixed' object, like the Character's Torso, and edit the C1 property of the weld, and it'll work everywhere.

@adark
Perhaps that was just my misinterpretation, but did that sentence superiorise American users over others? I wouldn't be surprised if I did misinterpret it; it is pretty late over here.

@Vector; I mean no insult when I say you need to take a chill pill man. All I stated was that it is pretty late/early in America, where the majority of ROBLOX's players reside. It's 4 AM central time, so most people in the US are asleep right now.

Well, technically that is what I'm doing. I have a separate script that uses Welds to weld the arms to point where the mouse is pointing, and I can adjust the CFrame of the welds using RAP, RAR, LAP, LAR (the position and rotation of the welds).

I was thinking the problem may be that the secondary script I'm making to adjust RAP, RAR, etc. may take too long to load, but that idea doesn't make sense since the output from the secondary script is correct. (doin it, done, etc.)

Describe for me in detail how your script is supposed to run. I don't want lines of code, just an explanation, I.e. Touch a lava brick -> kill player.


Go through your code as you explain its process, and see if you find anything that doesn't make sense. If this doesn't help ya, I'll point out any logic mistakes you may have made, or write out the method currently forming in my mind.
