Vehicle LUA Function Troubleshooting

Hello all, I have a quick question about lua that's been holding me back on my computer mod.
I have this function:
local function rainbow_Mode(COLOR_1, COLOR_2, COLOR_3, Roughness)
local objID = be:getPlayerVehicleID(0)
local veh = be:getObjectByID(objID)
local vd = extensions.core_vehicle_manager.getVehicleData(objID)
vd.config.paints = vd.config.paints or {}
local paint = createVehiclePaint({x = COLOR_1 / 1000, y = COLOR_2 / 1000, z = COLOR_3 / 1000, w=2}, {1, Roughness, 0, 0})

vd.config.paints[3] = paint
extensions.core_vehicle_manager.liveUpdateVehicleColors(objID, veh, 3, paint)

end

and I'm trying to call it within the updateGFX(dt) function using this:
local function updateGFX(dt)
if electrics.values['multicolor_input'] == 1 then
rainbow_Mode(COLOR_1, COLOR_2, COLOR_3, Roughness)
else
electrics.values['multicolor_input'] = 0
end
end

The argument local objID = be:getPlayerVehicleID(0) from the rainbow_Mode function is what I think is breaking my code. It can't seem to get the vehicle ID whatsoever.

If you need more information, ask here.

Thanks

I have no experience on 'color coding' so far but my first suggestion is to look at your IF-THEN-ELSE statement in your update function :

the ELSE statement says to shut of electrics.values.yourInput which is fine but irrelevant in this case imo. I think you've put that in to secure your statement loop (I'd understand) but the game's code will already do that cause if elec.val.inp is NOT 1 then it's already 0.
Try to leave ELSE out first and only make an ELSE statement if needed. In your case it would be a different one I guess though.

Furthermore try to print all your variables from your function to see if they are detected. Example : -- print(objID) and so on.. To actually print remove the -- and check the in-game console.

Also have you tried to declare your function to the public interface ?

-- public interface
M.rainbow_Mode(COLOR_1, COLOR_2, COLOR_3, Roughness) = rainbow_Mode(COLOR_1, COLOR_2, COLOR_3, Roughness)

Lastly I see you making (key) calls from the core files (.config.paints and extensions.core_vehicle_manager.getVehicleData)
I don't know if they work or not, I have not much experience with the color stuff so if you're sure they work then they are fine I guess.

 

I printed many of the statements, which almost all gave "nil". Printing the variable objID prints "nil", but printing the value "objID" is set to, which is be:getPlayerVehicleID(0), gives me the ID of 22441. Everything else is nil. It looks like objID can't define itself to the vehicleID number for some reason.

Declaring the local variables outside the scope just breaks the physics of the mod quicker. It just spawns nothing, as in no mesh, and no controls.

 

Did you try adding your function to the public interface as well ?

And then try to scope your vars by printing to the console ?

 

Yes for the public interface.

Yes for the public interface

What do you mean scoping my vars?

 

Beam's wiki shows very outdated or not very useful information. I took a look at this forum: https://www.beamng.com/threads/a-way-to-get-a-value-from-system-lua-t3d-lua-gameengine-lua.25139/ and tried implementing both solutions into my code, though it still returns a nil value. I'm not sure if I have to delete/change the code a certain way in order to return the correct value or not

 

So yes, I replaced my lua file with yours, and ran the obj in console, it worked, though how would I combine everything all together to make the function actually output rainbowness?

Also thank you so much

 

I don't think I'm following, though here is my MAIN lua file:

Here is the edited mod extension lua file that you gave me:

 

Oooh, it works. Thank you so much. But it doesn't randomize. How would I make it dynamically randomize the colors?

 

Unfortunately I'm slow and don't understand lua as much as it seems.

So I copied the function(s) into my code, therefore it looks like this

So now the issue is using that "components" variable, which was returned within the function "getRainbowRGB(num)". Using it directly within the xyz of the local color function I had trouble with before just broke the game. I'm trying to figure out how to use the components[1], components[2],components[3] in my RGB values. I have the solution in my head though I can't seem to pull through with it. May I have the last bit of help?

Thank you so much!

 

Unfortunately that didn't work.

I created the time variable and put it as my input for the getRainbowRGB function, also I incremented the time by dt, (on line 39, I just put time = time * dt, instead of time = time + dt because I tried both, and they still didn't work out. In game, the input works, though it changes to a very specific red/black color, with no dynamic change at all.

 

My god it works. Thank you so much for all your help man. I appreciate all of your time. Can't thank you enough bruh. If you need anything, I'll try to offer a helping hand. Anyways, have an amazing day!
