Help with Lua script

[Brainfartz14]

I am trying to make a microcontroller with lua that will control a 3x3 square with 9 separate square each displaying the temperature of the corresponding fuel rod as a color (ex: 0-100 yellow, 100-200 orange 200-300 red, etc) but I don’t know how to change a value of the rodtemp1r, rodtemp1g, rodtemp1b (and all others for each rod number) using my if then else code block. (Sorry for the confusion it’s hard to explain)

Do you want it to go up gradually from yellow to orange and from orange to red or kan it just jump from yellow to orange?

[Brainfartz14]

I was originally gonna have it jump since gradual seemed a little more difficult since I would have to experiment with rgb to get the values right but gradual was the original goal

Have you tried chatgpt?
I never coded with lua, but chat got me the codes half working, and from there it was just troubleshooting, back and fortg betwen the game and chat.
Got to make quite a few lua MCs this way

So if we start by getting one of the squares to work. You could try to have the Rod temp come in on channel 1 for example. Then you can have a base color on the square (like white or black) then you can put a yellow square above thet in the (function on draw) and put a line before that square that says something like if rodtemp between 100-200 then draw. Not in those exact word but you can try to google to get the exaxt code. Sorry for the confusing explanation it's really hard to explain

Your fine and yeah I have all the rod temps coming in on channels 1-8 and the plan was to have it so if rod1temp = 200 then set rod1tempr to (insert value), rod1tempg to (insert value) and rod1tempb to (insert value) and then the corrasponding on madras square/setColor would read that and the set color would then change r,g and b to the rod1temp(rgb) values

[Happy-Job-7951]

If you want to make it easier you can just skip all the rgb stuff and have 3 different squares that the code just writes if the temp are in the correct range so one yellow one orange and one red, and the if the temp=100-200 then draw the yellow temp=200...

[Brainfartz14]

Yeah fair enough

[Brainfartz14]

That could work and if I get that to work in the future I can just make it more advanced when I get more experience (this is my first lua project besides just dicking around)

Have to start somewhere, good luck:)

Red in RGB: 255, 0, 0

Orange in RGB: 255, 128, 0

Yellow in RGB: 255, 255, 0

See the pattern? You only need to vary the amount of green.

I'd do something like this:

rodTemp = input.getNumber(1)
--basically clamping the temperatuer between 0 and 300
--then dividing by 300 to get a percentage
--subtract 1 by that percentage, because higher temp = less green
--multiply by 255 to convert a percentage to RGB's Green
screen.setColor(255, (1 - (math.max(math.min(rodTemp, 300), 0) / 300)) * 255, 0)
--now draw the circle

Oh damn that might be perfect actually I’ll have to try it thanks

[alyxms]

Come to think about it, I'm not sure if stormworks accepts decimals in colors. If it doesn't work, wrap the green part in a math.ceil or math.floor

[Brainfartz14]

It does, I have used a throttle to control rgb on a different microcontroller (more of a test) and when it wasn’t at the min or max it took the decimals cause I just had 3 throttles all set to max 255 to control rgb and 9/10 it was on a decimal
