NEW Advanced Lua Radar Tutorial - Step by Step Guide - Part 1 - Stormworks

[@TheBrilliantShadow]

Great timing to teach us intimidating tech that we'll need in the future! Looking forward to Part 2! May I add two notes for your next video? 1) Nil'ing your index at full rotation has the major downside that targets close to rotation end will be visible very briefly. I would suggest to bind the index to the rotation. This allowes you to clear the index at access first, then write any accuired target. (downside may be, as you saw in this video, that there might me a de-sync in the rotation number when the if >= 0.5 sets a new default after first pass - that needs to be addressed) 2) Add Alpha Values to the dots, that decay by tick. Looks super cool! You can set the start value to a twin-array (same index x2) and reduce it every tick by 1.

[@leemiles3995]

please make an updated version of this tutorial, it was heartbreaking to get halfway through this and then realise that the radar part is different to mine.

[@Wolfpack611]

Hey, just want to let you know, the starter boat (can be found in presets) still had the old radar, so just take it off of it (control+left click) I dont know if the tutorial still works for it or anything because I havent tried it

[@darkangelgaming7787]

yea. i saw that too. they changed the radar basic to have a radar number out, input in and composite out. i have no idea how its going to read from the composite out since im so new to this game. though, did notice it has 8 channels on it i think.

[@leemiles3995]

@@darkangelgaming7787 you can read from the composite out using a 'composite read (number/on&off)' in your microcontroller, then you can select which channel you want to read from. the channels range from 1-32, and are basically 32 number, and on/off inputs squeezed into one. you can tell what channels mean what by hovering over the composite logic node on the radar. Hope this helps...

[@pheocalo4073]

Sir i tried it.. and my target didnt pop up on the screen. I follow the code of your lua. Still no red dot

[@redpug5042]

not bad, i use a similar system, however, each table value stores a distance, rotation and tick counter. every tick, the counter for all points is increased, when that tick count is as long as one rotation, it gets deleted. I also prefer to draw rectangles with a width and height of 1 because it's less laggy than circles, and it looks basically the same.

The new radar has only 2 funtions, radar on/off and rotations! This is where i can't go futher. rotations, on the radar, is a output. In the microcontroller we need to make a output Radar Yaw but i can not connect it on de radar. And now comes a strange thing: the radar is rotating on screen, but is not conected with the output Radar Yaw. Please can you help me and explain why and how i can go futher?

I followed this almost to the letter (adjusted numbers to fit the screen) and now I'm stuck halfway through. My Lua says "10: syntax error near '+'" and I have no idea what's going on.

For anyone confused with the code which does the rotation of the line I found a way basically x1 = w/2+h/2* math.cos(((rotation*1.57)*4)-1.57) y1 = h/2+h/2* math.sin(((rotation*1.57)*4)-1.57) where rotation is the value of the radar's rotation node and w and h are the screen's width and height respectively explanation : [multiplying rotation with 1.57 turns the rotation to radians] [multiplying it by 4 makes sure that it turns 6.28 radians] [subtracting 1.57 makes sure that the line starts from the top of the screen] In my opinion, I think this is the easier way

[@Izz4cc]

Here's my full code :- w1=0 h1=0 -- Tick function that will be executed every logic tick function onTick() rotation = input.getNumber(30) -- I wrote the rotation value into channel 30 because 1-28 channels are being used for radar and then 31,32 are the inputX and inputY for touchscreen x1 = w1/2+h1/2* math.cos(((rotation*1.57)*4)-1.57) y1 = h1/2+h1/2* math.sin(((rotation*1.57)*4)-1.57) end -- Draw function that will be executed when this script renders to a screen function onDraw() w = screen.getWidth() -- Get the screen's width and height h = screen.getHeight() w1=w h1=h --Makes width and height accessible by the onTick function screen.setColor(0,255,0) screen.drawCircle(w/2,h/2,h/2) screen.setColor(0,200,0,125) screen.drawLine(w/2,h/2,x1,y1) end

I'm really curious how to make LUA works for property selection of microcontroller because they are not even attached to anything. Therefore, it used LUA to make it works. For example, adjust the AFR modular engines without connection to any logic. But it used LUA.

you use property.getNumber("name") or property.getText("name") in the lua script, just as you would use input.getNumber(channel)

They change the radar, now, the radar does not recive imput, it only output angle of the dome, and the target data is given via composite, up to 8 targets, im not a programer, but so far manage to change the display so the line move with the radar angle (just ignoring the speed and angle part, and change the "a" for put an imput line in the "radarA" line.

[@EnderMalcolm]

I have no idea why, but my Stormworks must be messed up. I followed the tutorial precisely, and my radar is pointed in a really weird direction, only detects one thing, and it's not lined up at all. It also doesn't show the distance properly, so not a clue why it's gone wrong.

[@GoogleUser--jk1db]

[@cdeshaw1986]

Loved this game up till this point. Taking calculators out to play a game is where I draw the line. If the combat was great it would be worth the hours these creations take, but the combat is horrendous at best. Love the idea, but they should of stuck with Search and Rescue and made a new game for fighting in my opinion! I think Radar should be a standard item, not something we have to literally create with code. Imagine having to code the defibrillator? I think this game would achieve a lot more success by making items like Radar automatically function by just hooking it to a screen. I cant tell you how bad I want to make military equipment to fight the AI, but realizing how poor the combat is, I can not dedicate the time to learn all this. If radar is this hard, how hard is targeting? Also the creations I have used with Radar and such, seem very touch and go. More do not work than do. I'm not trying to just be a downer here, It is just that all the weapons DLC are useless to me without radar and targeting systems, and I can not be the only one lacking the patience to learn that much for the sloppy combat as the reward. I learned to make a nuclear reactor function in this game, but the deeper logic stuff I am absolutely lost, and math is my best subject! It does not help that there is like no tutorial for the logic in the game. Thank gosh for you and your channel, you have taught me far more than the game is capable. Now to watch this video for the 5th time to see what I am just not understanding here!
