We can not use findRotation, because we need left or right angles (it can be -10>n then it's a left turn, if it's 10<n then it's a right turn, if it's between -10 and 10 it is nothing) We have a table with precalculated values (the need field is what we need), but we get different numbers (got field) function getAngle(x1, y1, x2, y2) local angle = math.atan2(x1, y1) - math.atan2(x2, y2) if angle <= -math.pi then angle = angle + 2 * math.pi usedAlg = "hoz" else if angle + 2 * math.pi <= math.pi then angle = angle - 2 * math.pi usedAlg = "min" end end return -math.deg(angle) end pass fail || need: 13.532079523427 || got: -346.46792047657 fail || need: 368.80375654813 || got: 8.8037565481247 fail || need: 270 || got: -90 fail || need: -85.150542731867 || got: -85.150542731865 pass fail || need: 13.532079523427 || got: -346.46792047657 pass pass pass pass but it does not work

Yes.. works perfectly, but not for my code. (Don't get all directions (left/right - like highways exit)

Hello dear reader! I'm searching a math function to get the perfect angle. I have one function, but it not whole. function getAngle(x1, y1, x2, y2) while true do while true do if math.atan2(x2, y2) - math.atan2(x1, y1) <= -math.pi then end end end while true do if math.atan2(x2, y2) - math.atan2(x1, y1) + 2 * math.pi > math.pi then end end return math.atan2(x2, y2) - math.atan2(x1, y1) + 2 * math.pi - 2 * math.pi end Thanks the replies. (The findRotation and other simple functions not good for me.)

I'm now tried the module in MTA SA 1.4 server and successfully loaded. What the problem with 1.5.4 server?

I'm using it in client side, but tried it in server side. Every side return the "attempt to call" I don't know what the problem. I'm using Windows 10 Pro 64 bit, MTA SA server 1.5.4. The console show the module successfully loaded.

I see the message in console. I tried to add mtaconf. Start server and the module is loaded, and tried the loadmodule command but nothing changes. The functions dont work.

Yes. The console/debugscript didn't write anything error message. I tried the 32 and 64 bit modules, but same problem.

I'm loaded the module, but i get "attempt to call global" error when i try to use those functions.

Try this: nitroShader = dxCreateShader("nitro.fx", 0, 100, false, "vehicle")

Yes, and this shader makes it. Only scripting needed.

-- Use custom font and set antialiased. dxCreateFont("path.format", size, false, "antialiased") -- for me work all times very good with my responsive multiplier

I'm tried to compile vehicle nodes because i'm curious.

No errors. I see other server compiled 5mb lua file (vehiclenodes). The compiler gives this: ERROR Could not read file

Hello reader. I tried today to compile one big lua file (2 to 5 MB) but every luac compiler return error. I tried the https://luac.multitheftauto.com/ and the Windows batch file, but the result not changed. Thanks any answer.

Hmm.. My code is work very well for myself.

Thanks your answer, but this function is same problem. I now try to add previous road angle to every next road angle and then calculate it.

I tried it, but the same problem.
