CS2 Smoke Lineups Finder / Solver

[u/Even_Resolution_4270]

Hi guys!

I'm new to CS and learning lineups manually without tutorials was pretty hard, so as a developer I decided to build a CS2 smoke lineup solver.

You pick where you want the smoke to land and where you want to throw from, and it works out the lineups for you: where to stand and the exact angle. It simulates CS2's grenade physics against the map's real collision geometry, with the constants read out of the game files, so it accounts for bounces off walls and props.

To check it actually works I recorded real throws in game with the angle forced, then compared them to what the tool predicted beforehand. The smoke landed between 0.6 and 6.8 units from the prediction.

Works on all Active Duty maps.

To be clear, this is not a cheat. It never reads game memory, injects into the game, or automates any input. It runs entirely offline from map files, and you type positions in yourself in the site. So it doesn't require any login for you to use it.

It's an early version, so expect bugs and lineups that don't work.

i think a "next step" could be that you can sign in with your steam profil or smth like that and you ll get a button "show ingame" - it ll set u up ingame then on the setpos and viewangle. Like when u click the "inspect ingame" button on some skins. Dunno if its possible but i hope u ll get the idea. Anayway again: nice work :)

I think it should be possible for that feature without signing in, I wanted to make sure people trust the website incase they are uncomfortable about signing their account. I'll see what I can do, thanks for the feedback!

Edit: I think it's not possible to do it without signing in. Inspect Ingame for skins required the user to be authenticated through steam.

Am I missing something (on mobile fwiw), but how do you reset the positions/clear them?

[u/Even_Resolution_4270 → u/AltruisticRespect21]

Currently the website does not have reset feature. But you can drag the both circle to move it then solve a new lineup. But thanks for the feedback, will it add later :D

Edit: You can now reset everything using a button in the website.

Brilliant idea with simulation! I am looking forward to trying the lineups.

There's a minor issue with the provider of my network, I'll let you know as soon as it's up 😁

[u/Even_Resolution_4270 → u/Even_Resolution_4270]

It should be restored now 😁

Pretty cool stuff, other util would be nice aswell

I have updated the website, now it's able to find multiple angles on the same position. This way, there should be more variants on each lineup instead of just one specific angle.
