Is there any built in smoke testing tool?

Solution 1:

There are smoke training maps, open the Workshop and search "smoke training". They are setup in such a way that when you join you have unlimited nades and can see the trajectory.

Alternatively you can run few commands on a local "Offline with bots" to play around as much as you want.

// Server configuration
sv_cheats 1
mp_limitteams 0
mp_autoteambalance 0
mp_freezetime 0
mp_roundtime 60
mp_roundtime_defuse 60
mp_roundtime_hostage 60
mp_maxmoney 99999
mp_startmoney 99999
mp_buytime 9999
mp_buy_anywhere 1
ammo_grenade_limit_total 5
sv_infinite_ammo 1
bot_kick
mp_warmup_end

// Grenade trajectory commands. Note – these don’t work on dedicated servers.
// For dedicated servers, use SourceMod plugin “Nade tails” instead.
sv_grenade_trajectory 1
sv_grenade_trajectory_time 10

// Show bullet impacts
sv_showimpacts 1
sv_showimpacts_time 10

mp_restartgame 1

// Print out so we know the config has been executed.

Say “Practice config enabled”

How to install the config on your computer

1. Download the config file or create a text-document and paste the config file into it. Name it something along the lines of “practice.cfg”. The .cfg extension is important.
2. Locate your Steam folder and then go to “…\Counter-Strike Global Offensive\csgo\cfg”
3. Move the config file into this folder.
4. Start CS:GO and select “Play offline with bots” to start a local server.
5. Open up your console and type “exec practice” (or whatever you named the config file)
6. You’re good to go!
