Hey developers. When I test my game in studio, I am getting spikes of ping and CPU almost every 2-3 seconds. So I am trying to see what excatly is causing that lag. My game though is quite huge, so like I can’t just look through ‘all the scripts’. I need to narrow it down to if it’s a modeling issue/render issue, or a scripting issue and where it’s coming from. Now I know that there is tools for this, but I don’t understand them well, such as the developer console. So any help on figuring out the source of my lag is appreciated!
So fire up the game, press F9 and head in to the Dev console. In the top-right, there is a drop down, select scripts & this will show you all (green) and sleeping(?) scripts:
You need to consider both the Activity (%) which if it is above 1 frequently needs to be reviewed and consider how much work the script is doing and if it is needed to actively fire/work as much as it is.
Secondly Rate shows how frequently the script is firing. In my example ‘Animate’ has a high Rate, but low Activity. It is controlling the NPC animations as they move and change state from Idle to Walking.
This game did have a problem with lag with projectile throwing. When the projectile is spawned, it contains a script which controls it motion & collision detection. I noticed the Rate for this script increased over time so I knew there was an issue. I discovered that I was not disconnection the projectile motion loop so the script kept running. Nice discovery solely using this console
