Anyone know what is causing csgo srcds to freeze?

Re: plugin causing csgo srcds freeze
 
Maybe too much stuff OnPlayerRunCmd, this one runs for every client at every tick.

Perhaps you should check the buttons first before doing all stuff

How would I do that?

Users need avoid using OnGameFrame and OnPlayerRunCmd, if you not have a clue how those works.

Event repeating timer with 0.1 seconds is better solution.

Can you explain how to do it here for this plugin?

Basically, you will have to create a timer, you can find how to create one in the wiki.

https://wiki.alliedmods.net/Timers_(...Mod_Scripting)

And move your logic from "OnPlayerRunCmd" to the timer, inside a for loop through all valid clients (IsConnected)

The only thing you "don't" have ready to use is the client button, but is possible to get that with some basic functions (GetClientButtons)

This is the basis, if you don't know what I'm talking about I believe you won't be able to do it on your own and will need a code "ready to go".

I tried to understand what you sent but there is nothing in the link which you have sent. I apologize for my lack of coding knowledge.

Re: plugin causing csgo srcds freeze
 
Avoid declaring variables inside frequently ran functions. Use global variables (either by declaring your variables outside or by using the 'static' keyword behind a variable).
Ex:

Code:
static float oldyaw;
oldyaw = g_flOldYawAngle[client];
See https://wiki.alliedmods.net/Introduc...7#Local_static

OnPlayerRunCmd is ran once every tick for every player. Assuming you have 20 players and your tickrate is 64, that makes 1280 calls per second. When you have that many calls, do as little checks and calculations as you can. Variable declaration is expensive.

Some kind of forum bug, btw with a simple google search you would have found

It doesn't seem to be a good one in this situation, they seem to want to emulate strafing. For more precise results, something that runs every frame is needed.

"SimulateStrafingTickrate()"
