Call Function on Variable Change
I'm working on a custom server tool for a game I'm trying to trigger an event when a variable in the memory changes a certain way.

Example of what I'm trying to do in a timer

 
Code

int client0alivevalue = memory.ReadByte((IntPtr)address + (clientsize * 0));


if (client0alivevalue == 0 then changes from 0 to 1)
{ do something }



So when client0alivevalue = 0 the client is dead and when it's 1 the client is alive. When the client dies and then respawns I want to trigger a function hence the example: if (client0alivevalue == 0 then changes from 0 to 1). I only want to trigger said function when the client0alivevalue changes from 0 to 1.

I hope this makes sense.

Subscribe to an eventhandle and have this code: http://stackoverflow.com/questions/5...lue-is-changed
Hope it solved some parts of your problem.

You could also do a thread event that grabs the integer repeatedly. But that would take up alot of CPU.
So i'd recommend subscribing to an eventhandle.

I suggest you to have your code injected into the target process. That will make it easy to simply check the value every x milliseconds without requiring alot of resources

Properties won't do him any good if the process is external and he doesn't have the code. Reading from memory in a loop isn't all that CPU intensive, just don't query too often. 100 milliseconds between checks should be fine for *most* purposes.

And even if he did it in a continuous loop without any sleeps, it will only use like 20% of your CPU. I tell you this from experience...
