Storing stuff in 'level' is perfectly fine.

'Self' was never allocated to begin with, since onTimeLimit was not called on anything! I'm still not sure what object or entity you're expecting 'self' to be.

It had to be allocated since promod's dm.gsc references it as well as my script works 100% when calling the final killcam in the same method evoked at the playerKilled event. All references being self there.

I've debugged it for several days and self is fully existent up until the timer is up. Self even stays if the match is point based. So it is something with the match timer itself that trashes self.

'Self' is a special local variable. It differs depending on the how the function was called. 'Self' will be the object or entity that the function was called on.

Since onTimeLimit was not called on anything, 'self' will be undefined (actually I think it uses the 'self' from the function it was called from, which would be 'level' from the checkTimeLimit() function and 'level' is not an entity).

playerKilled is called from _callbacksetup::CodeCallback_PlayerKilled(), where 'self' is defined as the player. So the 'self' in playerKilled is the player who died. 'Self' will change depending on which player died.

Here's some code to show that 'self' in the doStuff() function can be 2 different things, a script_model and a player:

blah()
{
	model = spawn("script_model", (0,0,0));
	model doStuff(); // 'self' will be the model

	players = getentarray("player", "classname");
	players[0] doStuff(); // 'self' will be a player
}

doStuff()
{
	self setModel("knife");
	iPrintlnBold("I am a " + self.classname);
}

When the function ends the variable 'self' will no longer exist.

Everything you are experiencing is correct and expected based on how you've coded it.

I too overwrote the player killed method and have my own residing in my modified dm.gsc. The self that it references is in my dm.gsc not globallogic.

Same idea still applies, 'self' is local and will change depending on who died.

'level' is a global variable, using 'level' in any function will access the same object.
'self' is a local variable, it can be different each time a function is called, even if it's the same function being called or a different function.
