Hello, I have seen this message for many plugin errors.

L 12/03/2012 - 19:05:43: [SM] Displaying call stack trace for plugin "admintag.smx":

What exactly does it mean?

[Sheepdude]

Well, it means it backtraced the occurrence of the error through its parent functions. It's not very useful to know without the lines below it that tell what functions were called and on what line the error occurred.

[vodka00]

Okay I see, yes I have those lines. It helps me, yep.

What about

return Plugin_Changed;
return Plugin_Continue;
return Plugin_Handled;?

It seems to me that they all do different things in different plugins.

I'm not an expert on this subject, but I think this is the hierarchy:

Plugin_Continue
Plugin_Changed
Plugin_Handled
Plugin_Stop

You can return Plugin_ values in functions that are declared with an Action: tag (typically, events and timers). If you want to do stuff and then have other plugins and the game logic to carry on normally, use Plugin_Continue. Otherwise, you would use Plugin_Handled or Plugin_Stop to block further actions in that event from being taken, but from my experience how and if those actions are stopped depends on the event and on the plugins.

Repeating timers also use these return values, to continue iterating a repeating timer, return Plugin_Continue, otherwise use Plugin_Stop from within the timer callback to stop it from repeating.

Oh and Plugin_Changed is used if you modified an event and want it to continue normally, but with the modified values. For instance, if you use SetEventInt("canbuy", 0) on an enter_buyzone event hook.

In forwards, Plugin_Handled and Plugin_Stop actually do have a difference. Plugin_Stop immediately stops the forward and no further plugins have their handlers called. Plugin_Handled tells it to not run the game function, but allows other plugins to continue processing the forward.

Note: This applies more for private forwards; global forwards usually don't return Action.

[Sheepdude]

Yeah, what Powerlord said. What I meant was for some events you can return Plugin_Handled or Plugin_Stop and it probably won't work the way you want it to (such as for player_hurt).
