Removing Grenade Entity Before Explosion

Is there any known bug with removing a grenade entity multiple times before it explodes, like making the game crash or something?

I'm working on this plugin where you can throw a camera like a grenade for recon. I take a smokegrenade and right before it detonates I remove it and place an entity there that acts as the camera and I see what it sees.

About several minutes into the game it sometimes crashes for no apparent reason. I was either shooting a bot or just walking around minutes away from the last cam I threw. I'm not sure which part is the problem since it doesn't create a log, only a minidump that I can't read. And my best bet is the removal of grenade entities. Anyone have relevant information would be much appreciated...

As I've said it only creates a minidump. No error logs...

I see how the thread can be related. But I only asked if anyone had an idea if removing grenades would cause the game to crash. The thing is 90% complete and I'm not too keen in converting the whole of it to Okapi. But you gave me an idea. I found the approved Teleport Nade plugin here and will try to emulate that instead, thank you...

Sorry. Not that I don't want to share, but the thing in embedded into a larger plugin. And I know you would like to have the whole thing but I doubt anyone would take the time to sift thru it.

I know, it seems dumb, asking for help without posting code. But I only asked if anyone had any idea if this would make the game crash. Nevertheless, Craxor gave me an idea for a possible solution so I think we're all good.

PS: If you're wondering about my code, the gist is it's hooked on FM_SetModel. Inside there's a timed task that removes the grenade entity with remove_entity(). And the timer is set a few milliseconds before detonation. I've also made liberal use of pev_valid...

Alright, a solution don't use remove_entity, use instead the other method which is by setting an entity flags to FL_KILLME then call entity think, its more reliable safer way !

That's definitely good to know, thanks. I'm familiar with FL_KILLME but it never worked for me. Probably because I'm unfamiliar with calling entity think and didn't know you had to do that.

I made this stock. Did I do it properly?...

PHP Code:


		
			
stock kill_entity(ent)

{

    set_pev(ent, pev_flags, pev(ent, pev_flags) | FL_KILLME);

    set_pev(ent, pev_nextthink, get_gametime() + 0.01);

    dllfunc(DLLFunc_Think, ent);

}

Re: Removing Grenade Entity Before Explosion

Yes, but you don't need to set up next think

So basically remove this...

Code:

set_pev(ent, pev_nextthink, get_gametime() + 0.01);

Roger that. It's working now but I haven't had time to do an extensive so I don't know yet if it fixed the crashing. If it still does it's probably other stuff that's causing it. But it's good to know, I'll be using FL_KILLME instead remove_entity from now on, thank you very much!...
