Unhandled Exception in ER

[Lazarus.]

Windows testers and anyone else reading TM's beta call thread may know that Echoes Renegade has been delayed by some very strange bugs resulting in unhandled exceptions for Windows users. Imban and I have both experienced crashes in the same area, and the problem has been traced to a seemingly harmless place_monster call. However, we are at a loss as to why BOA is suddenly objecting to such a frequently used call.

 

Pleas to Jeff Vogel have fallen on deaf ears, swearing and cursing has left us only with dry throats, BOA remains unrelenting in its inexplicable crashes. Here is the code in question, hopefully some wise spiderwebber out there will have better luck with it. This is one while statement out of 6 that appears in the town's start_state, the other 5 are just duplicates with different locations for monsters to spawn, so I posted just one. Ask TM, myself or any other tester if you need the full version of the script for some reason.

 

Code:

	if(get_flag(15,1) == 11){		if((((get_flag(19,1) == 0) && (get_ran(1,0,1) == 1)) || ((get_flag(19,1) == 1) && (get_ran(1,0,3) < 3))) && (get_flag(25,1) < 34)){			sld_typ = get_ran(1,0,8);			if(sld_typ < 4)				place_monster(24,8,6,0);			if((sld_typ >= 4) && (sld_typ <= 6))				place_monster(24,8,132,0);			if(sld_typ > 6)				place_monster(24,8,184,0);			pcs = 86;			telep_ok = 0;			while((pcs <= 119) && (telep_ok == 0)){				if(char_ok(pcs) == TRUE){					if(get_stat(pcs,27) == 0)						telep_ok = 1;				}				if(telep_ok == 0)					pcs = (pcs + 1);			}			if(telep_ok == 1){				alter_stat(pcs,27,1);				rctx = char_loc_x(pcs);				rcty = char_loc_y(pcs);				put_boom_on_space(rctx,rcty,2,0);				force_instant_terrain_redraw();				run_animation_sound(10);				inc_flag(25,1,1);			}		}

Good luck.

I had similar problems with UE until I did something odd. Remove any stray files from the BoA directory or the data directory that could possibly be duplicates of those included with the scenario. I was getting an error every time I opened DwtD, but it disappeared when I cleaned up the directory. Actually, since I cleaned them up, I've had NO UE errors.

 

Edit - What I'm getting at is that Windows has trouble when it is presented with two identically named files from which to choose. Thus the UE. Eliminate its confusion.

 

Hope that helps...

What did Jeff say? Did you get a response?

[Imban]

TM told me yesterday that Jeff hadn't responded to his e-mails at all.

[Kelandon]

That means that he should probably e-mail again.

[Nioca]

I can't see anything wrong with it, except for a missing bracket. I doubt that would cause an unhandled exception, though.

 

Do those creatures use any sort of unique script? It might not be this script, but something in the creature's script that is causing the UE.

 

EDIT: typo.

Another idea, during the testing of AGB, a few people got unhandled exceptions because of graphics files... If BoA is being pointed to a wrong custom graphic, or if there are duplicates, as Salmon said, then the whole edifice comes crumbling down.

[Kelandon]

Oh yeah, that reminds me. Setting the cr_small_or_large_template improperly causes crashes, but these crashes may not occur the first time the monster appears. The first thing I'd check here is graphics, and part of checking that is checking cr_small_or_large_template.

 

All known causes of UE are here , at the bottom.

Ok the error is fixed. The problem was that the spawned creatures used a slightly altered version of groupnpc which added them to their group and sent an alert to their group in the Init_state. Once the group they were being added to reached maximum capacity (20), they started sending alerts to nobody, which crashes Windows users but just does nothing for Macs.

 

Thanks for the help. And remember kids, don't send alerts to nonexistant groups.
