| Summary | 0002486: *** ERROR: Tried to spawn a class-less actor |
| Description | *** ERROR: Tried to spawn a class-less actor
Can we have more detail about this error ? I mean some info, where to start search for a problem, not just "trial-and-error method". Actor and string would be useful.

FYI that error happens when it literally tries to spawn an actor without a class. So there's no information, no class name to give. You've run into a bug and we need more information to fix it. |

I found where is a problem.
I used nonexistent "bloodtype" in this actor. Minimal example wad uploaded.
To reproduce:
1. load test_classless.pk3
2. summon testdemon
3. shoot at it.
Online - server kick all clients and restarts with "Tried to spawn a class-less actor" error.
Offline - all fine.

Found the culprit. In the past the server went to spawn the blood actor if bloodtype <= 1 check didn't satisfy. Now it goes in there even if bloodcls is NULL.

Glad that my mistake helped to find zan's problem, but that ticket is about this error in global meaning.
I mean: why error, not warning (can we ignore it, write to log and move on ?) Its not like "nothing trying to spawn nothing" its more like "something trying to spawn "bad_actor"". Can we have more detail about what courses it to happen (DECORATE\ACS string, or actor that trying to spawn "bad_actor") ?
P.S. Similar question about missing actor for model in MODELDEF (why error instead of warning?), but i presume, 1 problem - 1 ticket.
P.P.S. I'am newbie here so, accept my apologies, if I asking something on what the answer is obvious.

The engine spawns actors using actor classes (e.g. spawn an imp using the imp class). The error happens when the engine is creating an actor and find out that the actor class is missing. So it finds itself trying to spawn an actor without any idea what actor needs to be spawned. It would need to spawn *something* in order to continue execution. I guess it could spawn exclamation marks of doom instead but it wasn't me who made that decision (this behavior comes from ZDoom, even though it's a Zandronum bug which manages to trigger it).
MODELDEF is something completely different. I believe there's already a ticket for the issue you describe, I'm not very familiar with MODELDEF myself. |

The crash should be fixed now. Dusk is right about the error message. If the engine encounters this problem, it really doesn't know what it was supposed to spawn leading to a very generic error message. |
