Thing_Spawn Custom Actor

What's the best way to make a custom actor spawn? I need it to spawn silent and to be able to spawn it repeated times. I use DB2 with UDMF for Doom - I modified some files to include the custom actor earlier, but this didn't seem to do the trick..

Oh, the item I have has its own custom spawn ID - which I try to use when spawning

Use SpawnSpot, or a similar Spawn function from the table at the bottom of the wiki page. You put a classname as its argument, not spawn number. The function must be called from an ACS script, not from a linedef, though.

Ah ok. I hoped there was a way allowing it to go without a script. But thanks anyway :)

No way to simply add Spawn ID or actorname in UDMF format for a thing_Spawn?
It seem so likely that it should work, just that I havent gotten it to by the usual ways.. Since Doom calls for ID's spanning up to 255 - and never using anything higher than 15x itself, it opens for up to 100 spawn-ID's to be tagged to new items and allow for execution if I just knew how to get the ID passed onto the editor :)

Look here: http://zdoom.org/wiki/Actor_properties and find "Game" and "SpawnID". Yes, you can set them in DECORATE for custom actors. But it's unclean, as you're limited to values 1-255 that don't interfere with existing numbers. Read this: http://zdoom.org/wiki/Spawn_numbers

Thanks a lot. I know many of the things can be done with some neat scripts. But I didnt want to wrap my head into all the code as I already have spent weeks on all the lines of code in my Decorate, SBAR and other files. But it seem it's the way I have to go with some things. I made it work now using the linedef to execute the Spawnspot you mentioned earlier. And it went a lot smoother than I'd expect it to..

Thanks a lot for the help - you should get a medal for all the effort on the forum ^^ I see you answer questions in lots of posts, its apreciated :)

Well, you can use line specials or actor specials to spawn stuff. Note how in UDMF you can use the arg1str argument to use a class name instead of a spawn number.

Also, in recent development builds, you can redefine spawn numbers in MAPINFO, without having to change the actors.

Hm, but the Arg1 is used for 'MapSpot Tag' .. Or am I mistaken what you mean by arg1str? I tried also to make a new property with that name and define but crashed DB2 this way - so seem not right. What you suggest seem like the perfect solution if I should solve it without a script - but I somehow get it wrong :)
