" R_ProjectSprite: invalid sprite frame " error on a 1-frame object

[DynamiteKaitorn]

So I'm trying to edit the box of ammo item to have a new texture. The weird thing is, the game crashes and says I need to provide all of the frames, despite the fact that the box of ammo only has ONE frame (Ammo A 0). I have the correct frame provided and it's offsets shouldn't crash DooM (I even tried using the original object's exact frame offsets to no avail).

And you're sure it crashes on BULBA0, and not on SS_START?

 

I notice you have an S_END before that, and FZNFB0 matches the pattern of a sprite name. Are you having two different sprite namespaces in the same wad, one after the other? If so, it's probably the explanation, as I can see that confusing the merge algorithm. Try deleting those S_END and SS_START lumps that are between FZNFB0 and BULBA0 ; I suppose you have another SS_START lump even before.

Run chocolate doom using -merge instead of -file.

engine?

lump listing?

No idea what "lump listing" is. :l

The list of lumps. A screenshot of your wad opened in SLADE could have done the trick if there aren't too many lumps.

 

I figure the problem isn't the ammo box lump itself, it's vanilla's inability to have separate sprite namespaces. So, as andrewj said, use -merge.

I've been using -merge for a little while. Same issue. :l

 

Also I decided to test by using the default name of the ammo box. Same result...

You can’t have any more sprites after an S_END lump. In terms of sprites, vanilla ignores everything that comes after S_END. If you’re using custom sprites in a vanilla wad, it’s good form to have SS_START as your first lump, then all your sprites, then S_END. It looks like you have two S_END lumps which will also confuse the vanilla engine iirc.
