Description

Pretty much what the subject states; the Arch Vile disappears during resurrecting a bad guy, before appearing again after resurrection.

When it goes to resurrect, the Arch Vile enters VILE_HEAL1.

I want to add onto this report and say that it happens during single player too, not just multiplayer. I saw it happen while running around levels in TNT and Plutonia with the latest build.

The Arch Vile's resurrecting sprites uniquely use the special [,/ and ] characters. I believe Dday's support for these characters (in wad at least), has been broken.

As a test I altered the Arch Vile's resurrecting states to use the first few sprites of the Imp (i.e A,B and C) and the Arch Vile no longer disappeared when resurrecting.

HeXen also uses sprites with these special characters, for both the last gib death state and the ice death state, of the Cleric.

When one gib's Traductus (Cleric Boss), Dday currently segfaults when it reaches the mentioned last frame. I haven't tried to freeze him, but I assume the same crash will occur.

I managed to find where the crash is occurring with Traductus (savegame attached). The associated commit 04452f9dc9e avoids the crash in the release build, however does nothing to address why the sprites are not being found.

#14 Updated by skyjake about 9 years ago

I've discovered that the reason why the sprites are missing is that findTextureForAnimationStage() fails with a MissingManifestError for URIs "Sprites:CLER[0" and "Sprites:CLER\0". This is likely due to a missing decode/encode of percent encoded URIs (somewhere).

I'm guessing the problem lies in the sprite Texture generation in ResourceSystem. The name should be encoded when inserting these into the PathTree.
