Sprite disappearance when billboard turned on

[Nash]

When you look fully (100%) up or down and fire your plasma rifle or BFG (or any projectile weapon), the sprite isn't visible.

Shift your pitch a little and they will appear.

Interesting finding, but this has nothing to do with the billboard feature and also happens in GZDoom. Just fire a few plasma shots, freeze the game and fly above them looking nearly straight down. The plasma sprites near you crosshair vanish.

You're right. I'll post report this bug at the GZDoom forum then.

Actually this was done intentionally because otherwise you'd see the projectile overlaid over the weapon sprite in its first frame.

Right, that whole depth testing business...

this is due to the shots originating from the player itself, and not the "gun", right?

[Graf Zahl]

Precisely. The missile is spawned at the player's center.

Would it be possible to sort of hack around this by making the very first frame invisible and then making it appear again like in the very next tic? I don't know how the engine works... just tossing some ideas around...

Should be a little better now.
